One of the First Computer-Generated Films, from 1963 - AT&T Archives 

A short, simple 3D animation of a satellite object orbiting a globe:

This film was a specific project to define how a particular type of satellite would move through space. Edward E. Zajac made, and narrated, the film, which is considered to be possibly the very first computer graphics film ever. Zajac programmed the calculations in FORTRAN, then used a program written by Zajac’s colleague, Frank Sinden, called ORBIT. The original computations were fed into the computer via punch cards, then the output was printed onto microfilm using the General Dynamics Electronics Stromberg-Carlson 4020 microfilm recorder. All computer processing was done on an IBM 7090 or 7094 series computer.

Zajac didn’t make the film to demonstrate computer graphics, however. Instead, he was interested in real-time modeling of a certain theoretical construct. At the time, The Bell System was still deeply engaged in satellite research, having launched Telstar the previous year, with plans to continue developing communications satellites. Zajac’s model is of a box (“satellite”), with two gyroscopes within. In the film, he was trying to create a simulation of movement — the pitch, roll, and yaw within that system.

Action, Now! #19

New York — Nuns of the New York Roman Catholic Archdiocese march in orderly lines through the streets of Harlem during a mass demonstration of support for civil rights workers in Selma, AL. Some 300 nuns marched in the demonstration, which included more than 10,000 persons marching up Seventh Avenue, one of the main thoroughfares of the nation’s largest Negro community. (1965)
