ABSTRACT
Figure 12.1. Real-time soft body simulation using strain based dynamics showing several frames from the deformation of the Stanford bunny dataset.
Stress and strain values are evaluated, and anisotropic behavior is introduced by augmenting additional stress and strain coefficients. This chapter provides a simple and straightforward implementation of strain based dynamics for both surface (cloth) and mesh models (tetrahedral mesh). A snapshot from an implementation of the technique described in this chapter is shown in Figure 12.1.
