To solve the problem relative to non-animation caused by application of hidden surface processing or environmental mapping to a plurality of polygons or models (objects) constituting a realistic virtual stereoscopic image formed by a conventional 3D operation processing, and the thereby enable 3D image representation as animation representation without damaging the atmosphere of a picture as an animation.
In the plurality of objects or polygons arranged in a world coordinate, objects or polygons to which the environmental mapping or the hidden surface processing is applied and objects or polygons to which the environmental mapping or the hidden surface processing is not applied exist. The hidden surface can be applied forcibly on the game production side to the object or polygon to which the environmental mapping or the hidden surface processing is not applied, without applying the hidden surface processing by operation processing of a light source or the like, by being composed with another same object or polygon on which a texture having only shade and transparency information prepared beforehand is mapped.
