VIRTUAL REALITY SIMULATOR AND VIRTUAL REALITY SIMULATION PROGRAM

A VR (Virtual Reality) simulator acquires a virtual space image by imaging a virtual space from a virtual user position corresponding to a real user position. The YR simulator draws the virtual space image on a curved screen installed at a position distant from a user. A virtual screen position in a virtual space corresponds to the installation position of the curved screen. An inverse curved screen is placed at the virtual screen position and curved inversely to the curved screen. The VR simulator acquires a first virtual space image by imaging the virtual space from the virtual user position, and draws the first virtual space image on the inverse curved screen. Further, the YR simulator acquires a second virtual space image by imaging the first virtual space image on the inverse curved screen from the virtual user position, and draws the second virtual space image on the curved screen.
