It is + numbered 2 because it goes with version 2 of the ordinary GPL.] + + Preamble + + The licenses for most software are designed to take away your +freedom to share and change it. By contrast, the GNU General Public +Licenses are intended to guarantee your freedom to share and change +free software--to make sure the software is free for all its users. + + This license, the Library General Public License, applies to some +specially designated Free Software Foundation software, and to any +other libraries whose authors decide to use it. You can use it for +your libraries, too. + + When we speak of free software, we are referring to freedom, not +price. Our General Public Licenses are designed to make sure that you +have the freedom to distribute copies of free software (and charge for +this service if you wish), that you receive source code or can get it +if you want it, that you can change the software or use pieces of it +in new free programs; and that you know you can do these things. + + To protect your rights, we need to make restrictions that forbid +anyone to deny you these rights or to ask you to surrender the rights. +These restrictions translate to certain responsibilities for you if +you distribute copies of the library, or if you modify it. + + For example, if you distribute copies of the library, whether gratis +or for a fee, you must give the recipients all the rights that we gave +you. You must make sure that they, too, receive or can get the source +code. If you link a program with the library, you must provide +complete object files to the recipients so that they can relink them +with the library, after making changes to the library and recompiling +it. And you must show them these terms so they know their rights. + + Our method of protecting your rights has two steps: (1) copyright +the library, and (2) offer you this license which gives you legal +permission to copy, distribute and/or modify the library. + + Also, for each distributor's protection, we want to make certain +that everyone understands that there is no warranty for this free +library. If the library is modified by someone else and passed on, we +want its recipients to know that what they have is not the original +version, so that any problems introduced by others will not reflect on +the original authors' reputations. + + Finally, any free program is threatened constantly by software +patents. We wish to avoid the danger that companies distributing free +software will individually obtain patent licenses, thus in effect +transforming the program into proprietary software. To prevent this, +we have made it clear that any patent must be licensed for everyone's +free use or not licensed at all. + + Most GNU software, including some libraries, is covered by the ordinary +GNU General Public License, which was designed for utility programs. This +license, the GNU Library General Public License, applies to certain +designated libraries. This license is quite different from the ordinary +one; be sure to read it in full, and don't assume that anything in it is +the same as in the ordinary license. + + The reason we have a separate public license for some libraries is that +they blur the distinction we usually make between modifying or adding to a +program and simply using it. Linking a program with a library, without +changing the library, is in some sense simply using the library, and is +analogous to running a utility program or application program. However, in +a textual and legal sense, the linked executable is a combined work, a +derivative of the original library, and the ordinary General Public License +treats it as such. + + Because of this blurred distinction, using the ordinary General +Public License for libraries did not effectively promote software +sharing, because most developers did not use the libraries. We +concluded that weaker conditions might promote sharing better. + + However, unrestricted linking of non-free programs would deprive the +users of those programs of all benefit from the free status of the +libraries themselves. This Library General Public License is intended to +permit developers of non-free programs to use free libraries, while +preserving your freedom as a user of such programs to change the free +libraries that are incorporated in them. (We have not seen how to achieve +this as regards changes in header files, but we have achieved it as regards +changes in the actual functions of the Library.) The hope is that this +will lead to faster development of free libraries. + + The precise terms and conditions for copying, distribution and +modification follow. Pay close attention to the difference between a +"work based on the library" and a "work that uses the library". The +former contains code derived from the library, while the latter only +works together with the library. + + Note that it is possible for a library to be covered by the ordinary +General Public License rather than by this special one. + + GNU LIBRARY GENERAL PUBLIC LICENSE + TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION + + 0. This License Agreement applies to any software library which +contains a notice placed by the copyright holder or other authorized +party saying it may be distributed under the terms of this Library +General Public License (also called "this License"). Each licensee is +addressed as "you". + + A "library" means a collection of software functions and/or data +prepared so as to be conveniently linked with application programs +(which use some of those functions and data) to form executables. + + The "Library", below, refers to any such software library or work +which has been distributed under these terms. A "work based on the +Library" means either the Library or any derivative work under +copyright law: that is to say, a work containing the Library or a +portion of it, either verbatim or with modifications and/or translated +straightforwardly into another language. (Hereinafter, translation is +included without limitation in the term "modification".) + + "Source code" for a work means the preferred form of the work for +making modifications to it. For a library, complete source code means +all the source code for all modules it contains, plus any associated +interface definition files, plus the scripts used to control compilation +and installation of the library. + + Activities other than copying, distribution and modification are not +covered by this License; they are outside its scope. The act of +running a program using the Library is not restricted, and output from +such a program is covered only if its contents constitute a work based +on the Library (independent of the use of the Library in a tool for +writing it). Whether that is true depends on what the Library does +and what the program that uses the Library does. + + 1. You may copy and distribute verbatim copies of the Library's +complete source code as you receive it, in any medium, provided that +you conspicuously and appropriately publish on each copy an +appropriate copyright notice and disclaimer of warranty; keep intact +all the notices that refer to this License and to the absence of any +warranty; and distribute a copy of this License along with the +Library. + + You may charge a fee for the physical act of transferring a copy, +and you may at your option offer warranty protection in exchange for a +fee. + + 2. You may modify your copy or copies of the Library or any portion +of it, thus forming a work based on the Library, and copy and +distribute such modifications or work under the terms of Section 1 +above, provided that you also meet all of these conditions: + + a) The modified work must itself be a software library. + + b) You must cause the files modified to carry prominent notices + stating that you changed the files and the date of any change. + + c) You must cause the whole of the work to be licensed at no + charge to all third parties under the terms of this License. + + d) If a facility in the modified Library refers to a function or a + table of data to be supplied by an application program that uses + the facility, other than as an argument passed when the facility + is invoked, then you must make a good faith effort to ensure that, + in the event an application does not supply such function or + table, the facility still operates, and performs whatever part of + its purpose remains meaningful. + + (For example, a function in a library to compute square roots has + a purpose that is entirely well-defined independent of the + application. Therefore, Subsection 2d requires that any + application-supplied function or table used by this function must + be optional: if the application does not supply it, the square + root function must still compute square roots.) + +These requirements apply to the modified work as a whole. If +identifiable sections of that work are not derived from the Library, +and can be reasonably considered independent and separate works in +themselves, then this License, and its terms, do not apply to those +sections when you distribute them as separate works. But when you +distribute the same sections as part of a whole which is a work based +on the Library, the distribution of the whole must be on the terms of +this License, whose permissions for other licensees extend to the +entire whole, and thus to each and every part regardless of who wrote +it. + +Thus, it is not the intent of this section to claim rights or contest +your rights to work written entirely by you; rather, the intent is to +exercise the right to control the distribution of derivative or +collective works based on the Library. + +In addition, mere aggregation of another work not based on the Library +with the Library (or with a work based on the Library) on a volume of +a storage or distribution medium does not bring the other work under +the scope of this License. + + 3. You may opt to apply the terms of the ordinary GNU General Public +License instead of this License to a given copy of the Library. To do +this, you must alter all the notices that refer to this License, so +that they refer to the ordinary GNU General Public License, version 2, +instead of to this License. (If a newer version than version 2 of the +ordinary GNU General Public License has appeared, then you can specify +that version instead if you wish.) Do not make any other change in +these notices. + + Once this change is made in a given copy, it is irreversible for +that copy, so the ordinary GNU General Public License applies to all +subsequent copies and derivative works made from that copy. + + This option is useful when you wish to copy part of the code of +the Library into a program that is not a library. + + 4. You may copy and distribute the Library (or a portion or +derivative of it, under Section 2) in object code or executable form +under the terms of Sections 1 and 2 above provided that you accompany +it with the complete corresponding machine-readable source code, which +must be distributed under the terms of Sections 1 and 2 above on a +medium customarily used for software interchange. + + If distribution of object code is made by offering access to copy +from a designated place, then offering equivalent access to copy the +source code from the same place satisfies the requirement to +distribute the source code, even though third parties are not +compelled to copy the source along with the object code. + + 5. A program that contains no derivative of any portion of the +Library, but is designed to work with the Library by being compiled or +linked with it, is called a "work that uses the Library". Such a +work, in isolation, is not a derivative work of the Library, and +therefore falls outside the scope of this License. + + However, linking a "work that uses the Library" with the Library +creates an executable that is a derivative of the Library (because it +contains portions of the Library), rather than a "work that uses the +library". The executable is therefore covered by this License. +Section 6 states terms for distribution of such executables. + + When a "work that uses the Library" uses material from a header file +that is part of the Library, the object code for the work may be a +derivative work of the Library even though the source code is not. +Whether this is true is especially significant if the work can be +linked without the Library, or if the work is itself a library. The +threshold for this to be true is not precisely defined by law. + + If such an object file uses only numerical parameters, data +structure layouts and accessors, and small macros and small inline +functions (ten lines or less in length), then the use of the object +file is unrestricted, regardless of whether it is legally a derivative +work. (Executables containing this object code plus portions of the +Library will still fall under Section 6.) + + Otherwise, if the work is a derivative of the Library, you may +distribute the object code for the work under the terms of Section 6. +Any executables containing that work also fall under Section 6, +whether or not they are linked directly with the Library itself. + + 6. As an exception to the Sections above, you may also compile or +link a "work that uses the Library" with the Library to produce a +work containing portions of the Library, and distribute that work +under terms of your choice, provided that the terms permit +modification of the work for the customer's own use and reverse +engineering for debugging such modifications. + + You must give prominent notice with each copy of the work that the +Library is used in it and that the Library and its use are covered by +this License. You must supply a copy of this License. If the work +during execution displays copyright notices, you must include the +copyright notice for the Library among them, as well as a reference +directing the user to the copy of this License. Also, you must do one +of these things: + + a) Accompany the work with the complete corresponding + machine-readable source code for the Library including whatever + changes were used in the work (which must be distributed under + Sections 1 and 2 above); and, if the work is an executable linked + with the Library, with the complete machine-readable "work that + uses the Library", as object code and/or source code, so that the + user can modify the Library and then relink to produce a modified + executable containing the modified Library. (It is understood + that the user who changes the contents of definitions files in the + Library will not necessarily be able to recompile the application + to use the modified definitions.) + + b) Accompany the work with a written offer, valid for at + least three years, to give the same user the materials + specified in Subsection 6a, above, for a charge no more + than the cost of performing this distribution. + + c) If distribution of the work is made by offering access to copy + from a designated place, offer equivalent access to copy the above + specified materials from the same place. + + d) Verify that the user has already received a copy of these + materials or that you have already sent this user a copy. + + For an executable, the required form of the "work that uses the +Library" must include any data and utility programs needed for +reproducing the executable from it. However, as a special exception, +the source code distributed need not include anything that is normally +distributed (in either source or binary form) with the major +components (compiler, kernel, and so on) of the operating system on +which the executable runs, unless that component itself accompanies +the executable. + + It may happen that this requirement contradicts the license +restrictions of other proprietary libraries that do not normally +accompany the operating system. Such a contradiction means you cannot +use both them and the Library together in an executable that you +distribute. + + 7. You may place library facilities that are a work based on the +Library side-by-side in a single library together with other library +facilities not covered by this License, and distribute such a combined +library, provided that the separate distribution of the work based on +the Library and of the other library facilities is otherwise +permitted, and provided that you do these two things: + + a) Accompany the combined library with a copy of the same work + based on the Library, uncombined with any other library + facilities. This must be distributed under the terms of the + Sections above. + + b) Give prominent notice with the combined library of the fact + that part of it is a work based on the Library, and explaining + where to find the accompanying uncombined form of the same work. + + 8. You may not copy, modify, sublicense, link with, or distribute +the Library except as expressly provided under this License. Any +attempt otherwise to copy, modify, sublicense, link with, or +distribute the Library is void, and will automatically terminate your +rights under this License. However, parties who have received copies, +or rights, from you under this License will not have their licenses +terminated so long as such parties remain in full compliance. + + 9. You are not required to accept this License, since you have not +signed it. However, nothing else grants you permission to modify or +distribute the Library or its derivative works. These actions are +prohibited by law if you do not accept this License. Therefore, by +modifying or distributing the Library (or any work based on the +Library), you indicate your acceptance of this License to do so, and +all its terms and conditions for copying, distributing or modifying +the Library or works based on it. + + 10. Each time you redistribute the Library (or any work based on the +Library), the recipient automatically receives a license from the +original licensor to copy, distribute, link with or modify the Library +subject to these terms and conditions. You may not impose any further +restrictions on the recipients' exercise of the rights granted herein. +You are not responsible for enforcing compliance by third parties to +this License. + + 11. If, as a consequence of a court judgment or allegation of patent +infringement or for any other reason (not limited to patent issues), +conditions are imposed on you (whether by court order, agreement or +otherwise) that contradict the conditions of this License, they do not +excuse you from the conditions of this License. If you cannot +distribute so as to satisfy simultaneously your obligations under this +License and any other pertinent obligations, then as a consequence you +may not distribute the Library at all. For example, if a patent +license would not permit royalty-free redistribution of the Library by +all those who receive copies directly or indirectly through you, then +the only way you could satisfy both it and this License would be to +refrain entirely from distribution of the Library. + +If any portion of this section is held invalid or unenforceable under any +particular circumstance, the balance of the section is intended to apply, +and the section as a whole is intended to apply in other circumstances. + +It is not the purpose of this section to induce you to infringe any +patents or other property right claims or to contest validity of any +such claims; this section has the sole purpose of protecting the +integrity of the free software distribution system which is +implemented by public license practices. Many people have made +generous contributions to the wide range of software distributed +through that system in reliance on consistent application of that +system; it is up to the author/donor to decide if he or she is willing +to distribute software through any other system and a licensee cannot +impose that choice. + +This section is intended to make thoroughly clear what is believed to +be a consequence of the rest of this License. + + 12. If the distribution and/or use of the Library is restricted in +certain countries either by patents or by copyrighted interfaces, the +original copyright holder who places the Library under this License may add +an explicit geographical distribution limitation excluding those countries, +so that distribution is permitted only in or among countries not thus +excluded. In such case, this License incorporates the limitation as if +written in the body of this License. + + 13. The Free Software Foundation may publish revised and/or new +versions of the Library General Public License from time to time. +Such new versions will be similar in spirit to the present version, +but may differ in detail to address new problems or concerns. + +Each version is given a distinguishing version number. If the Library +specifies a version number of this License which applies to it and +"any later version", you have the option of following the terms and +conditions either of that version or of any later version published by +the Free Software Foundation. If the Library does not specify a +license version number, you may choose any version ever published by +the Free Software Foundation. + + 14. If you wish to incorporate parts of the Library into other free +programs whose distribution conditions are incompatible with these, +write to the author to ask for permission. For software which is +copyrighted by the Free Software Foundation, write to the Free +Software Foundation; we sometimes make exceptions for this. Our +decision will be guided by the two goals of preserving the free status +of all derivatives of our free software and of promoting the sharing +and reuse of software generally. + + NO WARRANTY + + 15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO +WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW. +EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR +OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY +KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE +IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +PURPOSE. THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE +LIBRARY IS WITH YOU. SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME +THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION. + + 16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN +WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY +AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU +FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR +CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE +LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING +RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A +FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF +SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH +DAMAGES. + + END OF TERMS AND CONDITIONS + + Appendix: How to Apply These Terms to Your New Libraries + + If you develop a new library, and you want it to be of the greatest +possible use to the public, we recommend making it free software that +everyone can redistribute and change. You can do so by permitting +redistribution under these terms (or, alternatively, under the terms of the +ordinary General Public License). + + To apply these terms, attach the following notices to the library. It is +safest to attach them to the start of each source file to most effectively +convey the exclusion of warranty; and each file should have at least the +"copyright" line and a pointer to where the full notice is found. + + + Copyright (C) + + This library is free software; you can redistribute it and/or + modify it under the terms of the GNU Library General Public + License as published by the Free Software Foundation; either + version 2 of the License, or (at your option) any later version. + + This library is distributed in the hope that it will be useful, + but WITHOUT ANY WARRANTY; without even the implied warranty of + MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.

NV_texture_shader adds signed texture formats, + but also a lot of functionality which has been superceded by fragment + shaders. + It is usually possible to get the same functionality + using a unsigned format by doing scale and bias in a shader, but this + is undesirable since modern hardware has direct support for this. + This extension adds a signed 4-channel texture format by backporting + the relevant features from OpenGL 3.1, as a means to support this in + OpenGL implementations only supporting older versions. + +Issues + + 1) What should this extension be called? + + RESOLVED: MESA_texture_signed_rgba seems reasonable. + The rgba part is there because only 4 channel format is supported. + + + 2) Should the full set of signed formats (alpha, luminance, rgb, etc.) + be supported? + + RESOLVED: NO. To keep this extension simple, only add the most + universal format, rgba. alpha/luminance can't be trivially supported + since OpenGL 3.1 does not support them any longer, and there is some + implied dependency on ARB_texture_rg for red/red_green formats so + avoid all this. Likewise, only 8 bits per channel is supported. + + + 3) Should this extension use new enums for the texture formats? + + RESOLVED: NO. Same enums as those used in OpenGL 3.1. + + + 4) How are signed integer values mapped to floating-point values? + + RESOLVED: Same as described in issue 5) of + ARB_texture_compression_rgtc (quote): + A signed 8-bit two's complement value X is computed to + a floating-point value Xf with the formula: + + { X / 127.0, X > -128 + Xf = { + { -1.0, X == -128 + + This conversion means -1, 0, and +1 are all exactly representable, + however -128 and -127 both map to -1.0. Mapping -128 to -1.0 + avoids the numerical awkwardness of have a representable value + slightly more negative than -1.0. + + This conversion is intentionally NOT the "byte" conversion listed + in Table 2.9 for component conversions. That conversion says: + + Xf = (2*X + 1) / 255.0 + + The Table 2.9 conversion is incapable of exactly representing + zero. + + (Difference to ARB_texture_compression_rgtc): + This is the same mapping as OpenGL 3.1 uses. + This is also different to what NV_texture_shader used. + The above mapping should be considered the reference, but there + is some leeway so other mappings are allowed for implementations which + cannot do this. Particulary the mapping given in NV_texture_shader or + the standard OpenGL byte/float mapping is considered acceptable too, as + might be a mapping which represents -1.0 by -128, 0.0 by 0 and 1.0 by + 127 (that is, uses different scale factors for negative and positive + numbers). + Also, it is ok to store incoming GL_BYTE user data as-is, without + converting to GL_FLOAT (using the standard OpenGL float/byte mapping) + and converting back (using the mapping described here). + Other than those subtle issues there are no other non-standard + conversions used, so when using for instance CopyTexImage2D with + a framebuffer clamped to [0,1] all converted numbers will be in the range + [0, 127] (and not scaled and biased). + + + 5) How will signed components resulting from RGBA8_SNORM texture + fetches interact with fragment coloring? + + RESOLVED: Same as described in issue 6) of + ARB_texture_compression_rgtc (quote): + The specification language for this extension is silent + about clamping behavior leaving this to the core specification + and other extensions. The clamping or lack of clamping is left + to the core specification and other extensions. + + For assembly program extensions supporting texture fetches + (ARB_fragment_program, NV_fragment_program, NV_vertex_program3, + etc.) or the OpenGL Shading Language, these signed formats will + appear as expected with unclamped signed components as a result + of a texture fetch instruction. + + If ARB_color_buffer_float is supported, its clamping controls + will apply. + + NV_texture_shader extension, if supported, adds support for + fixed-point textures with signed components and relaxed the + fixed-function texture environment clamping appropriately. If the + NV_texture_shader extension is supported, its specified behavior + for the texture environment applies where intermediate values + are clamped to [-1,1] unless stated otherwise as in the case + of explicitly clamped to [0,1] for GL_COMBINE. or clamping the + linear interpolation weight to [0,1] for GL_DECAL and GL_BLEND. + + Otherwise, the conventional core texture environment clamps + incoming, intermediate, and output color components to [0,1]. + + This implies that the conventional texture environment + functionality of unextended OpenGL 1.5 or OpenGL 2.0 without + using GLSL (and with none of the extensions referred to above) + is unable to make proper use of the signed texture formats added + by this extension because the conventional texture environment + requires texture source colors to be clamped to [0,1]. Texture + filtering of these signed formats would be still signed, but + negative values generated post-filtering would be clamped to + zero by the core texture environment functionality. The + expectation is clearly that this extension would be co-implemented + with one of the previously referred to extensions or used with + GLSL for the new signed formats to be useful. + + + 6) Should the RGBA_SNORM tokens also be accepted by CopyTexImage + functions? + + RESOLVED: YES. + + + 7) What to do with GetTexParameter if ARB_texture_float is supported, + in particular what datatype should this return for TEXTURE_RED_TYPE_ARB, + TEXTURE_GREEN_TYPE_ARB, TEXTURE_BLUE_TYPE_ARB, TEXTURE_ALPHA_TYPE_ARB? + + RESOLVED: ARB_texture_float states type is either NONE, + UNSIGNED_NORMALIZED_ARB, or FLOAT.

1. Introduction

+

The Mini GLX interface facilitates OpenGL rendering on embedded +devices. The interface is a subset of the GLX interface, plus a minimal +set of Xlib-like functions.

+

Programs written to the Mini GLX specification should run unchanged +on systems with the X Window System and the GLX extension. The intention +is to allow flexibility for prototyping and testing.

+

This document serves as both the reference guide and programming +guide for Mini GLX.
+
+

+

2. Mini GLX Concepts

+

The OpenGL specification does not describe how OpenGL rendering +contexts and drawing surfaces (i.e. the frame buffer) are created and +managed. Rather, this is handled by an OpenGL window system interface, +such as Mini GLX.

+

There are three main datatypes or resources managed by Mini GLX. The +resources and their corresponding GLX or Xlib data types are:

+ + + + + + + + + + + + + + + + + + + +
ResourceData type
pixel formatsX Visual and XVisualInfo
drawing surfacesX Window or GLXDrawable
rendering contextsGLXContext
+

Pixel formats or X Visuals describe the per-pixel attributes of the +frame buffer. For example, bits per color component, Z buffer size, +stencil size, TrueColor vs PseudoColor, etc.

+

Drawing surfaces or X Windows typically describe a spatial +allocation of the frame buffer (i.e. the position and size of a +rectangular region of pixels). Since MiniGLX doesn't really support a +window system, the window is effectively the entire frame buffer.

+

A rendering context represents the current OpenGL state such as +current drawing color, line width, blending mode, texture parameters, +etc. Several rendering contexts can be created but only one can be in +use at any given time.

+

The Mini GLX interface provides all the functions needed for +choosing pixel formats, create drawing surfaces, creating rendering +contexts and binding rendering contexts to drawing surfaces.
+
+

+

3. Using Mini GLX

+

To use the Mini GLX interface in your application, include the +GL/miniglx.h header file at compile time:

+
#include <GL/miniglx.h>
+
+Applications should link with libGL.so (i.e. gcc +myprogram.o -lGL -o myprogram).  libGL.so implements the +MiniGLX API functions and, in turn, loads a hardware-specific device +driver (such as radeon_dri.so) at runtime.  The +environment variable LIBGL_DRIVERS_PATH should name the +directory where these modules are located.
+
+The remainder of this section describes the MiniGLX API functions.
+
+

3.1 Initialization

+

The XOpenDisplay function is used to initialize the graphics system:

+
+ 
Display *XOpenDisplay(const char *displayname)
+
+

The displayName parameter is currently ignored in Mini +GLX. It is recommended that NULL be passed as thedisplayName +parameter.

+

If XOpenDisplay is able to initialize the graphics system a pointer +to a Display will be returned. Otherwise, NULL will be returned.

+

3.2 Choosing a Visual

+

A visual (i.e. pixel format) must be chosen before a drawing surface +or rendering context can be created. This is done with the +glXChooseVisual function:

+
+ 
XVisualInfo *glXChooseVisual(Display *dpy, int screen, const int *attribList)
+
+

dpy is a pointer to the display returned by +XOpenDisplay.

+

screen is currently ignored by Mini GLX and should be +zero.

+

attribList is a list of GLX attributes which describe +the desired pixel format. It is terminated by the token None. +The attributes are as follows:

+
+
+
GLX_USE_GL
+
This attribute should always be present in order to maintain +compatibility with GLX.
+
GLX_RGBA
+
If present, only RGBA pixel formats will be considered. +Otherwise, only color index formats are considered.
+
GLX_DOUBLEBUFFER
+
if present, only double-buffered pixel formats will be chosen.
+
GLX_RED_SIZE n
+
Must be followed by a non-negative integer indicating the +minimum number of bits per red pixel component that is acceptable.
+
GLX_GREEN_SIZE n
+
Must be followed by a non-negative integer indicating the +minimum number of bits per green pixel component that is acceptable.
+
GLX_BLUE_SIZE n
+
Must be followed by a non-negative integer indicating the +minimum number of bits per blue pixel component that is acceptable.
+
GLX_ALPHA_SIZE n
+
Must be followed by a non-negative integer indicating the +minimum number of bits per alpha pixel component that is acceptable.
+
GLX_STENCIL_SIZE n
+
Must be followed by a non-negative integer indicating the +minimum number of bits per stencil value that is acceptable.
+
None
+
This token is used to terminate the attribute list.
+
+
+

glXChooseVisual will return a pointer to an XVisualInfo object which +most closely matches the requirements of the attribute list. If there +is no visual which matches the request, NULL will be returned.

+

Note that visuals with accumulation buffers and depth buffers are +not available.
+
+

+

3.3 Creating a Drawing Surface

+

Drawing surfaces are created as X windows.  For Mini GLX, +windows are full-screen; they cover the entire frame buffer. + Also, Mini GLX imposes a limit of one window. A second window +cannot be created until the first one is destroyed.

+

3.3.1 Window Creation

+

The XCreateWindow function is used to create a drawing surface:

+
+ 
Window XCreateWindow( Display *display,
                      Window parent,
                      int x, int y,
                      unsigned int width, unsigned int height,
                      unsigned int borderWidth,
                      int depth,
                      unsigned int class,
                      Visual *visual,
                      unsigned long valuemask,
                      XSetWindowAttributes *attributes )
+
+

The parameters are as follows:

+
+
+
display
+
A Display pointer, as returned by XOpenDisplay.
+
parent
+
The parent window for the new window. For Mini GLX, this +should beRootWindow(dpy, 0).
+
x, y
+
The position of the window. For Mini GLX, both values should +be zero.
+
width, height
+
The size of the window. For Mini GLX, this specifies the +desired screen size such as 1024, 768 or 1280, 1024.
+
borderWidth
+
This parameter should be zero.
+
depth
+
The pixel depth for the window. For Mini GLX this should be +the depth found in the XVisualInfo object returned by glxChooseVisual.
+
class
+
The window class. For Mini GLX this value should be InputOutput.
+
visual
+
This parameter should be the visual field of the XVisualInfo +object returned by glxChooseVisual.
+
valuemask
+
This parameter indicates which fields of the XSetWindowAttributes +are to be used. For Mini GLX this is typically the bitmaskCWBackPixel +| CWBorderPixel | CWColormap.
+
attributes
+
Initial window attributes. Of the fields in the XSetWindowAttributes +structure, thebackground_pixel, border_pixel +and colormap fields should be set.  See the discussion +below regarding colormaps.
+
+
+

XCreateWindow will return a window handle if it succeeds +or zero if it fails.

+

3.3.2 Window Mapping

+

To display the window the XMapWindow function must be called:

+
+ 
void XMapWindow(Display *dpy, Window w)
+
+

This function does nothing in Mini GLX but is required for Xlib/GLX +compatibility

+

3.3.3 Colormaps
+

+

Xlib requires specification of a colormap when creating a window. + For purposes of interoperability, Mini GLX requires this as well, +though the colormap is not actually used.  The XCreateColormap +function is used to create a colormap:

+
Colormap XCreateColormap(Display *dpy, Window window, +Visual *visual, int alloc)
+
+

The parameters are as follows:
+

+
+
+
dpy
+
The display handle as returned by XOpenDisplay.
+
window
+
This parameter is ignored by Mini GLX but should be the value +returned by the RootWindow(dpy, 0) macro.
+
+
visual
+
This parameter is ignored by Mini GLX but should be the visual +field of the XVisualInfo object returned by glXChooseVisual.
+
alloc
+
This parameter is ignored by Mini GLX but should be set to AllocNone.
+
+
+
+

3.4 Creating a Rendering Context

+

An OpenGL rendering context is created with the glXCreateContext +function:

+
+ 
GLXContext glXCreateContext(Display *dpy, XVisualInfo *visInfo, GLXContext shareList, Bool direct)
+
+

The parameters are as follows:

+
+
+
dpy
+
The display handle as returned by XOpenDisplay.
+
visInfo
+
The visual as returned by glXChooseVisual.
+
shareList
+
If non-zero, texture objects and display lists are shared with +the named rendering context. If zero, texture objects and display lists +will (initially) be private to this context. They may be shared when a +subsequent context is created.
+
direct
+
Specifies whether direct or indirect rendering is desired. For +Mini GLX this value is ignored but it should be set to True.
+
+
+

glXCreateContext will return a GLXContext handle if it +succeeds or zero if it fails due to invalid parameter or insufficient +resources.
+
+

+

3.5 Binding a Rendering Context

+

The final step before beginning OpenGL rendering is to bind (i.e. +activate) a rendering context and drawing surface with the +glXMakeCurrent function:

+
+ 
Bool glXMakeCurrent(Display *dpy, GLXDrawable drawable, GLXContext ctx)
+
+

The parameters are as follows:

+
+
+
dpy
+
The display handle, as returned by XOpenDisplay.
+
drawable
+
The window or drawable to bind to the rendering context. This +should be the value returned by XCreateWindow.
+
ctx
+
The rendering context to bind, as returned by glXCreateContext.
+
+
+

If glXMakeCurrent succeeds True is returned. Otherwise False is +returned to indicate an invalid display, window or context parameter.

+

After the rendering context has been bound to the drawing surface +OpenGL rendering can begin.

+

The current rendering context may be unbound by calling +glXMakeCurrent with the window and context parameters set to zero.

+

An application may create any number of rendering contexts and bind +them as needed. Note that binding a rendering context is generally not a +light-weight operation.  Most simple OpenGL applications create +only one rendering context.
+
+

+

3.6 Color Buffer Swapping

+

A double buffered window has two color buffers: a front buffer and a +back buffer. Normally, rendering is directed to the back buffer while +the front buffer is displayed. When rendering of a frame is finished +the front and back buffers are swapped to provide the illusion of +instanteous screen updates.

+

The color buffers for a particular window (i.e. drawable) may be +swapped with the glXSwapBuffers command:

+
+ 
void glXSwapBuffers(Display *dpy, GLXDrawable drawable)
+
+Any pending rendering commands will be completed before the buffer swap +takes place.
+
+Calling glXSwapBuffers on a window which is single-buffered has no +effect.
+
+

3.7 Releasing Resources

+

3.7.1 Releasing Rendering Contexts

+

A rendering context may be destroyed by calling glXDestroyContext:

+
+ 
void glXDestroyContext(Display *dpy, GLXContext ctx)
+
+

3.7.2 Releasing Windows

+

A window may be destroyed by calling XDestroyWindow:

+
+ 
void XDestroyWindow(Display *dpy, Window window)
+
+

3.7.3 Releasing Visuals

+

An XVisualInfo object may be freed by calling XFree:

+
+ 
void XFree(void *data)
+
+

3.7.4 Releasing Colormaps

+

A colormap may be freed by calling XFreeColormap:

+
+ 
void XFreeColormap(Display *dpy, Colormap colormap)
+
+

3.7.4 Releasing Display Resources

+

When the application is about to exit, the resources associated with +the graphics system can be released by calling XCloseDisplay:

+
+ 
void XCloseDisplay(Display *dpy)
+
+

The display handle becomes invalid at this point.
+
+

+

3.8 Query Functions

+

3.8.1 Querying Available Visuals

+A list of all available visuals can be obtained with the XGetVisualInfo +function:
+
+
XVisualInfo +*XGetVisualInfo(Display *dpy, long vinfo_mask, XVisualInfo +*vinfo_template, int *nitems_return)
+
+
+The parameters are as follows:
+
+
+
dpy
+
The display handle, as returned by XOpenDisplay.
+
vinfo_mask
+
A bitmask indicating which fields of the vinfo_template are to +be matched.  The value must be VisualScreenMask.
+
vinfo_template
+
A template whose fields indicate which visual attributes must +be matched by the results.  The screen field of this structure must +be zero.
+
nitems_return
+
Returns the number of visuals returned.
+
+
+The return value is the address of an array of all available visuals.
+
+An example of using XGetVisualInfo to get all available visuals follows:
+
+
XVisualInfo visTemplate, *results;
+int numVisuals;
+Display *dpy = XOpenDisplay(NULL);
+visTemplate.screen = 0;
+results = XGetVisualInfo(dpy, VisualScreenMask, &visTemplate, +&numVisuals);
+
+
+

3.8.2 Querying Visual Attributes

+

The GLX attributes of an X visual may be queried with the +glXGetConfig function:

+
+ 
int glXGetConfig(Display *dpy, XVisualInfo *vis, int attribute, int *value)
+
+

The parameters are as follows:

+
+
+
dpy
+
The display handle, as returned by XOpenDisplay.
+
vis
+
The visual, as returned by glXChooseVisual.
+
attribute
+
The attribute to query. The attributes are listed below.
+
value
+
Pointer to an integer in which the result of the query will be +stored.
+
+
+

The return value will be zero if no error occurs. + GLX_INVALID_ATTRIBUTE will be returned if the attribute +parameter is invalid.  GLX_BAD_VISUAL will be returned +if the XVisualInfo parameter is invalid.

