<p>A method and apparatus, for use in a computer image generation system (10) wherein polygons are displayed on a video display (18), for encoding data representing intersections of the polygons and the pixels. The method comprises the steps of receiving input data signals characterizing a set of coordinates of each of at least three vertices of each polygon to be displayed through an input control interface (22), each different pair of the vertices of each polygon defining a different edge of the polygon; and generating, through a geometry processor (14), responsive to the received vertex data signals, edge data signals describing the intersection, if any, of the polygon edges with each pixel to be displayed.</p> |
