| 13 | <p> |
| 14 | Mesa 6.5 is a new development release. |

| 33 | <h2>New Features</h2> |
| 34 | <ul> |
| 35 | <li>OpenGL Shading language support |
| 36 | <br> |
| 37 | This includes the GL_ARB_shader_objects, GL_ARB_shading_language_100, |
| 38 | GL_ARB_vertex_shader and GL_ARB_fragment_shader extensions. Most of |
| 39 | the work was done by Michal Krol. |
| 40 | There's probably a fair number of bugs since this is a pretty large, |
| 41 | complicated body of code. |
| 42 | <br> |
| 43 | The OpenGL 2.0 interface to these features will be implemented in a |
| 44 | future version of Mesa, |
| 45 | |
| 46 | <li>GL_EXT_timer_query |
| 47 | <br> |
| 48 | Used to measure the time of OpenGL operations at high precision. |
| 49 | Only supported in the software/Xlib driver at this time. |
| 50 | |
| 51 | <li>GL_EXT_packed_depth_stencil |
| 52 | <br> |
| 53 | Defines a new GL_DEPTH_STENCIL_EXT pixel format. |
| 54 | |
| 55 | <li>GL_EXT_framebuffer_blit |
| 56 | <br> |
| 57 | A simplified glCopyPixels-like feature for copying pixel rectangles. |
| 58 | |
| 59 | <li>GL_ARB_half_float_pixel |
| 60 | <br> |
| 61 | Adds a new half-precision floating point format for image transfers, |
| 62 | such as for glDrawPixels, glReadPixels, glTexImage, etc. |
| 63 | </ul> |
| 64 | |
| 65 | <h2>Changes</h2> |
| 66 | <ul> |
| 67 | <li>removed GL_HP_occlusion_test (use GL_ARB_occlusion_query instead) |
| 68 | <li>removed GL_SGIX/SGIS_pixel_texture extensions |
| 69 | </ul> |
| 70 | <h2>Bug fixes</h2> |
| 71 | <ul> |
| 72 | <li>fixed glxcontextmodes.c datatype problem (bug 5835) |
| 73 | <li>fixed aix-gcc build/install bugs (bug 5874) |
| 74 | <li>fixed some bugs in texture env program generation |
| 75 | <li>glXCopyContext() didn't handle texture object bindings properly |
| 76 | <li>glXCopyContext() didn't copy all lighting state |
| 77 | <li>fixed FreeBSD config (Pedro Giffuni) |
| 78 | <li>fixed some minor framebuffer object bugs |
| 79 | <li>replaced dprintf() with _glu_printf() in GLU (bug 6244) |
| 80 | <li>fixed a number of thread safety bugs/regressions |
| 81 | <li>fixed a number of GLU tesselator bugs (John Shell, bug 6339) |
| 82 | <li>paletted texturing was broken w/ floating point palettes (K. Schultz) |
| 83 | <li>lots of assorted framebuffer object bug fixes |
| 84 | </ul> |
| 85 | |
| 86 | |
| 87 | <h2>Known Issues</h2> |
| 88 | <ul> |
| 89 | <li>Rendering to depth textures will not work. Rendering to GL_DEPTH_STENCIL |
| 90 | textures should work. |
| 91 | </ul> |
| 92 | |
| 93 | |
| 94 | <h2>Driver Interface Changes</h2> |
| 95 | <ul> |
| 96 | <li>Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by |
| 97 | the two-sided versions: Driver.Stencil*Separate(). |
| 98 | <li>Render-to-texture: The functions for rendering to textures have changed. |
| 99 | </ul> |
| 100 | |
| 101 | |
| 102 | <h2>To Do (someday) items</h2> |
| 103 | <ul> |
| 104 | <li>Switch to freeglut |
| 105 | <li>Increase MAX_DRAWBUFFERS |
| 106 | <li>Fix linux-glide target/driver. |
| 107 | <li>Fix lambda calculation for frag progs. |
| 108 | </ul> |
| 109 | |
