Patent ID: 7167171

Claim:
An apparatus, comprising: a graphics rendering engine configured to implement a tile based rendering algorithm that divides an initial polygon into two or more subsequent polygons smaller in individual area than the initial polygon and that shares polygon bin assignments across multiple rendering frames; and a memory to store a record associated with the initial polygon that contains one or more reference coordinate points and a list of bins that the two or more subsequent polygons should be submitted to, wherein the memory is to store bin assignments of subdivided polygons derived from a first polygon, and one or more reference coordinate points associated with coordinates of the first polygon; and wherein the engine is configured to compare one or more reference coordinate points associated with the coordinates of the first polygon on a subsequent frame to the stored one or more reference coordinate points from a previous frame, and to reuse the bin assignments for the corresponding subdivided polygons for the subsequent frame if the results of the comparison are within a preset threshold quantity.
