摘要 |
A partial shadow volume having a predetermined height defined by a contour of a character object and light coming from a light source is formed based on undulations of a land object, and is then stored in advance in a DVD-ROM (300) or the like. A CPU (10) reads this partial shadow volume for placing the partial shadow volume at a point of intersection of the land object and a line extending from character object placement coordinates to a light direction. The placed partial shadow volume is rendered by using the stencil buffer (16). Based on values in the stencil buffer (16), a shadow of the character object cast on the land object is rendered. Thus, a realistic shadow can be rendered with processing load required for shadow rendering processing being reduced. |
