When NVIDIA released the GeForce GTX Titan video card they debuted a lifelike human face rendering demo called FaceWorks. NVIDIA has made that demo available to download and you can grab the 309MB file here. The character in the demo is called “Digital Ira” and in the demo you can see him immersed in three different lighting environments. You can also adjust his skin rendering to see the effect of sub surface light transmission through his skin. If you are ready to see some awesome realism when it comes to facial expressions be sure to give this demo a test drive.
This demonstration highlights the state of the art in performance capture. All Ira”s motions were acted out in a “light stage” at the Institute for Creative Technology at USC. The team there headed by Dr. Paul Debevec is able to photographically capture facial geometry, surface detail, and lighting information of an actor without any of the traditional tricks of face markers or special makeup. This light stage data is pulled into NVIDIA”s demo engine, and using FaceWorks rendering technology we witness a realism of human facial rendering never before seen in real time. FaceWorks shading gives Ira lifelike skin, eyes, lips and teeth. Adaptive tessellation keeps the curves of his face perfectly smooth.
