When 3D computer graphics is applied to the field of special effects, it is known as computer generated image (CGI). Nowadays, it is widely used for movies as well as for television programs, whether it is an advertisement or a television newscast. that he also found use in print media. Real-time computer graphics are most often applied to video games, but they are not called CGIs too often. However, there are video games that “cut out” scenes that are pre-rendered, as well as introductory movies that surely require the application of CGI (Computer Generated Imagery) technology.

The most widespread use of CGI is in the field of special effects, rather visual effects, because, with the use of CGI, the quality obtained is much better and better than any other process and, apart from that, visual effects are much more controllable than any process of a physical nature. Many other processes would require the hiring of extras who would play in the crowd scenes and, aside from that, the construction of miniature sets is sometimes also required. These take a lot of time and are also more expensive. Computer-generated images (CGI) are so superior to most other processes that it allows users to create or generate images of different natures that would otherwise be impossible with any other process or Technology and, apart from that, CGI also saves a lot of time and these factors contribute to the popularity of this technology.

This technology is so superior that it will not allow a single artist to produce huge amounts of content and this also in a very short time without even having to resort to actors, without expensive building sets or other accessories. Nowadays, computer-generated imaging software (CGI) is widely available in the markets. At the same time, the increased speed of computers allows a single artist, or even a small company, to produce movies and art games, all in the comfort of their homes that can compete with the Grade A material of large production houses. .
