The history of computer animation began as early as the 1940s and 1950s, when people began to experiment with computer graphics - most notably by John Whitney. It was only by the early 1960s when digital computers had become widely established, that new avenues for innovative computer graphics blossomed. Initially, uses were mainly for scientific, engineering and other research purposes, but artistic experimentation began to make its appearance by the mid-1960s. By the mid-1970s, many such efforts were beginning to enter into public media. Much computer graphics at this time involved 2-dimensional imagery, though increasingly, as computer power improved, efforts to achieve 3-dimensional realism became the emphasis. By the late 1980s, photo-realistic 3D was beginning to appear in film movies, and by mid-1990s had developed to the point where 3D animation could be used for entire feature film production.

John Whitney, Sr was an American animator, composer and inventor, widely considered to be one of the fathers of computer animation.[1] In the 1940s and 1950s, he and his brother James created a series of experimental films made with a custom-built device based on old anti-aircraft analog computers (Kerrison Predictors) connected by servos to control the motion of lights and lit objects — the first example of motion control photography. One of Whitney's best known works from this early period was the animated title sequence from Alfred Hitchcock's 1958 film Vertigo,[2] which he collaborated on with graphic designer Saul Bass. In 1960, Whitney established his company Motion Graphics Inc, which largely focused on producing titles for film and television, while continuing further experimental works. In 1968, his pioneering motion control model photography was used on Stanley Kubrick's movie 2001: A Space Odyssey, and also for the slit-scan photography technique used in the film's "Star Gate" finale. All of John Whitney's sons (Michael, Mark and John Jr.) are also film-makers. John Whitney died in 1995.
