Displays on Display

Although the use of raster graphics technology has increased considerably during the past few years, in many applications vector devices still produce the highest quality pictures. This issue´s displays on display were designed and generated by Melvin L. Prueitt at the Los Alamos National Laboratory on an Information International FR-80 computer-output-to-microfilm system, which draws vectors on a white phosphor CRT. Color is applied by means of red, green, and blue filters.
