Ok, this seems to be doing the rounds on various news sites, so I'll post it here if anyone hasn't seen it. It looks pretty spectacular, but what they're sorta not telling you in that article is that only the facial area is computer generated. They filmed an actress, scanned her facial expressions, and plonked it straight back on her face.
Higher-res video here:
They claim it's a leap over the uncanny valley problem, but it's a sort of a cop-out solution I think, since they're basically scanning a face and rendering it again.
It reminds me, Team Bondi has some facial scanning technology that they've patented (revealed in a job news item). Would be curious to see that when L.A Noire sees its release.
