Inertial Damping for Enhanced Simulation of Elastic Bodies

Abstract

Inertial damping is used to improve the simulation of deformable bodies for physics-based animation. Using this technique, undesirable dynamics of deformable bodies can be suppressed or completely removed while retaining other, more desirable dynamics. An inertial damping module selectively applies inertial damping to a subset of the dynamic modes of a simulated system (e.g., by using the quasi-static solution for these modes or reducing their magnitude). Thus, when the dynamics are simulated, the interactions between modes can be retained while the undesirable effects of the damped modes are reduced or eliminated. The results of the simulation are used to drive a physics-based animation.
