Computer-Made Perspective Movies as a Scientific and Communication Tool* It is easy to program the basic transformation required for a perspective drawing. This fact plus the advent of high speed microfilm printers such as the General Dynamics Electronics S-C 4020 makes possible perspective movies as the direct output from a computer. The programming of such a movie is briefly described for studying the angular motions of a satellite containing an attitude control system. In the movie, a domino-shaped box represents the satellite and a sphere with circles of latitude and longitude represents the earth. The cost was approximately three to eight minutes of IBM 7090 time per one minute of movie. CACM March, 1964 Zajac, E. E. CA640319 JB March 10, 1978 2:26 AM 1113 5 1113 1113 5 1113 1113 5 1113
