What is Computer-generated Imagery (CGI)
In basic terms, Computer-generated Imagery, or CGI, refers to the utilisation of computers to create pictures or characters in film and television. It can also be defined as the process of creating and manipulating images that do not exist in the physical environment for being captured on film or video, according to MasterClass. These images can be either static or dynamic and are utilised in both 2D and 3D movies.
Due to its increased affordability compared to the past, CGI is now extensively used to generate specific elements of a shot or a scene, or even a substantial portion of an entire sequence.
Today, CGI is utilised in a wide range of films, including period/epic or sci-fi genres, to create specific elements, objects, or even entire background environments. Interestingly, even makers working on films that are outside of these genres embrace CGI technology to enhance the overall choreography of scenes or the film as a whole by incorporating intricate details.
