Abstract: A graphics processing pipeline includes a vertex transformation stage 14 having a vertex transformation cache 20. If a request to transform vertex data is received and the vertex transformation cache 20 indicates that the transformed vertex data for that received request has already been generated, then a pointer to that previously generated transformed vertex data is output within a result data stream in place of the transform vertex data. The transform vertex data is stored to a memory 10 before being retrieved as required by a rasterization stage 16.

Abstract: A graphics processing apparatus performs an intermediate processing pass in which region lists that indicate geometry for respective regions of an intermediate projection surface are generated and stored. A subsequent processing pass is then performed in which a region of the intermediate projection surface is selected using a vector for a fragment, and geometry data for shading the fragment is obtained with reference to the region list that was stored for the selected region in the intermediate processing pass. The fragment can then be shaded using the obtained data for the geometry. The apparatus can provide a render output that is not limited by the resolution of an intermediate render output.
