PROBLEM TO BE SOLVED: To provide a game machine capable of displaying a gradually disappearing three-dimensional image with comparatively simple processing. SOLUTION: A polygon is disposed within a world coordinate system, and the state of observing the polygon from a predetermined visual point is displayed. When displaying an image G of the polygon, the polygon is projected on a projection plane set based on the visual point, and a texture deformed to the shape of the projected polygon is plotted. The texture is provided with non-displayed portions, and a plurality of kinds of mask patterns for making the image of the texture disappear by the change of the non-displayed portions are applied to the texture after deformed to the shape of the polygon. The image G of the polygon formed by sequentially sticking the textures thereon is thereby displayed to gradually disappear on a display screen 6a. COPYRIGHT: (C)2011,JPO&INPIT
