Abstract:
A fishing game device comprising:a display unit; a control unit for converting into two dimensional coordinates data for objects having three-dimensional coordinates in a three-dimensional virtual space and controlling the display of images of the objects on the display unit, said objects including a fish; a memory component for storing data for said fish moving about within the three-dimensional virtual space; a simulated fishing rod manipulated by a player; and a sensing element for sensing movements of the simulated fishing rod manipulated by the player, wherein the control unit establishes camera viewpoint on the basis of a specific relationship to the coordinates of the object in a three-dimensional coordinate system and controls the display unit so as to display image data produced through projection of the object, as viewed from the camera viewpoint, onto a two-dimensional plane, and wherein the object coordinates and camera viewpoint coordinates maintained in a specific relationship to the object coordinates are updated in response to movements of the simulated fishing rod sensed by the sensing element, and wherein the control unit modifies the fish data over time or in response to motion of the simulated fishing rod sensed by the sensing element and stores the modified data in the memory component.
