Abstract

ABSTRACT: In this paper, a method is proposed for retaining size and shape of circular feature on a deforming subdivision surface. An effective alternating local/global optimization method with projections is used to retain features. The multi-resolution property and the ability to generate smooth surface from arbitrary topology of subdivision surface allows user to model freeform objects. The multi-resolution editing of subdivision surface is especially useful for obtaining a smooth mesh by editing a low-complexity mesh. Constrained deformation is applied to the low complexity mesh. This speed up the computation involved, and allows the constrained deformation of complex mesh to be performed in a real-time manner. The method proposed illustrates that constrained deformation can be applied to multi-resolution model constructed with subdivision surface such that essential functional features can be retained in a shape editing process.
