| Abstract | Muscle is the fundamental “motor ” that drives all animal motion. We propose that changes in shape of moving hu-man and animal figures will be accurately reproduced by simulating the muscle action and resulting forces that propel these figures. To test this hypothesis, we developed a novel computational model of skeletal muscle. The geometry and underlying material properties of muscle are captured using the finite element method (FEM). A biomechanical model of muscle action is used to apply non-linear forces to the finite element mesh nodes. We have tried to validate the FEM model by simulating well known muscle experiments and plotting out key quantities. Our results indicate that the twin goals of realistic computer animation and valid biome-chanical simulation of muscle can be met using these meth-ods, providing a principled foundation both for animators wishing to create anatomically based characters and biome-chanical engineers interested in studying muscle function. |
