REQUEST ------------------------------------------------------------------------
<GMT13-Dec-2003 19:14:15GMT> Kurt Zimmerman:
* SUMMARY
The OpenGL libraries provided with Apples version of X11 do not provide access to many of the graphics card features available on the ATI 9600 mobility card.
* STEPS TO REPRODUCE
1. Open an Xterm window on a PowerBook G4 15" or 17" with 9600 mobility card.
2. type "glxinfo"
3. As a specific example note that GL_ARB_fragment_program is listed as an available extension (I'm sure there are other examples but this is one I need).
4. type "cd /usr/X11R6/include/GL"
5. type "grep GL_ARB_fragment_program *.h" Note that It doesn't exist.
6. type "cd /usr/X11R6/lib"
7. type "nm libGL.dylib | grep -i glBindProgramARB" Again the needed function is not defined in the library.
* RESULTS
I expected the X11/OpenGL installation to match the graphics card. Or at least be able to download a graphics card specific patch.
* REGRESSION
This is a static problem.
* NOTES
I'm just requesting that developers be able to download a patch for the OpenGL libraries that allows us to access features of the graphics card. I'm currently trying to see if I can work around this problem by using glew (glew.sourceforge.net)
