Human body deformations using joint-dependent local operators and finite-element theory

摘要

This paper discusses the problem of improving the realism of motion not from the joint point-ofview as for robots, but in relation to the deformations of human bodies during animation. Two methods for improving these deformations are described. The Joint-dependent Local Deformation (JLD) approach is convenient when there is no contact between the human being and the environment. A finite element method is used to model the deformations of human flesh due to flexion of members and/or contact with objects.
