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.

New Features in Mesa 5.1
|
|
|
|
------------------------

|
|
|
2003-06-10 16:01:45 +01:00
|
|
|
New directory tree
|
|
|
|
The whole Mesa directory tree has been cleaned up and reorganized.
|
|
|
|
Some old stuff has been abandoned. Lots of non-Unix makefiles will
|
|
|
|
have to be updated.
|
|
|
|
|
|
|
|
For now, autoconf/automake support has been removed. New autoconf/automake
|
|
|
|
files will added if they meet certain criteria.

|
GL_ATI_texture_env_combine3 extension
|
|
|
|
This adds a few new texture combine modes.

|
|
|
GL_SGI_texture_color_table
|
2003-02-13 16:01:33 +00:00
|
|
|
Adds a color table lookup to the RGBA texture path. There's a separate
|
|
|
|
color table for each texture unit.

|
|
|
GL_NV_fragment_program
|
|
|
|
NVIDIA's fragment-level programming feature.
|
2003-06-01 17:27:37 +01:00
|
|
|
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.
|
|
|
|
|
2003-06-10 16:01:45 +01:00
|
|
|
GL_EXT_texture_rectangle
|
|
|
|
Identical to GL_NV_texture_rectangle
|
|
|
|
|
2003-06-13 03:37:27 +01:00
|
|
|
GL_ARB_occlusion_query
|
|
|
|
Useful for visibility-based culling.

Build System Changes
|
|
|
|
--------------------
|
|
|
|
|
|
|
|
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 files related to vertex and fragment programming have changed.
|
|
|
|
Old files:
|
|
|
|
vpexec.[ch]
|
|
|
|
vpparse.[ch]
|
|
|
|
vpstate.[ch]
|
|
|
|
New files:
|
|
|
|
nvvertprog.h - NV vertex program definitions

|
|
|
|

|
|
|
|

|
|
|
|
nvprogram.[ch] - NV program API functions

|
|
|
|
|
2003-03-29 16:39:52 +00:00
|
|
|
Removed files:
|
|
|
|
swrast/s_historgram.[ch] - moved into src/histogram.c
|
2003-03-01 01:50:13 +00:00
|
|
|
|
2003-06-01 17:27:37 +01:00
|
|
|
Other New files:
|
2003-03-30 17:17:54 +01:00
|
|
|
bufferobj.[ch] - GL_ARB_vertex_buffer_object functions
|
2003-06-01 17:27:37 +01:00
|
|
|
arbprogram.[ch] - GL_ARB_vertex/fragment_program functions
|
|
|

version.h - defines the Mesa version info
|
|
|
|
|
|
|
|
|
|
|
|
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.
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
|
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 call the _mesa_enable_1_4_extensions() function.
