Abstract:
Meshless deformation based on shape matching is a new technique for simulating deformable objects without
requiring mesh connectivity information. The approach focuses on speed, ease of use and stability at the expense of physical accuracy. In this paper we introduce improvements to the technique that increase physical realism and make it more suitable for use in interactive real-time environments such as games and virtual surgery applications. We also present intuitive real-time interaction techniques for picking, pushing and cutting objects simulated using meshless deformation based on shape matching. For deformable collision detection and response, we present a new method for surface meshes based on previous volumetric methods.
