Michael A Cosman, Michael D Drews, Gary S Watkins: Computer graphics system with adaptive pixel multisampler. Evans & Sutherland Computer Corporation, Thorpe North & Western, October 6, 1998: US05818456 (85 worldwide citation)

An adaptive pixel multisampler generates pixel data for display using an interlocking sub-pixel sampling pattern and a frame buffer organized as a per-polygon, per-pixel heap. The interlocking sampling pattern provides the advantages of a multi-pixel shaped filter without pixel-to-pixel cross commun ...
