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 glapi_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
-

Development Notes

+ + +

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 glapi_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
+
+ + +

Mesa EGL

- -

The current version of EGL in Mesa implements EGL 1.4. More information -about EGL can be found at - -http://www.khronos.org/egl/.

- -

The Mesa's implementation of EGL uses a driver architecture. The main -library (libEGL) is window system neutral. It provides the EGL -API entry points and helper functions for use by the drivers. Drivers are -dynamically loaded by the main library and most of the EGL API calls are -directly dispatched to the drivers.

- -

The driver in use decides the window system to support. For drivers that -support hardware rendering, there are usually multiple drivers supporting the -same window system. Each one of of them supports a certain range of graphics -cards.

- -

Build EGL

- -
    -
  1. -

    Run configure with the desired state trackers and enable -the Gallium driver for your hardware. For example

    - -
    -  $ ./configure --enable-gles-overlay --with-state-trackers=egl,vega --enable-gallium-intel
-
    - -

    The main library and OpenGL is enabled by default. The first option enables -OpenGL ES 1.x and 2.x. The egl state -tracker is needed by a number of EGL drivers. EGL drivers will be covered -later. The vega state tracker provides OpenVG -1.x.

    -
    2. - -
  2. Build and install Mesa as usual.
    3. -
- -

In the given example, it will build and install libEGL, -libGL, libGLESv1_CM, libGLESv2, -libOpenVG, and one or more EGL drivers.

- -

Configure Options

- -

There are several options that control the build of EGL at configuration -time

- -
    -
  • --enable-egl - -

    By default, EGL is enabled. When disabled, the main library and the drivers -will not be built.

    - -
    • - -
  • --with-egl-driver-dir - -

    The directory EGL drivers should be installed to. If not specified, EGL -drivers will be installed to ${libdir}/egl.

    - -
    • - -
  • --with-egl-platforms - -

    List the platforms (window systems) to support. Its argument is a comma -seprated string such as --with-egl-platforms=x11,drm. It decides -the platforms a driver may support. The first listed platform is also used by -the main library to decide the native platform: the platform the EGL native -types such as EGLNativeDisplayType or -EGLNativeWindowType defined for.

    - -

    The available platforms are x11, drm, -fbdev, and gdi. The gdi platform can -only be built with SCons.

    - -
    • - -
  • --with-state-trackers - -

    The argument is a comma separated string. It is usually used to specify the -rendering APIs, such as OpenVG, to build. But it is also used to specify -egl state tracker that egl_gallium depends on.

    - -
    • - -
  • --enable-gles-overlay - -

    OpenGL and OpenGL ES are not controlled by ---with-state-trackers. OpenGL is always built. To build OpenGL -ES, this option must be explicitly given.

    - -
    • - -
  • --enable-gles1 and --enable-gles2 - -

    Unlike --enable-gles-overlay, which builds one library for each -rendering API, these options enable OpenGL ES support in OpenGL. The result is -one big library that supports multiple APIs.

    - -
    • - -
- -

Use EGL

- -

Demos

- -

There are demos for the client APIs supported by EGL. They can be found in -mesa/demos repository.

- -

Environment Variables

- -

There are several environment variables that control the behavior of EGL at -runtime

- -
    -
  • EGL_DRIVERS_PATH - -

    By default, the main library will look for drivers in the directory where -the drivers are installed to. This variable specifies a list of -colon-separated directories where the main library will look for drivers, in -addition to the default directory. This variable is ignored for setuid/setgid -binaries.

    - -
    • - -
  • EGL_DRIVER - -

    This variable specifies a full path to an EGL driver and it forces the -specified EGL driver to be loaded. It comes in handy when one wants to test a -specific driver. This variable is ignored for setuid/setgid binaries.

    - -

    egl_gallium dynamically loads hardware drivers and client API -modules found in EGL_DRIVERS_PATH. Thus, specifying this variable -alone is not sufficient for egl_gallium for uninstalled build.

    - -
    • - -
  • EGL_PLATFORM - -

    This variable specifies the native platform. The valid values are the same -as those for --with-egl-platforms. When the variable is not set, -the main library uses the first platform listed in ---with-egl-platforms as the native platform

    - -
    • - -
  • EGL_LOG_LEVEL - -

    This changes the log level of the main library and the drivers. The valid -values are: debug, info, warning, and -fatal.

