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 create both static (still images) and dynamic (moving images) images, and it refers 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. .

CGI is created using different methods such as algorithms, 2D pixel-based image editors, and 3D graphics software. 3D software can simulate the way light reacts to a surface and creates particle effects. 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.

CGI is used in many fields, 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.
