Skeleton Driven Limb Animation Based on Three-Layered Structure.

In this paper, we present a new model for the skeleton driven limb animation, which is composed of three layers: linear bones, volumetric bones and coarse volumetric control lattice. Volumetric bones are driven by linear bones using geometric method and the coarse volumetric control lattice is driven by volumetric bones using finite element method. In order to compute faster, we perform linearized simulations. The limb is embedded in the volumetric control lattice, and the surface of limb is computed using linear interpolation method. PCG solver is used to solve the large linear system of equations. We can obtain realtime simulations and realize the motions such as bend and torsion of limb. [ABSTRACT FROM AUTHOR]
