What is CGI and who invented it? CGI or computer-generated technology is the use of special visual effects using computer software. This very clever technology uses still or animated visual content, most commonly 3D computer graphics, to create characters, scenes and special effects. Edwin Catmull and Frank Parke were the original pioneers in the field and were the first filmmakers to use this technology in the film “Westworld” in 1973. How does CGI work? This technology uses a variety of methods to achieve the desired effects. Using algorithms, a series of complex structures can be created. The two-dimensional images can then be transformed into three-dimensional vector shapes. This 3D graphics software can also be used to change simple shapes into more complex forms made from flat triangles and quadrangles. Image editors can also layer CGI into digital film footage. This is more commonly known as “compositing” and uses green screens to aid the process. How is CGI relevant to retail? For most of us, when we hear the term “CGI”, we automatically think of the special effects that are used in films such as fight scenes with dinosaurs or flying scenes on broomsticks.
