Computer generated images (CGI) are digital images that are created using specialized software and algorithms. These images can be used in a variety of contexts, including film, television, video games, and advertising. Some examples of CGI include computer-animated movies, special effects in live-action movies, and 3D models used in video games.
One of the earliest and most famous examples of CGI is the 1982 film "Tron," which used computer-generated imagery to create the world inside a computer. The film's groundbreaking visual effects helped to establish CGI as a viable tool for creating realistic and imaginative worlds in film and television.
Since then, CGI has become an integral part of the film and television industry, with many blockbuster movies relying heavily on computer-generated imagery to create their special effects. For example, the "Lord of the Rings" and "Harry Potter" franchises both used extensive CGI to create their fantastical worlds and creatures.
In addition to film and television, CGI is also used extensively in the video game industry. Video game developers use CGI to create 3D models of characters, environments, and objects, which are then rendered in real-time as the player moves through the game world. This allows for a level of realism and detail that would be impossible to achieve with traditional hand-drawn animation.
CGI is also used in the advertising industry to create digital graphics and animations for use in commercials, billboards, and other promotional materials. This can include everything from simple 2D graphics to complex 3D models and animations.
Overall, CGI has revolutionized the way that visual media is created, allowing for more realistic and imaginative worlds to be brought to life on screen. As technology continues to advance, it is likely that CGI will continue to play a major role in the film, television, video game, and advertising industries.
