Abstract
The present invention permits realistic drawing of a natural shadow image, even when shadow images overlap each other on a background image, while preventing the shadow image from becoming darker in the superimposed area than in the other areas or preventing a decrease in the degree of translucence. The invention imparts a shadow object to each solid model to be drawn, determines whether shadow objects are superimposed from the positional relationship of the shadow objects imparted to the solid models to be drawn, and for an area where shadow objects are determined to be superimposed, the drawing process is executed by displaying only one of the superimposed shadow objects.
