New Features
|
||||
------------
|
||||
|
||||
GL_EXT_timer_query - used to get elapsed time information from the renderer.
|
||||
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.
|
||||
|
||||
GL_EXT_packed_depth_stencil - defines a new GL_DEPTH_STENCIL_EXT pixel format.
|
||||
The OpenGL 2.0 interface to these features will be implemented in a
|
||||
future version of Mesa,
|
||||
|
||||
GL_EXT_framebuffer_blit - simplified glCopyPixels-like feature
|
||||
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.
|
||||
|
||||
Known Issues
|
||||
------------
|
||||
|
||||
Rendering to depth or depth/stencil textures will not work, results in
|
||||
failed assertions, etc.
|
||||

||||
|
||||

||||
Driver Interface Changes
|
||||
------------------------
|
||||
|
||||
Stencil: The Driver.StencilOp/Func/Mask() functions have been replaced by
|
||||
the two-sided versions: Driver.Stencil*Separate().
|
||||
|
||||
|
||||
|
||||
To Do
|
||||
-----
|
||||
Fix linux-glide target/driver.
|
||||
Fix lambda calculation for frag progs.
|
||||
|
||||
GL_ARB_half_float_pixel
|
||||
Adds a new half-precision floating point format for image transfers,
|
||||
such as for glDrawPixels, glReadPixels, glTexImage, etc.
