Hi guys I am trying to create a game with realistic facial animation, the problem is I am totally new to the project and haven't got a clue on how do games usually manage this issue, are there any links or material to get me started?

I was thinking on facial animation which can be managed in real-time, that is generating expressions and morph between them as well as lip-sync, as its done in games like Mass Effect (but obviously on a more humble level).

Thanks,
--Gabriel

Game engines will typically use middleware such as FaceFX for quite a large part of their facial animation needs. Basically that middleware generates animations based on a wav and a morpheme table that animators set up (which maps how morphemes affect face bones). During runtime these animations are used to skin the face skeleton. Recent versions of FaceFX support emotion tags, which allow the animators to specify how a line tagged with 'sad' influences the generated animation as opposed to, say, a line tagged as 'happy' (obviously these tags and their mapping are arbitrary).


You can also create a library of stock expressive additive animations--such as 'eyebrow raise', 'eye roll', etc. Then you can play and mix these into your face skeletons no matter what animation (if any) are being played on them.

Basically the solutions are probably what you expect, just very skillfully and artfully done.

Thanks for your reply, do you happen to know any sources of info (articles, tutorials or whatever) that explain how to actually implement it? I can't afford the use of commercial products such as FaceFX so I'll have to rely on learning myself :)

Thanks for the link, it should get me started :)

For the record, I also found this link with a survey on facial animation techniques. Hope it helps someone else.