    - -
    • - -
  • EGL_SOFTWARE - -

    For drivers that support both hardware and software rendering, setting this -variable to true forces the use of software rendering.

    - -
    • -
- -

EGL Drivers

- -
    -
  • egl_gallium - -

    This driver is based on Gallium3D. It supports all rendering APIs and -hardwares supported by Gallium3D. It is the only driver that supports OpenVG. -The supported platforms are X11, KMS, FBDEV, and GDI.

    - -
    • - -
  • egl_glx - -

    This driver provides a wrapper to GLX. It uses exclusively GLX to implement -the EGL API. It supports both direct and indirect rendering when the GLX does. -It is accelerated when the GLX is. As such, it cannot provide functions that -is not available in GLX or GLX extensions.

    -
    • - -
  • egl_dri2 - -

    This driver supports the X Window System as its window system. It functions -as a DRI2 driver loader. Unlike egl_glx, it has no dependency on -libGL. It talks to the X server directly using DRI2 protocol.

    - -
    • -
  • egl_dri - -

    This driver lacks maintenance and does not build. It is similiar -to egl_dri2 in that it functions as a DRI(1) driver loader. But -unlike egl_dri2, it supports Linux framebuffer devices as its -window system and supports EGL_MESA_screen_surface extension. As DRI1 drivers -are phasing out, it might eventually be replaced by egl_dri2.

    - -
    • -
- -

Developers

- -

The sources of the main library and the classic drivers can be found at -src/egl/. The sources of the egl state tracker can -be found at src/gallium/state_trackers/egl/.

- -

The suggested way to learn to write a EGL driver is to see how other drivers -are written. egl_glx should be a good reference. It works in any -environment that has GLX support, and it is simpler than most drivers.

- -

Lifetime of Display Resources

- -

Contexts and surfaces are examples of display resources. They might live -longer than the display that creates them.

- -

In EGL, when a display is terminated through eglTerminate, all -display resources should be destroyed. Similarly, when a thread is released -throught eglReleaseThread, all current display resources should be -released. Another way to destory or release resources is through functions -such as eglDestroySurface or eglMakeCurrent.

- -

When a resource that is current to some thread is destroyed, the resource -should not be destroyed immediately. EGL requires the resource to live until -it is no longer current. A driver usually calls -eglIs<Resource>Bound to check if a resource is bound -(current) to any thread in the destroy callbacks. If it is still bound, the -resource is not destroyed.

- -

The main library will mark destroyed current resources as unlinked. In a -driver's MakeCurrent callback, -eglIs<Resource>Linked can then be called to check if a newly -released resource is linked to a display. If it is not, the last reference to -the resource is removed and the driver should destroy the resource. But it -should be careful here because MakeCurrent might be called with an -uninitialized display.

- -

This is the only mechanism provided by the main library to help manage the -resources. The drivers are responsible to the correct behavior as defined by -EGL.

- -

EGL_RENDER_BUFFER

- -

In EGL, the color buffer a context should try to render to is decided by the -binding surface. It should try to render to the front buffer if the binding -surface has EGL_RENDER_BUFFER set to -EGL_SINGLE_BUFFER; If the same context is later bound to a -surface with EGL_RENDER_BUFFER set to -EGL_BACK_BUFFER, the context should try to render to the back -buffer. However, the context is allowed to make the final decision as to which -color buffer it wants to or is able to render to.

- -

For pbuffer surfaces, the render buffer is always -EGL_BACK_BUFFER. And for pixmap surfaces, the render buffer is -always EGL_SINGLE_BUFFER. Unlike window surfaces, EGL spec -requires their EGL_RENDER_BUFFER values to be honored. As a -result, a driver should never set EGL_PIXMAP_BIT or -EGL_PBUFFER_BIT bits of a config if the contexts created with the -config won't be able to honor the EGL_RENDER_BUFFER of pixmap or -pbuffer surfaces.

- -

It should also be noted that pixmap and pbuffer surfaces are assumed to be -single-buffered, in that eglSwapBuffers has no effect on them. It -is desirable that a driver allocates a private color buffer for each pbuffer -surface created. If the window system the driver supports has native pbuffers, -or if the native pixmaps have more than one color buffers, the driver should -carefully attach the native color buffers to the EGL surfaces, re-route them if -required.

