Dynamic Surface Deformation and Modeling Using Rubber Sweepers

We introduce a new surface deformation and modeling method in this paper. Referring to the swept volume generation, the surface is pulled or pushed along a trajectory curve. The key point is the sweeping function. Surface points are moved to where they should be during sweeping operations according to the global parameter, which is determined by topological distance. An index factor controls how much the surface deforms around the handle point. The proposed method is easy to extend to fit different applications such as various constraints, local deformation and animations.
