Abstract
We propose a 3d model deformation technique, which is based on rigging by building the skeleton of the model by user. The approach not only achieves the detail-preservation, but also derives more natural deformation by adding several high-level constraints for more natural results of mesh deformation. The above constraints include preserving the length of bones, limitation of joint angle, and rigidity. Users can modify the pose of a model by direct manipulation on skeleton, and get the realistic deformed mesh. We optimize a given energy function according to the position and weight of skeletons. Our results show the following advantages: convenience of manipulation on rigging and deformation, high-level constraints, and more natural and realistic deformed mesh. Our research is inspired by a research paper done by Kun Zhou et al. in Microsoft Research Asia.
