Abstract
A process for efficiently drawing subdivision surfaces. The present invention operates within a computer system for visually displaying 3 dimensional (3D) surfaces on a display. The present invention pulls polygons from a polygon mesh of a 3D surface. The polygons are stored into a 2 dimensional array such that the vertices of the polygons occupy nodes of the 2 dimensional array and are readily accessed. The polygons are subsequently divided into a plurality of resulting polygons. The resulting polygons are then sent to a graphics pipeline, wherein the graphics pipeline renders the resulting polygons into a 3D image on the computer display.
