Stereo Optic Computer Presentations 870929

The advent of computers and their wide applications in Computer Aided Design (CAD) has renewed interest in 3D presentations. The ability of computers to allow work in 3D space has left the graphic presentations of that work behind in capability.
The Weingart Stereo-Optic imager, a new concept of 3D presentations, was introduced at SIGGRAPH '86 in Dallas by Weingart incorporated of Fort Wayne, Indiana. Each of the stereo optic pair is presented on a video monitor and the images are combined through a patented system of optics so that the user sees true stereo graphics while seated at a work station desk. Light losses are less than 25%, image detail is essentially that of the original image and the optics allow magnification of the CRT image by virtually any amount desired.
This paper surveys the history of stereo optics, the problems involved with computer based 3D graphics and the mechanical details of the Weingart system.
