Archive film showing possibly the first example of digital rendering, made by Pixar co-founders Ed Catmull and Fred Parke in 1972, was stumbled upon by the son of Robert B Ingebretsen, who also set up the world-famous U.S. studio. A six minute version shows additional CGI animation of an artificial heart valve, and human heads.
A Computer Animated Hand (1972) is currently not available on any services.
