<P>PROBLEM TO BE SOLVED: To provide a game machine suitably enhancing the interest of a player in a display performance. <P>SOLUTION: A VDP 135 performs a geometry operation including arrangement processing of image data to a world coordinate system, and also performs rendering including projection processing onto a projection plane to create drawing data that are two-dimensional data. When a sea surface display performance is performed, an object for the sea surface is used as an object. The object for the sea surface includes a lot of surface data, and color information is set depending on directions of the surface data, thereby sea surface display is performed. In this case, an arrangement state of each surface data group of the object for the sea surface is determined by using animation data for the sea surface, and furthermore, an arrangement state of each piece of surface data included in the surface data group is individually determined by using first normal line map data and second normal line map data. <P>COPYRIGHT: (C)2012,JPO&INPIT |
