I ran the test on a Solaris 8 system with the OpenGL "ogl123_rt32_64" downloaded from Sun's OpenGL for Solaris website (Ultra 10 with Elite3D graphics) and it rendered correctly. -andy ------------------------------------------------------- This sf.net email is sponsored by:ThinkGeek Gadgets, caffeine, t-shirts, fun stuff. http://thinkgeek.com/sf _______________________________________________ Dri-devel mailing list [EMAIL PROTECTED] https://lists.sourceforge.net/lists/listinfo/dri-devel