- -

There is no defined behavior as to, for example, how -glDrawBuffer interacts with EGL_RENDER_BUFFER. Right -now, it is desired that the draw buffer in a client API be fixed for pixmap and -pbuffer surfaces. Therefore, the driver is responsible to guarantee that the -client API renders to the specified render buffer for pixmap and pbuffer -surfaces.

- -

EGLDisplay Mutex

- -The EGLDisplay will be locked before calling any of the dispatch -functions (well, except for GetProcAddress which does not take an -EGLDisplay). This guarantees that the same dispatch function will -not be called with the sample display at the same time. If a driver has access -to an EGLDisplay without going through the EGL APIs, the driver -should as well lock the display before using it. - -

TODOs

- -
    -
  • Pass the conformance tests
    • -
  • Reference counting in main library?
    • -
  • Mixed use of OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is supported. But -which one of libGL.so, libGLESv1_CM.so, and -libGLESv2.so should an application link to? Bad things may happen -when, say, an application is linked to libGLESv2.so and -libcairo, which is linked to libGL.so instead.

    Run configure with the desired client APIs and enable +the driver for your hardware. For example

    + +
    +  $ ./configure --enable-gles2 --enable-openvg --enable-gallium-nouveau

    + +
    • + +
  • --enable-gles1 and --enable-gles2 + +

    These options enable OpenGL ES support in OpenGL. The result is one big +internal library that supports multiple APIs.

    + +
    • + +
  • --enable-gles-overlay + +

    This option enables OpenGL ES as separate internal libraries. This is an +alternative approach to enable OpenGL ES.

    + +

    This is only supported by egl_gallium. For systems using DRI +drivers, --enable-gles1 and --enable-gles2 are +suggested instead as all drivers will benefit.

    + +
    • + +
  • --enable-openvg + +

    OpenVG must be explicitly enabled by this option.

    + +
    • + +
  • --enable-gallium-egl + +

    + +

    Extensions like EGL_MESA_drm_display define new functions to +create displays for non-native platforms. These extensions are usually used by +applications that support non-native platforms. Setting this variable is +probably required only for some of the demos found in mesa/demo repository.

    + +
    • + +
  • EGL_LOG_LEVEL + +

    This changes the log level of the main library and the drivers. The valid +values are: debug, info, warning, and +fatal.

  • egl_dri2 + +

    This driver supports both x11 and drm platforms. +It functions as a DRI driver loader. For x11 support, it talks to +the X server directly using (XCB-)DRI2 protocol.

    + +

    This driver can share DRI drivers with libGL.

Packaging

+ +

The ABI between the main library and its drivers are not stable. Nor is +there a plan to stabilize it at the moment. Of the EGL drivers, +egl_gallium has its own hardware drivers and client API modules. +They are considered internal to egl_gallium and there is also no +stable ABI between them. These should be kept in mind when packaging for +distribution.

+ +

Generally, egl_dri2 is preferred over egl_gallium +when the system already has DRI drivers. As egl_gallium is loaded +before egl_dri2 when both are available, egl_gallium +may either be disabled with --disable-gallium-egl or packaged +separately.

+ +

If a driver has access +to an EGLDisplay without going through the EGL APIs, the driver +should as well lock the display before using it. + +

TODOs

+ +
    +
  • Pass the conformance tests
    • +
  • Mixed use of OpenGL, OpenGL ES 1.1, and OpenGL ES 2.0 is supported. But +which one of libGL.so, libGLESv1_CM.so, and +libGLESv2.so should an application link to? Bad things may happen +when, say, an application is linked to libGLESv2.so and +libcairo, which is linked to libGL.so instead.