+

The following attributes may be queried:

+
+
+
GLX_USE_GL
+
The result will be True or False to +indicate if OpenGL rendering is supported with the visual. Mini GLX +always return True.
+
GLX_RGBA
+
The result will be True for RGBA visuals or False +for color index visuals.
+
GLX_DOUBLEBUFFER
+
The result will be True if the visual has two +color buffers or False if the visual has one color buffer.
+
GLX_RED_SIZE
+
The result will be the number of red bits per pixel.
+
GLX_GREEN_SIZE
+
The result will be the number of green bits per pixel.
+
GLX_BLUE_SIZE
+
The result will be the number of blue bits per pixel.
+
GLX_ALPHA_SIZE
+
The result will be the number of alpha bits per pixel.
+
GLX_DEPTH_SIZE
+
The result will be the number of bits per Z value.
+
GLX_STENCIL_SIZE
+
The result will be the number of bits per stencil value.
+
+
+
+
+

3.8.3 Querying the Current Rendering Context

+

The current rendering context can be queried with +glXGetCurrentContext:

+
+ 
GLXContext glXGetCurrentContext(void)
+
+

Zero will be returned if no context is currently bound.
+
+

+

3.8.4 Querying the Current Drawable

+

The current drawable (i.e. window or drawing surface) can be queried +with glXGetCurrentDrawable:

+
+ 
GLXDrawable glXGetCurrentDrawable(void)
+
+

Zero will be returned if no drawable is currently bound.
+
+

+

3.8.5 Function Address Queries

+

The glXGetProcAddress function will return the address of any +available OpenGL or Mini GLX function:

+
+ 
void *glXGetProcAddress(const GLubyte *procName)
+
+

If procName is a valid function name, a pointer to that +function will be returned.  Otherwise, NULL will be returned.

+

The purpose of glXGetProcAddress is to facilitate using future +extensions to OpenGL or Mini GLX. If a future version of the library +adds new extension functions they'll be accessible via +glXGetProcAddress. The alternative is to hard-code calls to the new +functions in the application but doing so will prevent linking the +application with older versions of the library.
+
+

+

3.9 Versioning

+The Mini GLX version can be queried at run time with glXQueryVersion: +
+ 
Bool glXQueryVersion(Display *dpy, int *major, int *minor)
+
+

major will be set to the major version number andminor +will be set to the minor version number.True will be +returned if the function succeeds. False will be returned +if the function fails due to invalid parameters. The dpy +argument is currently ignored, but should be the value returned by +XOpenDisplay.

+

At compile time, the Mini GLX interface version can be tested with +the MINI_GLX_VERSION_1_x preprocessor tokens. For example, if +version 1.0 of Mini GLX is supported, then MINI_GLX_VERSION_1_0 +will be defined. If version 1.1 of Mini GLX is supported, then +MINI_GLX_VERSION_1_1 will be defined.

+

At the time of writing the current Mini GLX version is 1.0.
+
+

+

4.0 Interoperability with GLX and Xlib

+While Mini GLX strives to be compatible with GLX and Xlib there are +some unavoidable differences which must be taken into consideration.
+

4.1 Public vs Private Structures

+The structure of many X data types is public.  For example, the Display +data type is defined as a structure in /usr/include/X11/Xlib.h and +programmers may access any fields of that structure at will.  Mini +GLX also defines a Display data type but its fields are hidden and not +visiblein miniglx.h.  Duplicating the Xlib +declaration for the Display data type in minigl.h would +require defining a large number of other superfluous Xlib datatypes.
+
+Mini GLX users are discouraged from directly accessing the fields of +Xlib data types to maximize portability - though this is unavoidable to +some extent.  For example, the XVisualInfo and XSetWindowAtttributes +data types must be completely public. +

4.2 Macros

+In some cases, Xlib defines macros which are meant to be used instead +of direct structure accesses.  For example, the RootWindow(dpy, +screen) macro returns the root window for a given screen on a +given display.  Unfortunately, macros do nothing to aid in ABI +compatibility since they are resolved at compile time instead of at +link/run time.
+
+Mini GLX also defines a RootWindow macro since it's +essential for creating windows.  But the implementation of this +macro by Xlib and Mini GLX is completely different.
+

4.3 Summary

+Because Xlib and Mini GLX define data types and macros differently, +Mini GLX applications must be recompiled when retargeting Mini GLX or +native Xlib/GLX.  That is, applications can't simply be re-linked +because of ABI incompatibilities.
+
+Nevertheless, the fact that Mini GLX programs can be recompiled for +Xlib and GLX increases portability and flexibility for testing and +prototyping.
+
+

5.0 Example Program

+

This section shows an example program which uses the Mini GLX +interface. The program simply draws several frames of a rotating square.
+

+

The program may be compiled for use with Xlib/GLX or Mini GLX by +setting the USE_MINIGLX token to 0 or 1, respectively. + Note that the only difference is the header files which are +included.
+

+

+

#define USE_MINIGLX 1  /* 1 = use Mini GLX, 0 = use Xlib/GLX */

#include <stdio.h>
#include <stdlib.h>
#include <GL/gl.h>

#if USE_MINIGLX
#include <GL/miniglx.h>
#else
#include <GL/glx.h>
#include <X11/Xlib.h>
#endif

Some of it's out of +date, but some is still valid. + + + +What do you need ? +------------------ + + - A PC with a 3Dfx Voodoo1/2 Graphics or Voodoo Rush based board + (Pure3D, Monster 3D, R3D, Obsidian, Stingray 128/3D, etc.). + The Quantum3D Obsidian3D-2 X-24 requires some special env. setting + under Linux (more information in the "Useful Glide Environment + Variables"); + + - The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine). + The Voodoo2 requires the Glide library 2.51. The Glide 3.1 is not + compatible with the Glide 2.x so it doesn't work with the current + version of the driver; + + - A compiler supported by the Glide library (Micro$oft VC++ (tested), + Watcom (tested), GCC for Linux (tested), etc.); + + - It's nice to have two monitors - one for your normal graphics + card and one for your 3Dfx card. If something goes wrong with + an application using the 3Dfx hardware you can still see your + normal screen in order to recover. + + + +Tested on: +---------- + Windows 95 - David Bucciarelli + Windows NT - Henri Fousse + MS-DOS + Linux - Daryll Strauss, Brian Paul, David Bucciarelli + FreeBSD + BeOS - Duncan Wilcox + MacOS - Fazekas Miklos + + +What is able to do ? +-------------------- + + - It is able accelerate points, lines and polygon with flat + shading, gouraud shading, Z-buffer, texture mapping, blending, fog and + antialiasing (when possible). There is also the support for rendering + in a window with a slow trick for the Voodoo Graphics (available only + for Linux) and at full speed with the Voodoo Rush chipset. + Under Linux is also possible to switch on-the-fly between the fullscreen + and in-window rendering hack. + There is also the support for using more than one Voodoo Graphics in the + some application/PC (you can create one context for each board and use + multiple video outputs for driving monitors, videoprojectors or HMDs). + The driver is able to fallback to pure software rendering when afeature + isn't supported by the Voodoo hardware (however software rendering is + very slow compared to hardware supported rendering) + + + +How to compile: +--------------- + +Linux: +------ + Here are the basic steps for using the 3Dfx hardware with Mesa + on Linux: + + - You'll need the Glide library and headers. Mesa expects: + /usr/local/glide/include/*.h // all the Glide headers + /usr/local/glide/lib/libglide2x.so + + If your Glide libraries and headers are in a different directory + you'll have to modify the Mesa-config and mklib.glide files. + + - Unpack the MesaLib-3.1.tar.gz and MesaDemos-3.1.tar.gz archives; + + - If you're going to use a newer Mesa/Glide driver than v0.27 then + unpack the new driver archive over the Mesa directory. + + - In the Mesa-3.1 directory type "make linux-glide" + + - Compilation _should_ finish without errors; + + - Set your LD_LIBRARY_PATH environment variable so that the + libglide2x.so and Mesa library files can be found. For example: + setenv LD_LIBRARY_PATH "/usr/local/glide/lib:/SOMEDIR/Mesa-3.1/lib" + + - You'll have to run Glide-based programs as root or set the suid + bit on executables; + + - Try a demo: + cd gdemos + su + setenv MESA_GLX_FX f + ./gears (hit ESC to exit) + + - You can find the demos especially designed for the Voodoo driver in + in the Mesa-3.1/3Dfx/demos directory (type "make" in order to compile + everything). + +MacOS: +------ + Check the WEB page at http://valerie.inf.elte.hu/~boga/Mesa.html + +MS Windows: +----------- + + For the MSVC++: + - The glide2x.lib have to be in the default MSVC++ lib directory; + + - The Glide headers have to be in the default MSVC++ include directory; + + - You must have the vcvars32.bat script in your PATH; + + - Go to the directory Mesa-3.1 and run the mesafx.bat; + + - The script will compile everything (Mesa-3.1/lib/OpenGL32.{lib,dll}, + Mesa-3.1/lib/GLU32.{lib,dll}, Mesa-3.1/lib/GLUT32.{lib,dll} and + Voodoo demos); + + - At the end, you will be in the Mesa-3.1/3Dfx/demos directory; + + - Try some demo (fire.exe, teapot.exe, etc.) in order to check if + everything is OK (you can use Alt-Tab or Ctrl-F9 to switch between + the Voodoo screen and the windows desktop); + + - Remember to copy the Mesa OpenGL32.dll, GLU32.dll and GLUT32.dll in the + some directory were you run your Mesa based applications. + + - I think that you can easy change the Makefile.fx files in order + to work with other kind of compilers; + + - To discover how open the 3Dfx screen, read the sources under + the Mesa-3.1/3Dfx/demos directory. You can use the GLUT library or + the Diego Picciani's wgl emulator. + + NOTE: the MSVC++ 5.0 optimizer is really buggy. Also if you install the + SP3, you could have some problem (you can disable optimization in order + solve these kind of problems). + + +Doing more with Mesa & Linux Glide: +----------------------------------- + + The MESA_GLX_FX environment variable can be used to coax most + GLX-based programs into using Glide (and the __GLUT library + is GLX-based__). + + Full-screen 3Dfx rendering: + --------------------------- + + 1. Set the MESA_GLX_FX variable to "fullscreen": + + ksh: + export MESA_GLX_FX = "fullscreen" + csh: + setenv MESA_GLX_FX fullscreen + + 2. As root, run a GLX-based program (any GLUT demo on Linux). + + 3. Be careful: once the 3Dfx screen appears you won't be able + to see the GLUT windows on your X display. This can make using + the mouse tricky! One solution is to hook up your 3Dfx card to + a second monitor. If you can do this then set these env vars + first: + + setenv SST_VGA_PASS 1 + setenv SST_NOSHUTDOWN + + or for the Voodoo2: + + setenv SSTV2_VGA_PASS 1 + setenv SSTV2_NOSHUTDOWN + + Rendering into an X window with the help of the Voodoo hardware: + ---------------------------------------------------------------- + + 1. Start your X server in 16 bpp mode (XFree86: startx -- -bpp 16) + in order to have the best performance and the best visual + quality. However you can use any visual depth supported by X. + + 2. Set the following environment variables: + export MESA_GLX_FX="window" # to enable window rendering + export SST_VGA_PASS=1 # to stop video signal switching + export SST_NOSHUTDOWN=1 # to stop video signal switching + OR + setenv MESA_GLX_FX window + setenv SST_VGA_PASS 1 + setenv SST_NOSHUTDOWN 1 + + (the Voodoo2 requires to use "SSTV2_" instead "SST_"). + + 3. As root, try running a GLX-based program + + How does it work? We use the 3Dfx hardware to do rendering then + copy the image from the 3Dfx frame buffer into an X window when + the SwapBuffers() function is called. The problem with this + idea is it's slow. The image must be copied from the 3Dfx frame + buffer to main memory then copied into the X window (and when the X + visual depth doesn't match the Voodoo framebufffer bit per pixel, it + is required also a pixel format translation). + + NOTE: the in-window rendering feature only works with double-buffering. + + + On the fly switching between in window rendering and full screen rendering + -------------------------------------------------------------------------- + + The Mesa 2.6 has introduced the capability of switching + on-the-fly between the fullscreen/fullspeed rendering and the in-window + hack and vice versa. The on-the-fly switching requires a direct support + by the application but it is really easy to add. You have to start + your X server in 16 bpp mode and to add the following lines to your + application: + + #if defined(FX) && define(XMESA) + #include + + static int fullscreen=1; + #endif + + ... + + /* In the GLUT keyboard event callback */ + + #if defined(FX) && !define(WIN32) + case ' ': + fullscreen=(!fullscreen); + XMesaSetFXmode(fullscreen ? XMESA_FX_FULLSCREEN : XMESA_FX_WINDOW); + break; + #endif + ... + + See the 3Dfx/demos/tunnel.c program + for an example. You have to set the -DXMESA flag in the Makefile's COPTS + to enable it. + + Rendering into an X window with the X11 software driver: + -------------------------------------------------------- + + Set the MESA_GLX_FX variable to "disable" your GLX-based program will use + the X11 software driver (the 3Dfx hardware isn't used at all). + + + +Useful Glide Environment Variables: +----------------------------------- + + - To disable the 3Dfx logo, set the FX_GLIDE_NO_SPLASH variable. + + - To disable video signal switching: + setenv SST_VGA_PASS 1 + setenv SST_NOSHUTDOWN + or for the Voodoo2: + setenv SSTV2_VGA_PASS 1 + setenv SSTV2_NOSHUTDOWN + + - To set the default screen refresh rate: + setenv SST_SCREENREFRESH=75 + + the supported values are 60, 70, 72, 75, 80, 85, 90, 100, 120. + + - To force the Mesa library to swap buffers as fast as possible, + without any vertical blanking synchronization (useful for benchmarks): + setenv FX_GLIDE_SWAPINTERVAL 0 + setenv SST_SWAP_EN_WAIT_ON_VIDSYNC 0 + + - You can slight improve the performances of your Voodoo1 board with + the following env. var.: + setenv SST_FASTMEM 1 + setenv SST_PCIRD 1 + setenv SST_GRXCLK 57 + + (don't use this setting with the Quantum3D 100SB or with any other + SLI configuration: it will hang everything !). + The following setting can be used with the Voodoo2: + setenv SSTV2_FASTMEM_RAS_READS=1 + setenv SSTV2_FASTPCIRD=1 + setenv SSTV2_GRXCLK=95 + + - The Quantum3D Obsidian3D-2 X-24 requires some special env. setting + in order to work under Linux: + + export SSTV2_FT_CLKDEL=5 + export SSTV2_TF0_CLKDEL=7 + export SSTV2_TF1_CLKDEL=7 + export SSTV2_TF2_CLKDEL=7 + export SSTV2_SLIM_VIN_CLKDEL=3 + export SSTV2_SLIM_VOUT_CLKDEL=2 + export SSTV2_SLIS_VIN_CLKDEL=3 + export SSTV2_SLIS_VOUT_CLKDEL=2 + + (Thanks to Phil Ross for this trick). + + + + +The Mesa/Voodoo Environment Variables: +-------------------------------------- + + - Only for Windows/Voodoo Rush users, if you define the + env. var.

When only one TMU is + available the driver fallback to bilinear filter also if you ask + for trilinear filtering. + + - The Voodoo driver support multiple Voodoo Graphics boards in the + some PC. Using this feature, you can write applications that use + multiple monitors, videoprojectors or HMDs for the output. See + Mesa-3.1/3Dfx/demos/tunnel2.c for an example of how setup one + context for each board. + + - The v0.19 introduces a new powerful texture memory manager: the + texture memory is used as a cache of the set of all defined texture + maps. You can now define several MBs of texture maps also with a 2MB + of texture memory (the texture memory manager will do automatically + all the swap out/swap in + texture memory work). The new texture memory manager has also + solved a lot of other bugs/no specs compliance/problems + related to the texture memory usage. + + - Use triangles and quads strip: they are a LOT faster than sparse + triangles and quads. + + - The Voodoo driver supports the GL_EXT_paletted_texture. it works + only with GL_COLOR_INDEX8_EXT, GL_RGBA palettes and the alpha value + is ignored because this is a limitation of the the current Glide + version and of the Voodoo hardware. See Mesa-3.1/3Dfx/demos/paltex.c for + a demo of this extension. + + - The Voodoo driver directly supports 3Dfx Global Palette extension. + It was written for GLQuake and I think that it isn't a good idea + to use this extension for any other purpose (it is a trick). See + Mesa-3.1/3Dfx/demos/glbpaltex.c for a demo of this extension. + + - The Voodoo driver chooses the screen resolution according to the + requested window size. If you open a 640x480 window, you will get + a 640x480 screen resolution, if you open a 800x600 window, you + will get a 800x600 screen resolution, etc. + Most GLUT demos support the '-geometry' option, so you can choose + the screen resolution: 'tunnel -geometry 800x600'. + Clearly, you Voodoo board must have enough framebuffer RAM (otherwise + the window creation will fail). + + - The glGetString(GL_RENDERER) returns more information + about the hardware configuration: "Mesa Glide + CARD/ FB/ + TM/ TMU/" + where: CARD is the card used for the current context, + FB is the number of MB for the framebuffer, + TM is the number of MB for the texture memory, + TMU is the number of TMU.

What is 3Dfx? + +3Dfx Interactive, Inc. is the company which builds the VooDoo 3-D graphics +chipset (and others) used in popular PC cards such as the Diamond Monster 3D +and the Orchid Righteous 3D (more informations at http://www.3dfx.com). + + +2. What is Glide? + +Glide is a "thin" programming interface for the 3Dfx hardware. It was +originally written for Windows/Intel but has been ported to Linux/Intel +by Daryll Strauss. + +3Dfx, Inc. should be applauded for allowing the Linux version of Glide +to be written. + +You can directly program with the Glide library if you wish. You can +obtain Glide from the "Developer" section of the 3Dfx website: www.3dfx.com +There's a Linux/Glide newsgroup at news://news.3dfx.com/3dfx.glide.linux + + +3. What is fxmesa? + +"fxmesa" is the name of the Mesa device driver for the 3Dfx Glide library. +It was written by David Bucciarelli and others. It works on both Linux +and Windows. Basically, it allows you to write and run OpenGL-style programs +on the 3Dfx hardware. + + +4. What is GLQuake? + +Quake is a very popular game from id software, Inc. See www.idsoftware.com +GLQuake is a version of Quake written for OpenGL. There is now a Linux +version of GLQuake with works with the Mesa/3Dfx/Glide combo. + +Here's what you need to run GLQuake on Linux: + PC with 100MHz Pentium or better + a 3Dfx-based card + Mesa 3.1 libraries: libMesaGL.so libMesaGLU.so + Glide 2.4 libraries: libglide2x.so libtexus.so + GLQuake for Linux. + +Also, the windows version of GLQuake works fine with the Mesa OpenGL32.dll, +you have only to copy the Mesa-3.1/lib/OpenGL32.dll in the GLQuake directory +in order to test 'MesaQuake'. + + +5. What is GLUT? + +GLUT is Mark Kilgard's OpenGL Utility Toolkit. It provides an API for +writing portable OpenGL programs with support for multiple windows, pop- +up menus, event handling, etc. + +Check the Mark's home page for more informations (http://reality.sgi.com/mjk_asd). + +Every OpenGL programmer should check out GLUT. + +GLUT on Linux uses GLX. + + +6. What is GLX? + +GLX is the OpenGL extension to the X Window System. I defines both a +programming API (glX*() functions) and a network protocol. Mesa implements +an emulation of GLX on Linux. A real GLX implementation would requires +hooks into the X server. The 3Dfx hardware can be used with GLX-based +programs via the MESA_GLX_FX environment variable. + + +7. Is the Voodoo driver able to use the 4Mb texture memory of +the Pure3D boards ? + +Yes, the Voodoo driver v0.20 includes the support for Voodoo +Graphics boards with more than 2Mb of texture memory. + + +8. Do the Voodoo driver support the Voodoo Rush under Windows ? + +Yes, Diego Picciani has developed the support for the Voodoo +Rush but David Bucciarelli has a Pure3D and a Monster3D and Brian Paul +has a Monster3D, so the new versions of the Mesa/Voodoo sometime are +not tested with the Voodoo Rush. + + +9. Do the Voodoo driver support the Voodoo Rush under Linux ? + +No because the Linux Glide doesn't (yet) support the Voodoo Rush. + + +10. Can I sell my Mesa/Voodoo based software and include +a binary copy of the Mesa in order to make the software +working out of the box ? + +Yes. + + +11. Which is the best make target for compiling the Mesa for +Linux GLQuake ('make linux-glide', 'make linux-386-glide', etc.) ? + +'make linux-386-opt-glide' for Voodoo1 and 'make linux-386-opt-V2-glide' +for Voodoo2 boards because it doesn't include the '-fPIC' +option (4-5% faster). + + +12. Can I use a Mesa compiled with a 'make linux-386-opt-V2-glide' +for my applications/programs/demos ? + +Yes, there is only one constrain: you can't run two Mesa applications +at the some time. This isn't a big issue with the today Voodoo Graphics. + + +Thanks to: +---------- + +Henri Fousse (he has written several parts of the v0.15 and the old GLUT + emulator for Win); + +Diego Picciani (he has developed all the Voodoo Rush support and the wgl + emulator); + +Daryll Strauss (for the Linux Glide and the first Linux support); + +Brian Paul (of course); + +Dave 'Zoid' Kirsch (for the Linux GLQuake and Linux Quake2test/Q2 ports) + +Bernd Kreimeier (for the Linux 3Dfx HOWTO and for pushing companies to offer + a better Linux support) + +3Dfx and Quantum3D (for actively supporting Linux) + +The most update places where find Mesa VooDoo driver related informations are +the Mesa mailing list and my driver WEB page +(http://www-hmw.caribel.pisa.it/fxmesa/index.shtml) + + +David Bucciarelli (davibu@tin.it) + +Humanware s.r.l. +Via XXIV Maggio 62 +Pisa, Italy +Tel./Fax +39-50-554108 +email: info.hmw@plus.it +www: www-hmw.caribel.pisa.it diff --git a/mesalib/docs/README.AMIWIN b/mesalib/docs/README.AMIWIN new file mode 100644 index 000000000..47cf696cc --- /dev/null +++ b/mesalib/docs/README.AMIWIN @@ -0,0 +1,181 @@ +AMIGA AMIWIN PORT of MESA: THE OPENGL SOFTWARE EMULATION +======================================================== +Port by Victor Ng-Thow-Hing (victorng@dgp.toronto.edu) +Original Author (Brian Paul (brianp@ssec.wisc.edu) + +Dec.1 , 1995: Port of release Mesa 1.2.5 + - Modifications made to minimize changes to Mesa distribution. + +Nov.25, 1995: Port of release Mesa 1.2.4 + + +HISTORY +======= +As a 3D graphics progammer, I was increasingly frustrated to see OpenGL +appearing on so many platforms EXCEPT the Amiga. Up to now, the task +of porting OpenGL directly from native Amiga drawing routines seemed like +a daunting task. However, two important events made this port possible. + +First of all, Brian Paul wrote Mesa, the OpenGL software emulator that +can be found on many platforms - except the Amiga and Atari (who cares +about the latter!). This was pretty ironic considering that Mesa was +originally prototyped on an Amiga! The second great event was when +Holger Kruse developed AmiWin, the X11R6 server for the Amiga (definitely +register for this great piece of software) and released a development kit +so one could compile X programs with SAS/C. + +Since Mesa had X routines as its primitive drawing operations, this made +a marriage of Mesa and Amiwin feasible. I copied over the sources from +an ftp site, played with the code, wrote some Smakefiles, and voila, +I had OpenGL programs displaying on my Amiga. + +Although the speed is nothing to be impressed about, this port can be +potentially useful to those who want to quickly test their code in +wireframe or perhaps learn more about programming with the OpenGL API. + +I hope Amiga developers will continue to write excellent software for +their machine, especially more X clients for Amiwin. If you have any +solutions so some of my problems in the porting notes, please send me +some email! + +See you around, +Vic. + +HOW TO CREATE THE LIBRARIES AND SAMPLE CODE +=========================================== + +Just run the shell script mklib.amiwin in the mesa directory. This will +make all the libraries and copy them into the mesa/lib directory. If you +don't want to compile everything, just go to the desired directory and +type smake in that directory. + +Change any of the variables in the smakefiles as necessary. You will REQUIRE +the Amiwin development kit to compile these libraries since you need X11.LIB +and the shareable X libraries. Some examples require the AmiTCP4.0 +net.lib static link library and related header files for unix related +header files and functions like sleep(). + +HOW TO USE THE MESA LIBRARIES +============================= + +Study the Smakefiles in the demos, samples and book directories for the +proper SAS/C options and linkable libraries to use. Basically aux calls +require Mesaaux.LIB, gl calls require MesaGL.LIB, glu calls MesaGLU.LIB, +tk calls Mesatk.LIB. There is a preliminary port of MesaGLUT.LIB toolkit +available in the lib directory with the other Mesa libraries. However, +it seems to cause crashes on some of the sample code. Someone else may want +to attempt a more stable port. + +PORTING NOTES TO AMIWIN +======================= + +My strategy of porting was to leave as much of the code untouched as +possible. I surrounded any amiga specific changes with +#ifdef AMIWIN ... #endif or #ifndef AMIWIN ... #endif preprocessor +symbols. The code was ported on an Amiga 2000, with Fusion 40 accelerator +and a Picasso II graphics card. The SAS/C 6.56 compiler was used, with +the AmiWin 2.16 X development kit. + +All compilations were done for a 68040 CPU with 68882 math coprocessor for +maximum speed. Please edit the smakefile for other compilers. +I wrote smakefiles for the directories I ported. I omitted the Windows +and Widgets directories.

However, if this doesn't suit your needs + you can force Mesa to use any X visual you want (any supported by your + X server that is) by setting the MESA_RGB_VISUAL and MESA_CI_VISUAL + environment variables. When an RGB visual is requested, glXChooseVisual + will first look if the MESA_RGB_VISUAL variable is defined. If so, it + will try to use the specified visual. Similarly, when a color index + visual is requested, glXChooseVisual will look for the MESA_CI_VISUAL + variable. + + The format of accepted values is: + Here are some examples: + + using the C-shell: + % setenv MESA_RGB_VISUAL "TrueColor 8" // 8-bit TrueColor + % setenv MESA_CI_VISUAL "PseudoColor 12" // 12-bit PseudoColor + % setenv MESA_RGB_VISUAL "PseudoColor 8" // 8-bit PseudoColor + + using the KornShell: + $ export MESA_RGB_VISUAL="TrueColor 8" + $ export MESA_CI_VISUAL="PseudoColor 12" + $ export MESA_RGB_VISUAL="PseudoColor 8" + + +Double buffering: + Mesa can use either an X Pixmap or XImage as the backbuffer when in + double buffer mode. Using GLX, the default is to use an XImage. The + MESA_BACK_BUFFER environment variable can override this. The valid + values for MESA_BACK_BUFFER are: Pixmap and XImage (only the first + letter is checked, case doesn't matter). + + A pixmap is faster when drawing simple lines and polygons while an + XImage is faster when Mesa has to do pixel-by-pixel rendering. If you + need depth buffering the XImage will almost surely be faster. Exper- + iment with the MESA_BACK_BUFFER variable to see which is faster for + your application. + + +Colormaps: + When using Mesa directly or with GLX, it's up to the application writer + to create a window with an appropriate colormap. The aux, tk, and GLUT + toolkits try to minimize colormap "flashing" by sharing colormaps when + possible. Specifically, if the visual and depth of the window matches + that of the root window, the root window's colormap will be shared by + the Mesa window. Otherwise, a new, private colormap will be allocated. + + When sharing the root colormap, Mesa may be unable to allocate the colors + it needs, resulting in poor color quality. This can happen when a + large number of colorcells in the root colormap are already allocated. + To prevent colormap sharing in aux, tk and GLUT, define the environment + variable MESA_PRIVATE_CMAP. The value isn't significant. + + +Gamma correction: + To compensate for the nonlinear relationship between pixel values + and displayed intensities, there is a gamma correction feature in + Mesa. Some systems, such as Silicon Graphics, support gamma + correction in hardware (man gamma) so you won't need to use Mesa's + gamma facility. Other systems, however, may need gamma adjustment + to produce images which look correct. If in the past you thought + Mesa's images were too dim, read on. + + Gamma correction is controlled with the MESA_GAMMA environment + variable. Its value is of the form "Gr Gg Gb" or just "G" where + Gr is the red gamma value, Gg is the green gamma value, Gb is the + blue gamma value and G is one gamma value to use for all three + channels. Each value is a positive real number typically in the + range 1.0 to 2.5. The defaults are all 1.0, effectively disabling + gamma correction. Examples using csh: + + % setenv MESA_GAMMA "2.3 2.2 2.4" // separate R,G,B values + % setenv MESA_GAMMA "2.0" // same gamma for R,G,B + + The demos/gamma.c program may help you to determine reasonable gamma + value for your display. With correct gamma values, the color intensities + displayed in the top row (drawn by dithering) should nearly match those + in the bottom row (drawn as grays). + + Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well + on HP displays using the HP-ColorRecovery technology. + + Mesa implements gamma correction with a lookup table which translates + a "linear" pixel value to a gamma-corrected pixel value. There is a + small performance penalty. Gamma correction only works in RGB mode. + Also be aware that pixel values read back from the frame buffer will + not be "un-corrected" so glReadPixels may not return the same data + drawn with glDrawPixels. + + For more information about gamma correction see: + http://www.inforamp.net/~poynton/notes/colour_and_gamma/GammaFAQ.html + + +Overlay Planes + + Overlay planes in the frame buffer are supported by Mesa but require + hardware and X server support. To determine if your X server has + overlay support you can test for the SERVER_OVERLAY_VISUALS property: + + xprop -root | grep SERVER_OVERLAY_VISUALS + + +HPCR glClear(GL_COLOR_BUFFER_BIT) dithering + + If you set the MESA_HPCR_CLEAR environment variable then dithering + will be used when clearing the color buffer. This is only applicable + to HP systems with the HPCR (Color Recovery) system. + + +Extensions +========== + There are three Mesa-specific GLX extensions at this time. + + GLX_MESA_pixmap_colormap + + This extension adds the GLX function: + + GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual, + Pixmap pixmap, Colormap cmap ) + + It is an alternative to the standard glXCreateGLXPixmap() function. + Since Mesa supports RGB rendering into any X visual, not just True- + Color or DirectColor, Mesa needs colormap information to convert RGB + values into pixel values. An X window carries this information but a + pixmap does not. This function associates a colormap to a GLX pixmap. + See the xdemos/glxpixmap.c file for an example of how to use this + extension. + + GLX_MESA_release_buffers + + Mesa associates a set of ancillary (depth, accumulation, stencil and + alpha) buffers with each X window it draws into. These ancillary + buffers are allocated for each X window the first time the X window + is passed to glXMakeCurrent(). Mesa, however, can't detect when an + X window has been destroyed in order to free the ancillary buffers. + + The best it can do is to check for recently destroyed windows whenever + the client calls the glXCreateContext() or glXDestroyContext() + functions. This may not be sufficient in all situations though. + + The GLX_MESA_release_buffers extension allows a client to explicitly + deallocate the ancillary buffers by calling glxReleaseBuffersMESA() + just before an X window is destroyed. For example: + + #ifdef GLX_MESA_release_buffers + glXReleaseBuffersMESA( dpy, window ); + #endif + XDestroyWindow( dpy, window ); + + This extension is new in Mesa 2.0. + + GLX_MESA_copy_sub_buffer + + This extension adds the glXCopySubBufferMESA() function. It works + like glXSwapBuffers() but only copies a sub-region of the window + instead of the whole window. + + This extension is new in Mesa version 2.6 + + + +Summary of X-related environment variables: + MESA_RGB_VISUAL - specifies the X visual and depth for RGB mode (X only) + MESA_CI_VISUAL - specifies the X visual and depth for CI mode (X only) + MESA_BACK_BUFFER - specifies how to implement the back color buffer (X only) + MESA_PRIVATE_CMAP - force aux/tk libraries to use private colormaps (X only) + MESA_GAMMA - gamma correction coefficients (X only) + + +---------------------------------------------------------------------- +README.CYGWIN - lassauge April 2004 - based on README.X11 diff --git a/mesalib/docs/README.D3D b/mesalib/docs/README.D3D new file mode 100644 index 000000000..b41fcb620 --- /dev/null +++ b/mesalib/docs/README.D3D @@ -0,0 +1,124 @@ + + DirectX 6 Driver for Mesa 3.0 + + +This software is distributed under the terms of the GNU Library +General Public License, see the LICENSE file for details. + + + +What do you need ? +------------------ + + - A PC with a DirectX 6 video driver installed. + + - Mesa 3.0 + + - The 3Dfx Glide library 2.3 or later for your OS (the 2.4 works fine). + The Voodoo2 requires the Glide library 2.51.

