This adds another tiny piece of ARB_gpu_shader5. >From the ARB_gpu_shader5 specification:
The variable gl_SampleMaskIn is an array of integers, each holding a bitfield indicating the set of samples covered by the primitive generating the fragment during multisample rasterization. The array has ceil(<s>/32) elements, where <s> is the maximum number of color samples supported by the implementation. Bit <n> or word <w> in the bitfield is set if and only if the sample numbered <w>*32+<n> is considered covered for this fragment shader invocation. At this stage we statically set the size of the array to be 1, same as we do for ARB_sample_shading's gl_SampleMask[] output, since none of our supported hardware can do >32x MSAA. -- Chris _______________________________________________ mesa-dev mailing list mesa-dev@lists.freedesktop.org http://lists.freedesktop.org/mailman/listinfo/mesa-dev
