| 21 | New Features |
| 22 | ------------ |
| 23 | |
| 24 | - OpenGL Shading language support |
| 25 | |
| 26 | This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100, |
| 27 | GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of |
| 28 | the work was done by Michal Krol. There's probably a fair number of |
| 29 | bugs since this is a pretty large, complicated body of code. |
| 30 | |
| 31 | The OpenGL 2.0 interface to these features will be implemented in a |
| 32 | future version of Mesa, |
| 33 | |
| 34 | - GL_EXT_timer_query |
| 35 | |
| 36 | Used to measure the time of OpenGL operations at high precision. Only |
| 37 | supported in the software/Xlib driver at this time. |
| 38 | |
| 39 | - GL_EXT_packed_depth_stencil |
| 40 | |
| 41 | Defines a new GL_DEPTH_STENCIL_EXT pixel format. |
| 42 | |
| 43 | - GL_EXT_framebuffer_blit |
| 44 | |
| 45 | A simplified glCopyPixels-like feature for copying pixel rectangles. |
| 46 | |
| 47 | - GL_ARB_half_float_pixel |
| 48 | |
| 49 | Adds a new half-precision floating point format for image transfers, |
| 50 | such as for glDrawPixels, glReadPixels, glTexImage, etc. |
| 51 | |
| 52 | Changes |
| 53 | ------- |
| 54 | |
| 55 | - removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) |
| 56 | - removed GL_SGIX/SGIS_pixel_texture extensions |
| 57 | |
| 58 | Bug fixes |
| 59 | --------- |
| 60 | |
| 61 | - fixed glxcontextmodes.c datatype problem (bug 5835) |
| 62 | - fixed aix-gcc build/install bugs (bug 5874) |
| 63 | - fixed some bugs in texture env program generation |
| 64 | - glXCopyContext() didn't handle texture object bindings properly |
| 65 | - glXCopyContext() didn't copy all lighting state |
| 66 | - fixed FreeBSD config (Pedro Giffuni) |
| 67 | - fixed some minor framebuffer object bugs |
| 68 | - replaced dprintf() with \_glu_printf() in GLU (bug 6244) |
| 69 | - fixed a number of thread safety bugs/regressions |
| 70 | - fixed a number of GLU tesselator bugs (John Shell, bug 6339) |
| 71 | - paletted texturing was broken w/ floating point palettes (K. Schultz) |
| 72 | - lots of assorted framebuffer object bug fixes |
| 73 | |
| 74 | Known Issues |
| 75 | ------------ |
| 76 | |
| 77 | - Rendering to depth textures will not work. Rendering to |
| 78 | GL_DEPTH_STENCIL textures should work. |
| 79 | |
| 80 | Driver Interface Changes |
| 81 | ------------------------ |
| 82 | |
| 83 | - Stencil: The Driver.StencilOp/Func/Mask() functions have been |
| 84 | replaced by the two-sided versions: Driver.Stencil*Separate(). |
| 85 | - Render-to-texture: The functions for rendering to textures have |
| 86 | changed. |
| 87 | |
| 88 | To Do (someday) items |
| 89 | --------------------- |
| 90 | |
| 91 | - Switch to freeglut |
| 92 | - Increase MAX_DRAWBUFFERS |
| 93 | - Fix linux-glide target/driver. |
| 94 | - Fix lambda calculation for frag progs. |
