Motion capture, motion tracking, or mocap are terms used to describe the process of recording movement and translating that movement onto a digital model. Initially invented in Scotland, it is used in military, entertainment, sports, and medical applications.

Motion capture, motion tracking, or mocap are terms used to describe the process of recording movement and translating that movement onto a digital model. Initially invented in Scotland, it is used in military, entertainment, sports, and medical applications. In filmmaking it refers to recording actions of human actors, and using that information to animate digital character models in 3D animation. When it includes face, fingers and captures subtle expressions, it is often referred to as performance capture.
In motion capture sessions, movements of one or more actors are sampled many times per second, although with most techniques (recent developments from ILM use images for 2D motion capture and project into 3D) motion capture records only the movements of the actor, not his/her visual appearance. This animation data is mapped to a 3D model so that the model performs the same actions as the actor. This is comparable to the older technique of rotoscope where the visual appearance of...
