Non-uniform Differential Mesh Deformation [chapter]

Dong Xu, Hongxin Zhang, Hujun Bao
2006 Lecture Notes in Computer Science  
Based on these two methods, we implement a multiresolution deformation tool, which allow the user to edit a mesh inside a hierarchy in a material-aware manner.  ...  The non-uniform deformation is achieved by material-dependent gradient field manipulation and Poisson-based reconstruction.  ...  In particular, surface details can be well preserved during the deformation, and in a material-aware manner.  ...
