PROBLEM TO BE SOLVED: To freely control a computer graphics(CG) model in real time by correcting the reference position of the CG model in a vertical direction so as to bring the part at the lowest position of the vertical direction in a virtual space of the CG model into contact with a reference surface in the virtual space at all times. SOLUTION: Relating to the CG model provided with a skeleton structure, the position and posture, etc., of the respective parts are obtained when the coordinate value of master parts and respective joint angles or the position of a joint are supplied, however, the master coordinate value is normally set to the position of the waist or the pelvis, and in the case of bending the knee or the like, an unnatural motion that the toe is floated in the air is generated when no processing is added to the master coordinate value. Then, a recording/editing part decides the foot of a smaller distance YL or distance YR between the toe and a floor surface as a pivoting foot and corrects the position in the vertical direction of the model so as to bring the tip of the pivoting foot into contact with the floor surface at all times. Also, in the case that the pivoting foot in contact with a floor is moved in a horizontal direction, the position in the horizontal direction of the model is corrected so as not to move the pivoting foot. |
