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.
