VR motion base control apparatus and it's supporting structure

The present invention is related to a control by a synchronization system between a picture and a motion base in a simulation ride system for moving the motion base in connection with the picture. A VR motion producing apparatus includes a dynamic object to be controlled, a motion base having a finite stroke and motion model converting means for converting in a real time a motion model of a dynamic object to be controlled which is moved within a virtual reality space constituted by computer graphics into another motion model of the motion base having a finite stroke. The motion model converting means includes means for converting coordinate data of the motion model of a dynamic object to be controlled into coordinate data of the motion model of the motion base.
