Abstract: Deformation animations between different computer-generated characters or objects have gained widespread attention in the recent years. In movie and gaming industries, deformation animations between different objects create breath-taking effects. In cartoon shows, computergenerated anthropomorphized characters are animated to tell a story. In the current work, a simple and efficient algorithm for deformation between objects of greatly dissimilar shapes, which does not require any form of similarity or vertex correspondence mapping, is presented. This deformation algorithm is called general skin deformation algorithm, because all intermediate shapes are represented by a maximum curvature continuous surface type called skin surface. All intermediate skin surfaces share the same Voronoi complex, which is called the intermediate Voronoi complex. The Minkowski sum of the intermediate Voronoi complex and its dual Delaunay complex forms mixed cells which cut skin surfaces into patches. These skin patches are free to deform in their own mixed cells according to regular sphere or hyperboloid functions.
