There are two types of digital armatures: Keyframing (stop-motion) armatures and real-time (puppeteering) armatures. Keyframing armatures were initially developed to assist in animating digital characters without basing the movement on a live performance. The animator poses a device manually for each keyframe, while the character in the animation is set up with a mechanical structure equivalent to the armature. The device is connected to the animation software through a driver program and each move is recorded for a particular frame in time. Real-time armatures are similar, but they are puppeteered by one or more people and captured in real time.
