Patent ID: 7920139

Claim:
A method of processing graphics primitives of an image to be displayed, said method is carried out on a graphics processor, the method comprising: determining for each sampling point of a plurality of sets of sampling points of the image to be displayed whether a graphics primitive covers the sampling point; generating a set of graphics fragments for rendering the primitive, each graphics fragment corresponding to a set of sampling points found to include a sampling point that is covered by the primitive; rendering some or all of the graphics fragments generated for the primitive to determine a set of fragment data for each rendered graphics fragment; and storing in an array of fragment data a separate set of rendered fragment data for each sampling point of the sets of sampling points that correspond to the rendered graphics fragments found to be covered by the primitive, wherein said step of generating comprises selectively generating at least one graphics fragment for rendering for a set of sampling points found to include a sampling point covered by said primitive.
