Patent ID: 6980214

Claim:
A computer-readable storage medium storing a program for a video game, which draws an object in a virtual space, wherein said program is structured so as to make a computer perform: receiving object data representing an object at a particular instance of a virtual time-space continuum; generating a dummy object of said object, the dummy object having an identical shape of said object, by duplicating said object data; determining a first position of said object and a second position of said dummy object so that said dummy object thus generated is positioned behind said object and overlaps only in part with said object when observed from a view point, the orientation of said dummy object being the same as that of said object; and drawing, in a digital video frame representing said instance of said virtual time-space continuum, said object at said first position and drawing said dummy object at said second position except for an overlapping portion between said object and said dummy object when observed from the view point and wherein the drawing of said dummy object is in a second lightness different from a first lightness of said object, said second lightness being based on said first lightness.
