US Patent 7742061 Method and related apparatus for image processing

Method and related apparatus for image processing. When projecting a polygonal object in three-dimensional space onto a two-dimensional screen according to a viewing range, faces of the object which intersect boundaries of the viewing range are clipped to form clipped planes. Vertices of all of the clipped planes of the object are recorded in one vertex list according to a triangle-list primitive, so as to increase efficiency of the image processing.
