Patent 7173618 was granted and assigned to Nintendo on February, 2007 by the United States Patent and Trademark Office.
A character object 2001 which stands on a ground in a virtual space is arranged to rise on a land object 1802. Here, the character object 2001 is arranged to look towards a side of a virtual camera 1601. Further, the land object 1802 is arranged so as to be displaced a predetermined distance from its original position along a direction of the orientation of the virtual camera 1601 and in a direction away from the virtual camera 1601. This prevents a character arranged on a ground in a 3D virtual space from being displayed as if a part of the character sank into the ground.
