ABSTRACT:
In a virtual reality system (20) an operator perceives being in a virtual reality world (74) of virtual reality images (62). The system (20) models the relative position and movement of objects (208 and 210) in a virtual reality world (74) by representing graphically a first (208) and second (210) object in a virtual reality world (74) on a graphical display (60 and 68). The representation selective obscures the first (208) and second (210) objects according to the relative position of the objects (208 and 210) to a predetermined observation point in the virtual reality world (74). The system (20) then determines a first partitioning plane (204) between the first (208) and second (210) objects. Then, the system (20) method determines a second partition plane (206) between the first (208) and second (210) object in response to either of said first (208) or second (210) objects moving across the first partitioning plane (204). Then, the system (20) graphically represent on the graphical display (60 and 68) the first (208) and second (210) objects within the virtual reality world (74) by selectively obscuring the first (208) and second (210) objects according to their relative position to the predetermined observation point.
