    Nvidia demonstrates potentially revolutionary new face-rendering tech

    Graphics behemoth Nvidia has unveiled new face-rendering technology that could revolutionise characters' facial performances in video games, CEO Jen-Hsun Huang declared.

    The technology is called Face Works. What it does is condense previously massive amounts of motion-captured performance data into a size small enough that Nvidia's new £800 Titan graphics card can recall it in real-time. (Check out Digital Foundry's Titan review if you haven't already - the card's a beast.)

    That motion-captured performance data comes from 156 cameras, arranged around a spherical space, capturing 30 expressions of a person. The smallest the compiled code of these expressions could get previously was 32GB - more than a Blu-ray's worth (25GB). It was far too big to hope to recreate in real-time.

    Face Works squashes that to around 300MB. And hey presto, that motion-captured performance can be recalled in real-time.

    Huang demonstrated Face Works in video at Nvidia's GPU Technology Conference this week.

    "This is digital Ira," he said. "Ira is not a recording; Ira is being processed in real-time on a GPU called the Titan."

    Skip to 8.30 to meet him.



    Ira's performance is incredibly exciting. But what does this mean for PC, PlayStation 4 and next Xbox gaming - the obvious implication of all this?

    Huang said rendering Ira took around 2 teraflops (2 trillion floating-point operations per second). Nvidia's Titan can handle 4.5 teraflops, but PS4 can only handle 1.84 teraflops and the next Xbox 1.2 teraflops.

    As it stands, it's out of reach - but that's running at 60 frames per second in 1080p. At 30 frames per second, the calculations required are halved. With a bit of efficiency-tinkering, it's possible.

    Mind you, that's only rendering a face.

    Nvidia isn't the only company showing of some dazzling face-rendering tech. Quantic Dream, maker of Heavy Rain and Beyond: Two Souls, showed an old man's head at the PlayStation 4 reveal last month.



    And, more recently, rumours swirled around a Joakim Mogren interview on GameTrailers TV. There was speculation that Mogren wasn't real but a CGI creation made by Hideo Kojima's new Fox Engine. This could be a ludicrous theory, as many of you below have told me. All will apparently be revealed at GDC next week.

    Meanwhile, Nvidia's rival graphics maker AMD is doing next-gen hair simulation.

Vincent Sobieski, who goes by the stage name "Vincentgbr", was born in Bulgaria and raised in Great Britain. Vincent grew up with a lot of passion in music which gave him the determination to start his DJ course at Point Blank London at the age of 21. He received training from Ben Bristow, at which he succeeded in the course and obtained his DJ certificate.

After gaining 6 years DJ experience, "Vincent" recently got involved with TribalDanceFR and is a weekly resident DJ for them at Club ORBILUX.

"Vincent" has also received offers to play in various Clubs in France, these include Le Balajo, La Java, La Palace, Les Etoiles, etc.

At the beginning of 2009, he started to pursue his interest in producing music. In collaboration with professional producer and friend (Sam Hunwicke), he made his 1st track called (…) and shortly after, 2nd track "DJs The Beat".
He is also looking forward to making his own album in 2012, which promises to be really interesting. He is almost certainly going to be very busy for the future....
