METHODS AND APPARATUS FOR RENDERING AN IMAGE INCLUDING PORTIONS SEEN THROUGH ONE OR MORE OBJECTS OF THE IMAGE

Surfaces of an object are rendered in the order from a surface remotest from a viewpoint. When a rear surface, e.g., a rear surface, is to be rendered, a range, i.e., a range of a texture to be used, projected by way of perspective projection with vectors which are directed from the viewpoint toward a background image and take into account refractions at vertexes of the surface is determined, and the texture in the determined range is mapped onto the surface. When a front surface, e.g., a front surface, is to be rendered, a range, i.e., a range of a texture to be used, projected by way of perspective projection with vectors which are directed from the viewpoint toward a background image and take into account refractions at vertexes of the surface is determined, and the texture in the determined range is mapped onto the surface.
