I misspoke here. gl_NumSamples is a uniform, and is the number of samples in the framebuffer. It isn't the implementation's maximum number of color samples, which is what actually goes in that formula. AFAICT, GLSL does not expose the maximum number of supported color samples as a compile time constant, so there is no way to actually write code to explicitly size this array correctly on all (theoretical) implementations. Unless you GetIntegerv and generate shader strings dynamically... I'm pretty sure people are just going to access element 1 and call it good. --Ken _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
