Curved surface subdivision apparatus

摘要

A subdivision level determination unit ( 13 ) in a curved surface subdivision apparatus ( 10 ) accepts an input of information about control points that define a shape of a curved surface and determines the subdivision level for the surface. Next, it sets, for a subdivision processing operation control unit ( 16 ), a control table corresponding to the determined subdivision level. The subdivision processing operation control unit ( 16 ) executes the subdivision processing while controlling a work memory unit ( 14 ) and a subdivision processing operation unit ( 15 ) based on the set control table.
