Expression is an animation system based on an anatomical model of the face.
Using basic muscle simulations instead of morph targets, Expression simplifies the creation of lifelike characters, allowing a face to be set up in a matter of hours instead of days. Expression is being released under both the QPL and a commercial license. See the licensing page for more info. Expression originated at Altiverse Systems, a company that was working on large scale persistent worlds that unfortunately ceased operations recently due to financial reasons.
