Step-by-step explanation:
The first full-length feature film that was completely computer-generated was Toy Story, released in 1995. This milestone in film history represented the maturation of CGI (Computer Generated Imagery) and set a new standard for animated films. At that time, the film industry was experiencing significant technological advances, with CGI becoming an essential tool in filmmaking. The emergence of this technology made it possible to create films more efficiently and with visuals that were previously difficult or impossible to achieve. The impact of such technological advances can also be seen in other genres, such as action and science fiction films, where digital effects have elevated the viewing experience.
