So now I will show a short video of two of my models being deformed in an interactive simulation environment. Each model is created with two interior layers, a rigid bone core and a layer of deformable skin.

In both examples the user controls a tool to rotate the internal bone core of the object. The ears and the loose skin covering the core deform dynamically in response to this motion.

The video shows a high-resolution textured surface that is animated by the results of the simulation on the low resolution tetrahedral mesh.

The animated head of the bunny contains about approximately 300 bone tetrahedra and 850 skin tetrahedra. The dog model consists of approximately 2,000 tetrahedra, of which 1200 are skin tetrahedra animated by the simulation.

The interactive system was a joint effort with Rob Jagnow and Matthias Mueller. The deformation algorithm was developed by Matthias.
