Computer-generated imagery (CGI) refers to the creation of still or animated visual content using computer software. It is widely used in various fields, including film, video games, and advertising, to produce realistic images and effects that would be difficult or impossible to achieve with traditional methods. CGI allows artists and designers to create detailed 3D models, textures, and environments. By manipulating light, color, and perspective, they can generate lifelike scenes or imaginative worlds. This technology has transformed the entertainment industry, enabling filmmakers to bring their creative visions to life with stunning visual effects.
