That film has been digitized and is available on http://nerdplusart.com/first-3d-rendered-film-from-1972-and-my-visit-to-pixar . All kinds of modern techniques like gouraud shading, deformed meshes, and z-buffering are shown in the film. There is a segment showing Catmull digitizing a plaster model of his hand. Catmull later founded Pixar, but at the time the Utah lab pioneered many of the graphics techniques we take for granted today."
