3D animation uses computer graphics to make 3D models perform actions. There are three main phases: modeling, animation, and rendering. It is commonly used in video games, movies, and television. In video games, 3D animation is used for characters, environments, and objects. Models are created based on concept art and then animated. Inverse kinematics helps characters connect realistically to their surroundings. Motion capture provides highly realistic character movements, as seen in games like Heavy Rain and LA Noire. In films, CGI enhances backgrounds and adds characters, while motion capture gives animation a realistic look and feel.
