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 human hand rendered in real time at minimal cost to the main CPU.
In related work, we showed how multizone elastostatic structures can be efficiently simulated using an efficient form of domain decomposition.
