Abstract
Various methods, apparatuses, and systems are described in which subdivided polygons are derived from a first polygon. Bin assignments of subdivided polygons derived from a first polygon may be stored. One or more reference coordinate points associated with coordinates of the first polygon may be stored. One or more reference coordinate points associated with the coordinates of the first polygon on a subsequent frame may be compared to the stored one or more reference coordinate points from a previous frame. The bin assignments for the corresponding subdivided polygons for the subsequent frame may be reused if the results of the comparison are within a preset threshold quantity.
