What is the full form of CGI?
1) The full form of CGI is the Common Gateway Interface. CGI serves as Middleware among WWW Servers & external databases and sources of information. The World Wide Web Consortium has defined basically how a device interacts with an HTTP (HyperText Transfer Protocol) server using the CGI. It is a technology that allows a web browser to submit modes across a web server and also to hook up with systems. Sending forms and linking up with programs on the web is the easiest way for an internet web.
CGI can also be defined as a collection of guidelines/standards that allow a script or program to transmit information back to the server in which it is always processed. Especially when someone fills out an HTML form and clicks on the submit button, CGI programs are used to produce posts as well as perform some action dynamically. CGI apps may be written in any programming language, some of which could be PHP, Perl, & Python.
Characteristics of Common Gateway Interface
- CGI is well described and supported.
- Scripts are usually described in either C, Perl or perhaps even a simple shellcode.
- It is a technique that enables HTML to the interface.
- CGI is the best way to create a counter because it is presently the fastest.
Benefits of CGI
- The advanced functions are much easier to implement in CGI compared to Java. Using the script previously written is often easier than writing your own.
- CGI explains the programs are written in any language & on any platform, as long as it complies to the standard.
Limitations of CGI
- Generally, information among page loads can’t be so easily stored in memory.
- There’s a large existing code base, a bunch of it in Perl.
- CGI requires lots of intervals of time.
2) Another full form of CGI is Computer-generated imagery. CGI is the app of computer graphics to create realistic-looking (3D) pictures, animation & visual art, anatomic modelling, architectural design, film special effects, electronic media and video game art etc. It is used in print media, art, television programmes, videos, shorts, video games, commercials films & simulators to create or contribute images.
With the assistance of wireframe prototypes, CGI is built. The wireframes can be given characteristics, including reflection, illumination. Such features can be changed according to the image necessity, and videos to make them appear genuine.
Working of CGI
- First, the artists produce computer-generated graphics & then change the texture, colour and lighting to make graphics look genuine.
- Those changes make the animation look natural rather than a cartoon. In live-action movies, the graphics are blended with the shots that were previously recorded.
- In this scenario, to make the final product seamless, the illumination on the visuals should fit the lighting from the shot.
- The CGI is being used for the first time in a film in 1973; “Westworld” by Michael Crichton.
- It has been used in the film “Star Wars” after several years. It was used in the movie “Jurassic Park” in 1993.
- Other films used CGI too, such as Lord of the Rings, Avatar, Finding Nemo, Inception, The Matrix and much more.
