Abstract:
1. A method of processing a graphics primitive 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 set of sampling points of the image to be displayed, whether the primitive covers that 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; associating with each graphics fragment information indicating which of the sampling points in the set of sampling points that the fragment corresponds to are being rendered in common by the fragment; rendering some or all of the graphics fragments to determine a set of fragment data for each rendered fragment; and storing, for one or more of the rendered fragments, a set of the rendered fragment data for the rendered fragment for each sampling point that the information associated with the fragment indicates was rendered in common by the fragment.
