Definition

CGI, or Computer-Generated Imagery, refers to the creation of still or animated visual content using computer software. This technology is widely used in various media, including films and documentaries, to produce realistic images and effects that would be difficult or impossible to capture in real life. CGI enhances storytelling by allowing filmmakers to visualize concepts, environments, and characters that might otherwise only exist in the imagination.