If you 3D card is the secondary (3dfx) then your out of luck for this + release. + + 2) The driver seems like its not HW accelerated. + + If you have a video card with limited memory then you might want to try and + change your destop resolution to a low setting (640x480x16) so that the 3D part + of the card has more resources. Remeber the driver can't make the card better... + + 3) Nothing works. + + Make sure you have a DirectX '6' driver installed. Check you driver docs for this + info or use the SDK info utilities. + The final 'dll' is named opengl32.dll and is either in the same directory as the + OpenGL program or in your system directory (x:\windows\system or x:\winnt\system32). + Check your destop resolution.

The NUL driver is very much like OSMesa. Everything is + done just the same as VESA/VGA drivers, only it doesn't touch your video + hardware. You can query the actual buffer by issuing: + DMesaGetIntegerv(DMESA_GET_BUFFER_ADDR, &buffer); + and dump it to a file. + + Q) How do I query for a list of available video modes to choose as a visual? + A) This is an ugly hack, for which I'm sure I'll burn in hell. + First, query for a list of modes: + n = DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, NULL); + If `n' is strictly positive, you allocate an array of pointers to a given + struct (which is guaranteed to be extended only - not changed in future): + struct { + int xres, yres; + int bpp; + } **l = malloc(n * sizeof(void *)); + Now pass the newly allocated buffer to fill in: + DMesaGetIntegerv(DMESA_GET_VIDEO_MODES, (GLint *)l); + And collect the info: + for (i = 0; i < n; i++) { + printf("%dx%d:%d\n", l[i]->xres, l[i]->yres, l[i]->bpp); + } + + Q) The GLUT is incomplete. + A) See below. + + + +libGLUT (the toolkit): +~~~~~~~~~~~~~~~~~~~~~~ + +Well, this "skeletal" GLUT implementation was taken from AllegGL project and +heavily changed.

Take this example: you have timer A with a very high rate, and +then you have timer B with very low rate compared to A; now, A ticks OK, but +timer B will probably loose precision! + +As an addition, stdout and stderr are redirected and dumped upon exit.

Requirements: + Mesa 3.0. + An SMP capable machine running Linux 2.x + libpthread installed on your machine. + + +2. What does MITS stand for? + MITS stands for Mesa Internal Threading System. By adding + internal threading to Mesa it should be possible to improve + performance of OpenGL applications on SMP machines. + + +3. Do applications have to be recoded to take advantage of MITS? + No. The threading is internal to Mesa and transparent to + applications. + + +4. Will all applications benefit from the current implementation of MITS? + No. This implementation splits the processing of the vertex buffer + over two threads. There is a certain amount of overhead involved + with the thread synchronization and if there is not enough work + to be done the extra overhead outweighs any speedup from using + dual processors. You will not for example see any speedup when + running Quake because it uses GL_POLYGON and there is only one + polygon for each vertex buffer processed. Test results on a + dual 200 Mhz. Pentium Pro system show that one needs around + 100-200 vertices in the vertex buffer before any there is any + appreciable benefit from the threading. + + +5. Are there any parameters that I can tune to try to improve performance. + Yes. You can try to vary the size of the vertex buffer which is + define in VB_MAX located in the file src/vb.h from your top level + Mesa distribution. The number needs to be a multiple of 12 and + the optimum value will probably depend on the capabilities of + your machine and the particular application you are running. + + +6. Are there any ways I can modify the application to improve its + performance with the MITS? + Yes. Try to use as many vertices between each Begin/End pair + as possbile. This will reduce the thread synchronization + overhead. + + +7. What sort of speedups can I expect? + On some benchmarks performance gains of up to 30% have been + observerd.

On a RH 5.x system, you can NOT build +a libc5 executable or library. Red Hat just doesn't include the right +stuff to do it. + +Since Quake is a libc5 based application, you are in trouble. You need +libc5 libraries. + +What can you do about it? Well there's a package called gcc5 that does +MOST of the right stuff to compile with libc5.

There are still a few tricks to getting +Mesa to compile as a libc5 application. First you have to make sure that +every compile uses gcc5 instead of gcc. Second, in some cases the link +line actually lists -L/usr/lib which breaks gcc5 (because it forces you +to use the glibc version of things) + +If you get all the stuff correctly compiled with gcc5 it should work. +I've run Mesa 3.0B6 and its demos in a window with my Rush on a Red Hat +5.1 system.

The demo +executables are placed in the demos directory, because some of them +rely on data files found there. Also, the Mesa lib DLL's were copied +there by the Mesa lib build process. Therefore, you should be able to +simply run the demo executables from the demo directory. + +If you want to run the demos from the Visual Studio, you may have to +change the startup directory and explicitly state where the executables are. + +You may also build all the demo programs by using a makefile.

So, the VC6 +build process uses custom build steps to compile these files in the +GLU library. + +Two additional configurations are provided, Debug x86 and Release x86 +that activate the shader code compilation by defining SLANG_86. It is +unknown if and how this works. + +VC7 (not actively supported) +--- + +The above-mentioned .cc problem does not exist in this version. + +VC8 +--- + +No notes. + + +General +------- + +After building, you can copy the above DLL files to a place in your +PATH such as $SystemRoot/SYSTEM32. If you don't like putting things +in a system directory, place them in the same directory as the +executable(s). Be careful about accidentially overwriting files of +the same name in the SYSTEM32 directory. + +The DLL files are built so that the external entry points use the +stdcall calling convention. + +Static LIB files are not built.

Apps which need the OSMesa interface should link +with both -lOSMesa and -lGL. This change was made so that stand-alone +Mesa works the same way as XFree86/DRI's libGL. + + + +Device Driver Changes / Core Mesa Changes +----------------------------------------- + +The ctx->Driver.LogicOp() function has been removed. It used to +be called during state update in order to determine if the driver +could do glLogicOp() operations, and if not, set the SWLogicOpEnabled +flag. Drivers should instead examine the LogicOp state themselves +and choose specialized point, line, and triangle functions appropriately, +or fall back to software rendering. The Xlib driver was the only driver +to use this function. And since the Xlib driver no longer draws +points, lines or triangles using Xlib, the LogicOp function isn't needed. + +The ctx->Driver.Dither() function has been removed. Drivers should +detect dither enable/disable via ctx->Driver.Enable() instead. + +The ctx->Driver.IndexMask() and ctx->Driver.ColorMask() functions +are now just called from glIndexMask and glColorMask like the other +GL state-changing functions. They are no longer called from inside +gl_update_state(). Also, they now return void. The change was made +mostly for sake of uniformity. + +The NEW_DRVSTATE[0123] flags have been removed.

The only new features in GLX 1.4 +are support for multisampling and the GLX_ARB_get_proc_address extension. +glXGetProcAddress() is the only new function in GLX 1.4. + + + +Multisample and Texture Compression +----------------------------------- + +The OpenGL 1.3 specification allows the multisample and texture compression +features to essentially be no-ops. For example, if you query for multisample +support you'll find none, but the API functions work. + +Similarly, texture compression is not implemented by any of the software +drivers but you can specify a generic compressed texture format (like +GL_COMPRESSED_RGBA) to glTexImage2D and it'll be accepted. + + + +Device Drivers +-------------- + +Mesa advertises itself as either OpenGL 1.2 or OpenGL 1.3 depending on the +device driver. If the driver enables all the ARB extensions which are part +of OpenGL 1.3 then glGetString(GL_VERSION) will return "1.3".

Frames per second printing + + GLUT now looks for an environment variable called "GLUT_FPS". If it's + set, GLUT will print out a frames/second statistic to stderr when + glutSwapBuffers() is called. By default, frames/second is computed + and displayed once every 5 seconds. You can specify a different + interval (in milliseconds) when you set the env var. For example + 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval + to one second. + + NOTE: the demo or application must call the glutInit() function for + this to work. Otherwise, the env var will be ignored. + + Finally, this feature may not be reliable in multi-window programs. + + +2. glutGetProcAddress() function + + The new function: + + void *glutGetProcAddress(const char *procName) + + is a wrapper for glXGetProcAddressARB() and wglGetProcAddress(). It + lets you dynamically get the address of an OpenGL function at runtime. + The GLUT_API_VERSION has been bumped to 5, but I haven't bumped the + GLUT version number from 3.7 since that's probably Mark Kilgard's role. + + This function should probably also be able to return the address of + GLUT functions themselves, but it doesn't do that yet. + + + +XXX Things To Do Yet XXXX +------------------------- + +isosurf with vertex program exhibits some missing triangles (probably +when recycling the vertex buffer for long prims). + + + +Porting Info +------------ + +If you're porting a DRI or other driver from Mesa 4.0.x to Mesa 4.1 here +are some things to change: + +1. ctx->Texture._ReallyEnabled is obsolete. + + Since there are now 5 texture targets (1D, 2D, 3D, cube and rect) that + left room for only 6 units (6*5 < 32) in this field. + This field is being replaced by ctx->Texture._EnabledUnits which has one + bit per texture unit. If the bit k of _EnabledUnits is set, that means + ctx->Texture.Unit[k]._ReallyEnabled is non-zero. You'll have to look at + ctx->Texture.Unit[k]._ReallyEnabled to learn if the 1D, 2D, 3D, cube or + rect texture is enabled for unit k. + + This also means that the constants TEXTURE1_*, TEXTURE2_*, etc are + obsolete. + + The tokens TEXTURE0_* have been replaced as well (since there's no + significance to the "0" part: + + old token new token + TEXTURE0_1D TEXTURE_1D_BIT + TEXTURE0_2D TEXTURE_2D_BIT + TEXTURE0_3D TEXTURE_3D_BIT + TEXTURE0_CUBE TEXTURE_CUBE_BIT + TEXTURE_RECT_BIT + + These tokens are only used for the ctx->Texture.Unit[i].Enabled and + ctx->Texture.Unit[i]._ReallyEnabled fields. Exactly 0 or 1 bits will + be set in _ReallyEnabled at any time! + + Q: "What's the purpose of Unit[i].Enabled vs Unit[i]._ReallyEnabled?" + A: The user can enable GL_TEXTURE_1D, GL_TEXTURE_2D, etc for any + texure unit all at once (an unusual thing to do). + OpenGL defines priorities that basically say GL_TEXTURE_2D has + higher priority than GL_TEXTURE_1D, etc. Also, just because a + texture target is enabled by the user doesn't mean we'll actually + use that texture! If a texture object is incomplete (missing mip- + map levels, etc) it's as if texturing is disabled for that target. + The _ReallyEnabled field will have a bit set ONLY if the texture + target is enabled and complete. This spares the driver writer from + examining a _lot_ of GL state to determine which texture target is + to be used. + + +2. Tnl tokens changes + + During the implementation of GL_NV_vertex_program some of the vertex + buffer code was changed. Specifically, the VERT_* bits defined in + tnl/t_context.h have been renamed to better match the conventions of + GL_NV_vertex_program. The old names are still present but obsolete. + Drivers should use the newer names. + + For example: VERT_RGBA is now VERT_BIT_COLOR0 and + VERT_SPEC_RGB is now VERT_BIT_COLOR1. + + + +3. Read/Draw Buffer changes + + The business of setting the current read/draw buffers in Mesa 4.0.x + was complicated. It's much simpler now in Mesa 4.1. + + Here are the changes: + + - Renamed ctx->Color.DrawDestMask to ctx->Color._DrawDestMask + - Removed ctx->Color.DriverDrawBuffer + - Removed ctx->Pixel.DriverReadBuffer + - Removed ctx->Color.MultiDrawBuffer + - Removed ctx->Driver.SetDrawBuffer() + - Removed swrast->Driver.SetReadBuffer(). + - Added ctx->Color._DrawDestMask - a bitmask of FRONT/BACK_LEFT/RIGHT_BIT + values to indicate the current draw buffers. + - Added ctx->Pixel._ReadSrcMask to indicate the source for pixel reading. + The value is _one_ of the FRONT/BACK_LEFT/RIGHT_BIT values. + - Added ctx->Driver.DrawBuffer() and ctx->Driver.ReadBuffer(). + These functions exactly correspond to glDrawBuffer and glReadBuffer calls. + Many drivers will set ctx->Driver.DrawBuffer = _swrast_DrawBuffer and + leave ctx->Draw.ReadBuffer NULL. + DRI drivers should implement their own function for ctx->Driver.DrawBuffer + and use it to set the current hardware drawing buffer. You'll probably + also want to check for GL_FRONT_AND_BACK mode and fall back to software. + Call _swrast_DrawBuffer() too, to update the swrast state. + - Added swrast->Driver.SetBuffer(). + This function should be implemented by all device drivers that use swrast. + Mesa will call it to specify the buffer to use for span reading AND + writing and point/line/triangle rendering. + There should be no confusion between current read or draw buffer anymore. + - Added swrast->CurrentBuffer to indicate which color buffer to read/draw. + Will be FRONT_LEFT_BIT, BACK_LEFT_BIT, FRONT_RIGHT_BIT or BACK_RIGHT_BIT. + This value is usually passed to swrast->Driver.SetBuffer(). + + +4. _mesa_create_context() changes. This function now takes a pointer to + a __GLimports object. The __GLimports structure contains function + pointers to system functions like fprintf(), malloc(), etc. + The _mesa_init_default_imports() function can be used to initialize + a __GLimports object. Most device drivers (like the DRI drivers) + should use this. + + +5. In tnl's struct vertex_buffer, the field "ProjectedClipCoords" + has been replaced by "NdcPtr" to better match the OpenGL spec's + terminology. + + +6. Since GL_EXT_stencil_two_side has been implemented, many of the + ctx->Stencil fields are now 2-element arrays. For example, + "GLenum Ref" is now "GLenum Ref[2]" The [0] elements are the front-face + values and the [1] elements are the back-face values. + ctx->Stencil.ActiveFace is 0 or 1 to indicate the current face for + the glStencilOp/Func/Mask() functions. + ctx->Stencil.TestTwoSide controls whether or not 1 or 2-sided stenciling + is enabled. + + +7. Removed ctx->Polygon._OffsetAny. Removed ctx->Polygon.OffsetMRD. + + +8. GLfloat / GLchan changes: + + - Changed ctx->Driver.ClearColor() to take GLfloat[4] instead of GLchan[4]. + ctx->Color.ClearColor is now GLfloat[4] too. + - Changed ctx->Driver.AlphaRef() to take GLfloat instead of GLchan. + - ctx->Color.AlphaRef is now GLfloat. + - texObj->BorderColor is now GLfloat[4]. texObj->_BorderChan is GLchan[4]. + + This is part of an effort to remove all GLchan types from core Mesa so + that someday we can support 8, 16 and 32-bit color channels dynamically + at runtime, instead of at compile-time. + + +9. GLboolean ctx->Tranform.ClipEnabled[MAX_CLIP_PLANES] has been replaced + by GLuint ctx->Transform.ClipPlanesEnabled. The later is a bitfield. + + +10. There's a new matrix_stack type in mtypes.h used for the Modelview, + Projection, Color and Texcoord matrix stacks. + + +11. The ctx->Current.* fields have changed a lot. Now, there's a + ctx->Current.Attrib[] array for all vertex attributes which matches + the NV vertex program conventions. + + +---------------------------------------------------------------------- diff --git a/mesalib/docs/RELNOTES-5.0 b/mesalib/docs/RELNOTES-5.0 new file mode 100644 index 000000000..1b22996d8 --- /dev/null +++ b/mesalib/docs/RELNOTES-5.0 @@ -0,0 +1,84 @@ + + Mesa 5.0 release notes + + November 13, 2002 + + PLEASE READ!!!! + + + +Introduction +------------ + +Mesa uses an even/odd version number scheme like the Linux kernel. +Even-numbered versions (such as 5.0) designate stable releases. +Odd-numbered versions (such as 4.1) designate new developmental releases. + +Mesa 5.0 is basically just a stabilization of Mesa 4.1.

Presently, the debugger code and demo code +is in the same file.

The Mesa developers aren't big fans of +automake/autoconf/libtool and didn't have the time to maintain it. +If someone wants to contribute new automake/autoconf support (and is +willing to maintain it), it may be re-incorporated into Mesa, subject +to some requirements. + +The "old style" makefile system has been updated: + 1. Make-config has been trimmed down to fewer, modern configurations. + 2. Most of the bin/mklib.* scripts have been rolled into a new "mklib" + script that works on all sorts of systems. There are probably some + bugs in it, but it's been tested on Linux, SunOS 5.8 and IRIX 6.5. + Improvements/contributes are greatly appreciated. + 3. The Makefile.X11 files have been cleaned up in various ways + + + +Source File Changes +------------------- + +The mmath.[ch] files are obsolete.

1. Basic Usage

+ +

+The autoconf generated configure script can be used to guess your +platform and change various options for building Mesa. To use the +configure script, type: +

+ +
+    ./configure
+
+ +

+To see a short description of all the options, type ./configure +--help. If you are using a development snapshot and the configure +script does not exist, type ./autogen.sh to generate it +first. If you know the options you want to pass to +configure, you can pass them to autogen.sh. It +will run configure with these options after it is +generated. Once you have run configure and set the options +to your preference, type: +

+ +
+    make
+
+ +

+This will produce libGL.so and several other libraries depending on the +options you have chosen. Later, if you want to rebuild for a different +configuration run make realclean before rebuilding. +

+ +

+Some of the generic autoconf options are used with Mesa: + +

    +
  • --prefix=PREFIX - This is the root directory where +files will be installed by make install. The default is +/usr/local. +
    • +
  • --exec-prefix=EPREFIX - This is the root directory +where architecture-dependent files will be installed. In Mesa, this is +only used to derive the directory for the libraries. The default is +${prefix}. +
    • +
  • --libdir=LIBDIR - This option specifies the directory +where the GL libraries will be installed. The default is +${exec_prefix}/lib. It also serves as the name of the +library staging area in the source tree. For instance, if the option +--libdir=/usr/local/lib64 is used, the libraries will be +created in a lib64 directory at the top of the Mesa source +tree. +
    • +
  • --enable-static, --disable-shared - By default, Mesa +will build shared libraries. Either of these options will force static +libraries to be built. It is not currently possible to build static and +shared libraries in a single pass. +
    • +
  • CC, CFLAGS, CXX, CXXFLAGS - These environment variables +control the C and C++ compilers used during the build. By default, +gcc and g++ are used with the options +"-g -O2". +
    • +
  • LDFLAGS - An environment variable specifying flags to +pass when linking programs. These are normally empty, but can be used +to direct the linker to use libraries in nonstandard directories. For +example, LDFLAGS="-L/usr/X11R6/lib". +
    • +
  • PKG_CONFIG_PATH - When available, the +pkg-config utility is used to search for external libraries +on the system. This environment variable is used to control the search +path for pkg-config. For instance, setting +PKG_CONFIG_PATH=/usr/X11R6/lib/pkgconfig will search for +package metadata in /usr/X11R6 before the standard +directories. +
    • +
+

+ +

+There are also a few general options for altering the Mesa build: +

    +
  • --with-x - When the X11 development libraries are +needed, the pkg-config utility will +be used for locating them. If they cannot be found through +pkg-config a fallback routing using imake will +be used. In this case, the --with-x, +--x-includes and --x-libraries options can +control the use of X for Mesa. +
    • +
  • --enable-gl-osmesa - The OSMesa +library can be built on top of libGL for drivers that provide it. +This option controls whether to build libOSMesa. By default, this is +enabled for the Xlib driver and disabled otherwise. Note that this +option is different than using OSMesa as the driver. +
    • +
  • --enable-debug - This option will enable compiler +options and macros to aid in debugging the Mesa libraries. +
    • +
  • --disable-asm - There are assembly routines +available for a few architectures. These will be used by default if +one of these architectures is detected. This option ensures that +assembly will not be used. +
    • +
  • --enable-32-bit, --enable-64-bit - By default, the +build will compile code as directed by the environment variables +CC, CFLAGS, etc. If the compiler is +gcc, these options offer a helper to add the compiler flags +to force 32- or 64-bit code generation as used on the x86 and x86_64 +architectures. +
    • +
+

+ + + +

2. Driver Options

+ +

+There are several different driver modes that Mesa can use. These are +described in more detail in the basic +installation instructions. The Mesa driver is controlled through the +configure option --with-driver. There are currently three supported +options in the configure script. +

+ + + + + +

3. Library Options

+ +

+The configure script provides more fine grained control over the GL +libraries that will be built. More details on the specific GL libraries +can be found in the basic installation +instructions. + +

+

+ + + +

4. Demo Program Options

+ +

+There are many demonstration programs in the MesaDemos tarball. If the +programs are available when ./configure is run, a subset of +the programs will be built depending on the driver and library options +chosen. See the directory progs for the full set of demos. + +

    +
  • --with-demos=DEMOS,DEMOS,... - This option allows a +specific set of demo programs to be built. For example, +--with-demos="xdemos,slang". Beware that if this option is +used, it will not be ensured that the necessary GL libraries will be +available. +
    • +
  • --without-demos - This completely disables building the +demo programs. It is equivalent to --with-demos=no. +

Bug Database

+ +

+The Mesa bug database is hosted on +freedesktop.org. +The old bug database on SourceForge is no longer used. +

+ +

+To file a Mesa bug, go to + +Bugzilla on freedesktop.org +

+ +

+Please follow these bug reporting guidelines: +

+ +
    +
  • Check if a new version of Mesa is available which might have fixed +the problem. +
  • Check if your bug is already reported in the database. +
  • Monitor your bug report for requests for additional information, etc. +
  • If you're reporting a crash, try to use your debugger (gdb) to get a stack +trace. Also, recompile Mesa in debug mode to get more detailed information. +
  • Describe in detail how to reproduce the bug, especially with games +and applications that the Mesa developers might not be familiar with. +
  • Provide a simple GLUT-based test program if possible +
+ +

+Bug reports will automatically be forwarded by bugzilla to the Mesa +developer's mailing list. +

+ +

+The easier a bug is to reproduce, the sooner it will be fixed. +Please do everything you can to facilitate quickly fixing bugs. +If your bug report is vague or your test program doesn't compile +easily, the problem may not be fixed very quickly. +

Mesa/Gallium Cell Driver

+ +

+The Mesa +Cell +driver is part of the +Gallium3D +architecture. +Tungsten Graphics did the original implementation of the Cell driver. +

+ + +

Source Code

+ +

+The latest Cell driver source code is on the master branch of the Mesa +git repository. +

+

+To build the driver you'll need the IBM Cell SDK (version 2.1 or 3.0). +To use the driver you'll need a Cell system, such as a PS3 running Linux, +or the Cell Simulator (untested, though). +

+ +

+If using Cell SDK 2.1, see the configs/linux-cell file for some +special changes. +

+ +

+To compile the code, run make linux-cell. +Or to build in debug mode, run make linux-cell-debug. +

+ +

+To use the library, make sure your current directory is the top of the +Mesa tree, then set LD_LIBRARY_PATH like this: +

+  export LD_LIBRARY_PATH=$PWD/lib/gallium:$PWD/lib/
+
+ +

+Verify that the Cell driver is being used by running +progs/xdemos/glxinfo and looking for: +

+  OpenGL renderer string: Gallium 0.3, Cell on Xlib
+
+ + +

Driver Implementation Summary

+ +

+Rasterization is parallelized across the SPUs in a tiled-based manner. +Batches of transformed triangles are sent to the SPUs (actually, pulled by from +main memory by the SPUs). +Each SPU loops over a set of 32x32-pixel screen tiles, rendering the triangles +into each tile. +Because of the limited SPU memory, framebuffer tiles are paged in/out of +SPU local store as needed. +Similarly, textures are tiled and brought into local store as needed. +

+ + +

Status

+ +

+As of October 2008, the driver runs quite a few OpenGL demos. +Features that work include: +

+
    +
  • Point/line/triangle rendering, glDrawPixels +
  • 2D, NPOT and cube texture maps with nearest/linear/mipmap filtering +
  • Dynamic SPU code generation for fragment shaders, but not complete +
  • Dynamic SPU code generation for fragment ops (blend, Z-test, etc), but not complete +
  • Dynamic PPU/PPC code generation for vertex shaders, but not complete +
+

+Performance has recently improved with the addition of PPC code generation +for vertex shaders, but the code quality isn't too great yet. +

+

+Another bottleneck is SwapBuffers. It may be the limiting factor for +many simple GL tests. +

+ + + +

Debug Options

+ +

+The CELL_DEBUG env var can be set to a comma-separated list of one or +more of the following debug options: +

+
    +
  • checker - use a different background clear color for each SPU. + This lets you see which SPU is rendering which screen tiles. +
  • sync - wait/synchronize after each DMA transfer +
  • asm - print generated SPU assembly code to stdout +
  • fragops - emit fragment ops debug messages +
  • fragopfallback - don't use codegen for fragment ops +
  • cmd - print SPU commands as their received +
  • cache - print texture cache statistics when program exits +
+

+Note that some of these options may only work for linux-cell-debug builds. +

+ +

+If the GALLIUM_NOPPC env var is set, PPC code generation will not be used +and vertex shaders will be run with the TGSI interpreter. +

+

+If the GALLIUM_NOCELL env var is set, the softpipe driver will be used +intead of the Cell driver. +This is useful for comparison/validation. +

+ + + +

Contributing

Conformance

+ +

+The SGI OpenGL conformance tests verify correct operation of OpenGL +implementations. I, Brian Paul, have been given a copy of the tests +for testing Mesa. The tests are not publically available. +

+

+This file has the latest results of testing Mesa with the OpenGL 1.2 +conformance tests. Testing with the preliminary OpenGL 1.3 tests has +also been done. Mesa passes all the 1.3 tests. +

+

+The tests were run using the software X11 device driver on 24-bpp +and 16-bpp displays. +

+

+Mesa 4.0 and later pass all conformance tests at all path levels. +Note that this says nothing about the conformance of hardware drivers +based upon Mesa. +

Debugging Tips

+ +

+ Normally Mesa (and OpenGL) records but does not notify the user of + errors. It is up to the application to call + glGetError to check for errors. Mesa supports an + environment variable, MESA_DEBUG, to help with debugging. If + MESA_DEBUG is defined, a message will be printed to stdout whenever + an error occurs. +

+ +

+ More extensive error checking is done when Mesa is compiled with the + DEBUG symbol defined. You'll have to edit the Make-config file and + add -DDEBUG to the CFLAGS line for your system configuration. You may + also want to replace any optimization flags with the -g flag so you can + use your debugger. After you've edited Make-config type 'make clean' + before recompiling. +

+

+ In your debugger you can set a breakpoint in _mesa_error() to trap Mesa + errors. +

+

+ There is a display list printing/debugging facility. See the end of + src/dlist.c for details. +

Adding Extentions

+ +

+To add a new GL extension to Mesa you have to do at least the following. + +

    +
  • + If glext.h doesn't define the extension, edit include/GL/gl.h and add + code like this: + 
    +     #ifndef GL_EXT_the_extension_name
+     #define GL_EXT_the_extension_name 1
+     /* declare the new enum tokens */
+     /* prototype the new functions */
+     /* TYPEDEFS for the new functions */
+     #endif
+
    +
    • +
  • + In the src/mesa/glapi/ directory, add the new extension functions and + enums to the gl_API.xml file. + Then, a bunch of source files must be regenerated by executing the + corresponding Python scripts. +
    • +
  • + Add a new entry to the gl_extensions struct in mtypes.h +
    • +
  • + Update the extensions.c file. +
    • +
  • + From this point, the best way to proceed is to find another extension, + similar to the new one, that's already implemented in Mesa and use it + as an example. +
    • +
  • + If the new extension adds new GL state, the functions in get.c, enable.c + and attrib.c will most likely require new code. +
    • +
+ + + +

Coding Style

+ +

+Mesa's code style has changed over the years. Here's the latest. +

+ +

+Comment your code! It's extremely important that open-source code be +well documented. Also, strive to write clean, easily understandable code. +

+ +

+3-space indentation +

+ +

+If you use tabs, set them to 8 columns +

+ +

+Brace example: +

+
+	if (condition) {
+	   foo;
+	}
+	else {
+	   bar;
+	}
+
+ +

+Here's the GNU indent command which will best approximate my preferred style: +

+
+	indent -br -i3 -npcs --no-tabs infile.c -o outfile.c
+
+ + +

+Local variable name example: localVarName (no underscores) +

+ +

+Constants and macros are ALL_UPPERCASE, with _ between words +

+ +

+Global variables are not allowed. +

+ +

+Function name examples: +

+
+	glFooBar()       - a public GL entry point (in dispatch.c)
+	_mesa_FooBar()   - the internal immediate mode function
+	save_FooBar()    - retained mode (display list) function in dlist.c
+	foo_bar()        - a static (private) function
+	_mesa_foo_bar()  - an internal non-static Mesa function
+
+ + +

Making a New Mesa Release

+ +

+These are the instructions for making a new Mesa release. +

+ +

Get latest source files

+

+Use git to get the latest Mesa files from the git repository, from whatever +branch is relevant. +

+ + +

Verify and update version info

+

+Create/edit the docs/relnotes-x.y.html file to document what's new in the release. +Add the new relnotes-x.y.html file to relnotes.html. +

+ +

+Update the MESA_MAJOR, MESA_MINOR and MESA_TINY version numbers in +configs/default. +Also update the VERSION line in the top-level Makefile. +

+ +

+Make sure the values in src/mesa/main/version.h are correct. +

+ +

+Update the docs/news.html file and docs/download.html files. +

+ +

+Check in all updates to git. +

+ +

+Tag the files with the release name (in the form mesa_X_Y) +with: git tag -a mesa_X_Y +Then: git push origin mesa_X_Y +

+ + +

Make the tarballs

+

+Make a symbolic link from $(DIRECTORY) to 'Mesa'. For example, +ln -s Mesa Mesa-7.5 +This is needed in order to make a correct tar file in the next step. +

+ +

+Make the distribution files. From inside the Mesa directory: +

+	make tarballs
+
+ +

+After the tarballs are created, the md5 checksums for the files will +be computed. +Add them to the docs/relnotes-X.Y.html file. +

+ +

+Copy the distribution files to a temporary directory, unpack them, +compile everything, and run some demos to be sure everything works. +

+ +

Update the website and announce the release

+

+Follow the directions on SourceForge for creating a new "release" and +uploading the tarballs. +

+ +

+Basically, to upload the tarball files with: +
+ +rsync -avP ssh Mesa*-X.Y.* USERNAME@frs.sourceforge.net:uploads/ + +

+ +

+Update the web site by copying the docs/ directory's files to +/home/users/b/br/brianp/mesa-www/htdocs/ with: +
+ +sftp USERNAME,mesa3d@web.sourceforge.net + +

+ +

+Make an announcement on the mailing lists: +mesa3d-dev@lists.sf.net, +mesa3d-users@lists.sf.net +and +mesa3d-announce@lists.sf.net +

GL Dispatch in Mesa

+ +

Several factors combine to make efficient dispatch of OpenGL functions +fairly complicated. This document attempts to explain some of the issues +and introduce the reader to Mesa's implementation. Readers already familiar +with the issues around GL dispatch can safely skip ahead to the overview of Mesa's implementation.

+ +

1. Complexity of GL Dispatch

+ +

Every GL application has at least one object called a GL context. +This object, which is an implicit parameter to ever GL function, stores all +of the GL related state for the application. Every texture, every buffer +object, every enable, and much, much more is stored in the context. Since +an application can have more than one context, the context to be used is +selected by a window-system dependent function such as +glXMakeContextCurrent.

+ +

In environments that implement OpenGL with X-Windows using GLX, every GL +function, including the pointers returned by glXGetProcAddress, are +context independent. This means that no matter what context is +currently active, the same glVertex3fv function is used.

+ +

This creates the first bit of dispatch complexity. An application can +have two GL contexts. One context is a direct rendering context where +function calls are routed directly to a driver loaded within the +application's address space. The other context is an indirect rendering +context where function calls are converted to GLX protocol and sent to a +server. The same glVertex3fv has to do the right thing depending +on which context is current.

+ +

Highly optimized drivers or GLX protocol implementations may want to +change the behavior of GL functions depending on current state. For +example, glFogCoordf may operate differently depending on whether +or not fog is enabled.

+ +

In multi-threaded environments, it is possible for each thread to have a +differnt GL context current. This means that poor old glVertex3fv +has to know which GL context is current in the thread where it is being +called.

+ + +

2. Overview of Mesa's Implementation

+ +

Mesa uses two per-thread pointers. The first pointer stores the address +of the context current in the thread, and the second pointer stores the +address of the dispatch table associated with that context. The +dispatch table stores pointers to functions that actually implement +specific GL functions. Each time a new context is made current in a thread, +these pointers a updated.

+ +

The implementation of functions such as glVertex3fv becomes +conceptually simple:

+ +
    +
  • Fetch the current dispatch table pointer.
    • +
  • Fetch the pointer to the real glVertex3fv function from the +table.
    • +
  • Call the real function.
    • +
+ +

This can be implemented in just a few lines of C code. The file +src/mesa/glapi/glapitemp.h contains code very similar to this.

