Abstract

This paper proposes an example-based linear blend skinning system that incorporates the torques applied to the skeletal joints. For this purpose, deformation gradient predictors are trained using a set of examples with the minimum torque and another set with the maximum torque. The run-time algorithm takes an animated skeleton and joint torques as input. It computes the deformation gradients from the predictors. They are then combined with torque-based blending functions. The functions are trained at the preprocessing stage using a set of skeleton-mesh-torque examples with the aid of statistical analysis. The experimental results show that the proposed system runs at real-time and produces quite realistic skinned meshes based on the input torques.