OpenGL client applications should link with the +-lGL option to use it. + +libGL.so serves two primary functions: GLX protocol generation for indirect +rendering and loading/management of hardware drivers for direct rendering. + +When libGL.so initializes itself it uses the DRI to determine the +appropriate hardware driver for each screen on the local X display. +The hardware drivers are expected to be in the /usr/X11R6/lib/modules/dri/ +directory. Drivers are named with the convention _dri.so where + is a driver such as "tdfx", "i810", "gamma", etc. + +The LIBGL_DRIVERS_DIR environment variable may be used to specify a +different DRI modules directory, overriding /usr/X11R6/lib/modules/dri/. +This environment variable is ignored in setuid programs for security +reasons. + +When libGL.so is unable to locate appropriate hardware drivers it will +fall back to using indirect GLX rendering. + +To aid in solving problems, libGL.so will print diagnostic messages to +stderr if the LIBGL_DEBUG environment variable is defined. + +libGL.so is thread safe. The overhead of thread safety for common, +single-thread clients is negligible. However, the overhead of thread +safety for multi-threaded clients is significant. Each GL API call +requires two calls to pthread_get_specific() which can noticably +impact performance. Warning: libGL.so is thread safe but individual +DRI drivers may not be. Please consult the documentation for a driver +to learn if it is thread safe. + + + +Indirect Rendering + +You can force indirect rendering mode by setting the LIBGL_ALWAYS_INDIRECT +environment variable. Hardware acceleration will not be used. + + + +libGL.so Extensibility + +libGL.so is designed to be extended without upgrading. That is, +drivers may install new OpenGL extension functions into libGL.so +without requiring libGL.so to be replaced. Clients of libGL.so should +use the glXGetProcAddressEXT() function to obtain the address of +functions by name. For more details of GLX_ARB_get_proc_address see +http://oss.sgi.com/projects/ogl-sample/registry/ARB/get_proc_address.spec + +libGL.so is also designed with flexibility such that it may be used +with many generations of hardware drivers to come. + + + + +Driver Developer's Guide +------------------------ + +This section describes the requirements to make an XFree86 4.0 +libGL.so-compatible hardware driver. It is not intended for end +users of libGL.so. + + +XFree86 source files + +libGL.so is built inside XFree86 with sources found in xc/lib/GL/. +Specifically, libGL.so is built from: + + xc/lib/GL/glx/*.c + xc/lib/dri/XF86dri.c + xc/lib/dri/dri_glx.c + xc/lib/GL/mesa/src/glapi.c + xc/lib/GL/mesa/src/glapitemp.h + xc/lib/GL/mesa/src/glapitable.h + xc/lib/GL/mesa/src/glapioffsets.h + xc/lib/GL/mesa/src/glapinoop.c + xc/lib/GL/mesa/src/glheader.h + xc/lib/GL/mesa/src/glthread.c + xc/lib/GL/mesa/src/glthread.h + xc/lib/GL/mesa/src/X86/glapi_x86.S + xc/lib/GL/mesa/src/X86/assyntax.h + +Understand that the mesa/src/gl*.[ch] files are not tied to Mesa. They +have no dependencies on the rest of Mesa and are designed to be reusable +in a number of projects. + +The glapi_x86.X and assyntax.h files implement x86-optimized dispatch +of GL functions. They are not required; C-based dispatch can be used +instead, with a slight performance penalty. + + + +Driver loading and binding + +When libGL.so initializes itself (via the __glXInitialize function) a +call is made to driCreateDisplay(). This function uses DRI facilities +to determine the driver file appropriate for each screen on the local +display. Each screen's driver is then opened with dlopen() and asked +for its __driCreateScreen() function. The pointers to the __driCreateScreen() +functions are kept in an array, indexed by screen number, in the +__DRIdisplayRec struct. + +When a driver's __driCreateScreen() function is called, it must initialize +a __DRIscreenRec struct. This struct acts as the root of a tree of +function pointers which are called to create and destroy contexts and +drawables and perform all the operations needed by the GLX interface. +See the xc/lib/GL/glx/glxclient.h file for details. + + + +Dynamic Extension Function Registration + +In order to provide forward compatibility with future drivers, libGL.so +allows drivers to register new OpenGL extension functions which weren't +known when libGL.so was built. + +The register_extensions() function in xc/lib/GL/dri/dri_glx.c is called +as soon as libGL.so is loaded. This is done with gcc's constructor +attribute. This mechanism will likely have to be changed for other compilers. + +register_extensions() loops over all local displays and screens, determines +the DRI driver for each, and calls the driver's __driRegisterExtensions() +function, if present. + +The __driRegisterExtensions() function can add new entrypoints to libGL +by calling: + + GLboolean _glapi_add_entrypoint(const char *funcName, GLuint offset) + +The parameters are the name of the function (such as "glFoobarEXT") and the +offset of the dispatch slot in the API dispatch table. The return value +indicates success (GL_TRUE) or failure (GL_FALSE). + +_glapi_add_entrypoint() will synthesize entrypoint code in assembly +language. Assembly languages is required since parameter passing +can't be handled correctly using a C-based solution. + +The address of the new entrypoint is obtained by calling the +glXGetProcAddressARB() function. + +The dispatch offset number MUST be a number allocated by SGI in the same +manner in which new GL_* constants are allocated. Using an arbitrary +offset number will result in many problems. + + + +Dispatch Management + +When a GL context is made current, the driver must install its dispatch +table as the current dispatch table. This is done by calling + + void _glapi_set_dispatch(struct _glapi_table *dispatch); + +This will install the named dispatch table for the calling thread. +The current dispatch table for a thread can be obtained by calling + + struct _glapi_table *_glapi_get_dispatch(void); + +For higher performance in the common single-thread case, the global +variable _glapi_Dispatch will point to the current dispatch table. +This variable will be NULL when in multi-thread mode. + + + +Context Management + +libGL.so uses the XFree86 xthreads package to manage a thread-specific +current context pointer. See __glXGet/SetCurrentContext() in glext.c + +Drivers may use the _glapi_set/get_context() functions to maintain +a private thread-specific context pointer. + diff --git a/mesalib/docs/mesa.css b/mesalib/docs/mesa.css new file mode 100644 index 000000000..8e4944e44 --- /dev/null +++ b/mesalib/docs/mesa.css @@ -0,0 +1,33 @@ +/* Mesa CSS */ +body { + background-color: #ffffff; + font: 14px 'Lucida Grande', Geneva, Arial, Verdana, sans-serif; + color: black; + link: #111188; +} + +h1 { + font: 24px 'Lucida Grande', Geneva, Arial, Verdana, sans-serif; + font-weight: bold; + color: black; +} + +h2 { + font: 18px 'Lucida Grande', Geneva, Arial, Verdana, sans-serif, bold; + font-weight: bold; + color: black; +} + +code { + font-family: monospace; + font-size: 10pt; + color: black; +} + + +pre { + /*font-family: monospace;*/ + font-size: 10pt; + /*color: black;*/ +} + diff --git a/mesalib/docs/news.html b/mesalib/docs/news.html index b3fb8b556..1bdef71de 100644 --- a/mesalib/docs/news.html +++ b/mesalib/docs/news.html @@ -1,1302 +1,1310 @@ - - -Mesa News - - - - - - - -

