  II. CGI

  Computer-generated imagery (CGI) has come a long way since its early days in the 1960s. In the beginning, CGI was used for simple tasks such as creating wireframe models of objects. However, over the years, CGI has become increasingly sophisticated, and it is now used to create photorealistic images and animation.

  One of the earliest uses of CGI was in the 1968 film 2001: A Space Odyssey. In this film, CGI was used to create the iconic HAL 9000 computer.

  In the 1970s, CGI began to be used more widely in films, such as Star Wars (1977) and Close Encounters of the Third Kind (1977). These films helped to popularize CGI and showed the world what was possible with this new technology.

  In the 1980s, CGI continued to evolve, and it was used in more and more films. Some of the most notable CGI films from this decade include Tron (1982), The Last Starfighter (1984), and Who Framed Roger Rabbit (1988).

  In the 1990s, CGI reached new heights of realism and sophistication. Some of the most iconic CGI films from this decade include Jurassic Park (1993), Terminator 2: Judgment Day (1991), and The Matrix (1999).

  In the 2000s, CGI continued to be used in more and more films, and it became the standard for creating realistic visual effects. Some of the most notable CGI films from this decade include The Lord of the Rings trilogy (2001-2003), The Incredibles (2004), and Avatar (2009).

  In the 2010s, CGI has continued to evolve, and it is now used in a wide variety of films, television shows, and other media. Some of the most notable CGI films from this decade include Gravity (2013), Mad Max: Fury Road (2015), and The Lion King (2019).

  CGI has come a long way since its early days, and it is now an essential part of the filmmaking process. It is used to create realistic visual effects that would be impossible to achieve with traditional filmmaking techniques. CGI has also made it possible to create new and exciting worlds that would not be possible without it.

  III. Types of CGI

  There are many different types of CGI, each with its own unique set of features and applications. Some of the most common types of CGI include:

  • 2D CGI: This type of CGI is created using two-dimensional graphics, and is often used for creating animated cartoons, video games, and other types of digital art.
  • 3D CGI: This type of CGI is created using three-dimensional graphics, and is often used for creating realistic images of people, animals, and objects.
