Abstract:
A tiling unit assigning primitives to tiles in a graphics processing system which has a rendering space subdivided into a plurality of tiles. Each tile can comprise one or more polygonal region. Mesh logic of the tiling unit can determine that a plurality of primitives form a mesh and can determine whether the mesh entirely covers a region. If the mesh entirely covers the region then a depth threshold for the region can be updated so that subsequent primitives which lie behind the depth threshold are culled (i.e. not included in the display list for a tile). This helps to reduce the number of primitive IDs included in a display list for a tile which reduces the amount of memory used by the display list and reduces the number of primitives which a hidden surface removal (HSR) module needs to fetch to perform HSR on the tile.

Claim (Index 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 regions, the method comprising:\n receiving a mesh comprising a plurality of primitives; identifying external edges of the mesh; using the identified external edges of the mesh to determine whether the mesh entirely covers a region of a tile; if it is determined that the mesh entirely covers the region of the tile, selectively updating a depth threshold for the region in dependence on a depth value for at least one of the primitives of the mesh which is present within the region of the tile; and selectively assigning, to the tile, one or more of the primitives of the mesh which are present within the region of the tile, in dependence on the depth threshold for the region.
