Abstract:
We investigate techniques for modeling contact between quasi-rigid objects – solids that undergo modest deformation
in the vicinity of a contact, while the overall object still preserves its basic shape. The quasi-rigid model combines
the benefits of rigid body models for dynamic simulation and the benefits of deformable models for resolving
contacts and producing visible deformations. We argue that point cloud surface representations are advantageous
for modeling rapidly varying, wide area contacts. Using multi-level computations based on point primitives, we
obtain a scalable system that efficiently handles complex contact configurations, even for high-resolution models
obtained from laser range scans. Our method computes consistent and realistic contact surfacesand traction
distributions, which are useful in many applications.
