| 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. |
