We developed a technique, called EigenSkin, for real-time quasi-static deformation of articulated soft bodies such as human and robot hands. The deformations are compactly approximated by data-dependent eigenbases which are optimized for real time rendering with vertex programs on commodity graphics hardware. Animation results are presented for a very large nonlinear finite element model of […]
A long standing challenge had been fast simulation of realistic soft body dynamics, a computationally expensive task. In 2002, when the programmable graphics processor (GPU) was first introduced, we showed how precomputed modal deformation models could be efficiently mapped onto such massively parallel architectures with negligible main CPU costs. The precomputation is stored as a […]
We developed a general framework for low-latency simulation of large linear elastostatic deformable models, suitable for real time animation and haptic interaction in virtual environments. The deformation is described using precomputed Green’s functions, and runtime boundary value problems are solved using Capacitance Matrix Algorithms. We introduced boundary element (BEM) techniques for precomputing Green’s functions, and […]
Starting around 1998, we developed the UBC ACtive MEasurement facility (ACME), a telerobotic system for capturing comprehensive computer models of physical interaction behavior of real 3D objects. The behaviors we could successfully scan and model include deformation response, contact textures for interaction with force-feedback, and contact sounds. We also developed a novel software architecture for […]
