Abstract
It is determined, for each polygon, whether to perform an operation of calculating coordinate data of apices of the polygon, offset values of a display position of the polygon, and color data of the apices of the polygon on a coordinate system corresponding to a given display area based on coordinate data and color data of the apices of the polygon in a three-dimensional space, or an operation of calculating only the offset values of the display position of the polygon, and the determined operation is performed. Coordinate data of the apices of the polygon in the display area that are obtained by adding together the calculated offset values of the display position of the polygon and one of the calculated coordinate data of the apices of the polygon and the coordinate values of the apices of the polygon supplied from a memory are output, and one of the calculated color data of the apices of the polygon and the color data of the apices of the polygon supplied from the memory are also output. The polygon is rendered so as to correspond to the output coordinate data of the apices of the polygon and the output color data of the apices of the polygon in the display area.
