| Mesa 6.5 Release Notes |
| |
| |
| |
| Introduction |
| ------------ |
| |
| Mesa uses an even/odd version number scheme like the Linux kernel. |
| Odd numbered versions (such as 6.5) designate new developmental releases. |
| Even numbered versions (such as 6.4) designate stable releases. |
| |
| |
| |
| 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. |
| |
| |
| |
| Removed Extensions |
| ------------------ |
| |
| The following extensions have been removed: |
| |
| GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query. |
| |
| |
| |
| 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| Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by |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. |
| |
| |
| |
| Driver Status |
| ---------------------- ---------------------- |
| DRI drivers varies with the driver |
| XMesa/GLX (on Xlib) implements OpenGL 1.5 |
| OSMesa (off-screen) implements OpenGL 1.5 |
| Glide (3dfx Voodoo1/2) implements OpenGL 1.3 |
| SVGA implements OpenGL 1.3 |
| Wind River UGL implements OpenGL 1.3 |
| Windows/Win32 implements OpenGL 1.5 |
| DJGPP implements OpenGL 1.5 |
| GGI implements OpenGL 1.3 |
| BeOS implements OpenGL 1.5 |
| Allegro needs updating |
| D3D needs updating |
