Abstract: In a graphics processing system that includes one or more programmable shading stages, the shader compiler receives a shader program to be compiled (step 40), identifies any run time constant expressions in the shader program (step 41), and removes such expressions from the original shader program, and substitutes them in the original main shader program with appropriate load instructions pointing to where the output results from a pilot shader program will be stored (step 42). The shader compiler then creates a separate pilot shader program for the identified run-time constant expressions (step 43). The pilot shader program is then executed on the graphics processing pipeline (step 44), before the modified main shader program (step 45).

Abstract: A set of primitives is divided into plural sub-sets of primitives, and a tree representation for representing the set of primitives in which each leaf node of the tree represents one of the sub-sets, and each parent node of the tree represents a sub-set of primitives corresponding to the combination of the sub-sets of primitives of all of its child nodes, is generated. For each node of the tree representation data indicating: the sub-set of primitives that the node represents; the vertices that are used by the primitives in the sub-set of primitives that the node represents; and the volume of space that the sub-set of primitives that the node represents falls within, is determined. The tree representation is then used to determine a set of primitives and a set of vertices to be processed when processing the set of primitives for the output frame.
