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 designed based on concept art and animated using techniques like inverse kinematics and motion capture. Motion capture helps capture realistic character movements in games like Heavy Rain and LA Noire where facial expressions are important. In films, motion capture and CGI are used, with CGI enhancing backgrounds and adding computer-generated elements. Motion capture also helps make animated films feel realistic.
