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GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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
|
||
|
|
---------------------- ----------------------
|
||
|
|

|
||
|
|
