PROBLEM TO BE SOLVED: To provide a three-dimensional game device and an information storage medium capable of attaining the soft shape deformation of an object while holding the real time property of processing. SOLUTION: The directional information θ1 of a virtual skeleton 44 is changed. The positional information of vertexes b0 to b3 of a polygon is found based on the positional information of unchanged vertexes b0' to b3', the directional information θ1 (the positional information of vertexes b0" to b3" found out by the θ1) of the skeleton 44 and influence degree information from the skeleton 44 and a master virtual skeleton 42. Processing for finding luminance information is similarly executed. Provided that it is also available to directly interpolate the luminance information without executing the synthetic processing of normal vectors. As to a vertex list and a normal list respectively storing the vertex position information and normal information, data including influence degree information are arranged on the head side. It is desirable to use the weighted value of influence degree information between the slave and master virtual skeletons 44, 42. In addition to joints, the movement of hair and changes of skin can be expressed. |
