Abstract
Subdividing a subdivision surface includes traversing the subdivision surface to locate a target polygon on the subdivision surface, partially subdividing the target polygon, re-traversing the subdivision surface to locate the target polygon on the subdivision surface, and additionally subdividing the target polygon. Data is stored indicating a point in a subdividing process where the partially subdividing left off and the additionally subdividing includes subdividing the target polygon beginning at the point in the subdividing process where the partially subdividing left off.
