Facial Animation Rig for Delgo

I am Warren Grubb, Animation Director for Fathom Studios on the film Delgo. (click here for the trailer) When we R&D for the feature film Delgo, I was Technical Director and I knew we would need a facial rig for our characters that was more powerful and flexible than standard multi-targeted blendshape rigs. The solution we came up with, to describe it very simply, uses NURBS curves as influence objects on a poly mesh that is bound to control joints using smooth skining. We retained the ability to create blendshapes if necessary, but we gained, among other things, the ability for animators to create very subtle or extreme changes in expressiveness without having to send the character to a modeler for new target shapes. In most cases, this process is simple and fast enough that you can rig a head in a single day.
