PROBLEM TO BE SOLVED: To provide a game machine capable of suitably raising amusement of a player for display performance.SOLUTION: At a VDP 135, a geometry calculation including arrangement processing of image data to a world coordinate system is executed and rendering including projection processing to a projection plane is executed as well, for generating drawing data which is two-dimensional data. When sea-surface display performance is made, a sea-surface object is used as an object. The sea-surface object includes many pieces of surface data, and by setting color information according to orientation of the surface data, sea-surface display is made. Here, by using sea-surface animation data, an arrangement mode of respective surface data groups of the sea-surface object is determined. Further, by using first normal map data and second normal map data, an arrangement mode of respective surface data contained in the surface data groups is separately determined. |
