Title: METHOD AND APPARATUS FOR PRESENTING 3-D MOTION PICTURES Inventors: William C. Shaw I. Graeme Ferguson Roman B. Kroitor Gordon W. Harris Ken T. Baker Paul D. Panabaker Marian F. Toporkiewicz A high fidelity 3-D immersion theatre experience is produced by alternately projecting corresponding lefteye and right-eye images onto a dome-shaped projection screen from two separate film strips and through separate wide-angle lenses. The lenses are positioned close together with their projection axes in a common vertical plane to achieve lateral co-incidence of the projected images and oriented in that plane to achieve vertical co-incidence of the images. Each person viewing the motion picture is provided with glasses that have lenses in the form of liquid crystal cells arranged to alternately block the left and right eyes of the person in synchronism with the projection of right-eye and left-eye images respectively, so that a stereoscopic effect is perceived.
