Abstract
We propose a method for real time creation of 3D animation for 3D characters on the web. As our preliminary attempt, we build and discuss the method for real time skeleton extraction using object data of those 3D characters. Our method consists five steps of transformation into the low polygon model from the object data that composed a large number of polygons, calculation of the sum of geodesic distances from some of the vertices to all vertices on the object data, subdivision of the object data using those geodesic distances, generation of skeleton joints (skeleton node) on the each boundary surface between those subdivision areas, and connection of each skeleton nodes. According to our method, the skeletons from the object data that composed a large number of polygons could extract in real time.
