UNIFIED SUBDIVISION FOR ARBITRARY AND PARTIAL DEGREE SURFACES AND CURVES WITH CONSISTENT PROPERTY PROPAGATION

摘要

To create an arbitrary-degree limit surface from a mesh, the mesh is firstlinearlysubdivided. Additional linear subdivision and smoothing operations areperformed on theinitially linearly subdivided mesh. The number of sets of linear subdivisionandsmoothing operations depends on the desired surface-degree and subdivisionlevel. Thisprocedure can be used to create arbitrary-degree limit surfaces withoutperforming a dualoperation. During subdivision the topology of the intermediate mesh isindependent ofthe goal limit surface-degree.
