ABSTRACT:
A system and method for simulating motion blur. Intersections of pixel sampling points with leading and trailing edges of moving polygons are identified. The intersection points define segments of coverage of the pixel sampling point by a polygon. A segment list is sorted to identify segments that are associated with visible polygons. The segments of visible polygons are passed to shading and texturing functions which individually determine the temporal sampling points for a single polygon or a group of polygons.
