Claim:
1. A method of assigning primitives to tiles in a graphics processing system which has a rendering space subdivided into a plurality of tiles, wherein each tile comprises one or more polygonal regions, the method comprising: in said graphics processing system: including, in a display list for a tile, indications of primitives which are present within a polygonal region of the tile, to thereby assign the primitives to the tile, receiving a set of one or more primitives, for each of the one or more polygonal regions of a tile: if it is determined that the set of one or more primitives entirely obscures previous primitives, which are included in the display list for the tile, in all of the one or more polygonal regions of the tile, setting a display list start pointer to indicate that an indication of one of the one or more primitives of the set is a starting point in the display list for the tile.
