1. A method of generating an image to simulate a view seen by an observer within an imaginary space, comprising the steps of: (1) mapping at least a portion of a panoramic view of a first surface to be simulated in the imaginary space onto a second mapping surface by providing as picture elements the picture values of areas of said mapping surface corresponding to areas of said first surface projected onto said mapping surface; (2) storing said picture elements on a storage medium as a panoramic image; (3) retrieving from said storage medium a portion of said picture elements as a function of the position and orientation of an observer with respect to the imaginary space; and (4) displaying said plurality of picture element on a display.
