Subdivision surface modeling system based on arbitrary topological curves network and combined subdivision

Abstract

Arbitrary topological curve network has no restriction in topology structure, so it has more powerful representing ability in defining complex surfaces. A complex surface modeling system is presented based on arbitrary topological curve network and the improved combined subdivision method, its functions including creating and editing curve network, and generating and modifying curve network’s interpolated surface. This modeling system can be used to the process of products’ concept design, and its applications is also significant to the development of subdivision method.
