Abstract

Methods and graphics processing systems are provided which render primitives using a rendering space which is subdivided into a plurality of regions. Geometry processing logic is configured to perform a geometry processing phase which comprises: determining, for each of a plurality of primitives which are present in a region, whether the primitive totally covers the region; and storing data for the primitives which are present in the region, wherein the stored data comprises, for each of the primitives which are determined to totally cover the region, data to indicate total coverage of the region. Rendering logic is configured to perform a rendering phase for rendering primitives within the region. The rendering phase comprises: retrieving the stored data for the primitives which are present in the region; selectively processing the primitives which are present in the region based on the retrieved data to determine which sample points within the region are covered by the primitives, wherein if the retrieved data includes data which indicates total coverage of the region for a particular primitive then said processing to determine which sample points within the region are covered by the particular primitive is skipped; and determining rendered values at the sample points within the region based on the primitives which cover the respective sample points.
