Abstract
Abstract A method of viewing a three dimensional display and structure therefor which comprises providing a three dimensional display, providing a projection surface which is a sector of a substantial spheroid, providing projection optics projecting the three dimensional display onto the projection surface and placing an observer within the substantial spheroid. In accordance with a second embodiment there is provided a method of viewing a three dimensional display comprising providing a double parabolic mirror, providing a three dimensional display within the double parabolic mirror, projecting an image of the three dimensional display external of the parabolic mirror and viewing the image from a location external of the double parabolic mirror.
