Soft Tissue Simulation for Computer Animation of Vertebrates

Frequent topic of current research studies and commercial applications is a modeling, animation and simulation of various parts of a human body. A biomedical applications in this area usually focuses in small part of a bod (selected organ) and simulates its functionality with high degree of accuracy using complex models. On the contrary the computer animation concentrates on simplicity of the model and high computing speed. Usually so called ``inverse solution'' to the motion description is used. The animator defines the trajectory of selected parts of the model; from such motion description the resulting muscle, fatty tissue and finally skin deformations are computed.
