Abstract

We present a new method for simulating almost incompressible deformable objects. A tetrahedral model is used to represent and restore the volume during the simulation. A new constraint, which computes impulses in the one-ring of each vertex of the tetrahedral model, is used in order to conserve the initial volume. With different parameters, the presented method can handle a large variety of different deformation behaviors, ranging from stiff to large deformations and even plastic deformations. The algorithm is easy to implement and reduces the volume error to less than 1 percent in most situations, even when large deformations are applied.
