anycode for facial expression simulation??

No.


No one's going to freely distrubute 'code' that will generate facial expressions.
The closest thing you *might* find is a licensed library or api for a facial expression package.
I don't know any names off the top of my head, but plan on spending $$$.

I remember seeing a old demo in ATI developer site, that simulated facial expressions, you can probably find it if you dig enough. I think it used precanned animations, tough.

thank you guys for all the replys. corman you sent a really nice link. ok now another request ...... i was hoping to find any implementations or demos on Wrinkle Simulation due to aging effect of the human face. i have found papers but no demos or distributions. so help again!!!!!!!!!

as far as wrinkle simulations, i think you're better off doing something like that yourself. The easiest way to do it is to have your artist make a young/smooth texture and an old/wrinkled texture, and interpolate between the two (and bumpmap it).

Can you throw up some links to the wrinkle papers you've found? All I found was a chapter from GPU Gems detailing skin with subsurface scattering and occlusion querying.

Firstly, try Facegen, it's only a demo, but try it out.

There's an option to export each phoneme as a .3ds file. (around 29 of them IIRC).

I did a demo ages ago where I used each of these phoneme meshes as a morph target, and lerp'ed between them to get a prestty smooth lip sync going on.

I believe Valve uses something similar in HL2.

developing something like Facegen is impossible for me at this stage. i would prefer something simpler.searching with "simulating aging effect on face images" retured a lot of papers. i really don't have the time building from scratch. so if any of you know where to get some source then plzzzz tell me. thanks........

I will tell you with impunity that that is never an answer. Using other people's source will work to an end, but if you're really interested in the field (as an artist) then you have to get it at it from scratch.

That being said, I've already told you about a full-fledged 3D face that can mouth any syllable you want that you could be playing with right now...

Dude this stuff is not easy. It's a lot of work.
