A computer processes the data and displays the movements of the actor, providing the desired camera positions in terms of objects in the set. This allows the computer-generated characters, images and sets to have the same perspective as the video images from the camera. At the same time, the motion capture system can capture the camera and props as well as the actor's performance. This process may be contrasted with the older technique of rotoscoping.Ĭamera movements can also be motion captured so that a virtual camera in the scene will pan, tilt or dolly around the stage driven by a camera operator while the actor is performing. This animation data is mapped to a 3D model so that the model performs the same actions as the actor. Whereas early techniques used images from multiple cameras to calculate 3D positions, often the purpose of motion capture is to record only the movements of the actor, not their visual appearance. In motion capture sessions, movements of one or more actors are sampled many times per second. Raw data from Husky Sense motion capture clothing (with IMU sensors) on top of a real-time recorded moves In many fields, motion capture is sometimes called motion tracking, but in filmmaking and games, motion tracking usually refers more to match moving. When it includes face and fingers or captures subtle expressions, it is often referred to as performance capture. In filmmaking and video game development, it refers to recording actions of human actors and using that information to animate digital character models in 2D or 3D computer animation. It is used in military, entertainment, sports, medical applications, and for validation of computer vision and robots. Motion capture (sometimes referred as mo-cap or mocap, for short) is the process of recording the movement of objects or people.
