摘要

Both legs of a human figure P are each formed by two skeletons SK1, SK2 (SK3, SK4). A dynamic model is formed by a mass particle W located at a waist position A, an elastic body SP such as a spring coupling the mass particle W and a middle point B between the feet of both legs of the human figure P, and a damper DP. The positions of the skeletons SK1 to SK2 forming the legs can be dynamically obtained by calculating the waist position and further the positions of the knees using the dynamic model. Accordingly, movements of the legs can be expressed in such a manner as to give a good presence by dynamically calculating them every scene displayed as a game progresses.