I'm pleased to announce that I've accepted a position with Precision Insight, -Inc. effective October, 1999. I'll be leaving Avid Technology in September.

-

I've been working on Mesa in my spare time for over five years. With Precision -Insight I now have the opportunity to devote my full attention to advancing Mesa -and OpenGL on Linux.

-

While I'll be focused on Linux, the X Window System, and hardware acceleration, -my work will continue to be open sourced and available to any other programmers who -may want to contribute to it, or use it for other projects or platforms

-

PS: I'm going to be traveling until Sep 6 and won't be reading email until then.

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.

I'm pleased to announce that I've accepted a position with Precision Insight, +Inc. effective October, 1999. I'll be leaving Avid Technology in September.

+

I've been working on Mesa in my spare time for over five years. With Precision +Insight I now have the opportunity to devote my full attention to advancing Mesa +and OpenGL on Linux.

+

While I'll be focused on Linux, the X Window System, and hardware acceleration, +my work will continue to be open sourced and available to any other programmers who +may want to contribute to it, or use it for other projects or platforms

+

PS: I'm going to be traveling until Sep 6 and won't be reading email until then.

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. -Please refer to Mesa EGL for more information about EGL. -

- - -

Building the library

-
    -
  1. Build Mesa3D with Gallium3D. Any build that builds Gallium3D libraries, EGL, and Gallium EGL drivers 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: -
-  $ ./configure --with-state-trackers=egl,vega --enable-gallium-intel
-  $ make
-  $ make install
-
- -

OpenVG Demos

- -

-To build the OpenVG demos: -

-
-  cd progs/openvg
-  make
-
-

-To run a demo: -

-
-  cd openvg/demos
-  ./lion

+ + +

Building the library

+
    +
  1. Run configure with --enable-openvg. If you do +not need OpenGL, you can add --disable-opengl to save the +compilation time.
    2. + +
  2. Build and install Mesa as usual.
    3. +
+ +

Sample build

+A sample build looks as follows: +
+  $ ./configure --disable-opengl --enable-openvg
+  $ make
+  $ make install
+
+ +

It will install libOpenVG.so, libEGL.so, and one +or more EGL drivers.
