ABSTRACT:
An information setting section sets positional information of a point on each polygon to express the positions of polygons in each of a plurality of surfaces which is represented by a plurality of segmented polygons. A plurality of radiosity maps are set in association with a plurality of surfaces, and pixel values representing the radiosity maps are stored in association with the positional information of the individual polygons set by the information setting section. A map referring/drawing section reads the pixel value representing the radiosity map corresponding to each positional information stored in the radiosity map corresponding to each surface to form a radiosity image.
