What is the full form of CGI?
CGI full form is computer generated imagery. CGI is the use of computer graphics to generate realistic-looking (3D) images, animation and visual art, anatomic modeling, architectural design, cinema special effects, electronic media, and video game art, among other things. It is used to create or contribute to pictures in print media, art, television programs, movies, shorts, video games, commercial films, and simulators.
CGI is created with the assistance of wireframe prototypes. The wireframes can be endowed with attributes, such as reflection and illumination. Such characteristics can be altered based on the image and video requirements to make them appear authentic.

Working of CGI
- First, the artists create computer-generated graphics, and then they adjust the texture, color, and lighting to make them appear authentic.
- These modifications make the animation appear more realistic than cartoonish. In live-action films, visuals are combined with previously recorded footage.
- In this instance, the illumination on the visuals should match the lighting in the shot for a seamless final output.
- The first film to incorporate computer-generated imagery was “Westworld” by Michael Crichton, released in 1973.
- It has been utilized in “Star Wars” for many years. It was used in the 1993 film “Jurassic Park.”
- Other films, such as Lord of the Rings, Avatar, The Matrix, and many others, have utilized CGI.
Another CGI full form is the Common Gateway Interface. CGI functions as middleware between Web Servers and external databases and information sources. CGI interaction with an HTTP (HyperText Transfer Protocol) server has been essentially outlined by the World Wide Web Consortium. It is a technique that permits a web browser to submit modes over a web server and connect to services. Sending forms and connecting to applications on the web is the simplest way to use the internet.
CGI can also be defined as a set of rules/standards that permit a script or program to submit data back to the server where it is always processed. CGI applications are used to generate postings and conduct dynamic actions, particularly when someone fills out an HTML form and clicks the “submit” button. CGI applications may be written in any programming language, including PHP, Perl, and Python.
Common Gateway Interface – Characteristics
- CGI is thoroughly defined and supported.
- Scripts are typically written in C, Perl, or perhaps a basic shellcode.
- It is a technology that allows HTML to be used in the interface.
- CGI is the most efficient approach to generating a counter at this time.
Advantages of CGI
- CGI makes it much simpler to develop sophisticated functions than Java. Using a previously prepared script is frequently easier than producing one’s own.
- CGI describes how applications can be created in any language and on any platform as long as they adhere to the standard.
Constraints of CGI
- Generally, it is difficult to store information between page loads in memory.
- There is a substantial amount of existing code, much of it in Perl.
- CGI requires numerous time intervals.