+ +
+ + +
+void glVertex3f(GLfloat x, GLfloat y, GLfloat z)
+{
+    const struct _glapi_table * const dispatch = GET_DISPATCH();
+    
+    (*dispatch->Vertex3f)(x, y, z);
+}
Sample dispatch function
+
+ +

The problem with this simple implementation is the large amount of +overhead that it adds to every GL function call.

+ +

In a multithreaded environment, a niave implementation of +GET_DISPATCH involves a call to pthread_getspecific or a +similar function. Mesa provides a wrapper function called +_glapi_get_dispatch that is used by default.

+ +

3. Optimizations

+ +

A number of optimizations have been made over the years to diminish the +performance hit imposed by GL dispatch. This section describes these +optimizations. The benefits of each optimization and the situations where +each can or cannot be used are listed.

+ +

3.1. Dual dispatch table pointers

+ +

The vast majority of OpenGL applications use the API in a single threaded +manner. That is, the application has only one thread that makes calls into +the GL. In these cases, not only do the calls to +pthread_getspecific hurt performance, but they are completely +unnecessary! It is possible to detect this common case and avoid these +calls.

+ +

Each time a new dispatch table is set, Mesa examines and records the ID +of the executing thread. If the same thread ID is always seen, Mesa knows +that the application is, from OpenGL's point of view, single threaded.

+ +

As long as an application is single threaded, Mesa stores a pointer to +the dispatch table in a global variable called _glapi_Dispatch. +The pointer is also stored in a per-thread location via +pthread_setspecific. When Mesa detects that an application has +become multithreaded, NULL is stored in _glapi_Dispatch.

+ +

Using this simple mechanism the dispatch functions can detect the +multithreaded case by comparing _glapi_Dispatch to NULL. +The resulting implementation of GET_DISPATCH is slightly more +complex, but it avoids the expensive pthread_getspecific call in +the common case.

+ +
+ + +
+#define GET_DISPATCH() \
+    (_glapi_Dispatch != NULL) \
+        ? _glapi_Dispatch : pthread_getspecific(&_glapi_Dispatch_key)
+
Improved GET_DISPATCH Implementation
+
+ +

3.2. ELF TLS

+ +

Starting with the 2.4.20 Linux kernel, each thread is allocated an area +of per-thread, global storage. Variables can be put in this area using some +extensions to GCC. By storing the dispatch table pointer in this area, the +expensive call to pthread_getspecific and the test of +_glapi_Dispatch can be avoided.

+ +

The dispatch table pointer is stored in a new variable called +_glapi_tls_Dispatch. A new variable name is used so that a single +libGL can implement both interfaces. This allows the libGL to operate with +direct rendering drivers that use either interface. Once the pointer is +properly declared, GET_DISPACH becomes a simple variable +reference.

+ +
+ + +
+extern __thread struct _glapi_table *_glapi_tls_Dispatch
+    __attribute__((tls_model("initial-exec")));
+
+#define GET_DISPATCH() _glapi_tls_Dispatch
+
TLS GET_DISPATCH Implementation
+
+ +

Use of this path is controlled by the preprocessor define +GLX_USE_TLS. Any platform capable of using TLS should use this as +the default dispatch method.

+ +

3.3. Assembly Language Dispatch Stubs

+ +

Many platforms has difficulty properly optimizing the tail-call in the +dispatch stubs. Platforms like x86 that pass parameters on the stack seem +to have even more difficulty optimizing these routines. All of the dispatch +routines are very short, and it is trivial to create optimal assembly +language versions. The amount of optimization provided by using assembly +stubs varies from platform to platform and application to application. +However, by using the assembly stubs, many platforms can use an additional +space optimization (see below).

+ +

The biggest hurdle to creating assembly stubs is handling the various +ways that the dispatch table pointer can be accessed. There are four +different methods that can be used:

+ +
    +
  1. Using _glapi_Dispatch directly in builds for non-multithreaded +environments.
    2. +
  2. Using _glapi_Dispatch and _glapi_get_dispatch in +multithreaded environments.
    3. +
  3. Using _glapi_Dispatch and pthread_getspecific in +multithreaded environments.
    4. +
  4. Using _glapi_tls_Dispatch directly in TLS enabled +multithreaded environments.
    5. +
+ +

People wishing to implement assembly stubs for new platforms should focus +on #4 if the new platform supports TLS. Otherwise, implement #2 followed by +#3. Environments that do not support multithreading are uncommon and not +terribly relevant.

+ +

Selection of the dispatch table pointer access method is controlled by a +few preprocessor defines.

+ +
    +
  • If GLX_USE_TLS is defined, method #4 is used.
    • +
  • If PTHREADS is defined, method #3 is used.
    • +
  • If any of PTHREADS, +SOLARIS_THREADS, WIN32_THREADS, or BEOS_THREADS +is defined, method #2 is used.
    • +
  • If none of the preceeding are defined, method #1 is used.
    • +
+ +

Two different techniques are used to handle the various different cases. +On x86 and SPARC, a macro called GL_STUB is used. In the preamble +of the assembly source file different implementations of the macro are +selected based on the defined preprocessor variables. The assmebly code +then consists of a series of invocations of the macros such as: + +

+ + +
+GL_STUB(Color3fv, _gloffset_Color3fv)
+
SPARC Assembly Implementation of glColor3fv
+
+ +

The benefit of this technique is that changes to the calling pattern +(i.e., addition of a new dispatch table pointer access method) require fewer +changed lines in the assembly code.

+ +

However, this technique can only be used on platforms where the function +implementation does not change based on the parameters passed to the +function. For example, since x86 passes all parameters on the stack, no +additional code is needed to save and restore function parameters around a +call to pthread_getspecific. Since x86-64 passes parameters in +registers, varying amounts of code needs to be inserted around the call to +pthread_getspecific to save and restore the GL function's +parameters.

+ +

The other technique, used by platforms like x86-64 that cannot use the +first technique, is to insert #ifdef within the assembly +implementation of each function. This makes the assembly file considerably +larger (e.g., 29,332 lines for glapi_x86-64.S versus 1,155 lines for +glapi_x86.S) and causes simple changes to the function +implementation to generate many lines of diffs. Since the assmebly files +are typically generated by scripts (see below), this +isn't a significant problem.

+ +

Once a new assembly file is created, it must be inserted in the build +system. There are two steps to this. The file must first be added to +src/mesa/sources. That gets the file built and linked. The second +step is to add the correct #ifdef magic to +src/mesa/main/dispatch.c to prevent the C version of the dispatch +functions from being built.

+ + +

3.4. Fixed-Length Dispatch Stubs

+ +

To implement glXGetProcAddress, Mesa stores a table that +associates function names with pointers to those functions. This table is +stored in src/mesa/glapi/glprocs.h. For different reasons on +different platforms, storing all of those pointers is inefficient. On most +platforms, including all known platforms that support TLS, we can avoid this +added overhead.

+ +

If the assembly stubs are all the same size, the pointer need not be +stored for every function. The location of the function can instead be +calculated by multiplying the size of the dispatch stub by the offset of the +function in the table. This value is then added to the address of the first +dispatch stub.

+ +

This path is activated by adding the correct #ifdef magic to +src/mesa/glapi/glapi.c just before glprocs.h is +included.

+ + +

1. High-level Questions and Answers

+ +

1.1 What is Mesa?

+

+Mesa is an open-source implementation of the OpenGL specification. +OpenGL is a programming library for writing interactive 3D applications. +See the OpenGL website for more +information. +

+

+Mesa 6.x supports the OpenGL 1.5 specification. +

+ + +

1.2 Does Mesa support/use graphics hardware?

+

+Yes. Specifically, Mesa serves as the OpenGL core for the open-source DRI +drivers for XFree86/X.org. See the DRI +website for more information. +

+

+There have been other hardware drivers for Mesa over the years (such as +the 3Dfx Glide/Voodoo driver, an old S3 driver, etc) but the DRI drivers +are the modern ones. +

+ +

1.3 What purpose does Mesa serve today?

+

+Hardware-accelerated OpenGL implementations are available for most popular +operating systems today. +Still, Mesa serves at least these purposes: +

+
    +
  • Mesa is used as the core of the open-source XFree86/X.org DRI + hardware drivers. +
    • +
  • Mesa is quite portable and allows OpenGL to be used on systems + that have no other OpenGL solution. +
    • +
  • Software rendering with Mesa serves as a reference for validating the + hardware drivers. +
    • +
  • A software implementation of OpenGL is useful for experimentation, + such as testing new rendering techniques. +
    • +
  • Mesa can render images with deep color channels: 16-bit integer + and 32-bit floating point color channels are supported. + This capability is only now appearing in hardware. +
    • +
  • Mesa's internal limits (max lights, clip planes, texture size, etc) can be + changed for special needs (hardware limits are hard to overcome). +

1.4 What's the difference between"Stand-Alone" Mesa and the DRI drivers?

+

+Stand-alone Mesa is the original incarnation of Mesa. +On systems running the X Window System it does all its rendering through +the Xlib API: +

    +
  • The GLX API is supported, but it's really just an emulation of the + real thing. +
  • The GLX wire protocol is not supported and there's no OpenGL extension + loaded by the X server. +
  • There is no hardware acceleration. +
  • The OpenGL library, libGL.so, contains everything (the programming API, + the GLX functions and all the rendering code). +
+

+

+Alternately, Mesa acts as the core for a number of OpenGL hardware drivers +within the DRI (Direct Rendering Infrastructure): +

    +
  • The libGL.so library provides the GL and GLX API functions, a GLX + protocol encoder, and a device driver loader. +
  • The device driver modules (such as r200_dri.so) contain a built-in + copy of the core Mesa code. +
  • The X server loads the GLX module. + The GLX module decodes incoming GLX protocol and dispatches the commands + to a rendering module. + For the DRI, this module is basically a software Mesa renderer. +
+ + + +

1.5 How do I upgrade my DRI installation to use a new Mesa release?

+

+This wasn't easy in the past. +Now, the DRI drivers are included in the Mesa tree and can be compiled +separately from the X server. +Just follow the Mesa compilation instructions. +

+ + +

1.6 Are there other open-source implementations of OpenGL?

+

+Yes, SGI's +OpenGL Sample Implemenation (SI) is available. +The SI was written during the time that OpenGL was originally designed. +Unfortunately, development of the SI has stagnated. +Mesa is much more up to date with modern features and extensions. +

+ +

+Vincent is +an open-source implementation of OpenGL ES for mobile devices. + +

+miniGL +is a subset of OpenGL for PalmOS devices. + +

+TinyGL is a subset of OpenGL. +

+ +

+SoftGL +is an OpenGL subset for mobile devices. +

+ +

+Chromium +isn't a conventional OpenGL implementation (it's layered upon OpenGL), +but it does export the OpenGL API. It allows tiled rendering, sort-last +rendering, etc. +

+ +

+ClosedGL is an OpenGL subset library for TI +graphing calculators. +

+ +

+There may be other open OpenGL implementations, but Mesa is the most +popular and feature-complete. +

+ + + +
+
+ + + +

2. Compilation and Installation Problems

+ + +

2.1 What's the easiest way to install Mesa?

+

+If you're using a Linux-based system, your distro CD most likely already +has Mesa packages (like RPM or DEB) which you can easily install. +

+ + +

2.2 I get undefined symbols such as bgnpolygon, v3f, etc...

+

+You're application is written in IRIS GL, not OpenGL. +IRIS GL was the predecessor to OpenGL and is a different thing (almost) +entirely. +Mesa's not the solution. +

+ + +

2.3 Where is the GLUT library?

+

+GLUT (OpenGL Utility Toolkit) is in the separate MesaGLUT-x.y.z.tar.gz file. +If you don't already have GLUT installed, you should grab the MesaGLUT +package and compile it with the rest of Mesa. +

+ + + +

2.4 What's the proper place for the libraries and headers?

+

+On Linux-based systems you'll want to follow the +Linux ABI standard. +Basically you'll want the following: +

+
    +
  • /usr/include/GL/gl.h - the main OpenGL header +
  • /usr/include/GL/glu.h - the OpenGL GLU (utility) header +
  • /usr/include/GL/glx.h - the OpenGL GLX header +
  • /usr/include/GL/glext.h - the OpenGL extensions header +
  • /usr/include/GL/glxext.h - the OpenGL GLX extensions header +
  • /usr/include/GL/osmesa.h - the Mesa off-screen rendering header +
  • /usr/lib/libGL.so - a symlink to libGL.so.1 +
  • /usr/lib/libGL.so.1 - a symlink to libGL.so.1.xyz +
  • /usr/lib/libGL.so.xyz - the actual OpenGL/Mesa library. xyz denotes the +Mesa version number. +
  • /usr/lib/libGLU.so - a symlink to libGLU.so.1 +
  • /usr/lib/libGLU.so.1 - a symlink to libGLU.so.1.3.xyz +
  • /usr/lib/libGLU.so.xyz - the OpenGL Utility library. xyz denotes the Mesa +version number. +
+

+After installing XFree86/X.org and the DRI drivers, some of these files +may be symlinks into the /usr/X11R6/ tree. +

+

+The old-style Makefile system doesn't install the Mesa libraries; it's +up to you to copy them (and the headers) to the right place. +

+

+The GLUT header and library should go in the same directories. +

+
+
+ + + +

3. Runtime / Rendering Problems

+ +

3.1 Rendering is slow / why isn't my graphics hardware being used?

+

+Stand-alone Mesa (downloaded as MesaLib-x.y.z.tar.gz) doesn't have any +support for hardware acceleration (with the exception of the 3DFX Voodoo +driver). +

+

+What you really want is a DRI or NVIDIA (or another vendor's OpenGL) driver +for your particular hardware. +

+

+You can run the glxinfo program to learn about your OpenGL +library. +Look for the GL_VENDOR and GL_RENDERER values. +That will identify who's OpenGL library you're using and what sort of +hardware it has detected. +

+

+If your DRI-based driver isn't working, go to the +DRI website for trouble-shooting information. +

+ + +

3.2 I'm seeing errors in depth (Z) buffering. Why?

+

+Make sure the ratio of the far to near clipping planes isn't too great. +Look + here for details. +

+

+Mesa uses a 16-bit depth buffer by default which is smaller and faster +to clear than a 32-bit buffer but not as accurate. +If you need a deeper you can modify the parameters to + glXChooseVisual in your code. +

+ + +

3.3 Why Isn't depth buffering working at all?

+

+Be sure you're requesting a depth buffered-visual. If you set the MESA_DEBUG +environment variable it will warn you about trying to enable depth testing +when you don't have a depth buffer. +

+

Specifically, make sure glutInitDisplayMode is being called +with GLUT_DEPTH or glXChooseVisual is being +called with a non-zero value for GLX_DEPTH_SIZE. +

+

This discussion applies to stencil buffers, accumulation buffers and +alpha channels too. +

+ + +

3.4 Why does glGetString() always return NULL?

+

+Be sure you have an active/current OpenGL rendering context before +calling glGetString. +

+ + +

3.5 GL_POINTS and GL_LINES don't touch the right pixels

+

+If you're trying to draw a filled region by using GL_POINTS or GL_LINES +and seeing holes or gaps it's because of a float-to-int rounding problem. +But this is not a bug. +See Appendix H of the OpenGL Programming Guide - "OpenGL Correctness Tips". +Basically, applying a translation of (0.375, 0.375, 0.0) to your coordinates +will fix the problem. +

+ +

3.6 How can I change the maximum framebuffer size in Mesa's +swrast backend?

+

+These can be overridden by using the --with-max-width and +--with-max-height options. The two need not be equal. +

+Do note that Mesa uses these values to size some internal buffers, +so increasing these sizes will cause Mesa to require additional +memory. Furthermore, increasing these limits beyond 4096 +may introduce rasterization artifacts; see the leading comments in +src/mesa/swrast/s_tritemp.h. +

+ +
+
+ + + +

4. Developer Questions

+ +

4.1 How can I contribute?

+

+First, join the Mesa3d-dev +mailing list. +That's where Mesa development is discussed. +

+

+The +OpenGL Specification is the bible for OpenGL implemention work. +You should read it. +

+

Most of the Mesa development work involves implementing new OpenGL +extensions, writing hardware drivers (for the DRI), and code optimization. +

+ +

4.2 How do I write a new device driver?

+

+Unfortunately, writing a device driver isn't easy. +It requires detailed understanding of OpenGL, the Mesa code, and your +target hardware/operating system. +3D graphics are not simple. +

+

+The best way to get started is to use an existing driver as your starting +point. +For a software driver, the X11 and OSMesa drivers are good examples. +For a hardware driver, the Radeon and R200 DRI drivers are good examples. +

+

The DRI website has more information about writing hardware drivers. +The process isn't well document because the Mesa driver interface changes +over time, and we seldome have spare time for writing documentation. +That being said, many people have managed to figure out the process. +

+

+Joining the appropriate mailing lists and asking questions (and searching +the archives) is a good way to get information. +

+ + +

4.3 Why isn't GL_EXT_texture_compression_s3tc implemented in Mesa?

+

+The specification for the extension +indicates that there are intellectual property (IP) and/or patent issues +to be dealt with. +

+

We've been unsucessful in getting a response from S3 (or whoever owns +the IP nowadays) to indicate whether or not an open source project can +implement the extension (specifically the compression/decompression +algorithms). +

+

+In the mean time, a 3rd party plug-in library is available. +

Mesa fbdev/DRI Drivers

+
+ +

1. Introduction

+ +

+The fbdev/DRI environment supports hardware-accelerated 3D rendering without +the X window system. This is typically used for embedded applications. +

+ +

+Contributors to this project include Jon Smirl, Keith Whitwell and Dave Airlie. +

+ +

+Applications in the fbdev/DRI environment use +the MiniGLX interface to choose pixel +formats, create rendering contexts, etc. It's a subset of the GLX and +Xlib interfaces allowing some degree of application portability between +the X and X-less environments. +

+ +

+Note that this environment is not well-supported and these instructions +may not be completely up to date. +

+
+ + + +

2. Compilation

+

+ +

2.1 glxproto

+ +Get glxproto.h. Copy it to the /mesa/include/GL/ directory. +

+ +

2.2 libpciaccess

+

+Check if you have libpciaccess installed: +

+ +
pkg-config --modversion pciaccess
+
+

+If not you can download the latest code from: +

+
   git clone git://anongit.freedesktop.org/git/xorg/lib/libpciaccess
+
+

+Run autogen.sh to generate a configure file. autogen.sh uses autoconf +utility. This utility may not be installed with your linux distro, +check if it is available. if not you can use your package manager or +type: +

+
sudo apt-get install autoconf
+
+The next step is to install the libpciaccess library. +
make
+make install
+
+

Now your libpciaccess.a file is saved into /usr/local/lib +directory. If you have a libpciaccess.a in /usr/lib you may simply copy +and overwrite these files. Don't forget to copy libpciaccess.pc file to +/usr/lib/pkgconfig, which is also located in /usr/local/lib/pkgconfig/. +Or you may use the following system variables: +

+
export LD_LIBRARY_PATH=/usr/local/lib
+export PKG_CONFIG_PATH=/usr/local/lib/pkgconfig
+
+ +

2.3 drm

+ +

The next step is to compile the drm. DRM consists of two seperate parts, +the DRM client library(lindrm.so) and kernel device module(such as +radeon.ko). We need to make a small change in kernel device module. So +you need to download the kernel source. You may choose the nearest +mirror from www.kernel.org, or you are using Fedora Core 5, for +example, you may need to install RPMs such as: +kernel-smp-devel-2.16.15-1.2054_FC5.i686.rpm +kernel-devel-2.6.15-1.2054_FC5.i686.rpm +etc. You can find a detailed information here. +

+ +

You will find drm_drv.c at /usr/src/LINUX-VERSION/drivers/char/drm/. Edit this code and comment out the following part: +

+ +
+   /* ||
+   ((ioctl->flags & DRM_MASTER) && !priv->master)*/
+
+Now you are ready to compile your kernel. If your kernel version is +identical to the version you have compiled, you can simply over write +your new "ko" files over older ones. If you have compiled a different +kernel, you must configure your grub or lilo to be able to boot your +new kernel.

+You'll need fbdev header files. Check with: +

+
+   ls -l /usr/include/linux/fb.
+
+

This file may be missing if you have not installed linux header files. + + +

2.4 Mesa

+ +

Get latest development Mesa sources from git repository +(currently 7.1-prerelease) +

+
+   git clone git://anongit.freedesktop.org/git/mesa/mesa
+
+ +

You will need the makedepend utility which is a part of mesa project +to build your linux-solo. You probably wont have this utility. You can +download its source from following git repulsitory: +

+
+   git clone git://anongit.freedesktop.org/git/xorg/util/makedepend
+
+ +

Get the latest stable mesa version from SourceForge (currently 7.0.3) +http://sourceforge.net/project/showfiles.php?group_id=3 +

+ +

Copy the miniglx folder from 7.1-prerelease to 7.0.3. +You may also extract GLUT to 7.0.3 version at this step. +

+ +

Edit linux-solo.conf at /conf directory, just only compile the +graphics driver you need, delete the unwanted drivers names from the +list(some drivers are causing problems...) +

+
+   while(build==0)
+   {
+     make linux-solo
+
+     There will be some missing header files, copy them from 7.1-prerelease
+   }
+
+ +

+When complete you should have the following: +

+
    +
  • lib/libGL.so - the GL library which applications link with +
  • lib/*_dri_so - DRI drivers +
  • lib/miniglx.conf - sample MiniGLX config file +
  • progs/miniglx/* - several MiniGLX sample programs +
+ +To install these files into appropriate locations in system: +
+   make install
+
+ +Now your openGL libraries are copied to /usr/local/lib and +miniglx.conf is copied to /etc. You may copy them to /usr/lib and +overwrite your old GL libraries. Or you may export following variable: + +
+   export LIBGL_DRIVERS_PATH=/usr/local/lib
+
+
+ + +

3. Using fbdev/DRI

+ +

+If an X server currently running, exit/stop it so you're working from +the console. Following command shuts down the x window and also the multi user support. +

+
+   init 1
+
+ +

Also you may define the runlevel as 1 in "/etc/inittab". Your system +will always start in single user mode and without x-window with this +option set. +

3.1 Load Kernel Modules

+ +

+You'll need to load the kernel modules specific to your graphics hardware. +Typically, this consists of the agpgart module, an fbdev driver module +and the DRM kernel module. +

+

+As root, the kernel modules can be loaded as follows: +

+ +

+If you have Intel i915/i945 hardware: +

+
   modprobe agpgart            # the AGP GART module
+   modprobe intelfb            # the Intel fbdev driver
+   modprobe i915               # the i915/945 DRI kernel module
+
+ +

+If you have ATI Radeon/R200 hardware: +

+
   modprobe agpgart            # the AGP GART module
+   modprobe radeonfb           # the Radeon fbdev driver
+   modprobe radeon             # the Radeon DRI kernel module
+
+ +

+If you have ATI Rage 128 hardware: +

+
   modprobe agpgart            # the AGP GART module
+   modprobe aty128fb           # the Rage 128 fbdev driver
+   modprobe r128               # the Rage 128 DRI kernel module
+
+ +

+If you have Matrox G200/G400 hardware: +

+
   modprobe agpgart            # the AGP GART module
+   modprobe mgafb              # the Matrox fbdev driver
+   modprobe mga                # the Matrox DRI kernel module
+
+ +

+To verify that the agpgart, fbdev and drm modules are loaded: +

+
   ls -l /dev/agpgart /dev/fb* /dev/dri
+
+

+Alternately, use lsmod to inspect the currently installed modules. +If you have problems, look at the output of dmesg. +

+ + +

3.2 Configuration File

+ +

+review/edit /etc/miniglx.conf. +Alternately, the MINIGLX_CONF environment variable can be used to +indicate the location of miniglx.conf +

+ +To determine the pciBusID value, run lspci and examine the output. +For example: +

+
   /sbin/lspci:
+   00:02.0 VGA compatible controller: Intel Corporation 82915G/GV/910GL Express Chipset Family Graphics Controller (rev 04)
+
+

+00:02.0 indicates that pciBusID should be PCI:0:2:0 +

+ + + + +

3.3 Running fbdev/DRI Programs

+ +

+Make sure your LD_LIBRARY_PATH environment variable is set to the +location of the libGL.so library. You may need to append other paths +to LD_LIBRARY_PATH if libpciaccess.so is in a non-standard location, +for example. +

+ +

+Change to the Mesa/progs/miniglx/ directory and +start the sample_server program in the background: +

+
   ./sample_server &
+
+ +

+Then try running the miniglxtest program: +

+
   ./miniglxtest
+
+

+You should see a rotating quadrilateral which changes color as it rotates. +It will exit automatically after a bit. +

+ +

+If you run other tests in the miniglx/ directory, you may want to run +them from a remote shell so that you can stop them with ctrl-C. +

+
+ + +

4.0 Troubleshooting

+ +
    +
  1. +If you try to run miniglxtest and get the following: +
    +
       [miniglx] failed to probe chipset
+   connect: Connection refused
+   server connection lost
+
    +It means that the sample_server process is not running. +
    +
    +
    2. +
+ + +

5.0 Programming Information

+ +

+OpenGL/Mesa is interfaced to fbdev via the MiniGLX +interface. +MiniGLX is a subset of Xlib and GLX API functions which provides just +enough functionality to setup OpenGL rendering and respond to simple +input events. +

+ +

+Since MiniGLX is a subset of the usual Xlib and GLX APIs, programs written +to the MiniGLX API can also be run on full Xlib/GLX implementations. +This allows some degree of flexibility for software development and testing. +

+ +

+However, the MiniGLX API is not binary-compatible with full Xlib/GLX. +Some of the structures are different and some macros/functions work +differently. +See the GL/miniglx.h header file for details. +

Mesa glFBDev Driver

+ + +

1. Introduction

+ +

+The GLFBDev driver interface allows one to do OpenGL rendering into a +framebuffer managed with the Linux's fbdev interface. +

+ +

+Basically, the programmer uses the fbdev functions to initialize the +graphics hardware and setup the framebuffer. +Then, using a calls to Mesa's glFBDev API functions, one can render +into the framebuffer with the OpenGL API functions. +

+ +

+Note, only software rendering is supported; there is no hardware +acceleration. +

+ + +

+The GL/glfbdev.h header file defines the glFBDev interface. +

+ +

+The progs/fbdev/glfbdevtest.c demonstrates how to use the glFBDev interface. +

+ + +

+For more information about fbdev, see the + +Framebuffer Howto +

+

+You will need at minimum, a framebuffer device, check /dev/fb0 +

+ +

2. Compilation

+ +

+To compile Mesa with support for the glFBDev interface: +

+      make realclean
+      make linux-fbdev
+
+ +

+When compilation is finished look in progs/glfbdev/ for the glfbdevtest demo. +

+

3. Permissions

+ +

+Typically /dev/fb/0 is grouped to the video group. It may be useful to add +your user to the video group so the demos will not have to be run as root. +To use fbdevglut with the prefered tty input, you should add the user to the +tty group as well +

+ +

4. Using fbdevglut

+Almost all of the programs in the progs directory use glut, and they compile with fbdevglut. + +

+To compile the redbook sample programs: +

+       cd progs/redbook
+       make
+
+

+

glut features not supported: +

  • Overlays +
  • Subwindows +
  • Input devices other than Keyboard/Mouse +
  • No support for GLUT_MULTISAMPLE, GLUT_STEREO, or GLUT_LUMINANCE +
  • Cursor and Menu Support will flicker in GLUT_SINGLE mode + +

    Keyboard input is read by opening /dev/tty and reading keycodes in medium raw mode. +

    Mouse input is read from env var MOUSE, or /dev/gpmdata and should be in ms3 format. +To forward data in this format to /dev/gpmdata, run gpm with the -Rms3 option. +

    glutInit allows glut programs to pass parameters to the glut library, currently the +following options are supported for fbdevglut: +

  • -geometry widthxheight -- This will force the resolution to be widthxheight instead of autodetecting. +The modes are read from /etc/fb.modes +

  • -bpp -- This will force the bitdepth to the one specified +

  • -vt -- This allows you to specify the virtual terminal to attach keyboard input to. It is useful to specify when running inside screen. +

  • -mousespeed -- A floating point multiplication factor to increase mouse speed +

  • -nomouse -- Disable mouse support +

  • -nokeyboard -- Disable keyboard support (this will probably break mouse support as well) +

  • -stdin -- Use stdin for input instead of attaching to kbd in medium-raw mode. +This will make it impossible to detect keypresses like Shift+Tab, you will also need to specify -gpmmouse for mouse support. This option can be used with a debugger, and it is possible to single step a program with gdb and set the FRAMEBUFFER environment variable to a different framebuffer for display. The program will not be able to handle vt switching on it's own, so it will always display. +

  • -gpmmouse -- This will attempt to connect to the /dev/gpmctl socket using liblow +for mouse data. Gpm does not provide this data when in graphics mode, so vt switching +will briefly display text. This mode typically has no initial mouse delay. +

  • -- Ignore any additional arguments +

    Notes: +

    +1. The mouse pointer flickers in single buffering mode, as it must be rendered in software. Hopefully in the future there will be a way to access hardware cursors in fbdev devices. +

    +The SI GLU library implements GLU version 1.3 whereas the original +Mesa GLU library only implemented version 1.2. +We recommend using the SI GLU library instead of Mesa's GLU library +since it's more up-to-date, complete and reliable. +We're no longer developing the original Mesa GLU library. +

    Help Wanted / To-Do List

    + +

    +We can always use more help with the Mesa project. +Here are some specific ideas and areas where help would be appreciated: +

    + +
      +
    1. +Driver patching and testing. +Patches are often posted to the mesa3d-dev mailing list, but aren't +immediately checked into git because not enough people are testing them. +Just applying patches, testing and reporting back is helpful. +
    2. +Driver debugging. +There are plenty of open bugs in the bug database. +
    3. +Remove aliasing warnings. +Enable gcc -Wstrict-aliasing=2 -fstrict-aliasing and track down aliasing +issues in the code. +
    4. +Windows driver building, testing and maintenance. +The Visual Studio project files aren't always updated in a timely manner +when new source files are added or old ones are removed. +Fixing these tends to delay new Mesa releases. +
    5. +Maintenance and testing of lesser-used drivers. +Drivers such as DOS/DJGPP, GGI, etc that aren't being maintained are being +deprecated starting in Mesa 7.3. +
    6. +Contribute more tests to +glean. +
    7. +Automatic testing. + +It would be great if someone would set up an automated system for grabbing +the latest Mesa code and run tests (such as glean) then report issues to +the mailing list. +
    + + +

    +If you want to do something new in Mesa, first join the Mesa developer's +mailing list. +Then post a message to propose what you want to do, just to make sure +there's no issues. +

    + +

    +Anyone is welcome to contribute code to the Mesa project. +By doing so, it's assumed that you agree to the code's licensing terms. +

    + +

    +Finally: +

    + +

      +
    1. Try to write high-quality code that follows the existing style. +

    1.1 Prerequisites for DRI and hardware acceleration

    + +

    +The following are required for DRI-based hardware acceleration with Mesa 7.3: +

    + +
      +
    • dri2proto version 1.99.3 or later +
    • Linux 2.6.28 +
    • libDRM +version 2.4.3 or later +
    • Xorg server version 1.5 or later +
    +

    + + + +

    1.2 Building with Autoconf

    + +

    +Mesa may be built using autoconf. +This should work well on most GNU-based systems. +If that fails the traditional Mesa build system is available. + + + + +

    1.3 Building with traditional Makefiles

    + +

    +The traditional Mesa build system is based on a collection of pre-defined +system configurations. +

    +

    +To see the list of configurations, just type make. +Then choose a configuration from the list and type make +configname. +

    + +

    +Mesa may be built in several different ways using the predefined configurations: +

    +
      +
    • Stand-alone/Xlib mode - Mesa will be compiled as +a software renderer using Xlib to do all rendering. +The libGL.so library will be a self-contained rendering library that will +allow you to run OpenGL/GLX applications on any X server (regardless of +whether it supports the GLX X server extension). +You will not be able to use hardware 3D acceleration. +

      +To compile stand-alone Mesa type make in the top-level directory. +You'll see a list of supported system configurations. +Choose one from the list (such as linux-x86), and type: +

      +
      +    make linux-x86
+
      +

      This will produce libGL.so and several other libraries

      +
      • + +
    • DRI/accelerated - The DRI hardware drivers for +accelerated OpenGL rendering (for ATI, Intel, Matrox, etc) will be built. +The libGL.so library will support the GLX extension and will load/use +the DRI hardware drivers. + + +

      +Build Mesa and the DRI hardware drivers by running +

      +
      +   make linux-dri
+
      +

      +There are also linux-dri-x86, linux-dri-x86-64, +and linux-ppc configurations which are optimized for those +architectures. +

      +

      +Make sure you have the prerequisite versions of DRM and Xserver mentioned +above. +

      + +
      • + +
    + + +

    +Later, if you want to rebuild for a different configuration run +make realclean before rebuilding. +

