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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by +the two-sided versions: Driver.Stencil*Separate().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. +
