Abstract
The present invention is related to rendering computer animated video and/or images generally, and to adjusting the origins of rays cast for object-edge positions. The present invention includes identifying a location of a vertex positioned on a perimeter of an object defined in the object scene by a plurality of vertices. The plurality of vertices include the vertex positioned on the perimeter of the object. A shading position that corresponds to, but is offset from, the vertex is then established. A shading value is then computed for the vertex by reference to the shading position. The shading value may be computed, for example, by casting a ray from the shading position.
