Motion Capture is a method of bringing computer generated people and objects to life, using human motion and actions.
This exciting new technology gives realistic movement to computer generated characters.
Here's how the producers did it. Light sensors were attached to martial artists. These sensors were placed at every joint, and point of rotation on the fighter's bodies. Any movement by the martial artists were then captured by four cameras, positioned in each corner of a room, so when the fighters are, for example, flipping over one another, these cameras pick up all of these exact moves. Once the movements, or the "Motion Data" is captured you then go back to your computer system. The motion data is first attached to a stick figure model. It is later incorporated into the three dimensional characters, in the computer. Once this process is complete the skins and texture are added to produce a completely realistic moving 3D Character.
It's an amazing process that is revolutionizing animation history.
