Motion capture (
Mo-cap for short) is the process of recording the
movement of objects or people. It is used in
military,
entertainment,
sports, medical applications, and for validation of computer vision and robotics. 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. When it includes face and fingers or captures subtle expressions, it is often referred to as
performance capture. In many fields, motion capture is sometimes called
motion tracking, but in filmmaking and games, motion tracking usually refers more to
match moving.
