This paper presents a new methodology for constructing an example-based skin deformation model of human forearm based on MRI images. Generating realistic skin animation of forearm movement is generally difficult in CG domain because there is a crucial difference between a structure of forearm of a virtual human and a real human. So we propose a new kind of skin deformation model based on MRI images. Using MRI images, we can model example skin shapes associated with location of bones with accuracy. We also mention how to apply the model to characters to generate skin animation. For this purpose, we employ RBF, Radial Basis Functions. Once the model is constructed, skin animation is easily generated by applying the model to the forearm of a character by means of RBF. In this paper, we describe how to construct our model, first. Then we explain the method to apply the model to characters and generate skin animation.
