Abstract
In a tile-based graphics processor, primitive lists (bins) are prepared for 2×2 blocks of tiles. The processor also determines and stores for each primitive in a bin, distribution information indicating the distribution of the primitive within the set of tiles that the bin corresponds to. Thus a primitivethat is found by its bounding boxto reside in two of the four tiles that make up the set of 2×2 tilesis also associated with a tile coverage bitmap of the form '0101' to indicate that it lies in tiles 'and “of the 2×2 group of tiles. The graphics processor uses the coverage bitmap (information) to determine whether a primitive should be processed for the tile currently being processed.