    + + +     +

    1.4 The libraries

    + +

    +When compilation has finished, look in the top-level lib/ +(or lib64/) directory. +You'll see a set of library files similar to this: +

    1.5 Running the demos

    + +

    +If you downloaded/unpacked the MesaDemos-x.y.z.tar.gz archive or +obtained Mesa from CVS, the progs/ directory will contain a +bunch of demonstration programs. +

    + +

    +Before running a demo, you'll probably have to set two environment variables +to indicate where the libraries are located. For example: +

    +

    +cd lib/ +
    +export LD_LIBRARY_PATH=${PWD} +
    +export LIBGL_DRIVERS_PATH=${PWD} (if using DRI drivers) +
    + +

    +Next, change to the Mesa/demos/ directory: +

    +
    +cd ../progs/demos +
    + +

    +Run a demo such as gears: +

    +
    +./gears +
    + +

    +If this doesn't work, try the Mesa/progs/xdemos/glxinfo program +and see that it prints the expected Mesa version number. +

    + +

    +If you're using Linux or a similar OS, verify that the demo program is +being linked with the proper library files: +

    +
    +ldd gears +
    + +

    +You should see something like this: +

    +
    +        libglut.so.3 => /home/brian/Mesa/lib/libglut.so.3 (0x40013000)
+        libGLU.so.1 => /home/brian/Mesa/lib/libGLU.so.1 (0x40051000)
+        libGL.so.1 => /home/brian/Mesa/lib/libGL.so.1 (0x400e0000)
+        libc.so.6 => /lib/i686/libc.so.6 (0x42000000)
+        libm.so.6 => /lib/i686/libm.so.6 (0x403da000)
+        libX11.so.6 => /usr/X11R6/lib/libX11.so.6 (0x403fc000)
+        libXmu.so.6 => /usr/X11R6/lib/libXmu.so.6 (0x404da000)
+        libXt.so.6 => /usr/X11R6/lib/libXt.so.6 (0x404f1000)
+        libXi.so.6 => /usr/X11R6/lib/libXi.so.6 (0x40543000)
+        libstdc++.so.5 => /usr/lib/libstdc++.so.5 (0x4054b000)
+        libgcc_s.so.1 => /lib/libgcc_s.so.1 (0x405fd000)
+        libXext.so.6 => /usr/X11R6/lib/libXext.so.6 (0x40605000)
+        libpthread.so.0 => /lib/i686/libpthread.so.0 (0x40613000)
+        /lib/ld-linux.so.2 => /lib/ld-linux.so.2 (0x40000000)
+        libdl.so.2 => /lib/libdl.so.2 (0x40644000)
+        libSM.so.6 => /usr/X11R6/lib/libSM.so.6 (0x40647000)
+        libICE.so.6 => /usr/X11R6/lib/libICE.so.6 (0x40650000)
+
    + +

    +Retrace your steps if this doesn't look right. +

    + + +     +

    1.6 Installing the header and library files

    + +

    +The standard location for the OpenGL header files on Unix-type systems is +in /usr/include/GL/. +The standard location for the libraries is /usr/lib/. +For more information see, the + +Linux/OpenGL ABI specification. +

    + +

    +If you'd like Mesa to co-exist with another implementation of OpenGL that's +already installed, you'll have to choose different directories, like +/usr/local/include/GL/ and /usr/local/lib/. +

    + +

    +To install Mesa's headers and libraries, run make install. +But first, check the Mesa/configs/default file and examine the values +of the INSTALL_DIR and DRI_DRIVER_INSTALL_DIR variables. +Change them if needed, then run make install. +

    + +

    +The variable +DESTDIR may also be used to install the contents to a temporary +staging directory. +This can be useful for package management. +For example: make install DESTDIR=/somepath/ +

    + +

    +Note: at runtime you can use the LD_LIBRARY_PATH environment variable +(on Linux at least) to switch +between the Mesa libraries and other vendor's libraries whenever you want. +This is a handy way to compare multiple OpenGL implementations. +

    + + + +

    1.7 Building OpenGL programs with pkg-config

    + +

    +Running make install will install package configuration files +for the pkg-config utility. +

    + +

    +When compiling your OpenGL application you can use pkg-config to determine +the proper compiler and linker flags. +

    + +

    +For example, compiling and linking a GLUT application can be done with: +

    +
    +   gcc `pkg-config --cflags --libs glut` mydemo.c -o mydemo
+
    + +
    + +     +

    2. Windows Compilation and Installation

    + +

    +Please see the instructions on building with SCons. +Alternatively see README.WIN32 file. +

    + + + + +

    3. Building with SCons

    + +

    +To build Mesa with SCons on Linux or Windows do +

    +
    +    scons
+
    +

    +The build output will be placed in +build/platform-machine-debug/..., where platform is for +example linux or windows, machine is x86 or x86_64, optionally followed +by -debug for debug builds. +

    + +

    +The sample programs are built seperately. To build them do +

    +    scons -C progs
+
    +And the build output will be placed in progs/build/... +

    + +

    +To build Mesa with SCons for Windows on Linux using the MinGW crosscompiler toolchain do +

    +
    +    scons platform=windows toolchain=crossmingw machine=x86 statetrackers=mesa drivers=softpipe,trace winsys=gdi
+    scons -C progs platform=windows toolchain=crossmingw machine=x86 -k
+
    +

    +This will create: +

    +
      +
    • build/windows-x86-debug/gallium/winsys/gdi/opengl32.dll — Mesa + Gallium + softpipe, binary compatible with Windows's opengl32.dll +
    • build/windows-x86-debug/glut/glx/glut32.dll +
    • progs/build/windows-x86-debug/wgl/wglinfo.exe +
    • progs/build/windows-x86-debug/trivial/tri.exe +
    • and many other samples in progs/build/windows-x86-debug/... +
    +

    +Put them all in the same directory to test them. +

    + + +     +

    Introduction

    + +

    +Mesa is an open-source implementation of the +OpenGL specification - +a system for rendering interactive 3D graphics. +

    + +

    +A variety of device drivers allows Mesa to be used in many different +environments ranging from software emulation to complete hardware acceleration +for modern GPUs. +

    + +

    +Mesa ties into several other open-source projects: the +Direct Rendering +Infrastructure and X.org to +provide OpenGL support to users of X on Linux, FreeBSD and other operating +systems. +

    + + + +

    Project History

    + +

    +The Mesa project was originally started by Brian Paul. +Here's a short history of the project. +

    + +

    +August, 1993: I begin working on Mesa in my spare time. The project +has no name at that point. I was simply interested in writing a simple +3D graphics library that used the then-new OpenGL API. I was partially +inspired by the VOGL library which emulated a subset of IRIS GL. +I had been programming with IRIS GL since 1991. +

    + +

    +November 1994: I contact SGI to ask permission to distribute my OpenGL-like +graphics library on the internet. SGI was generally receptive to the +idea and after negotiations with SGI's legal department, I get permission +to release it. +

    + +

    +February 1995: Mesa 1.0 is released on the internet. I expected that +a few people would be interested in it, but not thousands. +I was soon receiving patches, new features and thank-you notes on a +daily basis. That encouraged me to continue working on Mesa. The +name Mesa just popped into my head one day. SGI had asked me not to use +the terms "Open" or "GL" in the project name and I didn't +want to make up a new acronym. Later, I heard of the Mesa programming +language and the Mesa spreadsheet for NeXTStep. +

    + +

    +In the early days, OpenGL wasn't available on too many systems. +It even took a while for SGI to support it across their product line. +Mesa filled a big hole during that time. +For a lot of people, Mesa was their first introduction to OpenGL. +I think SGI recognized that Mesa actually helped to promote +the OpenGL API, so they didn't feel threatened by the project. +

    + + +

    +1995-1996: I continue working on Mesa both during my spare time and during +my work hours at the Space Science and Engineering Center at the University +of Wisconsin in Madison. My supervisor, Bill Hibbard, lets me do this because +Mesa is now being using for the Vis5D project. +

    +October 1996: Mesa 2.0 is released. It implements the OpenGL 1.1 specification. +

    + +

    +March 1997: Mesa 2.2 is released. It supports the new 3dfx Voodoo graphics +card via the Glide library. It's the first really popular hardware OpenGL +implementation for Linux. +

    + +

    +September 1998: Mesa 3.0 is released. It's the first publicly-available +implementation of the OpenGL 1.2 API. +

    + +

    +March 1999: I attend my first OpenGL ARB meeting. I contribute to the +development of several official OpenGL extensions over the years. +

    + +

    +September 1999: I'm hired by Precision Insight, Inc. Mesa is a key +component of 3D hardware acceleration in the new DRI project for XFree86. +Drivers for 3dfx, 3dLabs, Intel, Matrox and ATI hardware soon follow. +

    + +

    +October 2001: Mesa 4.0 is released. +It implements the OpenGL 1.3 specification. +

    + + +

    +November 2001: I cofound +Tungsten Graphics, Inc. with Keith Whitwell, Jens Owen, David Dawes and +Frank LaMonica. +I continue to develop Mesa as part of my resposibilities with Tungsten +Graphics and as a spare-time project. +

    + +

    +November 2002: Mesa 5.0 is released. +It implements the OpenGL 1.4 specification. +

    + +

    +January 2003: Mesa 6.0 is released. It implements the OpenGL 1.5 +specification as well as the GL_ARB_vertex_program and +GL_ARB_fragment_program extensions. +

    + +

    +June 2007: Mesa 7.0 is released, implementing the OpenGL 2.1 specification +and OpenGL Shading Language. +

    + + +

    +Ongoing: Mesa is used as the core of many hardware OpenGL drivers for +the XFree86 and X.org X servers within the +DRI project. +I continue to enhance Mesa with new extensions and features. +

    + + + +

    Mailing Lists

    + + +

    There are four Mesa 3D / DRI mailing lists: +

    + +
      +
    • mesa3d-announce - announcements of new Mesa +versions are sent to this list. +
      • +
      +
    • mesa3d-users - intended for users of the Mesa and DRI. +Newbie questions are appropriate, but please try the general OpenGL +resources and Mesa/DRI documentation first. +
      • +
      +
    • mesa3d-dev - for discussion of Mesa and Direct Rendering +Infrastructure development. Not for beginners. +
      • +
      +
    • mesa-commit - relays git check-in messages +(for developers). +
      +Note: the old mesa3d-cvs list is no longer in use. +
      • +
    + +

    For mailing lists about Direct Rendering Modules (drm) in Linux/BSD +kernels, see wiki. + +

    Function Name Mangling

    + +

    +If you want to use both Mesa and another OpenGL library in the same +application at the same time you may find it useful to compile Mesa with +name mangling. +This results in all the Mesa functions being prefixed with +mgl instead of gl. +

    + +

    +To do this, recompile Mesa with the compiler flag -DUSE_MGL_NAMESPACE. +Add the flag to CFLAGS in the configuration file which you want to use. +For example: +

    May 1999 - John Carmack of id Software, Inc. has made a donation of
+US$10,000 to the Mesa project to support its continuing development.
+Mesa is a free implementation of the OpenGL 3D graphics library and id's
+newest game, Quake 3 Arena, will use Mesa as the 3D renderer on Linux.
+
+The donation will go to Keith Whitwell, who has been optimizing Mesa to
+improve performance on 3d hardware.  Thanks to Keith's work, many
+applications using Mesa 3.1 will see a dramatic performance increase
+over Mesa 3.0.  The donation will allow Keith to continue working on
+Mesa full time for some time to come.
+
+For more information about Mesa see www.mesa3d.org.  For more
+information about id Software, Inc. see www.idsoftware.com.

    OpenVG State Tracker

    + +

    +The current version of the OpenVG state tracker implements OpenVG 1.0. +

    +

    +More informations about OpenVG can be found at + +http://www.khronos.org/openvg/ . +

    +

    +The OpenVG state tracker depends on the Gallium architecture and a working EGL implementation. +

    + + +

    Building the library

    +
      +
    1. Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries and EGL will suffice
      2. +
    2. cd src/gallium/state_trackers/vega; make
      3. +
    3. The last step will build libOpenVG library. You can add the libdir to LD_LIBRARY_PATH or install libOpenVG
      4. +
    + +

    Sample build

    +A sample build looks as follows: +
    +  make linux-x86-64-debug
+  cd src/gallium/state_trackers/vega
+  make
+  cd ../../../..
+  export LD_LIBRARY_PATH=$PWD/lib64
+  export EGL_DRIVER="egl_softpipe"
+
    + +

    OpenVG Demos

    + +

    +To build the OpenVG demos: +

    +
    +  cd progs/openvg
+  make
+
    +

    +To run a demo: +

    +
    +  cd openvg/demos
+  ./lion
+
    + + +

    Notes

    +
      +
    • EGL_DRIVER environmental variable: forces usage of a specific EGL driver. Unless you force egl_softpipe the implementation will look for a DRI hardware accelerate driver and unless you have a Gallium driver that supports it, you'll see crashes

    Off-screen Rendering

    + + +

    +Mesa's off-screen rendering interface is used for rendering into +user-allocated blocks of memory. +That is, the GL_FRONT colorbuffer is actually a buffer in main memory, +rather than a window on your display. +There are no window system or operating system dependencies. +One potential application is to use Mesa as an off-line, batch-style renderer. +

    + +

    +The OSMesa API provides three basic functions for making off-screen +renderings: OSMesaCreateContext(), OSMesaMakeCurrent(), and +OSMesaDestroyContext(). See the Mesa/include/GL/osmesa.h header for +more information about the API functions. +

    + +

    +There are several examples of OSMesa in the progs/osdemo/ +directory. +

    + + +

    Deep color channels

    + +

    +For some applications 8-bit color channels don't have sufficient +precision. +OSMesa supports 16-bit and 32-bit color channels through the OSMesa interface. +When using 16-bit channels, channels are GLushorts and RGBA pixels occupy +8 bytes. +When using 32-bit channels, channels are GLfloats and RGBA pixels occupy +16 bytes. +

    + +

    +Before version 6.5.1, Mesa had to be recompiled to support exactly +one of 8, 16 or 32-bit channels. +With Mesa 6.5.1, Mesa can be compiled for either 8, 16 or 32-bit channels +and render into any of the smaller size channels. +For example, if Mesa's compiled for 32-bit channels, you can also render +16 and 8-bit channel images. +

    + +

    +To build Mesa/OSMesa for 16 and 8-bit color channel support: +

    +      make realclean
+      make linux-osmesa16
+
    + +

    +To build Mesa/OSMesa for 32, 16 and 8-bit color channel support: +

    +      make realclean
+      make linux-osmesa32

    + +

    +You'll wind up with a library named libOSMesa16.so or libOSMesa32.so. +Otherwise, most Mesa configurations build an 8-bit/channel libOSMesa.so library +by default. +

    + +

    +If performance is important, compile Mesa for the channel size you're +most interested in. +

    + +

    +If you need to compile on a non-Linux platform, copy Mesa/configs/linux-osmesa16 +to a new config file and edit it as needed. Then, add the new config name to +the top-level Makefile. Send a patch to the Mesa developers too, if you're +inclined. +

    PBuffer Rendering

    + +

    +Basically, FBconfigs and PBuffers allow you to do off-screen rendering +with OpenGL. The OSMesa interface does basically the same thing, but +fbconfigs and pbuffers are supported by more vendors. +PBuffer rendering may also be hardware accelerated. +

    + +

    +PBuffers are getting more use nowadays, though they've actually been +around for a long time on IRIX systems and other workstations. +

    + +

    +The +GL_SGIX_fbconfig +and + +GL_SGIX_pbuffer extensions describe the functionality. +More recently, these extensions have been promoted to ARB extensions (on +Windows at least). +

    + +

    +The Mesa/progs/xdemos/ directory has some useful code for working +with pbuffers: +

    + +
      +
    • pbinfo.c - like glxinfo, it prints a list of available + fbconfigs and whether each supports pbuffers. +
    • pbutil.c - a few utility functions for dealing with + fbconfigs and pbuffers. +
    • pbdemo.c - a demonstration of off-screen rendering with pbuffers. +
    + +

    +Mesa 4.1 and later support GL_SGIX_fbconfig and GL_SGIX_pbuffer (software +rendering only). +

    Performance Tips

    + +

    +Performance tips for software rendering: +

    +
      + +
    1. Turn off smooth shading when you don't need it (glShadeModel) +
    2. Turn off depth buffering when you don't need it. +
    3. Turn off dithering when not needed. +
    4. Use double buffering as it's often faster than single buffering +
    5. Compile in the X Shared Memory extension option if it's supported + on your system by adding -DSHM to CFLAGS and -lXext to XLIBS for + your system in the Make-config file. +
    6. Recompile Mesa with more optimization if possible. +
    7. Try to maximize the amount of drawing done between glBegin/glEnd pairs. +
    8. Use the MESA_BACK_BUFFER variable to find best performance in double + buffered mode. (X users only) +
    9. Optimized polygon rasterizers are employed when: + rendering into back buffer which is an XImage + RGB mode, not grayscale, not monochrome + depth buffering is GL_LESS, or disabled + flat or smooth shading + dithered or non-dithered + no other rasterization operations enabled (blending, stencil, etc) +
    10. Optimized line drawing is employed when: + rendering into back buffer which is an XImage + RGB mode, not grayscale, not monochrome + depth buffering is GL_LESS or disabled + flat shading + dithered or non-dithered + no other rasterization operations enabled (blending, stencil, etc) +
    11. Textured polygons are fastest when: + using a 3-component (RGB), 2-D texture + minification and magnification filters are GL_NEAREST + texture coordinate wrap modes for S and T are GL_REPEAT + GL_DECAL environment mode + glHint( GL_PERSPECTIVE_CORRECTION_HINT, GL_FASTEST ) + depth buffering is GL_LESS or disabled +
    12. Lighting is fastest when: + Two-sided lighting is disabled + GL_LIGHT_MODEL_LOCAL_VIEWER is false + GL_COLOR_MATERIAL is disabled + No spot lights are used (all GL_SPOT_CUTOFFs are 180.0) + No local lights are used (all position W's are 0.0) + All material and light coefficients are >= zero +
    13. XFree86 users: if you want to use 24-bit color try starting your + X server in 32-bit per pixel mode for better performance. That is, + start your X server with + startx -- -bpp 32 + instead of + startx -- -bpp 24 +
    14. Try disabling dithering with the MESA_NO_DITHER environment variable. + If this env var is defined Mesa will disable dithering and the + command glEnable(GL_DITHER) will be ignored. +

    + + +

    Internal code changes

    + +

    +A number of Mesa program-related structs were renamed. +For example struct vertex_program is now struct gl_vertex_program. +All the effected drivers have been updated. +

    + +

    Ian Romanick updated the GL API dispatch code in a number of ways. +First, many old/unused extensions were removed. +Second, the static entrypoints for some extensions were removed. +This means GL function pointers will have to be used more often +(e.g. use glXGetProcAddressARB()). +

    + + +

    To Do (someday) items

    +
      +
    • Switch to freeglut +
    • Increase MAX_DRAWBUFFERS +
    • Fix linux-glide target/driver. +
    • Fix lambda calculation for frag progs. +

    New features

    +
      +
    • New DRI memory manager system. Currently used by the i915tex driver. +Other DRI drivers will be updated to use the new memory manager in coming +months. +
      +To use the new driver you'll need the most recent DRM library and drivers +(version 2.2 or later) and a recent xf86-video-intel driver module from X.org. +
      +New features resulting from this work include: +
        +
      • EXT_framebuffer_objects, render to texture +
      • ARB_pixel_buffer_objects +
      • Accelerated CopyTexSubimage, DrawPixels, ReadPixels, CopyPixels +
      • Accelerated texture uploads from pixel buffer objects +
      • Potentially texturing directly from the pixel buffer object (zero +copy texturing). +
      +
    • New Intel i965 DRI driver +
    • New minstall script to replace normal install program +
    • Faster fragment program execution in software +
    • Added (or fixed) support for + GLX_SGI_make_current_read to the following drivers:
      • +
        +
      • radeon
        • +
      • savage
        • +
      • mga
        • +
      • tdfx
        • +
      +
    • Added support for ARB_occlusion_query to the tdfx driver (Ian +Romanick).

    + + +

    Shared library numbering

    +

    +Mesa 6.5.3 supports the OpenGL 2.0/2.1 API. However, the (unix) +shared library version is still 1.5 (i.e. libGL.so.1.5.xxxxxx). +Bumping the shared library version to 2.x would cause linking problems +with existing OpenGL applications. Since OpenGL 2.x is backward +compatible with OpenGL 1.x the shared library version number doesn't +have to be incremented (which would indicate an incompatible ABI). +

    +

    +Other OpenGL vendors name their OpenGL 2.x libraries libGL.so.1.0.xxxxx +for the same reason. +

    + + + +

    New features

    +
      +
    • OpenGL 2.0 and 2.1 API support. +
    • Entirely new Shading Language code generator. See the +Shading Language page for more information. +
    • Much faster software execution of vertex, fragment shaders. +
    • New vertex buffer object (vbo) infrastructure +
    • Updated glext.h file (version 39) +
    • Updated glxext.h file (version 19) +
    • GL_MAX_DRAWBUFFERS is now 4 (software rendering) so + "multiple render targets" are really supported. +
    + +

    Bug fixes

    +
      +
    • Fog was errantly applied when a fragment shader was enabled (bug 9346) +
    • glPush/PopClientAttrib didn't handle VBO bindings correctly (bug 9445) +
    • With 32-bit Z buffer, the fragment Z of lines and points was sometimes wrong. +
    • GL_POST_CONVOLUTION_ALPHA_BIAS/SCALE was broken. +
    • 1D convolution state could effect 2D image transfers +
    • Overlapping glCopyPixels with negative Y zoom didn't work (bug 10521) +
    • Fixed a number of framebuffer/renderbuffer reference counting bugs +
    • Fixed a few bugs in software-emulated alpha planes +
    • Assorted minor bug fixes in glCopy/DrawPixels, glPixelZoom, etc. +
    • Assorted DRI driver bug fixes. +
    • Fixed a number of bugs that prevented "depth-peeling" rendering from working. +
    + + +

    Internal code changes

    +
      +
    • Old array_cache module replaced by new vbo module. All geometry +rendering is now cast in the form of vertex buffer objects. +
    • Massive changes to the Shading Language compiler and related state. +
    • Vertex/fragment shaders are compiled into GPU instructions and +programs very similar to GL_ARB_vertex/fragment_program. +
    • Vertex and fragment programs are executed with the same code now. +
    • The SSE-optimized vertex program path has been removed since it didn't +support more than 12 temp registers, didn't support branching/looping, etc. +
    + + +

    To Do (someday) items

    +
      +
    • Switch to freeglut +
    • Fix linux-glide target/driver. +
    • Improved lambda and derivative calculation for frag progs. +

    + + + +

    New Features

    +
      +
    • OpenGL Shading language support +
      + This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100, + GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of + the work was done by Michal Krol. + There's probably a fair number of bugs since this is a pretty large, + complicated body of code. +
      + The OpenGL 2.0 interface to these features will be implemented in a + future version of Mesa, + +
    • GL_EXT_timer_query +
      + Used to measure the time of OpenGL operations at high precision. + Only supported in the software/Xlib driver at this time. + +
    • GL_EXT_packed_depth_stencil +
      + Defines a new GL_DEPTH_STENCIL_EXT pixel format. + +
    • GL_EXT_framebuffer_blit +
      + A simplified glCopyPixels-like feature for copying pixel rectangles. + +
    • GL_ARB_half_float_pixel +
      + Adds a new half-precision floating point format for image transfers, + such as for glDrawPixels, glReadPixels, glTexImage, etc. +
    + +

    Changes

    +
      +
    • removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) +
    • removed GL_SGIX/SGIS_pixel_texture extensions +
    +

    Bug fixes

    +
      +
    • fixed glxcontextmodes.c datatype problem (bug 5835) +
    • fixed aix-gcc build/install bugs (bug 5874) +
    • fixed some bugs in texture env program generation +
    • glXCopyContext() didn't handle texture object bindings properly +
    • glXCopyContext() didn't copy all lighting state +
    • fixed FreeBSD config (Pedro Giffuni) +
    • fixed some minor framebuffer object bugs +
    • replaced dprintf() with _glu_printf() in GLU (bug 6244) +
    • fixed a number of thread safety bugs/regressions +
    • fixed a number of GLU tesselator bugs (John Shell, bug 6339) +
    • paletted texturing was broken w/ floating point palettes (K. Schultz) +
    • lots of assorted framebuffer object bug fixes +
    + + +

    Known Issues

    +
      +
    • Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL +textures should work. +
    + + +

    Driver Interface Changes

    +
      +
    • Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by +the two-sided versions: Driver.Stencil*Separate(). +
    • Render-to-texture: The functions for rendering to textures have changed. +
    + + +

    To Do (someday) items

    +
      +
    • Switch to freeglut +
    • Increase MAX_DRAWBUFFERS +
    • Fix linux-glide target/driver. +
    • Fix lambda calculation for frag progs. +

    Mesa 7.1 Release Notes / August 26, 2008

    + +

    +Mesa 7.1 is a new development release. +There have been many internal code changes since Mesa 7.0.x. +It should be relatively stable, but those who are especially concerned about +stability should wait for Mesa 7.2 or use Mesa 7.0.4 (the previous stable +release). +

    + +Note that this version of Mesa does not use the GEM memory manager. +The master branch of git uses GEM. +

    +

    +DRM version 2.3.1 should be used with Mesa 7.1 +

    + +

    +Mesa 7.2 is a stable release fixing bugs found in 7.1, which was a +new development release. +

    +Mesa 7.2 implements the OpenGL 2.1 API, but the version reported by +glGetString(GL_VERSION) depends on the particular driver being used. +Some drivers don't support all the features required in OpenGL 2.1. +

    +

    +Note that this version of Mesa does not use the GEM memory manager. +The master branch of git uses GEM. +The prototype DRI2 code that was in 7.1 has also been removed. +

    Mesa 7.5 Release Notes / 17 July 2009

    + +

    +Mesa 7.5 is a new development release. +People who are concerned with stability and reliability should stick +with the 7.4.x branch or wait for Mesa 7.5.1. +

    +

    +The main new feature of Mesa 7.5 is the +Gallium3D infrastructure. +

    +

    +Mesa 7.5 implements the OpenGL 2.1 API, but the version reported by +glGetString(GL_VERSION) depends on the particular driver being used. +Some drivers don't support all the features required in OpenGL 2.1. +

    +

    +See the Compiling/Installing page for prerequisites +for DRI hardware acceleration. +

    +

    +Note that the Mesa project is no longer using odd/even version numbers +to indicate development/stable releases. +The so-called development releases have been fairly stable. +If you're especially concerned with stability you should probably look for +"point" releases such as 7.5.1 which will be a bug-fix release. +

    New features

    +
      +
    • Gallium3D - this is the new architecture for OS-independent and + API-independent 3D drivers. + Gallium3D is intended for GPUs that fully support vertex/fragment shaders. + The Gallium3D drivers currently included are: +
        +
      • softpipe - a software/reference driver +
      • i915 - Intel 915/945 driver +
      • Cell - IBM/Sony/Toshiba Cell processor driver +
      • nouveau (for NVIDIA GPUs) and R300 for (AMD/ATI R300). + PLEASE NOTE: these drivers are incomplete and still under development. + It's probably NOT worthwhile to report any bugs unless you have patches. + +
      +
    • GL_ARB_framebuffer_object extension (software drivers, i965 driver) +
    • Reworked two-sided stencil support. +This allows a driver to support all three variations of two-sided stencil +including GL_ATI_separate_stencil, GL_EXT_stencil_two_side and OpenGL 2.0 +
    • GL_EXT_vertex_array_bgra extension (software drivers, i965 driver) +
    • GL_NV_texture_env_combine4 extension (software drivers, i965/i915 drivers) +
    • GL_EXT_texture_swizzle extension (software drivers, i965 driver) +
    • Updated SPARC assembly optimizations (David S. Miller) +
    • Initial support for separate compilation units in GLSL compiler. +
    • Increased max number of generic GLSL varying variables to 16 (formerly 8). +
    • GLSL linker now detects when too many varying variables are used. +
    • Optimize-out redundant glMaterial and glShadeModel calls in display lists +
    • Fixed gl_TextureMatrix[i][j] array indexing bug in GLSL compiler. +
    + + +

    Bug fixes

    +
      +
    • Lots of i965 driver bug fixes +
    • Fixed some GLSL preprocessor bugs +
    • GLSL: continue inside of a for-loop didn't work +
    + + +

    Changes

    +
      +
    • Remove support for GL_SGIX_shadow, GL_SGIX_shadow_ambient and +GL_SGIX_depth_texture extensions. Superseded by the ARB versions. +
    • Omitted some old Mesa demos from the release tarballs, added some others. +

    Code Repository

    + +

    +As of December 5, 2006, Mesa is using +git +as its source code management system. +CVS was used previously. +The old CVS repository should no longer be used. +

    + +The master git repository is hosted on +freedesktop.org. +

    + +

    +You may access the repository either as an +anonymous user (read-only) or as a +developer +(read/write). +

    + +

    +You may also +browse the git repository. +

    + + + +

    Anonymous git Access

    + +

    +To get the Mesa sources anonymously (read-only): +

    + +
      +
    1. Install the git software on your computer if needed.

      +
    2. Get an initial, local copy of the repository with: + 
      +    git clone git://anongit.freedesktop.org/git/mesa/mesa
+
      +
    3. Later, you can update your tree from the master repository with: + 
      +    git pull origin
+
      +
    + + +     +

    Developer git Access

    + +

    +Mesa developers need to first have an account on +freedesktop.org. +To get an account, please ask Brian or the other Mesa developers for +permission. +Then, if there are no objections, follow this + +procedure. +

    + +

    +Once your account is established: +

    + +
      +
    1. Install the git software on your computer if needed.

      +
    2. Get an initial, local copy of the repository with: + 
      +    git clone git+ssh://username@git.freedesktop.org/git/mesa/mesa
+
      + Replace username with your actual login name.

