of Simulation Techniques For Deformable Animated Characters by Remco K. Chang, Sc. M., Brown University, April 2000. This thesis surveys three different deformation models for physically based simulation. The ability to model and manipulate deformable objects is essential to many computer graphics applications, especially in modeling and simulation of realistic and complex environments. Approaches for modeling object deformation, however, have been constrained by the limi tation of hardware. Although realistic behavior of the deformed objects is most desirable, many methods sacrifice the realism for speed. The three deformation models that we survey are based on individual nodal point anal ysis, a reduced degree of freedom model, and an approximate continuum model, each with its own strengths and weaknesses. We examine these deformation models using the same set of parameters, and measure their performance in terms of speed, stability, and robustness.
