  • The breakthrough of CGI was with the first CGI movie to use 2D trickery, Vertigo, from 1958
  • In 1972, 3D CGI effects and graphics were used for the first time to make the short movie “A Computer Animated Hand”
  • In the 90s, CGI technology made a huge boom and it started to be used in the legendary movies of the decade: Therminator II, Star Wars, The Matrix and many more

  • The first video games that used 3D technology are: Battlezone (1980), Maze (1981) and the beginnings of console 3D games were with Virtua Fighter (1993) and Super Mario 64 (1996)

As the CGI animation software got better and better throughout the years, we got remarkable movie pieces thanks to the CGI visualization. Some of them include:

  • Ghostbusters (1984)

How Does it Work?

Before using the CGI effects the movie designers start with making the graphics of the movie. While using the CGI animation software it’s important to pay attention to the texture and lighting to make the visual content real. 

The process of generating images with CGI can be done with algorithms and creating fractals that lead to complex visual patterns. There is also a possibility to make vector shapes 2D pixelated images and design visual patterns.

The 3D CGI is produced by using ray tracing or bitmap graphics. With the use of the CGI effects that can be created by combining CGI into the film in layers. This technology is mostly used when a simulated background is added to the well known green screen.

The CGI animation software has the power to animate anything that can be imagined by the human brain.

What are CGI influencers?
