What is motion capture?
Motion capture is a technique by which a performer’s movements can be recorded digitally, and reproduced by a CG character either in real-time or after the data has been processed (depending on how the data is sampled). This allows for more realistic and natural motion in character animation. A variation of this technique uses an armature instead of a performer, and movements are made and keyframed the same way that stop-motion animators have been doing it for many years.
