Such as?

Both EXT_texture_sRGB and ARB_framebuffer_sRGB are supported under GL 3.2 (through the core API path)
as well as GL 2.x (via extensions on supported renderers) on this platform.

As per the OpenGL specification GL_ALPHA maps to the following { RGBA } vector:



{ R = 0, G = 0, B = 0, A = A }


The following fragment shader demonstrates how to sample from GL_ALPHA:

A number of vendors (i.e. Apple, ...) have had support for rendering YCbCr 4:2:2 formats through the OpenGL API. For example on Mac OS X (going all the way back to 10.2.x) you have support for...

Post the shader(s) and what renderer(s) you were testing with. Furthermore as OSC stated above please file a Radar (i.e. http://developer.apple.com/bugreporter/) ASAP.

Considering that the GLUT API (via /System/Library/Frameworks/GLUT.framework) is shipping by default on Mac OS X I don't see why this would be needed.

Just make sure you #include the proper...

Well if you are interested in learning about the OpenGL pipeline from a programmable standpoint (i.e. ARB_[vertex, fragment]_shader or ARB_[vertex, fragment]_program) then it would be a good idea to...

Heh, that make sense (stupid me). I have come up with this:

!!ATIfs1.0

StartConstants;

CONSTANT c0 = {0.299, 0.587, 0.114};
CONSTANT c1 = {0.596, 0.275, 0.321};
CONSTANT c2 = {0.212,...

OK, I have an application that decodes YUV video
that is textured in GL (on a mac), I would like to
use ATI_text_fragment_shader for video processing
but I need to do a YUV -> RGB color...
