FaceFX
Encyclopedia : F : FA : FAC : FaceFX
FaceFX is a Facial animation program developed by OC3 Entertainment. It was designed to create realistic Lip synchronization from audio files in computer games.
Face Graph
The central component of the program is the face graph. It combines bone poses and morph targets to a single target which is driven by animation curves. These are created by a speech recognition system but can also be manually edited. The facial animation is then outputted to the game engine either as bone transformation or morph target frame by frame.
Audio Analysis
To create a realistic animation curve, the program recognizes 42 phonemes and tries to take co-articulation rules into account. It also tries to create head movement, blinks, and eyebrow raises from emphasis points in the audio file.
Games using FaceFX
Probably most spectacular is the fact that Epic Games has licensed the FaceFX technology and wants to use it for the Unreal 3 Engine which means that it will be used in the upcoming titles Gears of War and Unreal Tournament 2007.
