PROBLEM TO BE SOLVED: To control a display so as to be easily watched without a sense of incongruity when an aspect of an object in a virtual space is displayed as an image. SOLUTION: A contact decision between a field object and other object is performed, and a coordinate of a vertex which is decided to be in contact out of vertexes of the field object is updated. A light source set in the virtual space is increased and decreased on the basis of at least a positional relation between a virtual camera and the light source. A source of the virtual energy (referred asαlight hereinafter) for affecting transparency provided with a same characteristic as light (referred as anαlight source hereinafter) is arranged in the virtual space, and the transparency of the object is determined on the basis of luminance of theαlight on the object in the virtual space. A texture is determined on the basis of an environment mapping algorism with respect to a light source object which models a light source and/or a ray object which models a ray.
