A polygon of a skirt is beforehand set in association with a skirt bone such that the polygon is at an angle of beta to the skirt bone. The movement of the skirt bone is controlled according to the movement of a thigh bone. When a character walks or runs, if the thigh bone is inclined at an angle of alpha, each of the skirt bone and the polygon is inclined at an angle of alpha in a direction perpendicular to the ground surface. Therefore, since a polygon and the polygon do not interest each other, it is possible to prevent a thigh portion of the character from penetrating the skirt unnaturally. |
