1. A system for subdividing parametric patches defined by initial control points to attain control points for subpatches in accordance with established subdivision equations, comprising: means for supplying signals representative of said initial control points for a patch to be subdivided; a plurality of processors for executing said subdivision equations connected to receive said signals representative of said initial control points for a patch to be subdivided; means for controlling said processors to selectively process said signals representative of said initial control points to provide resultant signals representative of control points for subpatches; and means for receiving said resultant signals from said processors.