      +
    3. Later, you can update your tree from the master repository with: + 
      +    git pull origin
+
      +
    + + +

    Windows Users

    + +

    +If you're +using git on Windows you'll want to enable automatic CR/LF conversion in +your local copy of the repository: +

    +
    +   git config --global core.autocrlf true
+
    + +

    +This will cause git to convert all text files to CR+LF on checkout, +and to LF on commit. +

    +

    +Unix users don't need to set this option. +

    +
    + + + +

    Development Branches

    + +

    +At any given time, there may be several active branches in Mesa's +repository. +Generally, the trunk contains the latest development (unstable) +code while a branch has the latest stable code. +

    + +

    +The command git-branch will list all available branches. +

    + +

    +Questions about branch status/activity should be posted to the +mesa3d-dev mailing list. +

    Shading Language Support

    + +

    +This page describes the features and status of Mesa's support for the + +OpenGL Shading Language. +

    + +

    +Last updated on 15 December 2008. +

    + +

    +Contents +

    + + + + + +

    Environment Variables

    + +

    +The MESA_GLSL environment variable can be set to a comma-separated +list of keywords to control some aspects of the GLSL compiler: +

    +
      +
    • dump - print GLSL shader code to stdout at link time +
    • log - log all GLSL shaders to files. + The filenames will be "shader_X.vert" or "shader_X.frag" where X + the shader ID. +
    • nopt - disable compiler optimizations +
    • opt - force compiler optimizations +
    • uniform - print message to stdout when glUniform is called +
    +

    +Example: export MESA_GLSL=dump,nopt +

    + + +     +

    GLSL 1.20 support

    + +

    +GLSL version 1.20 is supported in Mesa 7.3 and later. +Among the features/differences of GLSL 1.20 are: +

      +
    • mat2x3, mat2x4, etc. types and functions +
    • transpose(), outerProduct(), matrixCompMult() functions +(but untested) +
    • precision qualifiers (lowp, mediump, highp) +
    • invariant qualifier +
    • array.length() method +
    • float[5] a; array syntax +
    • centroid qualifier +
    • unsized array constructors +
    • initializers for uniforms +
    • const initializers calling built-in functions +
    + + + +     +

    Unsupported Features

    + +

    +The following features of the shading language are not yet fully supported +in Mesa: +

    + +
      +
    • Linking of multiple shaders does not always work. Currently, linking + is implemented through shader concatenation and re-compiling. This + doesn't always work because of some #pragma and preprocessor issues. +
    • gl_ClipVertex +
    • The gl_Color and gl_SecondaryColor varying vars are interpolated + without perspective correction +
    + +

    +All other major features of the shading language should function. +

    + + +     +

    Implementation Notes

    + +
      +
    • Shading language programs are compiled into low-level programs + very similar to those of GL_ARB_vertex/fragment_program. +
    • All vector types (vec2, vec3, vec4, bvec2, etc) currently occupy full + float[4] registers. +
    • Float constants and variables are packed so that up to four floats + can occupy one program parameter/register. +
    • All function calls are inlined. +
    • Shaders which use too many registers will not compile. +
    • The quality of generated code is pretty good, register usage is fair. +
    • Shader error detection and reporting of errors (InfoLog) is not + very good yet. +
    • The ftransform() function doesn't necessarily match the results of + fixed-function transformation. +
    + +

    +These issues will be addressed/resolved in the future. +

    + + +     +

    Programming Hints

    + +
      +
    • Declare in function parameters as const whenever possible. + This improves the efficiency of function inlining. +
      • +
      +
    • To reduce register usage, declare variables within smaller scopes. + For example, the following code: +
      +    void main()
+    {
+       vec4 a1, a2, b1, b2;
+       gl_Position = expression using a1, a2.
+       gl_Color = expression using b1, b2;
+    }
+
      + Can be rewritten as follows to use half as many registers: +
      +    void main()
+    {
+       {
+          vec4 a1, a2;
+          gl_Position = expression using a1, a2.
+       }
+       {
+          vec4 b1, b2;
+          gl_Color = expression using b1, b2;
+       }
+    }
+
      + Alternately, rather than using several float variables, use + a vec4 instead. Use swizzling and writemasks to access the + components of the vec4 as floats. +
      • +
      +
    • Use the built-in library functions whenever possible. + For example, instead of writing this: +
      +        float x = 1.0 / sqrt(y);
+
      + Write this: +
      +        float x = inversesqrt(y);
+
      +
    • + Use ++i when possible as it's more efficient than i++ +
      • +
    + + +     +

    Stand-alone GLSL Compiler

    + +

    +A unique stand-alone GLSL compiler driver has been added to Mesa. +

    + +

    +The stand-alone compiler (like a conventional command-line compiler) +is a tool that accepts Shading Language programs and emits low-level +GPU programs. +

    + +

    +This tool is useful for: +

    +

      +
    • Inspecting GPU code to gain insight into compilation +
    • Generating initial GPU code for subsequent hand-tuning +
    • Debugging the GLSL compiler itself +
    + +

    +After building Mesa, the glslcompiler can be built by manually running: +

    +
    +    make realclean
+    make linux
+    cd src/mesa/drivers/glslcompiler
+    make
+
    + + +

    +Here's an example of using the compiler to compile a vertex shader and +emit GL_ARB_vertex_program-style instructions: +

    +
    +    bin/glslcompiler --debug --numbers --fs progs/glsl/CH06-brick.frag.txt
+
    +

    +results in: +

    +
    +# Fragment Program/Shader
+  0: RCP TEMP[4].x, UNIFORM[2].xxxx;
+  1: RCP TEMP[4].y, UNIFORM[2].yyyy;
+  2: MUL TEMP[3].xy, VARYING[0], TEMP[4];
+  3: MOV TEMP[1], TEMP[3];
+  4: MUL TEMP[0].w, TEMP[1].yyyy, CONST[4].xxxx;
+  5: FRC TEMP[1].z, TEMP[0].wwww;
+  6: SGT.C TEMP[0].w, TEMP[1].zzzz, CONST[4].xxxx;
+  7: IF (NE.wwww); # (if false, goto 9);
+  8:    ADD TEMP[1].x, TEMP[1].xxxx, CONST[4].xxxx;
+  9: ENDIF;
+ 10: FRC TEMP[1].xy, TEMP[1];
+ 11: SGT TEMP[2].xy, UNIFORM[3], TEMP[1];
+ 12: MUL TEMP[1].z, TEMP[2].xxxx, TEMP[2].yyyy;
+ 13: LRP TEMP[0], TEMP[1].zzzz, UNIFORM[0], UNIFORM[1];
+ 14: MUL TEMP[0].xyz, TEMP[0], VARYING[1].xxxx;
+ 15: MOV OUTPUT[0].xyz, TEMP[0];
+ 16: MOV OUTPUT[0].w, CONST[4].yyyy;
+ 17: END
+
    + +

    +Note that some shading language constructs (such as uniform and varying +variables) aren't expressible in ARB or NV-style programs. +Therefore, the resulting output is not always legal by definition of +those program languages. +

    +

    +Also note that this compiler driver is still under development. +Over time, the correctness of the GPU programs, with respect to the ARB +and NV languagues, should improve. +

    + + + +     +

    Compiler Implementation

    + +

    +The source code for Mesa's shading language compiler is in the +src/mesa/shader/slang/ directory. +

    + +

    +The compiler follows a fairly standard design and basically works as follows: +

    +
      +
    • The input string is tokenized (see grammar.c) and parsed +(see slang_compiler_*.c) to produce an Abstract Syntax Tree (AST). +The nodes in this tree are slang_operation structures +(see slang_compile_operation.h). +The nodes are decorated with symbol table, scoping and datatype information. +
    • The AST is converted into an Intermediate representation (IR) tree +(see the slang_codegen.c file). +The IR nodes represent basic GPU instructions, like add, dot product, +move, etc. +The IR tree is mostly a binary tree, but a few nodes have three or four +children. +In principle, the IR tree could be executed by doing an in-order traversal. +
    • The IR tree is traversed in-order to emit code (see slang_emit.c). +This is also when registers are allocated to store variables and temps. +
    • In the future, a pattern-matching code generator-generator may be +used for code generation. +Programs such as L-BURG (Bottom-Up Rewrite Generator) and Twig look for +patterns in IR trees, compute weights for subtrees and use the weights +to select the best instructions to represent the sub-tree. +
    • The emitted GPU instructions (see prog_instruction.h) are stored in a +gl_program object (see mtypes.h). +
    • When a fragment shader and vertex shader are linked (see slang_link.c) +the varying vars are matched up, uniforms are merged, and vertex +attributes are resolved (rewriting instructions as needed). +
    + +

    +The final vertex and fragment programs may be interpreted in software +(see prog_execute.c) or translated into a specific hardware architecture +(see drivers/dri/i915/i915_fragprog.c for example). +

    + +

    Code Generation Options

    + +

    +Internally, there are several options that control the compiler's code +generation and instruction selection. +These options are seen in the gl_shader_state struct and may be set +by the device driver to indicate its preferences: + +

    +struct gl_shader_state
+{
+   ...
+   /** Driver-selectable options: */
+   GLboolean EmitHighLevelInstructions;
+   GLboolean EmitCondCodes;
+   GLboolean EmitComments;
+};
+
    + +
      +
    • EmitHighLevelInstructions +
      +This option controls instruction selection for loops and conditionals. +If the option is set high-level IF/ELSE/ENDIF, LOOP/ENDLOOP, CONT/BRK +instructions will be emitted. +Otherwise, those constructs will be implemented with BRA instructions. +
      • + +
    • EmitCondCodes +
      +If set, condition codes (ala GL_NV_fragment_program) will be used for +branching and looping. +Otherwise, ordinary registers will be used (the IF instruction will +examine the first operand's X component and do the if-part if non-zero). +This option is only relevant if EmitHighLevelInstructions is set. +
      • + +
    • EmitComments +
      +If set, instructions will be annoted with comments to help with debugging. +Extra NOP instructions will also be inserted. +
      + +
    + + +     +

    Compiler Validation

    + +

    +A Glean test has +been create to exercise the GLSL compiler. +

    +

    +The glsl1 test runs over 170 sub-tests to check that the language +features and built-in functions work properly. +This test should be run frequently while working on the compiler to catch +regressions. +

    +

    +The test coverage is reasonably broad and complete but additional tests +should be added. +

    +

    +

    The Tungsten Graphics, Inc. Mesa subset library is hereafter +referred to as the subset.
    +
    +

    +

    2. Primitive Specification

    +

    2.1 glBegin, glEnd and glVertex Commands

    +The basic rendering primitives are points, lines and triangles. + Quadrilaterals and polygons are composed of triangles. + Primitives are drawn with the glBegin +and glEnd commands and a subset +of the glVertex commands:
    +
    +
    void glBegin(GLenummode)
    +void glEnd(void)
    +
    +void glVertex2f(GLfloat x, GLfloat y)
    +void glVertex2fv(const GLfloat +*v)
    +void glVertex3f(GLfloat x, GLfloat y, GLfloat z)
    +void glVertex3fv(const GLfloat +*v)
    +
    +
    +The mode parameter to glBegin may be one of the following
    +
    +
    GL_POINTS - a series of individual +points
    +GL_LINES - a series of disjoint line segments
    +GL_LINE_STRIP - series of connected line segments
    +GL_LINE_LOOP - a closed loop of line segments
    +GL_TRIANGLES - a series of individual triangles
    +GL_TRIANGLE_STRIP - a connected strip of triangles
    +GL_TRIANGLE_FAN - a sequence of triangles all sharing a common vertex
    +GL_QUADS - a sequence of individual quadrilaterals
    +GL_QUAD_STRIP - a connected strip of quadrilaterals
    +GL_POLYGON - a closed, convex polygon
    +
    +
    +
    +The glVertex commands take two +or three floating point coordinates, or a pointer to an array of two or +three floating point coordinates.  Vertices are actually 4-element +homogeneous coordinates.  The fourth component, unspecified by the +subset's glVertex commands, is +one.
    +
    + +

    2.2 Other Per-vertex Commands
    +

    +The glColor and glTexCoord commands may be used to +specify colors and texture coordinates for each vertex:
    +
    +
    void glColor3f(GLfloatred, GLfloat green, GLfloat blue)
    +void glColor3fv(const GLfloat *rgb)
    +void glColor4f(GLfloat red, GLfloat green, GLfloat blue, GLfloat alpha)
    +void glColor4fv(const GLfloat *rgba)
    +void glTexCoord2f(GLfloat s, GLfloat t)
    +void glTexCoord2fv(const +GLfloat *c)
    +
    +
    +The glColor commands specify +the color and optionally, the alpha value, for subsequent vertices. + For the glColor3 commands, +alpha is set to one.
    +
    +The glTexCoord2 commands +specify the texture coordinate for subsequent vertices.  Texture +coordinates are actually four-component coordinates: (s, t, r, q). + The glTexCoord2 commands +set s and t explicitly.  The r and q components are zero and one, +respectively.
    +
    +Only glVertex, glColor and glTexCoord commands are allowed +between glBegin and glEnd.  Calling any other +command between glBegin and glEnd will result in the error +GL_INVALID_OPERATION.
    +
    +

    2.3 Unsupported Commands

    +None of the following commands related to primitive specification are +supported by the subset:
    +
    +
    Per-Vertex commands:
    +

    3. Coordinate Transformation

    +

    3.1 Vertex Transformation

    +Vertex coordinates are transformed by the current modelview and +projection matrices then mapped to window coordinates as specified by +the viewport.  The following coordinate transformation commands are +supported by the subset
    +
    +
    glMatrixMode(GLenum mode)
    +glLoadIdentity(void)
    +glPushMatrix(void)
    +glPopMatrix(void)
    +glLoadMatrixf(const GLfloat *m)
    +glMultMatrixf(const GLfloat *m)
    +glRotatef(GLfloat angle, GLfloat x, GLfloat y, GLfloat z)
    +glTranslatef(GLfloat x, GLfloat y, GLfloat z)
    +glScalef(GLfloat x, GLfloat y, GLfloat z)
    +glFrustum(GLdouble left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)
    +glOrtho(GLdouble left, GLdouble right, GLdouble bottom, GLdouble top, GLdouble near, GLdouble far)
    +glViewport(GLint x, GLint y, GLsize width, GLsizei height)
    +
    +
    +The glMatrixMode command +specifies the current matrix. + The mode parameter may be GL_MODELVIEW or GL_PROJECTION to specify +the modelview matrix or projection matrix.  Subsequent matrix +commands will effect the current matrix.  Also associated with the +modelview and projection matrices are a modelview matrix stack and +projection matrix stack.
    +
    +The glLoadIdentity command +replaces the current matrix with the identity matrix.  The matrix +elements are specified in column-major order.
    +
    +The glPushMatrix command pushes +a copy of the current matrix onto either the modelview matrix stack or +the projection matrix stack.  The glPopMatrix +command replaces the current matrix with a copy of the top matrix off +the modelview matrix stack or projection matrix stack, the pops the +stack.  Matrix stacks are useful for traversing and rendering +hierarchical models.
    +
    +The glMultMatrixf command +post-multiplies the current matrix by the specified matrix.  The +matrix elements are specified in column-major order.
    +
    +The glRotatef command +post-multiplies the current matrix by a rotation matrix defined by the +angle and rotation axis defined by x, y and z.
    +
    +The glTranslatef command +post-multiplies the current matrix by a translation matrix defined by +the x, y and z translation parameters.
    +
    +The glScalef command +post-multiplies the current matrix by a scaling matrix defined by the x, y and z scale factors.
    +
    +The glFrustum command +post-multiplies the current matrix by a perspective projection matrix. + The near and far values specify the position of +the hither and yon Z-axis clipping planes.  The left, right, bottom and top parameters are the X and Y +extents at the near clipping plane.  glFrustum is normally used to modify +the projection matrix.
    +
    +The glOrtho command +post-multiplies the current matrix by an orthographic projection matrix. + The near and far values specify the position of +the hither and yon Z-axis clipping planes.  The left, right, bottom and top parameters specify the X and +Y-axis clipping planes.  glOrtho +is normally used to modify the projection matrix.
    +
    +The glViewport command +specifies the mapping of coordinates from normalized device coordinates +to window coordinates.  The x +and y parameters specify the +viewport's lower-left corner in the window and the width and height parameters specify the size +of the viewport.  glViewport +does not effect the current matrix.
    +
    +A coordinate transformed to window coordinates is hereafter known as (xw, +yw, zw).
    +
    +

    3.2 Clipping

    +View-volume clipping automatically discards or trims primitives which +lie completely or partially outside of the view volume specified by glFrustum and glOrtho.  Note that the glViewport command does not define a +clipping region.
    +
    +Clipping occurs in clip coordinate +space - the coordinates produced after applying the projection +matrix.
    +
    +

    3.3 Current Raster Position

    +The current raster position specifies the location for drawing images +with glBitmap.  The current +raster position is set with the commands:
    +
    +
    void glRasterPos2f(GLfloatx, GLfloat y)
    +void glRasterPos2fv(const +GLfloat *v)
    +void glRasterPos2i(GLint x, GLint y)
    +void glRasterPos2iv(const +GLint *v)
    +
    +
    +glRasterPos specifies a +4-component coordinate (x, y, 0, 1).  The coordinate is processed +like a vertex; it is transformed by the modelview matrix, the projection +matrix and mapped to the viewport.  The resulting window coordinate +is stored as the current raster position.  The coordinate is +clipped-tested against the frustum like a vertex.  If the +coordinate is clipped, then the current raster position becomes invalid +and subsequent glBitmap commands +have no effect.
    +
    +glRasterPos also updates the +current raster color and current raster texture coordinates.  The +current raster color is updated (copied) from the current color (as +specified by glColor). + The current raster texture coordinate is updated (copied) from the +current texture coordinate (as specified by glTexCoord).
    +
    +

    3.4 Unsupported Commands

    +The following commands related to vertex transformation are not +supported by the subset:
    +
    +
    User-defined clip plane commands:
    +
    glClipPlane
    +
    +
    +
    +
    Lighting and material commands:
    +
    glLightModeli, +glLightModelf, glLightModeliv, +glLightModelfv, glLightf, +glLighti, glLightfv, glLightiv, glColorMaterial
    +
    +
    +
    Automatic texture coordinate generation +commands:
    +
    +
    +
    glTexGend, +glTexGenf, glTexGeni, glTexGendv, +glTexGenfv, glTexGeniv,
    +
    +
    +Double-valued commands:
    +
    glLoadMatrixd, +glMultMatrixd, glRotated, glTranslated, glScaled
    +
    +
    +Depth Range command:
    +
    glDepthRange +(the near value is always 0.0 and the far value is always 1.0)
    +
    +
    +Extra RasterPos commands:
    +
    glRasterPos2d, +glRasterPos2s, glRasterPos3d, glRasterPos3f, glRasterPos3i, +glRasterPos3s, glRasterPos4d, glRasterPos4f, glRasterPos4i, +glRasterPos4s, glRasterPos2dv, glRasterPos2sv, glRasterPos3dv, +glRasterPos3fv, glRasterPos3iv, glRasterPos3sv, glRasterPos4dv, +glRasterPos4fv, glRasterPos4iv, glRasterPos4sv
    +
    +
    +
    +
    +

    4. Rasterization

    +This section describes the commands and options for drawing points, +lines, triangles and bitmaps.  Rasterization +is the term for the process which produces fragments from the geometric +description of a primitive (a point, line, polygon or bitmap).  For +example, given the two coordinates for the end-points of a line segment, +rasterization determines which pixels in the frame buffer are modified +to draw the line.  A +fragment is a tuple which consists of a window coordinate, colors and +texture coordinates.  The fragments produced by rasterization are +subsequently processed by the per-fragment operations described later.
    +
    +

    4.1 Point Rasterization

    +Points are rendered with the command sequence glBegin(GL_POINTS), glVertex, ... glEnd.  The window coordinate (xw, +yw, zw) is truncated to rasterize the point. + The truncated coordinate with its associated color and texture +coordinate is sent as a single fragment to the per-fragment processing +stages.
    +
    +The glPointSize command is not +supported; only 1-pixel points are supported.
    +
    +Point smoothing (antialiasing) is also not supported.
    +
    +

    4.2 Line Rasterization

    +Lines are rendered with the command sequence glBegin(mode), glVertex, glVertex, ... glEnd where mode is one of GL_LINES, +GL_LINE_STRIP or GL_LINE_LOOP.  Lines are rasterized as described +in the OpenGL specification.  Note that OpenGL specifies the half-open convention for drawing +lines: the last fragment in a line segment is omitted so that endpoint +pixels shared by two line segments will only be drawn once instead of +twice.
    +
    +

    4.2.1 Line Width

    +The width of lines can be controlled by
    +
    +
    void glLineWidth(GLfloatwidth)
    +
    +
    +where width is the line width +in pixels.  The width defaults to 1.0.  Attempting to set the +width to a value less than or equal to zero will raise the error +GL_INVALID_VALUE.
    +
    +

    4.2.2 Line Stipple
    +

    +Lines may be stippled (i.e. dashed) with the command
    +
    +
    glLineStipple(GLintfactor, GLushort pattern)
    +
    +
    +pattern describes an on/off +pattern for the fragments produced by rasterization and factor specifies how many subsequent +fragments are kept or culled for each pattern bit.  Line stippling +can be enabled or disabled by the commands glEnable(GL_LINE_STIPPLE) and glDisable(GL_LINE_STIPPLE).
    +
    +

    4.2.3 Line Antialiasing

    +Lines may be antialiased.  For antialiased lines, each fragment +produced by rasterization is assigned a coverage value which describes how +much of the fragment's area is considered to be inside the line.  Later, the +alpha value of each fragment is multiplied by the coverage value. + By blending the fragments into the frame buffer, the edges of +lines appear smoothed.
    +
    +Line antialiasing can be enabled or disabled with the commands glEnable(GL_LINE_SMOOTH) and glDisable(GL_LINE_SMOOTH).
    +
    +

    4.3 Polygon Rasterization

    +Polygons, quadrilaterals and triangles share the same polygon +rasterization options.
    +
    +Triangles are rendered by the command sequence glBegin(mode),glVertex, glVertex, ... glEnd where mode may be one of GL_TRIANGLES, +GL_TRIANGLE_STRIP or GL_TRIANGLE_FAN. + For GL_TRIANGLES mode, the number of vertices should be a multiple +of three - extra vertices will be ignored.  For GL_TRIANGLE_STRIP +and GL_TRIANGLE_FAN, at least three vertices should be specified. + If less than three are specified, nothing is drawn.  
    +
    +Quadrilaterals are rendered by +the command sequence glBegin(mode),glVertex, glVertex, ... glEnd where mode may be one of GL_QUADS or +GL_QUAD_STRIP.   For +GL_QUADS, the number of vertices should be a multiple of four - extra +vertices will be ignored.  For GL_QUAD_STRIP, the number of +vertices should be even and at least four.  Extra vertices (one) +will be ignored.
    +
    +Convex polygons are rendered +by the command sequence glBegin(GL_POLYGON),glVertex, glVertex, ... glEnd. + If less than three vertices are specified, nothing is drawn.
    +
    +

    4.3.1 Polygon Orientation

    +The winding order of vertices +(clockwise or counter-clockwise) is significant.  It is used to +determine the front-facing or back-facing orientation of polygons. + By default, a front-facing polygon's vertices are in +counter-clockwise order (in window coordinates).  Figures 2.4 and +2.5 of the OpenGL 1.2.1 specification illustrate the winding order for +front-facing triangles and quadrilaterals, respectively.
    +
    +The command
    +
    +
    void glFrontFace(GLenum mode)
    +
    +
    +specifies whether clockwise or counter-clockwise winding indicates a +front-facing polygon.  If mode +is GL_CW then polygons with clockwise winding are front-facing.  If mode is GL_CCW then polygons with +counter-clockwise winding are front-facing.  The default value is +GL_CCW.  If mode is not +GL_CCW or GL_CW then the error GL_INVALID_ENUM will be raised.
    +
    +

    4.3.2 Polygon Culling

    +Polygons may be culled (discarded) depending on whether they are +front-facing or back-facing.  The command
    +
    +
    void +glCullFace(GLenum mode)
    +
    +
    +specifies whether front-facing, back-facing or all polygons should be +culled.  If mode is +GL_FRONT then front-facing polygons will be culled.  If mode is GL_BACK then back-facing +polygons will be culled. Otherwise, if mode +is GL_FRONT_AND_BACK then all polygons will be culled.  Any other +value for mode will raise the +error GL_INVALID_ENUM.
    +
    +Polygon culling is enabled and disabled with the commands glEnable(GL_CULL_FACE) and glDisable(GL_CULL_FACE), +respectively.
    +
    +

    4.3.3 Polygon Antialiasing

    +Polygons may be antialiased in order to smooth their edges. + Polygon antialiasing is enabled and disabled with the commands glEnable(GL_POLYGON_SMOOTH) and glDisable(GL_POLYGON_SMOOTH).
    +
    +When polygon antialiasing is enabled each fragment produced by polygon, +triangle and quadrilateral rasterization will be given a coverage value which indicates how +much of the fragment is covered by the polygon.  Fragments +completely inside the polygon have coverage 1.0.  Fragments +completely outside the polygon have zero coverage (in theory). + Fragments which intersect the polygon's edge have a coverage value +in the range (0, 1).
    +
    +The fragment's alpha value is multiplied by the coverage value. + By enabling the appropriate blending mode, polygon edges will +appear smoothed.
    +
    +

    4.4 Shading

    +The command
    +
    +
    void glShadeModel(GLenummode)
    +
    +
    +determines whether colors are interpolated between vertices during +rasterization.  If mode is +GL_FLAT then vertex colors are not interpolated.  The color used +for drawing lines, triangles and quadrilaterals is that of the last +vertex used to specify each primitive.  For polygons, the color of +the first vertex specifies the color for the entire polygon.  If mode is GL_SMOOTH then vertex colors +are linearly interpolated to produce the fragment colors.
    +
    +

    4.5 Bitmap Rasterization

    +A bitmap is a monochromatic, binary image in which each image element +(or pixel) is represented by one bit.  Fragments are only generated +for the bits (pixels) which are set.  Bitmaps are commonly used to +draw text (glyphs) and markers.
    +
    +A bitmap is drawn with the command
    +
    +
    void glBitmap(GLsizeiwidth, GLsizei height, GLfloat xOrig, GLfloat yOrig, GLfloat xMove, GLfloat yMove, const  GLubyte *image)
    +
    +
    +width and height specify the image size in +pixels.  xOrig and yOrig specify the bitmap origin. + xMove and yMove are added to the current +raster position after the bitmap is rasterized.  image is a pointer to the bitmap +data.
    +
    +If the current raster position is not valid, glBitmap has no effect.
    +
    +

    4.5.1 Bitmap Unpacking

    +The first step in bitmap rendering is unpacking. + Unpacking is the process of extracting image data from +client memory subject to byte swapping, non-default row strides, etc. + The unpacking parameters are specified with the command
    +
    +
    void +glPixelStorei(GLenum pname, GLint value)
    +
    +
    +The following unpacking parameters may be set:
    +
    + + + + + + + + + + + + + + + + + + +
    Parameter (pname)
    +     		Value (value)
    +     		Default
    +
    GL_UNPACK_ROW_LENGTH
    +     		Width of the image in memory, in +pixels.
    +     		0
    +
    GL_UNPACK_LSB_FIRST
    +     		GL_FALSE indicates that the most +significant bit is unpacked first from each byte.  GL_TRUE +indicates that the least significant bit is unpacked first from each +byte.
    +     		GL_FALSE
    +
    +
    +
    +The GL_UNPACK_ROW_LENGTH specifies the stride (in pixels) for advancing +from one row of the image to the next.  If it's zero, the width parameter to glBitmap specifies the width of the +image in memory.
    +
    +GL_UNPACK_LSB_FIRST determines whether the least significant or most +significant bit in each byte is unpacked first.  Unpacking occurs +in left to right order (in image space).
    +
    +The value of bit (i, j) of the image (where i is the image row and j is +the image column) is found as follows:
    +
    +
    rowLength = (GL_UNPACK_ROW_LENGTH != 0) +? GL_UNPACK_ROW_LENGTH : width;
    +
    +byte = image[((rowLength + 7) +/ 8) * i + j / 8];
    +
    +if (GL_UNPACK_LSB_FIRST != 0)
    +    bitMask = 1 << (j % 8);
    +else
    +    bitMask = 128 >> (j % 8);
    +
    +if (byte & bitMask)
    +    bit = 1;
    +else
    +    bit = 0;
    +
    +
    + +

    4.5.2 Rasterization

    +If the current raster position is (xrp, yrp, zrp, +wrp), then the bitmap is rasterized according to the +following algorithm:
    +
    +for (j = 0; j < height; +j++) {
    +    for (i = 0; i < width; +i++) {
    +        if (bit(i,j)) {
    +            fragment.x = +floor(xrp - xOrig) ++ i;
    +            fragment.y = +floor(yrp - yOrig) ++ j;
    +            fragment.color += GL_CURRENT_RASTER_COLOR;
    +            +fragment.texture = GL_CURRENT_RASTER_TEXTURE_COORDS;
    +            +ProcessFragment(fragment)
    +         }
    +    }
    +}
    +
    +After the bitmap has been rendered the current raster position is +updated as follows:
    +
    +
    xrp = xrp + xMove
    +yrp = yrp + yMove
    +
    +
    +

    4.5.3 Per-fragment Operations

    +XXX supported?  See issue in appendix A.
    +
    +

    4.6 Unsupported Commands

    +The following commands related to rasterization are not supported by +the subset.
    +
    +
    Point commands:
    +
    glPointSize
    +
    +
    +Polygon commands:
    +
    glPolygonStipple
    +glPolygonOffset
    +glPolygonMode
    +
    +
    +
    +
    Pixel storage commands:
    +
    +
    glPixelStoref
    +
    +
    +
    +

    5. Texture Mapping
    +

    +There are four elements to texture mapping: texture coordinate +specification, texture image specification, texture sampling and texture +application.
    +
    +Texture mapping is enabled and disabled with the commands glEnable(GL_TEXTURE_2D) and glDisable(GL_TEXTURE_2D).
    +
    +

    5.1 Texture Image Specification

    +A texture image is specified with the command:
    +
    +
    void glTexImage2D(GLenum target, GLint level, GLint internalFormat, GLsizei width, GLsizei height, GLint border, GLenum format, GLenum type, const GLvoid *pixels )
    +
    +
    +target must be GL_TEXTURE_2D. + level indicates the +mipmap level for mipmap textures.  internalFormat +is a hint to indicate the preferred internal storage format for the +texture.  width and height indicate the image size in +pixels (or texels).  border must +be zero.  format and type describe the pixel format and +data type for the incoming image.  pixels +points to the incoming texture image.  These parameters are +described in more detail below.
    +
    +

    5.1.1 Texture Image Size and Mipmaps

    +

    +Texture images must have dimensions (width and height) that are powers +of two. For example: 256 x 256, 32 x 1024, 1 x 8, etc.  That is, it +must be the case that width = +2n and height = 2m +for some positive integers n and m.
    +
    +Mipmapping is a method of antialiasing or filtering textures to improve +their appearance.  A mipmap is a set of images consisting of a base +image and a set of filtered, reduced-resolution images.  If the +base image (level=0) is of +width 2n and height 2m then the level 1 image must +be of width 2n-1 and height 2m-1.  Each mipmap +level is half the width and height of the previous level, or at least +one.  The last mipmap level has a width and height of one.
    +
    +The following is an example of a mipmap's image levels:
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    mipmap level
    +     		width
    +     		height
    +
    0
    +     		256
    +     		64
    +
    1
    +     		128
    +     		32
    +
    2
    +     		64
    +     		16
    +
    3
    +     		32
    +     		8
    +
    4
    +     		16
    +     		4
    +
    5
    +     		8
    +     		2
    +
    6
    +     		4
    +     		1
    +
    7
    +     		2
    +     		1
    +
    8
    +     		1
    +     		1
    +
    +
    +If the width or height parameters are not powers of +two, the error GL_INVALID_VALUE is raised.  If the image levels in +a mipmap do not satisfy the restrictions listed above the texture is +considered to be inconsistent +and the system will behave as if the texturing is disabled.
    +
    +

    5.1.2 Texture Image Formats and Unpacking

    +The glTexImage2D command's format and type parameters describe the format +of the incoming texture image.  Accepted values for format are GL_INTENSITY, GL_RGB and +GL_RGBA.  The type +parameter must be GL_UNSIGNED_BYTE.  Pixel component values are +thus in the range 0 through 255.
    +
    +If format is GL_INTENSITY then +the image has one byte per pixel which specifies the pixel's red, green, +blue and alpha values.
    +
    +If format is GL_RGB then the +image has three bytes per pixel which specify the pixel's red, green and +blue values (in that order).  The alpha value defaults to 255.
    +
    +If format is GL_RGBA then the +image has four bytes per pixel which specify the pixel's red, green, +blue and alpha values (in that order).
    +
    +The command
    +
    +
    void +glPixelStorei(GLenum pname, +GLint value)
    +
    +
    +controls the unpacking of texture image data from client memory.  pname may be GL_UNPACK_ROW_LENGTH to +indicate the stride, in pixels, between subsequent rows of the image in +client memory.  If GL_UNPACK_ROW_LENGTH is zero (the default) then +the width parameter to glTexImage2D determines the stride.
    +
    +

    5.1.3 Internal Texture Format

    +glTexImage2D converts the incoming +texture image to one of the supported internal texture formats.
    +
    +The internalFormat parameter +indicates the desired internal format for the texture and may be either +GL_INTENSITY8, GL_RGB5 or GL_RGBA8.
    +
    +If internalFormat is +GL_INTENSITY8 then the texture has one byte per texel (texture element) +which indicates the texel's intensity (or brightness).  The +intensity is obtained from the incoming image's red channel.
    +
    +If internalFormat is GL_RGB5 +then the texture is stored with two bytes per texel:  5 bits per +red value, 5 bits per green value and 5 bits per blue value.
    +
    +If internalFormat is +GL_RGBA8 then the texture is stored with four bytes per texel:  8 +bits for each of the red, green,  blue and alpha values.
    +
    +The internal format is also significant to texture application (see +section 5.4).
    +
    +

    5.2 Texture Coordinates

    +Texture coordinates control the mapping from local polygon space to +texture image space.  Texture coordinates are set for each vertex +with the glTexCoord commands. + During line and polygon rasterization the vertex's texture +coordinates are interpolated across the primitive to produce a texture +coordinate for each fragment.  The fragment texture coordinates are +used to sample the current texture image.
    +
    +Texture coordinates are normally in the range [0, 1].  Values +outside that range are processed according to the texture wrap mode.  The +texture wrap mode is set with the command
    +
    +
    void glTexParameteri(GLenum target, GLenum pname, GLint value)
    +
    +
    +target must be GL_TEXTURE_2D. + If pname is +GL_TEXTURE_WRAP_S or GL_TEXTURE_WRAP_T then value must be either +GL_CLAMP_TO_EDGE or GL_REPEAT.
    +
    +For GL_CLAMP_TO_EDGE, texture coordinates are effectively clamped to +the interval [0, 1].
    +
    +For GL_REPEAT, the integer part of texture coordinates is ignored; only +the fractional part of the texture coordinates is used.  This +allows texture images to repeated or tiled across an object.
    +
    +

    5.3 Texture Sampling

    +Texture sampling is the process of using texture coordinates to extract +a color from the texture image.  Multiple, weighted samples may be +taken from the texture and combined during the filtering step.
    +
    +During texture coordinate interpolation a level of detail value (lambda) is +computed for each fragment.  For a mipmapped texture, lambda +determines which level (or levels) of the mipmap will be sampled to +obtain the texture color.
    +
    +If lambda indicates that multiple texels map to a single screen pixel, +then the texture minification +filter will be used.  Otherwise, if lambda indicates that a single +texel maps to multiple screen pixels, then the texture magnification filter will be used.
    +
    +

