PROBLEM TO BE SOLVED: To simply and really display a thin plate-like model simulatively expressing an object like a thin plate. SOLUTION: A bottom wall polygon selection part 72 selects a rugged polygon set 422 as a polygon set constituting a bottom wall model when a point of view is upper than a polygon set for a water surface. When the polygon set 422 is selected, a polygon movement control part 73 instructs a moving distance to be moved during the lapse of prescribed time T to a graphics data generation processor 3. A texture displacement control part 74 instructs a plotting processor 10 to displace the attaching coordinates of a bottom wall texture 52 for the polygon set 422 only by the moving distance in the reverse direction at each prescribed time T.
