In this paper, we propose an example-driven approach to transfer deformation from source meshes to a target character based on sketch. Our approach consists of the following steps: (a) a sketch based mapping between parts of the sources and corresponding portions of the target; (b) deforming the portions of the target based on the deformations of the corresponding parts of the sources by means of differential mean value coordinates; (c) stitching the deformed portions of the target together smoothly by minimization to form a key frame of the target animation. We provide new research contributions on all these topics, and integrate them into our newly developed prototype animating system. Our approach is general and does not require the sources and target to share the same number of vertices or triangles, or to have matching connectivity. Our approach is intuitive and is able to produce highly authentic 3D animations. We demonstrate our approach by constructing several animating examples produced from our prototype system.
