Physics-Based Loop Surface Modeling

Strongly inspired by the research on physics-based dynamic models forsurfaces, we propose a new method for precisely evaluating the dynamicparameters (mass, damping and stiffness matrices, and dynamic forces)for Loop surfaces without recursive subdivision regardless of regular orirregular faces. It is shown that the thin-plate-energy of Loop surfacescan be evaluated precisely and efficiently, even though there areextraordinary points in the initial meshes, unlike the previous dynamicLoop surface scheme. Hence, the new method presented for Loop surfacesis much more efficient than the previous schemes.
