Faceshift, the markerless facial capture company, demonstrated their latest tech at Siggraph using the Sven character from Autodesk's Hyperspace Madness project. We helped out with the rigging. I wrote the facial system and our awesome modelers created the facial shapes. You can check out Sven at both the 4:09 mark and the 6:30 mark. The quality achieved with Faceshifts system is pretty impressive!
