PROBLEM TO BE SOLVED: To provide a game machine capable of displaying gradually disappearing three-dimensional images by a relatively simple processing. SOLUTION: A polygon is arranged inside a world coordinate system and the situation of observing the polygon from a given view point is displayed. At the time of displaying the image G of the polygon, the polygon is projected on a projection plane set based on the view point and a texture deformed matched with the shape of the projected polygon is plotted. In this case, the texture is provided with a non-display part and the plural kinds of masking patterns for changing the non-display part and making the image of the texture disappear are made to act on the texture deformed matched with the shape of the polygon. Thus, the image G of the polygon generated by successively sticking the textures is displayed so as to gradually disappear on a display screen 6a. |
