CGI and "unimaginable" effects in movies

In fact, CGI is a technology that has been used a lot in the film , advertising and even printing industries. CGI is a commonly used tool because of its usability. Suppose, in a scene, the crew could hire thousands of people to do it, through CGI they could create this scene without losing so much cost.

Completely made with computers and specialized software, CGI technology will replace most dangerous scenes or create difficult to simulate characters in reality.

CGI is also said to be more robust in creating content than any other method . CGI technology was first used in movies in Westworld (1973). However, in this work CGI only shows two-dimensional content. Two of the first major films invested in CGI technology were Tron (1982) and The Last Starfighter (1984).

Until now, CGI technology has been appearing in many famous movies when people cannot play all the characters that appear in it. The most typical is the Transformer movie when all the robots inside this movie are built using the technique and not built up a complete pattern like in reality.
