Abstract
Surface editing is performed in typical computer-aided design (CAD) software products by using special tools to edit special surfaces, such as b-splines or subdivision surfaces. It is recognized herein that current approaches to editing surfaces are not generally applicable. For example, common CAD and surface modeling software products are tailored to a specific surface type or vendor specific format, or otherwise are not generally applicable to given analytical and non-analytical surfaces. In various embodiments described herein, subdivision surfaces can be generated to represent any surface. Further, surfaces can be manipulated using a control cage associated with the subdivision surface.
