Let have a quick look about Computer-Generated Imagery (CGI)

Computer-generated imagery (also known as CGI) is the application of the field of computer graphics or, more specifically, 3D computer graphics to special effects in films, television programs, commercials, simulators and simulation generally, and printed media. It is an image that has been taken from one format such as a CAD (Computer-Aided Design) file and converted using computer software tools that manipulate lighting and reflections to create a photo realistic image. CGI images can be combined with other images. This is a great advantage for manufacturers and inventors of products.

CGI started with 2D and now is 3D. 2D CGI was first used in movies in 1973's and in the early 2000’s; computer-generated imagery became the dominant form of special effects. The software used to create computer-generated images is complicated and expensive.

Developments in CGI technologies are reported each year at SIGGRAPH (Special Interest Group on GRAPHics and Interactive Techniques), an annual conference on computer graphics and interactive techniques, attended each year by tens of thousands of computer professionals.

Some of famous CGI Film Studios in the world:
