PROBLEM TO BE SOLVED: To realize an effective display technique even other than the so-called 'corridor-like' two-dimensional image such as a road in the integration of a three-dimensional computer graphic and a two-dimensional image in order to provide a three-dimensional virtual reality (virtual reality experience. SOLUTION: Viewpoing change is processed by two-dimensional polygon division. Each polygon corresponds to a plotted surface in the image, and a polygon vertex is connected to user movement so as to limit distortion. Concretely, an image point that is far away from a user's viewpoint plane (view plane) is moved while closely connected with the movement of a user's current viewpoint. When a viewer moves so as to separate from the ideal viewpoint (IVP: ideal viewing point) of the image in this way, image distortion caused by the movement reacts so as to suppress the distortion. |
