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GL_HP_occlusion_test - this is superceded by GL_ARB_occlusion_query.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Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by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