| 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 |
