Weta’s specialty is motion capture, which relies on sophisticated software and hardware to transfer an actor’s body movements and facial expressions to an animated character. The actor wears a black suit with light-colored dots; to detect his movement, optical systems track those dots.
For Avatar, Weta pushed the state of the art. First, it employed head-mounted cameras, worn by the actors, that tracked dots on their faces. The use of the camera greatly increased the range of emotions that could be transferred to the faces of the animated characters, enabling audiences to relate more closely to the computer-generated creatures.
Second, the Weta system enabled director James Cameron to see the results of motion capture essentially in real time. As the actors performed, Cameron was able to look at a screen near his camera and see, in place of actors in black suits, a slightly cruder version of the blue computer-generated space aliens that audiences would see.
