motion capture

Meaning

Motion capture (often abbreviated as mo-cap) is a technology where an actor's physical movements and facial expressions are recorded by digital cameras and translated into a 3D computer-generated character. This technique is widely used in CGI-heavy films, animation, and video games to make fictional creatures or digital characters move realistically.
