Under The Stairs!

It seems like you can’t claim to be in the business of next-gen technology these days until you’ve wheeled out a giant floating man-face. David Cage summoned the disembodied head of Max von Sydow to boggle over the stage at the PS4 reveal, and now, not to be out-done, Nvidia have revealed their own real-time face-o-tech at their GPU Technology Conference in California.

Aiming to help us clamber up the other side of the uncanny valley, Face Works uses a face and motion capture technology developed at the University of Southern California’s Institute of Creative Technology (ICT). The Light Stage technology is able to capture data to within a tenth of a millimetre using photographic techniques that capture the geometry of an actor’s face as well as the light transmission through human skin and the reflections that come from the oils too.

As well as the still images the Light Stage then uses video capturing to grab around thirty different facial expressions from the actor involved. Once all that information is captured it’s then compressed down to a set of meshes that can be used to recreate and animate a digitised version of that face.

Nvidia have worked with the ICT and managed to get this compressed data down from the 32GB it is in its raw form to around 400MB. At that size it is now possible to do the animation in real time and that is exactly what Jen-Hsun Huang has going on behind him on stage in the video below.

Certainly looks the part.
 
Sounds promising and put that with tressfx and could be jaw dropping visuals.

I wonder how much VRAM it consumes? Sorry Tommy only joking :p
 
For gaming use you can no doubt get that dataset down a lot smaller, you probably only need around 1/25th of the detail level it provides for convincing videogame simulation (most people probably wouldn't notice/care if it was reduced down smaller than that).

haha the teleprescencing thing was a little bit wtf. how would an infinitely more complex pc destroying simulation be better than... video conferencing. but it's bloody amazing. it's almost beyond uncanny valley, which is an amazing thing
 
Zoolander what LOL, it is a little ironic that with TressFX they chose a bald man however, looks brilliant will be cool to see this put into play in the future
 
Pretty sure the reason he is bald is because facial realism is years ahead of hair, which behaves almost like a fluid in terms of physics, also the amount of strands. It's funny considering things like micro-expressions and the oodles of muscles required just to smile, while hair just sits on your head.
 
Using those cameras to capture hair would be problematic, especially long hair which would mask skin detail. Simulating hair can be done fairly well tho the dawn bit beforehand has fairly decent hair.

If TressFX was an AMD only tech, I would have bought something like a 7850 to use for it. I love pretties and the more the better.

Replied as well bud :)

Well our missus must both be lookers then as the haters must have mingers big man.:D

Here's some more goodness for you, I know you will enjoy:


Stunning effects, absolutely stunning and what Nvidia should push more imho.

Thanks btw.;)
 
I think those effects look stunning. It is a shame it is one of those stupid "Play for free" but spend loads to get upgrades titles :(
