- Mesa 5.1 release notes
-
- December 17, 2003
-
- 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 5.1) designate new developmental releases.
-
-
-Bug fixes
----------
-See the VERSIONS file for a list of bugs fixed in this release.
-
-
-
-New Features in Mesa 5.1
-------------------------
-
-GL_ARB_vertex_program / GL_ARB_fragment_program
- Michal Krol and Karl Rasche implemented these extensions. Thanks!
- Be aware that there may be some rough edges and lurking bugs.
-
-GL_ATI_texture_env_combine3 extension
- This adds a few new texture combine modes.
- Contributed by Ian Romanick.
-
-GL_SGI_texture_color_table
- Adds a color table lookup to the RGBA texture path. There's a separate
- color table for each texture unit.
- Contributed by Eric Plante.
-
-GL_NV_fragment_program
- NVIDIA's fragment-level programming feature.
- Possible lurking bugs:
- - the DDX and DDY commands aren't fully tested
- - there may be bugs in the parser
- - the TEX and TXP instructions both do perspective correction
- - the pack/unpack instructions may not be correct
-
-GL_EXT_depth_bounds_test
- This extension adds a scissor-like test for the Z axis. It's used to
- optimize stencil-volume shadow algorithms.
-
-GL_NV_light_max_exponent
- Lifts the 128 limit for max light exponent.
-
-GL_EXT_texture_rectangle
- Identical to GL_NV_texture_rectangle
-
-GL_ARB_occlusion_query
- Useful for visibility-based culling.
-
-GL_ARB_texture_non_power_of_two
- Removes the restriction that texture dimensions must be powers of two.
-
-GL_ARB_vertex_buffer_object
- Allows server-side vertex arrays, optimized host/card data transfers, etc.
-
-GL_ARB_point_sprite
- ARB-approved version of GL_NV_point_sprite. Basically allows textures
- to be applied to points.
-
-GL_IBM_multimode_draw_arrays
- Allows multiple vertex arrays to be drawn with one call, including arrays
- of different types of primitives.
-
-GL_SUN_multi_draw_arrays
- An alias for GL_EXT_multi_draw_arrays, standard in OpenGL 1.4.
-
-Faster glDrawPixels / glCopyPixels in X11 driver
- If your X screen is 32bpp, glDrawPixels to the front color buffer will
- be accelerated (via XPutImage()) if the image format is GL_BGRA and the
- type is GL_UNSIGNED_BYTE. No raster operations, such as depth test,
- blend, fog, etc. can be enabled.
-
- If your X screen is 16bpp, glDrawPixels to the front color buffer will
- be accelerated (via XPutImage()) if the image format is GL_RGB and the
- type is GL_UNSIGNED_SHORT_5_6_5. No raster operations, such as depth
- test, blend, fog, etc. can be enabled.
-
- glCopyPixels() calls for the front color buffer will be accelerated
- (via XCopyArea()) if no raster operations, such as depth test, blend,
- fog, pixel zoom, etc. are enabled.
-
- The speed-up over typical software rendering is a factor of 10 for
- glDrawPixels and 100 for glCopyPixels.
-
-
-With the addition of GL_ARB_occlusion_query, GL_ARB_vertex_buffer_object,
-GL_ARB_texture_non_power_of_two and GL_EXT_shadow_funcs, Mesa 5.1 supports
-all the new features of OpenGL 1.5. Mesa 6.0 (the next stable release)
-will advertise GL_VERSION = "1.5".
-
-
-
-Vertex/Fragment program debugger
---------------------------------
-
-GL_MESA_program_debug is an experimental extension to support
-interactive debugging of vertex and fragment programs. See the
-docs/MESA_program_debug.spec file for details.
-
-The bulk of the vertex/fragment program debugger is implemented
-outside of Mesa. The GL_MESA_program_debug extension just has minimal
-hooks for stopping running programs and inspecting programs.
-
-The progs/tests/debugger.c (only in CVS) program is an example of how
-the extension can be used. Presently, the debugger code and demo code
-is in the same file. Eventually the debugger code should be moved
-into a reusable module.
-
-As it is now, the demo lets you set breakpoings in vertex/fragment
-programs, single step, and print intermediate register values. It's
-basically just a proof of concept.
-
-
-
-Directory tree reorganization
------------------------------
-
-The directory structure for Mesa has been overhauled to improve its layout.
-All source code for Mesa, GLU, GLUT, etc is now under the src/ directory
-in appropriate subdirectories.
-
-The Mesa source code and drivers has been reorganized under src/mesa/.
-
-All demonstration programs and tests are now in subdirectories under progs/.
-
-
-
-Build System Changes
---------------------
-
-The GNU automake/autoconf support has been removed. As it was, it seldom
-worked on anything but Linux. 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
-
-

-Other Changes
--------------
-
-The ctx->Driver.CreateTexture function has been removed - it wasn't used.
-
-New device driver hook functions:
- NewTextureObject - used to allocate struct gl_texture_objects
- NewTextureImage - used to allocate struct gl_texture_images
-
-New ctx->Texture._EnabledCoordUnits field:
- With the addition of GL_NV_fragment_program we may need to interpolate
- various sets of texture coordinates even when the corresponding texture
- unit is not enabled. That is, glEnable(GL_TEXTURE_xD) may never get
- called but we still may have to interpolate texture coordinates across
- triangles so that the fragment program will get them.
- This new field indicates which sets of texture coordinates are needed.
- If a bit is set in the ctx->Texture._EnabledUnits bitmask is set, the
- same bit MUST be set in ctx->Texture._EnabledCoordUnits.
-
-The ctx->_TriangleCaps field is deprecated.
- Instead of testing the DD_* bits in _TriangleCaps, you should instead
- directly test the relevant state variables, or use one of the helper
- functions like NEED_SECONDARY_COLOR() at the bottom of context.h
- While testing _TriangleCaps bits was fast, it was kludgey, and setting
- the bits in the first place could be error prone.
-
-New vertex processing code.
- The code behind glBegin, glEnd, glVertex, glNormal, etc. has been
- totally rewritten. It's a cleaner implementation now and should use
- less memory. (Keith)
-
-
-
-To Do
------
-Add screen-awareness to fakeglx.c
-
-
-
-
-Device Driver Status
---------------------
-
-A number of Mesa's software drivers haven't been actively maintained for
-some time. We rely on volunteers to maintain many of these drivers.
-Here's the current status of all included drivers:
-
-
-Driver Status
----------------------- ---------------------
-XMesa (Xlib) implements OpenGL 1.4
-OSMesa (off-screen) implements OpenGL 1.4
-FX (3dfx Voodoo1/2) implements OpenGL 1.3
-SVGA implements OpenGL 1.3
-Wind River UGL implements OpenGL 1.3
-Windows/Win32 implements OpenGL 1.4
-DJGPP implements OpenGL 1.4
-GGI implements OpenGL 1.3
-BeOS implements OpenGL 1.4
-Allegro needs updating
-D3D needs updating
-
-Note: supporting OpenGL 1.4 (vs. 1.3 or 1.2) usually only requires that the
-driver call the _mesa_enable_1_4_extensions() function.
