A primary polygon is processed to generate new secondary polygons utilizing a light source as a base point. A front-side secondary polygon is selected from the secondary polygons and drawn in a blackish color by rendering and hidden surface removal utilizing Z-buffering. Then, back-side secondary polygons are drawn by rendering and hidden surface removal utilizing Z-buffering such that the blackish color in portions of the front-side secondary polygon is eliminated, making these portions transparent.
