Abstract
The present invention detects polygons located in a region of diffused light or specular light, divides that polygon and generates subdivided polygons, and for those polygons, carries out lighting processing and rendering processing using linear interpolation according to the conventional Gouraud shading method. In consideration of the efficiency of the image processing, the present invention does not subdivide all the polygons, but rather subdivides the polygons located within the area of diffused light or specular light. Or, the present invention subdivides only those polygons located within areas where the intensity of the diffused light or specular light varies.
