What does the acronym CGI stand for?

According to Science Daily, Techopedia, and Tech Target, CGI stands for computer-generated imagery. This is the application of computer graphics – specifically, 3D computer graphics but sometimes 2D – to special effects in films, television programs, and commercials. Video games also use real-time computer graphics as well as pre-rendered cut scenes and intro movies that are also CGI. CGI is also used for visual effects. Using CGI for these effects is usually both higher quality, more controllable, and cheaper than doing physical effects like hiring extras for crowd scenes or constructing miniatures for effects shots. They only need one artist and software rather than thousands of actors, expensive set pieces, or props. CGI ws famously used in Jurassic Park. Nowadays, you see CGI in a plethora of different films – even ones you didn’t think you would. It can be sued for touching up an actor’s face, aging them for a flashback or flashforward, and a plethora of other things. 

CGI can also be used to build a library of props, wireframe models that have properties like reflection and illumination, and images and effects which may not be feasible using other methods. It is also a safe way to carry out complex effects. CGI artists can edit a single frame of media one by one for lifelike visual effects and create complex visualization. This creation of images can also be called VFX. CGI is one of the most cost effective methods for developing videos for electronic media like movies and video games. CGI is extremely versatile and can be used in many different ways to create groundbreaking visual effects for film, TV, video games, and more. 

CGI technology has also been used to replace stop motion animation. Disney and Pixar are famous for making CGI animation. The first film to use computer animation was Toy Story, released in November 1995. Almost every June, they release a new CGI film. 3D animations can also be used for virtual reality films or experiences. Below is a list of Pixar films from Radio Times.
