Computer-generated imagery is the most popular and most developed form of animation. It has revolutionised animation in a way that we can create anything on a screen that we desire, using programs and software that allows us to create creatures, people, scenery, buildings, animals etc. The principle difference to other traditional animations, is that nothing has to hand drawn and authentic objects do not have to be used like in stop motion animation, because it is replaced with 3D Modelling, using virtual visuals.
It can be used variously for films, TV, commercials and now creates video games which are based upon computer modelling. In films, it beneficial for the use of visual effects because quality is higher and can be more easily controlled for aspects such as effects like an explosion, or large scale shots where more people can be added to a crowd, or more trees in a background etc; saving the use of more actors or finding the right location, because it can be easily adjusted.
CGI may have taken off into public and businesses during the late 70’s, however, was first inspired by a group of Russian mathematicians in 1968. A special program was made on a computer, able hundreds of frames for film material. Their breakthrough was a model of a moving cat; the very first virtual moving image.

This was a discovery that would lead to one of the most revolutionised developments.
A few years later, Peter folded created the first CGI animated short film, using the worlds first key frame animation software. This was an exceeding evolvement in animation and was taken great notice of by everybody as by this time many people were experimenting and creating new ways of designing techniques for movies, which were rapidly evolving as technology grew bigger in industry. Throughout the 1970s, CGI was being used in television and developing fast, until the first 3D CGI was created in 1976 by Futureworld. He used materialisation and other enhancing effects to make images look 3D. Picture was starting to become more realistic, with no pixalated look, and was clear to see.
All this famously encouraged the well known director of George Lucas. His Star Wars films were a significant success, then and now, being one of the most well known series of films, and still being continued with more films today. After seeing what CGI could offer, he used the upmost effects that he could to create an all new huge box office hit in 1977. Star Wars consisted of using actors and CGI together, including the modelling of spaceships and lightsabers; all of which had a 3D and realistic effect that matched the human actors. Alien and Superman were just two of the films that were inspired and awed by Lucas’ effects and the use of the possibilities of CGI.

Later, technology developed and so CGI had to develop alongside it. Computers were invented and becoming increasingly popular with the public. During the 1980’s CGI made a number of fundamental steps. There was a first CGI human character, the creation of alien like creatures, and new techniques such as fully rendered CGI which is seen most often in ‘TRON’. CGI was improving fast as the demand got more, and the sector became so large. It became more and more photo realistic, examples being from ‘Terminator’ and ‘Jurassic Park’ which became hugely well known in the film industry. Game consoles were also being matured due to the film industry. 3D supported gaming consoles like the Playstation were released, where the audience was able to play animated 3D games just like the films.
From all this, CGI was the most developed and the most popular as the increase in improvements arrived so fast. Come the 21st century, films were making even further possibilities. ‘Lord of the Rings’ was the first to make use of an artificial intelligence digitally created characters, and created the first photo realistic motion captured character. ‘The Matrix’ first used Universal Capture to to capture more frames, and ‘The Polar Express’ was the first to use motion capture on all its characters. Following films and games continued to push boundaries and developing the art of CGI further.
