Abstract (en)
[origin: WO9202845A1] The method and apparatus function to form three-dimensional imagery on plural screen surfaces (2) which are formed by changing planes of imagery. One or more projectors (4) project a plurality of images onto the screen surface from a common axis. The planes of imagery on the screens (2) which are projected by said one or more projectors (4), change at such a speed that, to the eye, the images appear simultaneously in three-dimensional form on said screen surfaces (2).
