Abstract
A graphics processing system having a rendering space divided into a plurality of tiles. The system comprises geometry processing logic and rasterization logic. The geometry processing logic is configured to generate transformed position data for each of a plurality of untransformed primitives based on untransformed geometry data associated therewith; group the plurality of untransformed primitives into a plurality of primitive blocks; and generate an untransformed display list for each tile based on the transformed position data. Each untransformed display list comprises: (i) information identifying each untransformed primitive block that comprises at least one untransformed primitive that, when transformed, falls at least partially with the tile; and (ii) for each identified untransformed primitive bock, information identifying the untransformed primitives or transformed primitives related to that untransformed primitive block relevant for rendering the tile. The rasterization logic is configured to fetch, for each primitive block identified in an untransformed display list for a tile, untransformed geometry data for all of the untransformed primitives in that untransformed primi…
