In a real-time texture mapping system, a more solid and naturally-mapped image is obtained with a minimum of computation volume. The texture-mapping system adds a texture image to an area of a polygon which forms a fundamental unit of three-dimensional image information of an object to be displayed on a screen. A geometry transfer engine (GTE) 61 extracts representing points from the polygonal area. Then, coordinates of the thus extracted representing points are subjected to the perspective transformation. Thereafter, the representing points, after the perspective transformation, are subjected to the linear interpolation in a graphic processing unit (GPU) 62 so that the image is formed.
