Display techniques to deal with viewpoint changes such as, so-called "pyramidic panel structures" are employed to adjust the image's vanishing point(s) in accordance with the movement of the user, such structures have the disadvantage that they work primarily for so-called "corridor-like" two-dimensional images. I have recognized that, in accordance with the principles of the invention, viewpoint changes may be also dealt with by partitioning the two-dimensional image into polygon partitions, each corresponding to a surface being depicted in the image, and then coupling the vertices of the polygon partitions with the movement of the user so as to limit distortions. In this latter approach, two-dimensional images are not treated as a perspective, corridor-like image, thereby allowing a wider variety of two- dimensional images to be used with the present invention.
