Paul Debevec: “New Techniques for Acquiring, Rendering, and Displaying Human Performances”

April 16, 2008 | Saarbrücken, Germany

Speaker: Paul Debevec
Host: Max Planck Institute for Information, Computer Graphics Group

This talk presents recent work for acquiring, rendering, and displaying photoreal models of people, objects, and dynamic performances. It overviews image-based lighting techniques for photorealistic compositing and reflectance acquisition techniques which have been used to create realistic digital actors in films such as “Spider Man 2” and “Superman Returns”. It also describes initial work with the ICT Graphics Lab’s Light Stage 6 system to combine image-based relighting with free-viewpoint video to capture and render full-body performances. It will also cover a new 3D face scanning process that captures high-resolution skin detail by estimating surface orientation from the skin’s reflection of polarized spherical gradient illumination. The talk concludes by describing a new 3D display that leverages 5,000 frames per second video projection to show autostereoscopic, interactive 3D imagery to any number of viewers simultaneously.
