Three-Dimensional Computer Display.

A stereographic display terminal has been produced using the raster display (BRAD) recently developed at Brookhaven. The system uses a rotating refresh memory to feed standard television monitors. To produce a stereographic display the computer calculates the projected video images of an object, viewed from two separated paints. The resulting video maps are stored on separate refresh bands of the rotating memory. The two output signals are connected to separate color guns of a color television monitor, thus creating superimposed image on the screen. Optical separation is achieved by viewing the image through color filters. The display is interactive and can be viewed by a large group of people at the same time. [ABSTRACT FROM AUTHOR]
