Activision recently showed off its Next-Generation Character Rendering technology, which is a new method for rendering realistic and high-quality 3D faces. The technology has been in the works for some time now, and is now at a point where faces are extremely detailed down to pores, freckles, wrinkles, and eye lashes.
In addition to Lauren, Activision also showed off its own take on the face used in NVIDIA's Ira FaceWorks tech demo. Except instead of the NVIDIA rendering, the face was done using Activision's own Next-Generation Character Rendering technology. A method that is allegedly more efficient and "completely different" than the one used for Ira. In a video showing off the technology (embedded below), the Activision method produces some impressive 3D renders in real time, but when talking appear to be a bit creepy-looking and unnatural. Perhaps Activision and NVIDIA should find a way to combine the emotional improvements of Ira with the graphical prowess of NGCR (and while we are making a wish list, I might as well add TressFX support... heh).
The high resolution faces are not quite ready for the next Call of Duty, but the research team has managed to get models to render at 180 FPS on a PC running a single GTX 680 graphics card. That is not enough to implement the technology in a game, where there are multiple models, the environment, physics, AI, and all manner of other calculations to deal with and present at acceptable frame rates, but it is nice to see this kind of future-looking work being done now. Perhaps in a few graphics card generations the hardware will catch up to the face rendering technology that Activision (and others) are working on, which will be rather satisfying to see. It is amazing how far the graphics world has come since I got into PC gaming with Wolfenstein 3D, to say the least!
The team behind Activision's Next-Generation Character Rendering technology includes:
|Javier Von Der Pahlen||Director of Research and Development|
|Etienne Donvoye||Technical Director|
|Bernardo Antoniazzi||Technical Art Director|
|Zbyněk Kysela||Modeler and Texture Artist|
|Mike Eheler||Programming and Support|
|Jorge Jimenez||Real-Time Graphics Research and Development|
Jorge Jimenez has posted several more screenshots of the GDC tech demo on his blog that are worth checking out if you are interested in the new rendering tech.
