If a fragment program uses a semantic/index pair which is not mentioned by the vertex program, or is mentioned but the corresponding register is never written to, what happens?
Is the value undefined or intialized to (0, 0, 0, 1)? OpenGL seems to specify that such values are undefined, and of course that would be more convenient for Gallium drivers. What are the requirements for Gallium drivers? ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
