Abstract
Embodiments of the present invention provide a method and apparatus for determining the zones that a polygon overlaps to minimize the bins that are updated during binning and reduce the number of polygons to be set up in the render phase. The polygons supported include, but are not limited to, points, lines, triangles and rectangles. Each zone has associated with it a batch buffer to which data is written back for the polygons that overlap that zone. This data includes the setting up of state and the indices for those polygons. Since the zones that a polygon overlaps is precisely determined, the data written back is minimized and the polygons to be set up during the render phase is optimally reduced.
