A Computer Animated Hand (1972)
Ed Catmull, co-founder of Pixar Animation Studios, renowned for its CGI (computer generated image) animated films, created a program for digitally animating a human hand in 1972 as a graduate student project, one of the earliest examples of 3D computer animation. The one-minute film displays the hand turning, opening and closing, pointing at the viewer, and flexing its fingers, ending with a shot that seemingly travels up inside the hand. In creating the film, which was incorporated into the 1976 film “Futureworld,” Catmull worked out concepts that become the foundation for computer graphics that followed.
