Abstract
A technique for universally rasterizing graphic primitives used in computer graphics is described. Configurations of the technique include determining three edges and a bounded region in a retrofitting bounding box. Each primitive has real and intrinsic edges. The process uses no more than three real edges of any one graphic primitive. In the case of a line, a third edge is set coincident with one of its two real edges. The area between the two real edges is enclosed by opposing perimeter edges of the bounding box. In the case of a rectangle, only three real edges are used. The fourth edge corresponds to a bounding edge provided by the retrofitting bounding box. In exemplary applications, the technique may be used in mobile video-enabled devices, such as cellular phones, video game consoles, PDAs, laptop computers, video-enabled MP3 players, and the like.
