Two months ago NVIDIA showed off an impressive simulation of a human head from Face Works at GTC 2013. Now the company has made the tech demo available for public download over here.
Meet "Digital Ira". Ira represents a big leap forward in capturing and rendering human facial expression in real time, and gives us a glimpse of the realism we can look forward to in our favorite game characters.
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.
Play with this interactive demo to see Ira immersed in three different lighting environments. Adjust his skin rendering to see the effect of sub surface light transmission through his skin. And, see the realism of his facial motion as he stares you down with a myriad of lifelike expresssions.
