CGI Full Form
What is the full form of CGI ?
CGI is the abbreviation for "Computer-Generated Imagery." CGI is a computer graphics application that is used to create realistic-looking 3D pictures, animations, architectural design, special effects used in films, art used in video games, visual arts, etc. CGI is used to create images in television programmes, video games, commercial films, short dramas, stimulators, print media, etc. Computer-generated imagery is built with the help of wireframe prototypes. Using wireframe, we can give the reflection and illumination characteristics that can be changed according to the images and videos necessary to make them appear real.
Working of CGI
Initially, the computer-generated pictures are created by the artists, and then the texture, pattern, color, etc., of the graphics are adjusted to make them look real. The adjustments are done in such a way that the graphics look real, not virtual or cartoonish. In live films, the graphics are combined with previously filmed scenes. To combine graphics in this way, the lighting from the graphics must match the scenes to make the finished product seamless.
Movies that make good use of CGI
In 1973, CGI was used for the first time in Michael Crichton’s movie "WestWorld." Then, it was used in the movie "Star Wars." In 1993, it was used in the movie "Jurassic Park" to give realistic effects. Movies like Avatar, Lord of the Rings, Inception, Finding Nemo, etc., make very good use of CGI.
Different aspects of CGI
There are many different aspects to CGI, which can be divided into three categories:
Rendering: Rendering means creating an image from a model. This can be done using ray tracing, morphing, etc.
Animation: Animation refers to creating a sequence of digital images that simulate movement. This can be done using simulation, keyframe animation, etc.
Special Effects: Special effects help us to add digital effects to live scenes to make them look more realistic. This can be done using compositing, 3D projection, etc.
