New Features
|
||||
------------
|
||||
|
||||
- Intel i965 "broadwater" DRI driver
|
||||
- GL_APPLE_vertex_array_object - allows encapsulation of a set of
|
||||
vertex arrays in an object.
|
||||
- GL_EXT_texture_sRGB - non-linearly mapped texture formats
|
||||
- GL_EXT_gpu_program_parameters - addes a few new functions for setting
|
||||
multiple vertex/fragment program parameters with one call.
|
||||
- "engine" demo
|
||||
- updated fbdev driver and GLUT for fbdev (Sean D'Epagnier)
|
||||
- many updates to the DRI drivers
|
||||
|
||||
Changes
|
||||
-------
|
||||
|
||||
- The glVertexAttribARB functions no longer alias the conventional
|
||||
vertex attributes.
|
||||
- glxinfo program prints more info with -l option
|
||||
- GL_FRAGMENT_PROGRAM_NV and GL_FRAGMENT_PROGRAM_ARB are now
|
||||
compatible, in terms of glBindProgramARB()
|
||||
- The GL_ARB_vertex_program attribute ``vertex.weight`` is now accepted
|
||||
by the parser, even though the GL_ARB_vertex_blend and
|
||||
GL_EXT_vertex_weighting extensions aren't supported. Allows Warcraft
|
||||
to run.
|
||||
|
||||
Bug fixes
|
||||
---------
|
||||
|
||||
- fixed broken texture border handling for depth textures (bug 6498)
|
||||
- removed the test for duplicated framebuffer attachments, per version
|
||||
117 of the GL_EXT_framebuffer_object specification
|
||||
- fixed a few render-to-texture bugs, including render to depth texture
|
||||
- clipping of lines against user-defined clip planes was broken (6512)
|
||||
- assembly language dispatch for SPARC was broken (bug 6484)
|
||||
- assorted compilation fixes on various Unix platforms (Dan Schikore)
|
||||
- glPopAttrib could restore an invalid value for GL_DRAW_BUFFER
|
||||
- assorted minor fixes for 16 and 32 bit/channel modes
|
||||
- fixed assorted bugs in texture compression paths
|
||||
- fixed indirect rendering vertex array crashes (bug 6863)
|
||||
- glDrawPixels GL_INDEX_OFFSET didn't always work
|
||||
- fixed convolution memory leak (bug 7077)
|
||||
- rectangular depth textures didn't work
|
||||
- invalid mode to glBegin didn't generate an error (bug 7142)
|
||||
- 'normalized' parameter to glVertexAttribPointerARB didn't work
|
||||
- disable bogus GLX_SGI_video_sync extension in xlib driver
|
||||
- fixed R128 driver locking bug (Martijn van Oosterhout)
|
||||
- using evaluators with vertex programs caused crashes (bug 7564)
|
||||
- fragment.position wasn't set correctly for point/line primitives
|
||||
- fixed parser bug for scalar sources for GL_NV_fragment_program
|
||||
- max fragment program length was incorrectly 128, now 1024
|
||||
- writes to result.depth in fragment programs weren't clamped to [0,1]
|
||||
- fixed potential dangling pointer bug in glBindProgram()
|
||||
- fixed some memory leaks (and potential crashes) in Xlib driver
|
||||
- fixed a number of build issues on HP-UX (Christopher Bell)
|
||||
- accum buffer didn't work with OSMesa interface
|
||||
|
||||
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.

||||
