ABSTRACT:
A method and apparatus for producing a visually improved image on a video display in a computer controlled display system. The system and method converts a quadrilateral polygon to a pair of triangles by computing the dot product of the normal unit vectors of one set of opposing pair of vectices and computing the dot product of the normal unit vectors of the other set of opposing pair of vertices and then comparing these two dot products to determine which opposing pair of vertices produces the larger of the two dot products. The pair of opposing vertices which produces the largest dot product is used to form the common edge of the pair of triangles into which the quadrilateral is converted.
