= CGI History = This article is about CGI, and how computer generated imagery has shaped movies, television shows, and the film industry from the early 1960s to 2022.

Computer animation is the process used for generating animated images. The more general term computer-generated imagery (CGI) uses both static scenes and dynamic images, while computer animation only refers to the moving images. Modern computer animation usually uses 3D computer graphics, although 2D computer graphics are still used for stylistic, low bandwidth, and faster real-time renderings. Sometimes, the target of the animation is the computer itself, but sometimes film as well. The technology is also used to advertise, architecture, engineering, virtual reality, and art.

First Animations & Films using CGI
One of the first ever computer animations was used by Alfred Hitchcock, called Vertigo in 1958. It was a 2D images that show a series of spirals that expand and shrink when looking at them, often referred to as Lenticular printing. The second animation was crafted in 1972, A computer generated hand. The hand was created by Ed Catmull, one the founders of Pixar at the University of Utah. It was one of twenty-five new additions added to the US film archive. In 1967 the first digital morphing of a face was born. Sine Curve Man, created a smooth transition from one face to another. It was created by Mark Gillenson, using a sine curve map on a mainframe computer (IBM 360). The first most popular use of the application was in Michael Jackson's music video, Black or White.

First Use of Digital Animation and Live Action in a Film
West world was the first film to use CGI in a live action film, John Whitney Jr., and Gary Demos collaborated to produce a robots, Gunslinger, point of view of the world. It was accomplished with the use of 2d CGI. Block portraiture was accomplished using the Technicolor Three-Strip Process to color-separate each frame of the source images, then scanning them to convert into rectangular blocks according to its tone values, and finally outputting the result back to film. The CGI was so popular that they used it again in a sequel Future world in 1976, that movie also produced ground-breaking CGI, because they produced a 3D head.

First film to be completely CGI
The first movie from the Toy Story series was the first feature-length film made entirely with CGI animation. The movie took 4 years to make, it used 300 computer processors, and took 800,000 machine hours to make. This was the first film from Pixar Animation Studios, and then a California-based CGI computer animation company, Pixar, went on to make many groundbreaking films with Disney. With later films being Monsters Inc, Finding Nemo, etc. The Polar Express was the first film to use motion-captured character technology for every single actor in the movie.
