We propose a method of skeleton generation for 3D models. The proposed method works in real time. It consists of five steps: 1) transformation into the low polygon model from the original model that composed a large number of polygons, 2) calculation of the sum of geodesic distances from specific points to all vertices on the 3D model, 3) subdivision of the 3D model using the sum of geodesic distances, 4) generation of skeleton joints (skeleton node) on the each boundary surface between those subdivision areas, and 5) connection of each skeleton nodes. We also propose the method for flexible skeleton generation using boundary shapes and the sum of geodesic distances. By using this method, the skeletons can be generated in the area where the user specified. Accordingly, it is expected that user can create flexible animations of 3D models in real time.
