what is a cgi

CGI stands for Computer-generated imagery, which is a specific technology or application of computer graphics for creating or improving images in art, printed media, simulators, videos, and video games. CGI can refer to both 2D and 3D computer graphics, with the purpose of designing characters, virtual worlds, or scenes and special effects in films, television programs, commercials, etc. . The creation of CGI involves a very long process that is challenging and very technical, and teams are large and diverse, involving people ranging from hardcore coders to illustrators and non-artists. Some of the most creative and technical functions involved in the creation of CGI include algorithms, 2D pixel-based image editors, 3D graphics software, ray tracing, and shader programming routines. CGI is used to produce images for many purposes, including visual art, advertising, anatomical modeling, architectural design, engineering, television shows, video game art, and film special effects, as well as augmented reality (AR) and virtual reality (VR) applications.
