It is an image that has been taken from one format and has been converted using computer software tools that manipulate lighting and reflections to create a photorealistic image. These tools can also create exploded and multiple views and allow you to see your product in a variety of finishes and materials before you take it to production. The computer starts with a blank screen and from there builds a computer-generated images from scratch.
History
Before Evans & Sutherland, the only graphically capable computers were incredibly expensive and therefore only used by the military.
1962 is when computer graphics began with Ivan Sutherland a Ph.D student. He wrote a simple program that enabled drawing lines of light in various geometric shapes directly onto a cathode ray tube. This program, called Sketchpad, was extremely primitive but it opened the door to a brand new use of computers, graphics.
In 1964 Sutherland teamed up with Dr. David Evans. They created the world's first academic computer graphics department. It was from this computer graphics department that such things as desktop publishing, virtual reality and 3D modeling originated.
In 1969 Evans & Sutherland produced the first commercial computer graphics workstation used for computer-aided design (CAD)
In 1978 George Lucas hired Edwin Catmull from NYIT to start the Lucasfilm Computer Development Division. This division began to research the application of digital technology to filmmaking.
In 1978 computer graphics studios rapidly emerged. They all began producing computer generated graphics for television, especially flying logos for companies. It is a lot easier to produce computer graphics for the television compared to film. There are many more computer calculations required to apply computer graphics to a frame of film than to a television.
In 1982, the first motion picture with computer-generated graphics appeared. Named the "Genesis Effect", for some sixty seconds of the movie Star Trek II: The Wrath of Kahn showed a missile hitting a planet and turning that dead planet into a planet flourishing with life. This entirely computer-generated sequence was the result of the efforts of Lucasfilm's Computer Division.
In the mid 1980's showed many advances in computer technology which brought about much faster and cheap computers which meant the costs of CGI'S dropped in price which put many companies under pressure. Many companies were unable to pay loan repayments, however one company PDI managed to stay out of debt and become one of largest commercial CGI companies.

Toy Story (1994) was the first completely computer generated film.
