Abstract
An apparatus and method of selectively over-sampling image data, anti-aliasing of polygons that produces quality images comparing favorably to full over-sampling techniques while requiring less computation than full over-sampling techniques. Using a hierarchical tiler to perform edge calculations for any given polygon, and then selectively over-sampling pixels along the edge, image quality may be greatly improved through anti-aliasing the polygon edges, with a small increase in computation time or hardware.
