Patent ID: 8368691

Claim:
A method for rendering computer graphics images in a tile based rendering system, the method comprising the steps of: in a geometry processing phase, retrieving untransformed position data from stored untransformed static geometry data in a memory; transforming the retrieved untransformed position data to screen space; compiling for screen space position data a list of corresponding pointers to the static geometry data in the memory from which the position data was retrieved for each of a plurality of rectangular areas; and, in a rasterization phase, for each of the plurality of rectangular areas, retrieving pointer data from each respective list of corresponding pointers; retrieving the untransformed position data from the stored untransformed static geometry data in the memory, the retrieved data being data pointed to by the retrieved pointer data for each respective list; transforming the retrieved untransformed data to screen space; applying hidden surface removal and attribute processing to the thus transformed position data to obtain resulting data; and supplying the resulting data to a buffer for display.
