This allows many tests to be done with different styles or deliveries, giving a different personality only limited by the talent of the actor. The amount of work does not vary with the complexity or length of the performance to the same degree as when using traditional techniques.The Hand Over technique is an example of this. In entertainment applications this can reduce the costs of keyframe-based animation. Low latency, close to real time, results can be obtained.Motion capture offers several advantages over traditional computer animation of a 3D model: ( February 2014) ( Learn how and when to remove this template message) Unsourced material may be challenged and removed.

It involved 'cloning' the body and face of french comedian Richard Bohringer, and then animating it with still-nascent motion-capture tools. The first virtual actor animated by motion-capture was produced in 1993 by Didier Pourcel and his team at Gribouille. Retroactively obtaining camera movement data from the captured footage is known as match moving or camera tracking. 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.Д¬amera 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. 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 2-D or 3-D 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. Two repetitions of a walking sequence recorded using a motion-capture system
