A novel FEM-based dynamic framework for subdivision surfaces
Subdivision surfaces have been extensively used to model smooth shapes of arbitrary topology. Recursive subdivision on an userdefined initial control mesh generates a visually pleasing smooth surface in the limit. However, users have to carefully specify the initial mesh and/or painstakingly manipulate the control vertices at different levels of subdivision hierarchy to satisfy various functional and aesthetic requirements in the limit surface. This modeling drawback results from the lack of direct manipulation tools for the limit surface. In this paper, we integrate physicsbased modeling techniques with geometric subdivision methodology and present an unified approach for arbitrary subdivision schemes. Our dynamic framework permits users to directly manipulate the limit subdivision surface via physics-based ”force” tools. The key contribution of this unified approach is to formulate the smooth limit surface of any subdivision scheme as a single type of novel finite elements. ...
