A high quality, yet cost effective system for creating special effects in full natural widescreen 3-D theatrical motion pictures has been developed and proven in actual use. This usage was in a production released in 3-D by a major studio distributor. This unique system offers the economies of single-film single-camera production. At the same time, it provides the quality and high resolution of a large film area, along with the versatility of variable convergence and a variable stereo base (variable interaxial). This system uses prime lenses or zoom lenses, including macro and telephoto lenses. It can be used for animation, aerials, miniatures, blue screen, live action closeups, process projection, rotoscoping, and many other types of special effects work in 3-D. Motion control effects may be achieved in a single pass. There are no polarizers or beamsplitters in the system, so there is very little light loss. Video and computer CRT images in full 3-D are additional valuable capabilities.
