Performance Capture

Performance capture is a type of acting involving body sensors that track movement. Cameras at different angles record the movement in order to create a three-dimensional position of the character. The data is mapped on a digital model in 3D software, like Maya for example, so that the digital character moves like the recorded actor.

Below is a video featuring James Cameron and the performance technology used in Avatar.

"We don't have to necessarily believe that they're 100% photo real and we don't necessarily have to believe that they actually exist--but we do have to believe them as emotional creatures," Cameron says on the Avatars in the film.

I find the head rig most interesting. It's a helmet like structure that fits comfortably on the head, along with a camera that captures the facial expression and performance.
