| <h2>New Features</h2> |
| <ul> |
| <li>OpenGL Shading language support |
| <br> |
| 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. |
| <br> |
| The OpenGL 2.0 interface to these features will be implemented in a |
| future version of Mesa, |
| |
| <li>GL_EXT_timer_query |
| <br> |
| Used to measure the time of OpenGL operations at high precision. |
| Only supported in the software/Xlib driver at this time. |
| |
| <li>GL_EXT_packed_depth_stencil |
| <br> |
| Defines a new GL_DEPTH_STENCIL_EXT pixel format. |
| |
| <li>GL_EXT_framebuffer_blit |
| <br> |
| A simplified glCopyPixels-like feature for copying pixel rectangles. |
| |
| <li>GL_ARB_half_float_pixel |
| <br> |
| Adds a new half-precision floating point format for image transfers, |
| such as for glDrawPixels, glReadPixels, glTexImage, etc. |
| </ul> |
| |
| <h2>Changes</h2> |
| <ul> |
| <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) |
| <li>removed GL_SGIX/SGIS_pixel_texture extensions |
| </ul> |
| <h2>Bug fixes</h2> |
| <ul> |
| <li>fixed glxcontextmodes.c datatype problem (bug 5835) |
| <li>fixed aix-gcc build/install bugs (bug 5874) |
| <li>fixed some bugs in texture env program generation |
| <li>glXCopyContext() didn't handle texture object bindings properly |
| <li>glXCopyContext() didn't copy all lighting state |
| <li>fixed FreeBSD config (Pedro Giffuni) |
| <li>fixed some minor framebuffer object bugs |
| <li>replaced dprintf() with _glu_printf() in GLU (bug 6244) |
| <li>fixed a number of thread safety bugs/regressions |
| <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339) |
| <li>paletted texturing was broken w/ floating point palettes (K. Schultz) |
| <li>lots of assorted framebuffer object bug fixes |
| </ul> |
| |
| |
| <h2>Known Issues</h2> |
| <ul> |
| <li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL |
| textures should work. |
| </ul> |
| |
| |
| <h2>Driver Interface Changes</h2> |
| <ul> |
| <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by |
| the two-sided versions: Driver.Stencil*Separate(). |
| <li>Render-to-texture: The functions for rendering to textures have changed. |
| </ul> |
| |
| |
| <h2>To Do (someday) items</h2> |
| <ul> |
| <li>Switch to freeglut |
| <li>Increase MAX_DRAWBUFFERS |
| <li>Fix linux-glide target/driver. |
| <li>Fix lambda calculation for frag progs. |
| </ul> |
| |
| |
