ABSTRACT
The single largest innovation in game animation has been the widespread adoption of motion-capture—the process of capturing motion from lives actors. There are several alternative motion-capture methods, the traditional and most commonly used is via the triangulation of optical markers on a performer's suit, captured by arrays of cameras arranged around a stage so that they create a “volume” within which the performance can be recorded. Accelerometer mocap is useful for lower-budget projects or previz before real captures for larger ones. An experimental approach is to use depth-sensing cameras with no markers, applying body motion only to a physical model. The most proven way of having an efficient mocap shoot while obtaining the highest quality of acting is rehearsing beforehand. Props are an essential part of any game mocap shoot, usually taking the form of weapons or other gameplay-related items.
