Abstract: A method of producing three-dimensional imagery including displaying on a screen surface, imagery containing two or more spaced apart angles of view about a common centre of a subject of the imagery; and which angles of view have been segmented and separated; the segmented and separated angles of view being viewed through sections of a grid, of a size and shape corresponding substantially to the dimensions of the segments of imagery; the grid being placed at a distance from the screen where segments of imagery acquired left of the common image centre are seen through sections of the grid substantially by the left eye of the viewer, while segments of imagery acquired right of the common image centre are seen through grid sections substantially by the right eye of the viewer; the relationship of left and right segments of imagery, relative to the grid sections, being maintained when the imagery is displayed on the screen, by oscillation of the grid sections in synchronisation with an alternating display of alte

Abstract: 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).
