Abstract: A polygon of a skirt is beforehand set in association with a skirt bone such that the polygon is at an angle of ? 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 ?, each of the skirt bone and the polygon is inclined at an angle of ? 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.

Abstract: When a predetermined condition is satisfied in a game and a scenario mode is started, a predetermined scenario is displayed. When an animation in the scenario is completely displayed, a transmission waiting state is started and idling of a character displayed on a display screen is displayed. The idling display is performed based on the pose of the character in the transmission waiting state. The idling display is performed by deciding the angle of a target pose based on difference information of a joint management table.
