A Common Gateway Interface (CGI) is a standard for web servers to interface with executable programs that are installed on a server and designed to generate web pages dynamically.
These programs are known as CGI scripts and are usually written with a scripting language, however, they can be written in any programming language.
CGI also coming refers to Computer-generated imagery, this is the application of computer graphics to create or contribute to images in art, printed media, video games, films, television programs, commercials, videos, and simulators.
What did the evolution of CGI lead to?
Visual scenes can be dynamic or static and can be two-dimensional or three dimensional.
The term ‘CGI animation’ refers to dynamic CGI rendered as a movie, this is now a common method that movies use in order to create scenes that would not be possible otherwise.
The evolution of CGI led to the emergence of virtual cinematography in the 1990s where runs of the simulated camera are not constrained by the laws of physics.