    5.3.1 Texture Minification

    +The texture minification filter is set with the glTexParameteri command by setting target to GL_TEXTURE_2D, setting pname to GL_TEXTURE_MIN_FILTER and +setting value to GL_NEAREST, +GL_LINEAR, GL_NEAREST_MIPMAP_NEAREST,  +GL_NEAREST_MIPMAP_LINEAR,   GL_LINEAR_MIPMAP_NEAREST or +GL_LINEAR_MIPMAP_LINEAR.
    +
    +GL_NEAREST samples the texel nearest the texture coordinate in the +level 0 texture image.
    +
    +GL_LINEAR samples the four texels around the texture coordinate in the +level 0 texture image.  The four texels are linearly weighted to +compute the final texel value.
    +
    +GL_NEAREST_MIPMAP_NEAREST samples the texel nearest the texture +coordinate in the level N texture image.  N is the level of detail +and is computed by the partial derivatives of the texture coordinates +with respect to the window coordinates.
    +
    +GL_NEAREST_MIPMAP_LINEAR samples two texels nearest the texture +coordinates in the level N and N+1 texture images.  The two texels +are linearly weighted to compute the final texel value.  N is the +level of detail and is computed by the partial derivatives of the +texture coordinates with respect to the window coordinates.
    +
    +GL_LINEAR_MIPMAP_NEAREST samples four texels around the texture +coordinate in the level N texture image.  The four texels are +linearly weighted to compute the final texel value.  N is the level +of detail and is computed by the partial derivatives of the texture +coordinates with respect to the window coordinates.
    +
    +GL_LINEAR_MIPMAP_LINEAR samples four texels around the texture +coordinate in the level N texture image and four texels around the +texture coordinate in the level N+1 texture image.  The eight +texels are linearly weighted to compute the final texel value.  N +is the level of detail and is computed by the partial derivatives of the +texture coordinates with respect to the window coordinates.
    +
    +Filter modes other than GL_LINEAR and GL_NEAREST requires that the +texture have a complete set of mipmaps.  If the mipmap is +incomplete, it is as if texturing is disabled.
    + 
    +

    5.3.2 Texture Magnification

    +The texture magnification filter is set with the glTexParameteri command +by setting target to +GL_TEXTURE_2D, setting pname to +GL_TEXTURE_MAG_FILTER and setting value +to GL_NEAREST or GL_LINEAR.
    +
    +GL_NEAREST samples the texel nearest the texture coordinate in the +level 0 texture image.
    +
    +GL_LINEAR samples the four texels around the texture coordinate in the +level 0 texture image.  The four texels are linearly weighted to +compute the final texel value.
    +
    +

    5.4 Texture Application

    +The sampled texture value is combined with the incoming fragment color +to produce a new fragment color.  The fragment and texture colors +are combined according to the texture environment mode and the current +texture's base internal format.  The texture environment mode is +set with the command
    +
    +
    void +glTexEnvi(GLenum target, +GLenum pname, GLint value)
    +
    +
    +target must be GL_TEXTURE_ENV. + If pname is +GL_TEXTURE_ENV_MODE then value +must be one of GL_REPLACE, GL_MODULATE, GL_DECAL, or GL_BLEND.
    +
    +There is also a texture environment +color that can factor into texture application.  The texture +environment color can be set with the command
    +
    +
    void +glTexEnvfv(GLenum target, +GLenum pname, const GLfloat *value)
    +
    +
    +target must be GL_TEXTURE_ENV. + If pname is +GL_TEXTURE_ENV_COLOR then value must +point to an array of four values which specify the red, green, blue, +and alpha values of the texture environment color.  The values are +clamped to the range [0, 1].  The default color is (0, 0, 0, 0).
    +
    +The following table describes the arithmetic used for each combination +of environment mode and base internal format.  (Rf, Gf, Bf, Af) is +the incoming fragment color.  (Rt, Gt, Bt, At) is the sampled +texture color.  Lt is the sampled texture luminance.  'It' is the sampled texture +intensity.  (Rc, Gc, Bc, Ac) is the texture environment color. + (Rv, Gv, Bv, Av) is the resulting value.
    +

    +
    +
    +
    +

    5.5 Texture Objects

    +Texture objects encapsulate a set of texture images (mipmap) and +related state into a named object.  This facilitates use of +multiple textures in an application.  Texture objects are named +with GLuints (unsigned integers).  There is a default texture +object with the name/identifier zero which can never be deleted.
    +
    +

    5.5.1 Creating Texture Objects

    +A texture object is created by binding a new GLuint identifier to the +GL_TEXTURE_2D target with the command:
    +
    +
    void glBindTexture(GLenum target, GLuint textureID)
    +
    +
    +target must be GL_TEXTURE_2D. + textureID may be any +unsigned integer.  If textureID +does not name an existing texture object, a new texture object with that +ID will be created, initialized to the default state.  Whether the +ID is new or existed previously, that named texture object is bound as +the current texture object. + Subsequent glTexParameter andglTexImage2D calls will effect the +current texture object.
    +
    +

    5.5.2 Deleting Texture Objects

    +One or more texture objects may be deleted with the command:
    +
    +
    void glDeleteTextures(GLsizein, const GLuint *textureIDs)
    +
    +
    +textureIDs is an array of n texture IDs.  The named +texture objects will be deleted.  If the current texture object is +deleted the default texture object (number 0) will be bound as the +current texture object.
    +
    +

    5.5.3 Allocating Texture Object Identifiers

    +A list of new, unused texture IDs can be obtained by calling the command
    +
    +
    void glGenTextures(GLsizei n, GLuint *textureIDs)
    +
    +
    +An array of n unused texture +IDs will be returned in the textureIDs +array.
    +
    +
    +

    6. Per-fragment Operations

    +The fragments produced by rasterization are subjected to a number of +operations which either modify the fragment or test the fragment +(discarding the fragment if the test fails.)  This chapter +describes the per-fragment operations.  They are presented in the +order in which they're performed.  If a fragment fails a test it is +discarded and not subjected to subsequent tests or modifications.
    +
    +

    6.1 Scissor Test

    +The scissor test limits rendering to a 2-D rectangular region of the +framebuffer.  The command
    +
    +
    void glScissor(GLintx, GLint y, GLsizei width, GLsizei height)
    +
    +
    +defines a clipping region with the lower-left corner at (x, y) and the given width and height.  The scissor test is +enabled and disabled with the command glEnable(GL_SCISSOR_TEST) +and glDisable(GL_SCISSOR_TEST).
    +
    +If the incoming fragment's position is (xf, yf) +then the fragment will pass the test if x <= xf < x + width and y <= yf < y + height.  Otherwise, the +fragment is discarded.
    +
    +If width or height is less than zero the error +GL_INVALID_VALUE is raised.  The default scissor rectangle bounds +are (0, 0, w, h) where w is the initial window width and h is the +initial window height.  The scissor test is disabled by default.
    +
    +

    6.2 Alpha Test

    +The alpha test compares the fragment's alpha value against a reference +value and discards the fragment if the comparison fails.  The test +is specified by the command
    +
    +
    void glAlphaFunc(GLenummode, GLclampf reference)
    +
    +
    +mode specifies an inequality +and reference specifies a value +to compare against.  The following table lists all possible +modes and the +corresponding test:
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    Comparison mode
    +     		The test passes if
    +
    GL_LESS
    +     		alpha < reference
    +
    GL_LEQUAL
    +     		alpha <= reference
    GL_GREATER
    +     		alpha > reference
    GL_GEQUAL
    +     		alpha >= reference
    GL_EQUAL
    +     		alpha == reference
    GL_NOTEQUAL
    +     		alpha != reference
    GL_NEVER
    +     		never pass
    +
    GL_ALWAYS
    +     		always passes
    +
    +
    +The reference parameter is +clamped to the range [0, 1].
    +
    +The alpha test is enabled and disabled with the commands glEnable(GL_ALPHA_TEST) and glDisable(GL_ALPHA_TEST).
    +
    +The default mode is GL_ALWAYS and the default reference value is 0.
    +
    +

    6.3 Stencil Test

    +The stencil buffer stores an N-bit integer value for each pixel in the +frame buffer.  The stencil test compares the stencil buffer value +at the fragment's position to a reference value and possibly discards +the fragment based on the outcome.  Furthermore, the stencil buffer +value may be updated or modified depending on the outcome.  If +there is no stencil buffer the stencil test is bypassed.
    +
    +Stenciling is controlled by the commands
    +
    +
    void glStencilFunc(GLenumfunc, GLint ref, GLuint mask)
    +void glStencilOp(GLenum stencilFail, GLenum depthTestFail, GLenum depthTestPass)
    +
    +
    +The glStencilFunc command controls the +stencil test while glStencilOp +command controls the how the stencil buffer is updated/modified after +the test.
    +
    +ref is clamped to the range [0, +2N-1] where N is the number of bits per stencil value in the +stencil buffer.
    +
    +The following table lists all possible values for the func parameter and when the stencil +test will pass.  Both the stencil buffer value and the stencil +reference value are bit-wise ANDed with the mask parameter before the test.
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    Stencil func value
    +     		Stencil test passes if
    +
    GL_LESS
    +     		(ref&mask) < (stencil buffer value +& mask)
    +
    GL_LEQUAL
    +     		(ref +& mask) <= (stencil +buffer value & mask)
    GL_GREATER
    +     		(ref +& mask) > (stencil +buffer value & mask)
    GL_GEQUAL
    +     		(ref +& mask) >= (stencil +buffer value & mask)
    GL_EQUAL
    +     		(ref +& mask) == (stencil +buffer value & mask)
    GL_NOTEQUAL
    +     		(ref +& mask) != (stencil +buffer value & mask)
    GL_NEVER
    +     		never passes
    +
    GL_ALWAYS
    +     		always passes
    +
    +
    +
    +If the stencil test passes, the fragment is passed to the next +per-fragment operation.  Otherwise, if the stencil test fails, the +value in the stencil buffer is updated according to the value of the stencilFail parameter to glStencilOp.
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    stencilFail +value
    +     		New stencil buffer value
    +
    GL_KEEP
    +     		originalValue
    +
    GL_ZERO
    +     		0
    +
    GL_INVERT
    +     		BitWiseInvert(originalValue) +i.e. ~originalValue
    +
    GL_REPLACE
    +     		ref
    +
    GL_INCR
    +     		originalValue + 1, clamped to +[0, 2N-1]
    GL_DECR
    +     		originalValue - 1, clamped to +[0, 2N-1]
    +
    +
    +The depthTestFail and depthTestPass parameters to glStencilOp are ignored.  Values +for func and stencilFail other than those listed +in the table will cause the error GL_INVALID_ENUM to be raised.
    +
    +The stencil test is enabled and disabled with the commands glEnable(GL_STENCIL_TEST) and glDisable(GL_STENCIL_TEST).
    +
    +The default stencil function is GL_ALWAYS.  The default stencil +reference value is 0.  The default stencil mask is ~0.  The +default stencil fail operation is GL_KEEP.
    +
    +Values written into the stencil buffer are masked with the command
    +
    +
    void glStencilMask(GLuintmask)
    +
    +
    +Only the bits which are set in mask +will be modified in the stencil buffer when written to.  If each +stencil buffer value has N bits, only the least significant N bits of mask are relevant.  The default +stencil mask is ~0.
    +
    +

    6.4 Blending and Logicop

    +Blending or a logic operation combines the incoming fragment color with +the destination frame buffer color according to a blending equation or +bit-wise Boolean logical operation.
    +
    +Blending is enabled and disabled with the commands glEnable(GL_BLEND) and glDisable(GL_BLEND).
    +
    +The logic operation is enabled and disabled with the commands glEnable(GL_LOGIC_OP) and glDisable(GL_LOGIC_OP).
    +
    +If both blending and the logic operation are enabled, the logic +operation has higher priority; blending is bypassed.
    +
    +

    6.4.1 Logic Op

    +The command
    +
    +
    void glLogicop(GLenummode)
    +
    +
    +Specifies the Boolean logic operation for combining the incoming +fragment color with the destination frame buffer color.  Both the +incoming fragment color and destination frame buffer colors are +interpreted as four-tuples of unsigned integer color components in the +range [0, 2N-1] where N is the number of bits per color +channel.  N may not be the same for all color channels.
    +
    +The following table lists all values for mode and the boolean arithmetic used +to combine the incoming fragment color value (src) with the destination framebuffer +color value (dst).  Standard ANSI C operators used.
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    GL_XOR
    +     		src ^ dst
    +
    GL_EQUIV
    +     		~(src ^ dst)
    +
    +
    +The fragment's color is replaced by the result of the logic operation.
    +
    +Specifying any value for mode +other than those listed in the above table will cause the error +GL_INVALID_ENUM to be raised.
    +
    +The default value for mode is +GL_COPY.  The logic operation is disabled by default.
    +
    +

    6.4.2 Blending

    +The command
    +
    +
    void glBlendFunc(GLenumsrcTerm, GLenum dstTerm)
    +
    +
    +specifies the terms of the blending equation.  If Cf = (Rf, Gf, +Bf, Af) is the incoming fragment color and Cb = (Rb, Gb, Bb, Ab) is the +frame buffer color, then the resulting color Cv = (Rv, Gv, Bv, Av) is +computed by:
    +
    +
    Cv = Cf * srcTerm + Cb * dstTerm
    +
    +
    +All possible values for srcTerm +and the corresponding arithmetic term are listed in the following table:
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +
    srcTerm
    +     		srcTermArithmetic

    +
    GL_ONE_MINUS_DST_ALPHA
    +     		(1-Ab, 1-Ab, 1-Ab, 1-Ab)
    +
    GL_SRC_ALPHA_SATURATE
    +     		(m, m, m, 1) where m = MIN(Af, +1-Ab)
    +
    +
    +All possible values for srcTerm +and the corresponding arithmetic term are listed in the following table:
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    +     		(Af, Af, Af, AF)
    +
    GL_ONE_MINUS_SRC_ALPHA
    +     		(1-Af, 1-Af, 1-Af, 1-Af)
    +
    GL_DST_ALPHA
    +     		(Ab, Ab, Ab, Ab)
    +
    GL_ONE_MINUS_DST_ALPHA
    +     		(1-Ab, 1-Ab, 1-Ab, 1-Ab)
    +
    +
    +The fragment's color is replaced by the result of the blending equation.
    +
    +Values for srcTerm and dstTerm other than those listed in +the table will cause the error GL_INVALID_ENUM to be raised.
    +
    +The default value for srcTerm +is GL_ONE.  The default value for dstTerm +is GL_ZERO.  Blending is disabled by default.
    +
    +

    6.5 Color Mask

    +The final fragment color is written into the current color buffer at +the end of the per-fragment operations.  Normally, all color +channels in the frame buffer are replaced with the final fragment color. + However, the command
    +
    +
    void glColorMask(GLbooleanredMask, GLboolean greenMask, GLboolean blueMask, GLboolean alphaMask)
    +
    +
    +allows selective writing to individual color channels.  If redMask is GL_TRUE then writing to +the red color channel is enabled, otherwise it's disabled. + Similarly, the green, blue and alpha channels can also be masked.
    +
    +Initially all four mask values are GL_TRUE.
    +
    +Color masking is not enabled/disabled with the glEnable/glDisable commands.
    +

    7. Frame Buffer Operations

    +The frame buffer is considered to be a two-dimensional array of pixels. + The frame buffer is also organized into layers or logical buffers. + There may be a front color buffer, back color buffer and stencil +buffer.  A double-buffered frame buffer has both a front color +buffer and back color buffer.  A single-buffered framebuffer only +has a front color buffer.  Each pixel in a color buffer has a red, +green and blue value and an optional alpha value.
    +
    +

    7.1 Clearing Buffers

    +Buffers are cleared (set to uniform values) with the command
    +
    +
    void glClear(GLbitfieldbuffers)
    +
    +
    +buffers is a bitmask for which +the value may be the bitwise-OR of the values GL_COLOR_BUFFER_BIT and +GL_STENCIL_BUFFER_BIT.  If the GL_COLOR_BUFFER_BIT bit is +specified, the current color buffer will be cleared.  If the +GL_STENCIL_BUFFER_BIT bit is specified, the stencil buffer will be +cleared.
    +
    +The current color buffer is specified with the command
    +
    +
    void glDrawBuffer(GLenum buffer)
    +
    +
    +buffer may be either GL_FRONT, +GL_BACK or GL_NONE.  GL_FRONT indicates that the front color buffer +will be modified by glClear and +any drawing command.  GL_BACK indicates that the back color buffer +will be modified by glClear and +any drawing command.  GL_NONE indicates that neither color buffer +will be modified by glClear or +any drawing command.  GL_BACK is only valid for double-buffered +frame buffers.
    +
    +The current scissor rectangle, set by the glScissor command, effects glClear, limiting +the clear to the scissor rectangle, if it's enabled.  Furthermore, only the color channels enabled by glColorMask will be effected by glClear(GL_COLOR_BUFFER_BIT). + Likewise, only the stencil bits enabled by glStencilMask will be effected by glClear(GL_STENCIL_BUFFER_BIT).
    +
    +The current clear color is set with the command
    +
    +
    void glClearColor(GLclampfred, GLclampf green, GLclampf blue, GLclampf alpha)
    +
    +
    +Subsequent calls to glClear +will use the color (red, green, blue, +alpha) to clear the front or back color buffers.
    +
    +The current stencil clear value is set with the command
    +
    +
    void glClearStencil(GLintclearValue)
    +
    +
    +If the stencil buffer is N bits deep, the least significant N bits of clearValue will be used to clear the +stencil buffer.
    +
    +
    +

    8. Other Features

    +

    8.1 Frame Buffer Readback

    +A rectangular region of pixels can be read from the frame buffer and +placed in client memory with the command
    +
    +
    void glReadPixels(GLintx, GLint y, GLsizei width, GLsizei height, GLenum format, GLenum type, GLvoid *data)
    +
    +
    +x and y specify the coordinate of the +lower-left corner of the region to read and width and height specify the size of the +rectangular region to read.  format +specifies the format of image data and must be either GL_RGB or +GL_RGBA.  type specify the +data type of the image data and must be either GL_UNSIGNED_BYTE or +GL_FLOAT.  Other values for format +or type will cause the error +GL_INVALID_ENUM to be raised.
    +
    +The framebuffer may contain 3-component colors (red, green, blue) or +4-component colors (red, green, blue, alpha).  If an alpha channel +is not present, alpha values default to 1.0.
    +
    +The frame buffer color components (red, green, blue, alpha) are either +converted to 8-bit unsigned integers in the range[0, 255] if type is GL_UNSIGNED_BYTE or +converted to floating point values in the range [0, 1] if type is GL_FLOAT.  The (red, +green, blue, alpha) tuples are then stored as GL_RGB triplets (by +dropping the alpha component) or GL_RGBA quadruples in client memory.
    +
    +Image data is packed into +client memory according to the pixel packing parameters which are set by +the command
    +
    +
    void glPixelStorei(GLenum pname, GLint value)
    +
    +
    +pname must be +GL_PACK_ROW_LENGTH.  value +indicates the stride (in pixels) between subsequent rows in the +destination image.  If GL_PACK_ROW_LENGTH is zero (the default) +then the width parameter to glReadPixels indicates the row stride.
    +
    +Pixel readback takes place as follows:
    +
    +
    if (GL_PACK_ROW_LENGTH == 0)
    +    rowLength = width;
    +else
    +    rowLength = GL_PACK_ROW_LENGTH
    +
    +if (format == GL_RGB) {
    +    for (i = 0; i < height; +i++) {
    +        for (j = 0; j < width; j++) {
    +            k = (i * +rowLength + j) * 3;
    +            data[k+0] = FrameBuffer(x + j, y + i).red;
    +            data[k+1] = FrameBuffer(x + j, y + i).green;
    +            data[k+2] = FrameBuffer(x + j, y + i).blue;
    +        }
    +    }
    +}
    +else {
    +    for (i = 0; i < height; +i++) {
    +        for (j = 0; j < width; j++) {
    +            k = (i * +rowLength + j) * 4;
    +            data[k+0] = FrameBuffer(x + j, y + i).red;
    +            data[k+1] = FrameBuffer(x + j, y + i).green;
    +            data[k+2] = FrameBuffer(x + j, y + i).blue;
    +            data[k+3] = FrameBuffer(x + j, y + i).alpha;
    +        }
    +    }
    +}
    +
    +
    +The function FrameBuffer(c, r) +returns the pixel in the frame buffer at column c of row r.  data is considered to be either a +GLubyte pointer or a GLfloat pointer, depending on the type parameter.  Similarly, the +FrameBuffer function returns either GLubyte values in the range [0, 255] +or GLfloat values in the range [0,1], depending on the type parameter.
    +
    +Pixels may be read from either the front or back color buffer. + The command
    +
    +
    void glReadBuffer(GLenumbuffer)
    +
    +
    +specifies the source for reading images with glReadPixels.  If buffer is GL_FRONT then front color +buffer is the source.  If buffer +is GL_BACK then the back color buffer is the source.  It is illegal +to specify GL_BACK when the color buffer is not double buffered. + Any invalid value for buffer +will raise the error GL_INVALID_ENUM.
    +
    +The default read source is GL_BACK if the frame buffer is double +buffered.  Otherwise, the default read source is GL_FRONT.
    +
    +

    8.2 Selection Mode

    +Selection mode is typically used to implement picking: determining which +primitive(s) are present at particular window positions.  The +command
    +
    +
    GLint glRenderMode(GLenummode)
    +
    +
    +is used to enable selection mode.  If mode is GL_SELECTION the graphics +library is put into selection mode.  If mode is GL_RENDER the graphic +library is put into normal rendering mode.  Any other value for mode will raise the error +GL_INVALID_ENUM.
    +
    +When in selection mode rendering commands will not effect the +framebuffer.  Instead, a record of the primitives that would have +been drawn is placed in the selection buffer.  The selection buffer +is specified with the command
    +
    +
    void glSelectionBuffer(GLsizein, GLuint *buffer)
    +
    +
    +buffer     is an array of n +unsigned integers.  No more than n +values will be placed in the buffer.
    +
    +The name stack is a stack +(LIFO) of unsigned integer names.  The following commands +manipulate the name stack:
    +
    +
    void glInitNames(void)
    +void glPushName(GLuint name)
    +void glPopName(void)
    +void glLoadName(GLuint name)
    +
    +
    +glInitNames resets the name +stack to an empty state.  glPushName pushes the given name value onto the stack.  glPopName pops the top name from the +stack.  glLoadName replaces the top value on +the stack with the specified name. + Stack underflow and overflow conditions cause the errors +GL_STACK_OVERFLOW and GL_STACK_UNDERFLOW to be raised.
    +
    +While in selection mode, primitives (points, lines, polygons) are +transformed and clip-tested normally.  Primitives which aren't +discarded by clipping cause the hit data to be updated.  The hit +data consists of three pieces of information: a hit flag, a minimum Z +value and a maximum Z value.  First, the hit flag is set. + Then, for each of the primitive's vertices, the vertex Z value is +compared to the minimum and maximum Z values.  The minimum Z value +is updated if the vertex's Z value is less than the minimum Z value. + The maximum Z value is updated if the vertex's Z value is greater +than the maximum Z value.
    +
    +When any of glInitNames, glPushName, glPopName, glLoadName or glRenderMode are called and the hit +flag is set, a hit record is +written to the selection buffer.
    +
    +A hit record consists of a sequence of unsigned integers.  The +first value is the size of the name stack.  The second value is the +minimum Z value multiplied by 232-1.  The third value is +the maximum Z value multiplied by 232-1.  The remaining +values are the values in the name stack, in bottom to top order. + The hit flag is cleared after a hit record is written to the +selection buffer.  Hit records are places sequentially into the +selection buffer until it is full or selection mode is terminated.
    +
    +Selection mode is terminated by calling glRenderMode(GL_RENDER).   The +return value of glRenderMode +will be -1 if the selection buffer overflowed.  Otherwise, the +return value will indicate the number of values written into the +selection buffer.
    +
    +

    8.3 Synchronization

    +The command
    +
    +
    void glFlush(void)
    +
    +
    +makes the graphics library to flush all pending graphics commands. + The command
    +

    +void glFinish(void)
    +
    +
    +makes the graphics library flush the command queue and wait until those +commands are completed.  glFlush +will not return until all previous graphics commands have been fully +completed.
    +
    +These commands are typically used to force completion of rendering to +the front color buffer.  Otherwise, rendering to the front color +buffer may not appear.  The swapbuffers +command (part of the window system binding library) does an implicit +flush before swapping the front and back color buffers.  The glReadPixels command also does an +implicit flush before reading pixel data from the frame buffer.
    +
    +

    9. State Queries

    +The current value of nearly all library state variables can be queried. + This chapter describes the commands used for querying the value of +state variables.
    +
    +

    9.1 General State Queries

    +The command
    +
    +

    +
    +
    +returns the value(s) of the state variable specified by pname.  The following table +lists all accepted values for pname +and a description of the value(s).  Specifying any other value for pname causes the error +GL_INVALID_ENUM to be raised.
    +
    + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + + +

    Appendix A: Issues

    +This appendix lists documentation and subset issues with their current +status.  For items which are still open, the documentation (above) +follows the recommended solution.
    +
    +

    A.1 Vertex Arrays

    +Should vertex arrays be supported?  Is there a performance +advantage?
    +
    +RESOLUTION: No, there isn't enough of a performance advantage to +justify them.
    +
    +

    A.2 Polygon Antialiasing and Edge Flags

    +Should edge flags be supported for antialiasing?
    +
    +Edge flags don't effect antialiasing, at least not normally.  A +number of approaches to antialiasing have been summarized in email.
    +
    +RECOMMENDATION: don't support edge flags.  They don't effect +polygon antialiasing.
    +
    +RESOLUTION: closed, as of 26 Feb 2003.
    +
    +

    A.3 glRasterPos vs. glWindowPos

    +Should glRasterPos and/or glWindowPos commands be supported?
    +
    +RESOLUTION: Closed: implement glRasterPos commands, but not glWindowPos +commands.
    +
    +

    A.4 GL_IBM_rasterpos_clip extension

    +Should the GL_IBM_rasterpos_clip extension be implemented?
    +
    +RESOLUTION:  No.  It's not required.
    +
    +

    A.5 Image Formats and Types

    +Which image formats and types should be supported for glTexImage2D and glReadPixels?
    +
    +OpenGL specifies a large +variety of image formats and data types.  Only a few are commonly +used.
    +
    +RECOMMENDATION:  we propose a subset:
    +
    +For glTexImage2D only allow type=GL_UNSIGNED_BYTE and format=GL_RGBA, GL_RGB, +GL_INTENSITY.   Only allow internalFormat +to be GL_RGBA, GL_RGB or GL_INTENSITY as well.  Basically, only +support image formats/types that are directly supported by the Radeon +hardware.  This will allow glTexImage2D +to basically just use memcpy to +copy texture images.
    +
    +For glReadPixels, only allow type = GL_UNSIGNED_BYTE or GL_FLOAT. + Only allow format = +GL_RGB or GL_RGBA.  This is just enough to support the OpenGL +conformance tests.
    +
    +RESOLUTION: open
    +
    +

    A.6 Texture Environment Modes

    +Which texture environment modes should be supported?  OpenGL 1.2 +has GL_REPLACE, GL_MODULATE, GL_DECAL and GL_BLEND.  GL_DECAL isn't +defined for all base internal texture formats.  GL_ADD is another +useful mode.  Perhaps drop GL_DECAL mode and add GL_ADD mode.
    +
    +RECOMMENDATION: implement the standard modes GL_REPLACE, GL_MODULATE, +GL_DECAL and GL_BLEND.
    +
    +RESOLUTION: open
    +
    +

    A.7 Truncated Mipmaps and LOD Control

    +Should we support the GL_TEXTURE_BASE_LEVEL, GL_TEXTURE_MAX_LEVEL, +GL_TEXTURE_MIN_LOD and GL_TEXTURE_MAX_LOD texture parameters?
    +
    +RECOMMENDATION:  We propose omitting these features at this time, +in the interest of simplifying the driver.
    +
    +RESOLUTION: open
    +
    +

    A.8 Texture Priorities and Residency

    +Should the subset support texture priorities via glPrioritizeTextures and the glAreTexturesResident command?
    +
    +RECOMMENDATION:  Few applications use these features and +functions.  We propose omitting them to simplify the driver.
    +
    +RESOLUTION: open
    +
    +

    A.9 Pixel Pack/Unpack Alignment Control

    +Should we support the GL_PACK_ALIGNMENT and GL_UNPACK_ALIGNMENT options?
    +
    +These are used to align pixel data addresses to 1, 2 and 4-byte +multiples for glBitmap, glTexImage2D +and glReadPixels.  These +aren't strictly needed since the user can provide a 1, 2 or 4-byte +aligned address and appropriate GL_PACK_ROW_LENGTH or +GL_UNPACK_ROW_LENGTH values instead.
    +
    +RECOMMENDATION:  We recommend omitting them to simplify the driver.
    +
    +RESOLUTION: open
    +
    +

    A.10 Pixel Pack/Unpack Skip Rows/Pixels Control

    +Should we support the GL_UNPACK_SKIP_PIXELS, GL_UNPACK_SKIP_ROWS, +GL_PACK_SKIP_PIXELS and GL_PACK_SKIP_ROWS options for pixel +unpacking/packing?
    +
    +These options aren't really needed since the user can adjust the start +address and GL_PACK/UNPACK_ROW_LENGTH parameters to achieve the same +effect.
    +
    +RECOMMENDATION:  omit these parameters.
    +
    +RESOLUTION: open
    +
    +

    A.11 Texture State Queries

    +Should we support the command glGetTexEnvi/fv, +glGetTexParameteri/fv and glGetTexLevelParameteri/fv?
    +
    +RECOMMENDATION:  No. They're seldom needed and their +implementation is several hundred lines of code in length.
    +
    +RESOLUTION:  open
    +
    +

    A.12 glGetIntegerv, glGetBooleanv and glGetDoublev

    +Should we support the commands glGetIntegerv, +glGetBooleanv and glGetDoublev +in addition to glGetFloatv?
    +
    +RECOMMENDATION:  Omit the boolean, integer and double-valued +functions. All state values which can be queried by these commands can +be expressed as floating point values and queried with glGetFloatv.  The +implementation of the other three commands involves many lines of code.
    +
    +RESOLUTION:  open
    +
    +

    A.13 glBitmap and Per-Fragment Operations

    +Should bitmaps rendered with glBitmap +be subjected to the per-fragment operations?
    +
    +If bitmaps are implemented with points it will be easy to implement the +per-fragment operations.  Otherwise, it could be difficult.
    +
    +RECOMMENDATION:  Implement glBitmap by drawing points/pixels with +the hardware.  This will make supporting the per-fragments +trivially easy.  Also, it makes portrait-mode display relatively +easy.
    +
    +RESOLUTION:  open
    +
    +

    A.14 Reduced gl.h Header File

    +Should we produce a reduced gl.h header file which only defines the +tokens and functions which are implemented by the subset?
    +
    +RECOMMENDATION: yes.  It would be a useful reference to +programmers to quickly determine which functions and tokens are +supported.
    +
    +RESOLUTION: open
    +
    +

    A.15 glPolygonMode

    +Is glPolygonMode needed?
    +
    +RECOMMENDATION: No.  Omit it.
    +
    +RESOLUTION: closed, as of 26 Feb 2003

    +Mesa was originally designed for Unix/X11 systems and is still best +supported on those systems. All you need is an ANSI C compiler and the +X development environment to use Mesa. +

    + +

    +The DRI hardware drivers for the X.org server and XFree86 provide +hardware accelerated rendering for chips from ATI, Intel, Matrox, 3dfx +and others on Linux and FreeBSD. +

    + +

    +Drivers for other assorted platforms include: +the Amiga, Apple Macintosh, BeOS, NeXT, OS/2, MS-DOS, VMS, Windows +9x/NT, and Direct3D. +

    Xlib Software Driver

    + +

    +Mesa's Xlib driver provides an emulation of the GLX interface so that +OpenGL programs which use the GLX API can render to any X display, even +those that don't support the GLX extension. +Effectively, the Xlib driver converts all OpenGL rendering into Xlib calls. +

    + +

    +The Xlib driver is the oldest Mesa driver and the most mature of Mesa's +software-only drivers. +

    + +

    +Since the Xlib driver emulates the GLX extension, it's not +totally conformant with a true GLX implementation. +The differences are fairly obscure, however. +

    + +

    +The unique features of the Xlib driver follows. +

    + + +

    X Visual Selection

    +

    +Mesa supports RGB(A) rendering into almost any X visual type and depth. +

    +

    +The glXChooseVisual function tries to choose the best X visual +for the given attribute list. However, if this doesn't suit your needs +you can force Mesa to use any X visual you want (any supported by your +X server that is) by setting the MESA_RGB_VISUAL and +MESA_CI_VISUAL +environment variables. +When an RGB visual is requested, glXChooseVisual +will first look if the MESA_RGB_VISUAL variable is defined. +If so, it will try to use the specified visual. +Similarly, when a color index visual is requested, glXChooseVisual will +look for the MESA_CI_VISUAL variable. +

    + +

    +The format of accepted values is: visual-class depth +

    +

    +Here are some examples: +

    +
    +   using csh:
+	% setenv MESA_RGB_VISUAL "TrueColor 8"		// 8-bit TrueColor
+	% setenv MESA_CI_VISUAL "PseudoColor 12"	// 12-bit PseudoColor
+	% setenv MESA_RGB_VISUAL "PseudoColor 8"	// 8-bit PseudoColor
+
+   using bash:
+	$ export MESA_RGB_VISUAL="TrueColor 8"
+	$ export MESA_CI_VISUAL="PseudoColor 12"
+	$ export MESA_RGB_VISUAL="PseudoColor 8"
+
    + + +

    Double Buffering

    +

    +Mesa can use either an X Pixmap or XImage as the back color buffer when in +double-buffer mode. +The default is to use an XImage. +The MESA_BACK_BUFFER environment variable can override this. +The valid values for MESA_BACK_BUFFER are: Pixmap and +XImage (only the first letter is checked, case doesn't matter). +

    + +

    +Using XImage is almost always faster than a Pixmap since it resides in +the application's address space. +When glXSwapBuffers() is called, XPutImage() or XShmPutImage() is used +to transfer the XImage to the on-screen window. +

    +

    +A Pixmap may be faster when doing remote rendering of a simple scene. +Some OpenGL features will be very slow with a Pixmap (for example, blending +will require a round-trip message for pixel readback.) +

    +

    +Experiment with the MESA_BACK_BUFFER variable to see which is faster +for your application. +

    + + +

    Colormaps

    +

    +When using Mesa directly or with GLX, it's up to the application +writer to create a window with an appropriate colormap. The GLUT +toolkit tris to minimize colormap flashing by sharing +colormaps when possible. Specifically, if the visual and depth of the +window matches that of the root window, the root window's colormap +will be shared by the Mesa window. Otherwise, a new, private colormap +will be allocated. +

    + +

    +When sharing the root colormap, Mesa may be unable to allocate the colors +it needs, resulting in poor color quality. This can happen when a +large number of colorcells in the root colormap are already allocated. +To prevent colormap sharing in GLUT, set the +MESA_PRIVATE_CMAP environment variable. The value isn't +significant. +

    + + +

    Gamma Correction

    +

    +To compensate for the nonlinear relationship between pixel values +and displayed intensities, there is a gamma correction feature in +Mesa. Some systems, such as Silicon Graphics, support gamma +correction in hardware (man gamma) so you won't need to use Mesa's +gamma facility. Other systems, however, may need gamma adjustment +to produce images which look correct. If you believe that +Mesa's images are too dim, read on. +

    + +

    +Gamma correction is controlled with the MESA_GAMMA environment +variable. Its value is of the form Gr Gg Gb or just G where +Gr is the red gamma value, Gg is the green gamma value, Gb is the +blue gamma value and G is one gamma value to use for all three +channels. Each value is a positive real number typically in the +range 1.0 to 2.5. +The defaults are all 1.0, effectively disabling gamma correction. +Examples: +

    +
    +	% export MESA_GAMMA="2.3 2.2 2.4"	// separate R,G,B values
+	% export MESA_GAMMA="2.0"		// same gamma for R,G,B
+
    +

    +The progs/demos/gamma.c program may help you to determine reasonable gamma +value for your display. With correct gamma values, the color intensities +displayed in the top row (drawn by dithering) should nearly match those +in the bottom row (drawn as grays). +

    + +

    +Alex De Bruyn reports that gamma values of 1.6, 1.6 and 1.9 work well +on HP displays using the HP-ColorRecovery technology. +

    + +

    +Mesa implements gamma correction with a lookup table which translates +a "linear" pixel value to a gamma-corrected pixel value. There is a +small performance penalty. Gamma correction only works in RGB mode. +Also be aware that pixel values read back from the frame buffer will +not be "un-corrected" so glReadPixels may not return the same data +drawn with glDrawPixels. +

    + +

    +For more information about gamma correction see: + +

    + + +

    Overlay Planes

    +

    +Hardware overlay planes are supported by the Xlib driver. To +determine if your X server has overlay support you can test for the +SERVER_OVERLAY_VISUALS property: +

    +
    +	xprop -root | grep SERVER_OVERLAY_VISUALS
+
    + + +

    HPCR Dithering

    +

    +If you set the MESA_HPCR_CLEAR environment variable then dithering +will be used when clearing the color buffer. This is only applicable +to HP systems with the HPCR (Color Recovery) feature. +This incurs a small performance penalty. +

    + + +

    Extensions

    +

    +The following MESA-specific extensions are implemented in the Xlib driver. +

    + +

    GLX_MESA_pixmap_colormap

    + +

    +This extension adds the GLX function: +

    +
    +    GLXPixmap glXCreateGLXPixmapMESA( Display *dpy, XVisualInfo *visual,
+                                      Pixmap pixmap, Colormap cmap )
+
    +

    +It is an alternative to the standard glXCreateGLXPixmap() function. +Since Mesa supports RGB rendering into any X visual, not just True- +Color or DirectColor, Mesa needs colormap information to convert RGB +values into pixel values. An X window carries this information but a +pixmap does not. This function associates a colormap to a GLX pixmap. +See the xdemos/glxpixmap.c file for an example of how to use this +extension. +

    +

    +GLX_MESA_pixmap_colormap specification +

    + + +

    GLX_MESA_release_buffers

    +

    +Mesa associates a set of ancillary (depth, accumulation, stencil and +alpha) buffers with each X window it draws into. These ancillary +buffers are allocated for each X window the first time the X window +is passed to glXMakeCurrent(). Mesa, however, can't detect when an +X window has been destroyed in order to free the ancillary buffers. +

    +

    +The best it can do is to check for recently destroyed windows whenever +the client calls the glXCreateContext() or glXDestroyContext() +functions. This may not be sufficient in all situations though. +

    +

    +The GLX_MESA_release_buffers extension allows a client to explicitly +deallocate the ancillary buffers by calling glxReleaseBuffersMESA() +just before an X window is destroyed. For example: +

    +
    +         #ifdef GLX_MESA_release_buffers
+            glXReleaseBuffersMESA( dpy, window );
+         #endif
+         XDestroyWindow( dpy, window );
+
    +

    +GLX_MESA_release_buffers specification +

    +

    +This extension was added in Mesa 2.0. +

    + +

    GLX_MESA_copy_sub_buffer

    +

    +This extension adds the glXCopySubBufferMESA() function. It works +like glXSwapBuffers() but only copies a sub-region of the window +instead of the whole window. +

    +

    +GLX_MESA_copy_sub_buffer specification +

    +

    +This extension was added in Mesa 2.6 +

    + +

It is backward-compatible with the current + OpenGL Utilities tesselator, and is intended to replace it. Here is + a summary of the major differences: + + - input contours can be intersecting, self-intersecting, or degenerate. + + - supports a choice of several winding rules for determining which parts + of the polygon are on the "interior". This makes it possible to do + CSG operations on polygons. + + - boundary extraction: instead of tesselating the polygon, returns a + set of closed contours which separate the interior from the exterior. + + - returns the output as a small number of triangle fans and strips, + rather than a list of independent triangles (when possible). + + - output is available as an explicit mesh (a quad-edge structure), + in addition to the normal callback interface. + + - the algorithm used is extremely robust. + + +The interface +------------- + + The tesselator state is maintained in a "tesselator object". + These are allocated and destroyed using + + GLUtesselator *gluNewTess( void ); + void gluDeleteTess( GLUtesselator *tess ); + + Several tesselator objects may be used simultaneously. + + Inputs + ------ + + The input contours are specified with the following routines: + + void gluTessBeginPolygon( GLUtesselator *tess ); + void gluTessBeginContour( GLUtesselator *tess ); + void gluTessVertex( GLUtesselator *tess, GLUcoord coords[3], void *data ); + void gluTessEndContour( GLUtesselator *tess ); + void gluTessEndPolygon( GLUtesselator *tess ); + + Within each BeginPolygon/EndPolygon pair, there can be zero or more + calls to BeginContour/EndContour. Within each contour, there are zero + or more calls to gluTessVertex(). The vertices specify a closed + contour (the last vertex of each contour is automatically linked to + the first). + + "coords" give the coordinates of the vertex in 3-space. For useful + results, all vertices should lie in some plane, since the vertices + are projected onto a plane before tesselation. "data" is a pointer + to a user-defined vertex structure, which typically contains other + information such as color, texture coordinates, normal, etc. It is + used to refer to the vertex during rendering. + + The library can be compiled in single- or double-precision; the type + GLUcoord represents either "float" or "double" accordingly. The GLU + version will be available in double-precision only.

The interior regions + are then tesselated, and the output is provided as callbacks. + + + Rendering Callbacks + ------------------- + + Callbacks are specified by the client using + + void gluTessCallback( GLUtesselator *tess, GLenum which, void (*fn)()); + + If "fn" is NULL, any previously defined callback is discarded. + + The callbacks used to provide output are: /* which == */ + + void begin( GLenum type ); /* GLU_TESS_BEGIN */ + void edgeFlag( GLboolean flag ); /* GLU_TESS_EDGE_FLAG */ + void vertex( void *data ); /* GLU_TESS_VERTEX */ + void end( void ); /* GLU_TESS_END */ + + Any of the callbacks may be left undefined; if so, the corresponding + information will not be supplied during rendering. + + The "begin" callback indicates the start of a primitive; type is one + of GL_TRIANGLE_STRIP, GL_TRIANGLE_FAN, or GL_TRIANGLES (but see the + notes on "boundary extraction" below). + + It is followed by any number of "vertex" callbacks, which supply the + vertices in the same order as expected by the corresponding glBegin() + call. After the last vertex of a given primitive, there is a callback + to "end". + + If the "edgeFlag" callback is provided, no triangle fans or strips + will be used. When edgeFlag is called, if "flag" is GL_TRUE then each + vertex which follows begins an edge which lies on the polygon boundary + (ie. an edge which separates an interior region from an exterior one). + If "flag" is GL_FALSE, each vertex which follows begins an edge which lies + in the polygon interior. "edgeFlag" will be called before the first + call to "vertex". + + Other Callbacks + --------------- + + void mesh( GLUmesh *mesh ); /* GLU_TESS_MESH */ + + - Returns an explicit mesh, represented using the quad-edge structure + (Guibas/Stolfi '85).

(Coordinate values must be small + enough so that two can be multiplied together without overflow.) + + GLU_TESS_NEED_COMBINE_CALLBACK says that the algorithm detected an + intersection between two edges in the input data, and the "combine" + callback (below) was not provided.

Possible values: + + GLU_TESS_WINDING_ODD + GLU_TESS_WINDING_NONZERO + GLU_TESS_WINDING_POSITIVE + GLU_TESS_WINDING_NEGATIVE + GLU_TESS_WINDING_ABS_GEQ_TWO + + The input contours parition the plane into regions. A winding + rule determines which of these regions are inside the polygon. + + For a single contour C, the winding number of a point x is simply + the signed number of revolutions we make around x as we travel + once around C (where CCW is positive). When there are several + contours, the individual winding numbers are summed. This + procedure associates a signed integer value with each point x in + the plane. Note that the winding number is the same for all + points in a single region. + + The winding rule classifies a region as "inside" if its winding + number belongs to the chosen category (odd, nonzero, positive, + negative, or absolute value of at least two). The current GLU + tesselator implements the "odd" rule. The "nonzero" rule is another + common way to define the interior. The other three rules are + useful for polygon CSG operations (see below). + + - GLU_TESS_BOUNDARY_ONLY. Values: TRUE (non-zero) or FALSE (zero). + + If TRUE, returns a set of closed contours which separate the + polygon interior and exterior (rather than a tesselation). + Exterior contours are oriented CCW with respect to the normal, + interior contours are oriented CW. The GLU_TESS_BEGIN callback + uses the type GL_LINE_LOOP for each contour. + + - GLU_TESS_TOLERANCE. Value: a real number between 0.0 and 1.0. + + This specifies a tolerance for merging features to reduce the size + of the output. For example, two vertices which are very close to + each other might be replaced by a single vertex. The tolerance + is multiplied by the largest coordinate magnitude of any input vertex; + this specifies the maximum distance that any feature can move as the + result of a single merge operation. If a single feature takes part + in several merge operations, the total distance moved could be larger. + + Feature merging is completely optional; the tolerance is only a hint. + The implementation is free to merge in some cases and not in others, + or to never merge features at all. The default tolerance is zero. + + The current implementation merges vertices only if they are exactly + coincident, regardless of the current tolerance. A vertex is + spliced into an edge only if the implementation is unable to + distinguish which side of the edge the vertex lies on. + Two edges are merged only when both endpoints are identical. + + + void gluTessNormal( GLUtesselator *tess, + GLUcoord x, GLUcoord y, GLUcoord z ) + + - Lets the user supply the polygon normal, if known. All input data + is projected into a plane perpendicular to the normal before + tesselation. All output triangles are oriented CCW with + respect to the normal (CW orientation can be obtained by + reversing the sign of the supplied normal). For example, if + you know that all polygons lie in the x-y plane, call + "gluTessNormal(tess, 0.0, 0.0, 1.0)" before rendering any polygons. + + - If the supplied normal is (0,0,0) (the default value), the + normal is determined as follows. The direction of the normal, + up to its sign, is found by fitting a plane to the vertices, + without regard to how the vertices are connected. It is + expected that the input data lies approximately in plane; + otherwise projection perpendicular to the computed normal may + substantially change the geometry. The sign of the normal is + chosen so that the sum of the signed areas of all input contours + is non-negative (where a CCW contour has positive area). + + - The supplied normal persists until it is changed by another + call to gluTessNormal. + + + Backward compatibility with the GLU tesselator + ---------------------------------------------- + + The preferred interface is the one described above. The following + routines are obsolete, and are provided only for backward compatibility: + + typedef GLUtesselator GLUtriangulatorObj; /* obsolete name */ + + void gluBeginPolygon( GLUtesselator *tess ); + void gluNextContour( GLUtesselator *tess, GLenum type ); + void gluEndPolygon( GLUtesselator *tess ); + + "type" is one of GLU_EXTERIOR, GLU_INTERIOR, GLU_CCW, GLU_CW, or + GLU_UNKNOWN. It is ignored by the current GLU tesselator. + + GLU_BEGIN, GLU_VERTEX, GLU_END, GLU_ERROR, and GLU_EDGE_FLAG are defined + as synonyms for GLU_TESS_BEGIN, GLU_TESS_VERTEX, GLU_TESS_END, + GLU_TESS_ERROR, and GLU_TESS_EDGE_FLAG. + + +Polygon CSG operations +---------------------- + + The features of the tesselator make it easy to find the union, difference, + or intersection of several polygons. + + First, assume that each polygon is defined so that the winding number + is 0 for each exterior region, and 1 for each interior region. Under + this model, CCW contours define the outer boundary of the polygon, and + CW contours define holes. Contours may be nested, but a nested + contour must be oriented oppositely from the contour that contains it. + + If the original polygons do not satisfy this description, they can be + converted to this form by first running the tesselator with the + GLU_TESS_BOUNDARY_ONLY property turned on. This returns a list of + contours satisfying the restriction above. By allocating two + tesselator objects, the callbacks from one tesselator can be fed + directly to the input of another. + + Given two or more polygons of the form above, CSG operations can be + implemented as follows: + + Union + Draw all the input contours as a single polygon. The winding number + of each resulting region is the number of original polygons + which cover it. The union can be extracted using the + GLU_TESS_WINDING_NONZERO or GLU_TESS_WINDING_POSITIVE winding rules. + Note that with the nonzero rule, we would get the same result if + all contour orientations were reversed. + + Intersection (two polygons at a time only) + Draw a single polygon using the contours from both input polygons. + Extract the result using GLU_TESS_WINDING_ABS_GEQ_TWO. (Since this + winding rule looks at the absolute value, reversing all contour + orientations does not change the result.) + + Difference + + Suppose we want to compute A \ (B union C union D). Draw a single + polygon consisting of the unmodified contours from A, followed by + the contours of B,C,D with the vertex order reversed (this changes + the winding number of the interior regions to -1). To extract the + result, use the GLU_TESS_WINDING_POSITIVE rule. + + If B,C,D are the result of a GLU_TESS_BOUNDARY_ONLY call, an + alternative to reversing the vertex order is to reverse the sign of + the supplied normal. For example in the x-y plane, call + gluTessNormal( tess, 0.0, 0.0, -1.0 ). + + +Performance +----------- + + The tesselator is not intended for immediate-mode rendering; when + possible the output should be cached in a user structure or display + list. General polygon tesselation is an inherently difficult problem, + especially given the goal of extreme robustness. + + The implementation makes an effort to output a small number of fans + and strips; this should improve the rendering performance when the + output is used in a display list. + + Single-contour input polygons are first tested to see whether they can + be rendered as a triangle fan with respect to the first vertex (to + avoid running the full decomposition algorithm on convex polygons). + Non-convex polygons may be rendered by this "fast path" as well, if + the algorithm gets lucky in its choice of a starting vertex. + + For best performance follow these guidelines: + + - supply the polygon normal, if available, using gluTessNormal(). + This represents about 10% of the computation time. For example, + if all polygons lie in the x-y plane, use gluTessNormal(tess,0,0,1). + + - render many polygons using the same tesselator object, rather than + allocating a new tesselator for each one. (In a multi-threaded, + multi-processor environment you may get better performance using + several tesselators.) + + +Comparison with the GLU tesselator +---------------------------------- + + On polygons which make it through the "fast path", the tesselator is + 3 to 5 times faster than the GLU tesselator. + + On polygons which don't make it through the fast path (but which don't + have self-intersections or degeneracies), it is about 2 times slower. + + On polygons with self-intersections or degeneraces, there is nothing + to compare against. + + The new tesselator generates many more fans and strips, reducing the + number of vertices that need to be sent to the hardware. + + Key to the statistics: + + vert number of input vertices on all contours + cntr number of input contours + tri number of triangles in all output primitives + strip number of triangle strips + fan number of triangle fans + ind number of independent triangles + ms number of milliseconds for tesselation + (on a 150MHz R4400 Indy) + + Convex polygon examples: + +New: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.0459 ms +Old: 3 vert, 1 cntr, 1 tri, 0 strip, 0 fan, 1 ind, 0.149 ms +New: 4 vert, 1 cntr, 2 tri, 0 strip, 1 fan, 0 ind, 0.0459 ms +Old: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.161 ms +New: 36 vert, 1 cntr, 34 tri, 0 strip, 1 fan, 0 ind, 0.153 ms +Old: 36 vert, 1 cntr, 34 tri, 0 strip, 0 fan, 34 ind, 0.621 ms + + Concave single-contour polygons: + +New: 5 vert, 1 cntr, 3 tri, 0 strip, 1 fan, 0 ind, 0.052 ms +Old: 5 vert, 1 cntr, 3 tri, 0 strip, 0 fan, 3 ind, 0.252 ms +New: 19 vert, 1 cntr, 17 tri, 2 strip, 2 fan, 1 ind, 0.911 ms +Old: 19 vert, 1 cntr, 17 tri, 0 strip, 0 fan, 17 ind, 0.529 ms +New: 151 vert, 1 cntr, 149 tri, 13 strip, 18 fan, 3 ind, 6.82 ms +Old: 151 vert, 1 cntr, 149 tri, 0 strip, 3 fan, 143 ind, 2.7 ms +New: 574 vert, 1 cntr, 572 tri, 59 strip, 54 fan, 11 ind, 26.6 ms +Old: 574 vert, 1 cntr, 572 tri, 0 strip, 31 fan, 499 ind, 12.4 ms + + Multiple contours, but no intersections: + +New: 7 vert, 2 cntr, 7 tri, 1 strip, 0 fan, 0 ind, 0.527 ms +Old: 7 vert, 2 cntr, 7 tri, 0 strip, 0 fan, 7 ind, 0.274 ms +New: 81 vert, 6 cntr, 89 tri, 9 strip, 7 fan, 6 ind, 3.88 ms +Old: 81 vert, 6 cntr, 89 tri, 0 strip, 13 fan, 61 ind, 2.2 ms +New: 391 vert, 19 cntr, 413 tri, 37 strip, 32 fan, 26 ind, 20.2 ms +Old: 391 vert, 19 cntr, 413 tri, 0 strip, 25 fan, 363 ind, 8.68 ms + + Self-intersecting and degenerate examples: + +Bowtie: 4 vert, 1 cntr, 2 tri, 0 strip, 0 fan, 2 ind, 0.483 ms +Star: 5 vert, 1 cntr, 5 tri, 0 strip, 0 fan, 5 ind, 0.91 ms +Random: 24 vert, 7 cntr, 46 tri, 2 strip, 12 fan, 7 ind, 5.32 ms +Font: 333 vert, 2 cntr, 331 tri, 32 strip, 16 fan, 3 ind, 14.1 ms +: 167 vert, 35 cntr, 254 tri, 8 strip, 56 fan, 52 ind, 46.3 ms +: 78 vert, 1 cntr, 2675 tri, 148 strip, 207 fan, 180 ind, 243 ms +: 12480 vert, 2 cntr, 12478 tri, 736 strip,1275 fan, 5 ind, 1010 ms diff --git a/mesalib/src/glu/sgi/libtess/alg-outline b/mesalib/src/glu/sgi/libtess/alg-outline new file mode 100644 index 000000000..33fd69728 --- /dev/null +++ b/mesalib/src/glu/sgi/libtess/alg-outline @@ -0,0 +1,228 @@ +/* +*/ + +This is only a very brief overview. There is quite a bit of +additional documentation in the source code itself. + + +Goals of robust tesselation +--------------------------- + +The tesselation algorithm is fundamentally a 2D algorithm. We +initially project all data into a plane; our goal is to robustly +tesselate the projected data. The same topological tesselation is +then applied to the input data. + +Topologically, the output should always be a tesselation. If the +input is even slightly non-planar, then some triangles will +necessarily be back-facing when viewed from some angles, but the goal +is to minimize this effect. + +The algorithm needs some capability of cleaning up the input data as +well as the numerical errors in its own calculations. One way to do +this is to specify a tolerance as defined above, and clean up the +input and output during the line sweep process. At the very least, +the algorithm must handle coincident vertices, vertices incident to an +edge, and coincident edges. + + +Phases of the algorithm +----------------------- + +1. Find the polygon normal N. +2. Project the vertex data onto a plane. It does not need to be + perpendicular to the normal, eg. we can project onto the plane + perpendicular to the coordinate axis whose dot product with N + is largest. +3. Using a line-sweep algorithm, partition the plane into x-monotone + regions. Any vertical line intersects an x-monotone region in + at most one interval. +4. Triangulate the x-monotone regions. +5. Group the triangles into strips and fans. + + +Finding the normal vector +------------------------- + +A common way to find a polygon normal is to compute the signed area +when the polygon is projected along the three coordinate axes. We +can't do this, since contours can have zero area without being +degenerate (eg. a bowtie). + +We fit a plane to the vertex data, ignoring how they are connected +into contours. Ideally this would be a least-squares fit; however for +our purpose the accuracy of the normal is not important. Instead we +find three vertices which are widely separated, and compute the normal +to the triangle they form. The vertices are chosen so that the +triangle has an area at least 1/sqrt(3) times the largest area of any +triangle formed using the input vertices. + +The contours do affect the orientation of the normal; after computing +the normal, we check that the sum of the signed contour areas is +non-negative, and reverse the normal if necessary. + + +Projecting the vertices +----------------------- + +We project the vertices onto a plane perpendicular to one of the three +coordinate axes. This helps numerical accuracy by removing a +transformation step between the original input data and the data +processed by the algorithm. The projection also compresses the input +data; the 2D distance between vertices after projection may be smaller +than the original 2D distance. However by choosing the coordinate +axis whose dot product with the normal is greatest, the compression +factor is at most 1/sqrt(3). + +Even though the *accuracy* of the normal is not that important (since +we are projecting perpendicular to a coordinate axis anyway), the +*robustness* of the computation is important. For example, if there +are many vertices which lie almost along a line, and one vertex V +which is well-separated from the line, then our normal computation +should involve V otherwise the results will be garbage. + +The advantage of projecting perpendicular to the polygon normal is +that computed intersection points will be as close as possible to +their ideal locations. To get this behavior, define TRUE_PROJECT. + + +The Line Sweep +-------------- + +There are three data structures: the mesh, the event queue, and the +edge dictionary. + +The mesh is a "quad-edge" data structure which records the topology of +the current decomposition; for details see the include file "mesh.h". + +The event queue simply holds all vertices (both original and computed +ones), organized so that we can quickly extract the vertex with the +minimum x-coord (and among those, the one with the minimum y-coord). + +The edge dictionary describes the current intersection of the sweep +line with the regions of the polygon. This is just an ordering of the +edges which intersect the sweep line, sorted by their current order of +intersection. For each pair of edges, we store some information about +the monotone region between them -- these are call "active regions" +(since they are crossed by the current sweep line). + +The basic algorithm is to sweep from left to right, processing each +vertex. The processed portion of the mesh (left of the sweep line) is +a planar decomposition. As we cross each vertex, we update the mesh +and the edge dictionary, then we check any newly adjacent pairs of +edges to see if they intersect. + +A vertex can have any number of edges. Vertices with many edges can +be created as vertices are merged and intersection points are +computed. For unprocessed vertices (right of the sweep line), these +edges are in no particular order around the vertex; for processed +vertices, the topological ordering should match the geometric ordering. + +The vertex processing happens in two phases: first we process are the +left-going edges (all these edges are currently in the edge +dictionary). This involves: + + - deleting the left-going edges from the dictionary; + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - marking any terminated regions (regions which lie between two left-going + edges) as either "inside" or "outside" according to their winding number. + +When there are no left-going edges, and the event vertex is in an +"interior" region, we need to add an edge (to split the region into +monotone pieces). To do this we simply join the event vertex to the +rightmost left endpoint of the upper or lower edge of the containing +region. + +Then we process the right-going edges. This involves: + + - inserting the edges in the edge dictionary; + - computing the winding number of any newly created active regions. + We can compute this incrementally using the winding of each edge + that we cross as we walk through the dictionary. + - relinking the mesh if necessary, so that the order of these edges around + the event vertex matches the order in the dictionary; + - checking any newly adjacent edges for intersection and/or merging. + +If there are no right-going edges, again we need to add one to split +the containing region into monotone pieces. In our case it is most +convenient to add an edge to the leftmost right endpoint of either +containing edge; however we may need to change this later (see the +code for details). + + +Invariants +---------- + +These are the most important invariants maintained during the sweep. +We define a function VertLeq(v1,v2) which defines the order in which +vertices cross the sweep line, and a function EdgeLeq(e1,e2; loc) +which says whether e1 is below e2 at the sweep event location "loc". +This function is defined only at sweep event locations which lie +between the rightmost left endpoint of {e1,e2}, and the leftmost right +endpoint of {e1,e2}. + +Invariants for the Edge Dictionary. + + - Each pair of adjacent edges e2=Succ(e1) satisfies EdgeLeq(e1,e2) + at any valid location of the sweep event. + - If EdgeLeq(e2,e1) as well (at any valid sweep event), then e1 and e2 + share a common endpoint. + - For each e in the dictionary, e->Dst has been processed but not e->Org. + - Each edge e satisfies VertLeq(e->Dst,event) && VertLeq(event,e->Org) + where "event" is the current sweep line event. + - No edge e has zero length. + - No two edges have identical left and right endpoints. + +Invariants for the Mesh (the processed portion). + + - The portion of the mesh left of the sweep line is a planar graph, + ie. there is *some* way to embed it in the plane. + - No processed edge has zero length. + - No two processed vertices have identical coordinates. + - Each "inside" region is monotone, ie. can be broken into two chains + of monotonically increasing vertices according to VertLeq(v1,v2) + - a non-invariant: these chains may intersect (slightly) due to + numerical errors, but this does not affect the algorithm's operation. + +Invariants for the Sweep. + + - If a vertex has any left-going edges, then these must be in the edge + dictionary at the time the vertex is processed. + - If an edge is marked "fixUpperEdge" (it is a temporary edge introduced + by ConnectRightVertex), then it is the only right-going edge from + its associated vertex. (This says that these edges exist only + when it is necessary.) + + +Robustness +---------- + +The key to the robustness of the algorithm is maintaining the +invariants above, especially the correct ordering of the edge +dictionary. We achieve this by: + + 1. Writing the numerical computations for maximum precision rather + than maximum speed. + + 2. Making no assumptions at all about the results of the edge + intersection calculations -- for sufficiently degenerate inputs, + the computed location is not much better than a random number. + + 3. When numerical errors violate the invariants, restore them + by making *topological* changes when necessary (ie. relinking + the mesh structure). + + +Triangulation and Grouping +-------------------------- + +We finish the line sweep before doing any triangulation. This is +because even after a monotone region is complete, there can be further +changes to its vertex data because of further vertex merging. + +After triangulating all monotone regions, we want to group the +triangles into fans and strips. We do this using a greedy approach. +The triangulation itself is not optimized to reduce the number of +primitives; we just try to get a reasonable decomposition of the +computed triangulation. diff --git a/mesalib/src/glu/sgi/libtess/dict-list.h b/mesalib/src/glu/sgi/libtess/dict-list.h new file mode 100644 index 000000000..11331a76e --- /dev/null +++ b/mesalib/src/glu/sgi/libtess/dict-list.h @@ -0,0 +1,100 @@ +/* + * SGI FREE SOFTWARE LICENSE B (Version 2.0, Sept. 18, 2008) + * Copyright (C) 1991-2000 Silicon Graphics, Inc.

Mantyla, An Introduction + * to Sold Modeling, Computer Science Press, Rockville, Maryland, 1988). + * + * The fundamental data structure is the "half-edge". Two half-edges + * go together to make an edge, but they point in opposite directions. + * Each half-edge has a pointer to its mate (the "symmetric" half-edge Sym), + * its origin vertex (Org), the face on its left side (Lface), and the + * adjacent half-edges in the CCW direction around the origin vertex + * (Onext) and around the left face (Lnext). There is also a "next" + * pointer for the global edge list (see below). + * + * The notation used for mesh navigation: + * Sym = the mate of a half-edge (same edge, but opposite direction) + * Onext = edge CCW around origin vertex (keep same origin) + * Dnext = edge CCW around destination vertex (keep same dest) + * Lnext = edge CCW around left face (dest becomes new origin) + * Rnext = edge CCW around right face (origin becomes new dest) + * + * "prev" means to substitute CW for CCW in the definitions above. + * + * The mesh keeps global lists of all vertices, faces, and edges, + * stored as doubly-linked circular lists with a dummy header node. + * The mesh stores pointers to these dummy headers (vHead, fHead, eHead). + * + * The circular edge list is special; since half-edges always occur + * in pairs (e and e->Sym), each half-edge stores a pointer in only + * one direction. Starting at eHead and following the e->next pointers + * will visit each *edge* once (ie. e or e->Sym, but not both). + * e->Sym stores a pointer in the opposite direction, thus it is + * always true that e->Sym->next->Sym->next == e. + * + * Each vertex has a pointer to next and previous vertices in the + * circular list, and a pointer to a half-edge with this vertex as + * the origin (NULL if this is the dummy header).

There is also + * a field "data" for client data. + * + * Note that what we call a "face" is really a loop; faces may consist + * of more than one loop (ie. not simply connected), but there is no + * record of this in the data structure. The mesh may consist of + * several disconnected regions, so it may not be possible to visit + * the entire mesh by starting at a half-edge and traversing the edge + * structure. + * + * The mesh does NOT support isolated vertices; a vertex is deleted along + * with its last edge. Similarly when two faces are merged, one of the + * faces is deleted (see __gl_meshDelete below). For mesh operations, + * all face (loop) and vertex pointers must not be NULL.

There are several cases: + * if (eDel->Lface != eDel->Rface), we join two loops into one; the loop + * eDel->Lface is deleted. Otherwise, we are splitting one loop into two; + * the newly created loop will contain eDel->Dst. If the deletion of eDel + * would create isolated vertices, those are deleted as well. + * + * ********************** Other Edge Operations ************************** + * + * __gl_meshAddEdgeVertex( eOrg ) creates a new edge eNew such that + * eNew == eOrg->Lnext, and eNew->Dst is a newly created vertex. + * eOrg and eNew will have the same left face. + * + * __gl_meshSplitEdge( eOrg ) splits eOrg into two edges eOrg and eNew, + * such that eNew == eOrg->Lnext. The new vertex is eOrg->Dst == eNew->Org. + * eOrg and eNew will have the same left face. + * + * __gl_meshConnect( eOrg, eDst ) creates a new edge from eOrg->Dst + * to eDst->Org, and returns the corresponding half-edge eNew. + * If eOrg->Lface == eDst->Lface, this splits one loop into two, + * and the newly created loop is eNew->Lface. Otherwise, two disjoint + * loops are merged into one, and the loop eDst->Lface is destroyed. + * + * ************************ Other Operations ***************************** + * + * __gl_meshNewMesh() creates a new mesh with no edges, no vertices, + * and no loops (what we usually call a "face"). + * + * __gl_meshUnion( mesh1, mesh2 ) forms the union of all structures in + * both meshes, and returns the new mesh (the old meshes are destroyed). + * + * __gl_meshDeleteMesh( mesh ) will free all storage for any valid mesh. + * + * __gl_meshZapFace( fZap ) destroys a face and removes it from the + * global face list.
