When was the first computer animation created? It's hard to pin point the exact one, given there were several companies that were dabbling in it during that time. AT&T, and others, believe that this clip dating back to 1963 could be the first.
The animated clip isn't that great, compared to what we've got today, but its creator, Edward E. Zajac, narrating the video, was trying to model and simulate the motions of a satellite orbiting the planet, and the animation is a result of a wireframe rectangle circling a wireframe sphere. Back then, this was the best kind of presentation anyone could do.
Programmed in FORTRAN in a time when punch cards were still the norm, and 'rendered' on old IBM 7090 and 7094 computers, it was not shown a screen after that. Instead it was printed, frame by frame onto microfilm where they could watch it in real time via a projector.
