Abstract
A system and method of rendering polygons in graphics system using incremental iterative addition in place of complex division operations. A setup engine provides relevant values to edge and span walk modules for rapid processing and rendering of polygon characteristics including material values. Characteristic functions are iterated with respect to polygon area and along individual spans to derive values for each pixel therein.
