Google Tech Talks
February, 29 2008
ABSTRACT
I will present recent work for acquiring,
rendering, and displaying
photoreal models of people, objects, and dynamic
performances. I will
overview 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". I
will then describe initial work with our lab's
Light Stage 6 system to
combine image-based relighting with free-viewpoint
video to capture and
render full-body performances. I will also
describe 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. I will conclude 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.
Speaker: Dr. Paul Debevec, University of Southern
California Institute for Creative Technologies
Paul Debevec is the associate director of
graphics research at USC's
Institute for Creative Technologies (USC ICT) and
a research associate
professor at USC's Department of Computer Science.
His Ph.D. thesis at UC
Berkeley presented Façade, an image-based
modeling and rendering system for
creating photoreal virtual camera motion through
architectural scenes from
photographs. Using Façade he led the creation of
a photoreal animation of
the Berkeley campus for his 1997 film "The
Campanile Movie" whose
techniques were later used to create virtual
backgrounds for the "The
Matrix"; he went on to demonstrate new image-based
lighting techniques in
his animations "Rendering with Natural Light",
"Fiat Lux", and "The
Parthenon". He also led the design of HDR Shop,
the first widely used high
dynamic range image editing program. Paul received
ACM SIGGRAPH's
Significant New Researcher Award in 2001 and
co-authored the book "High
Dynamic Range Imaging" in 2005. Most recently, he
chaired the SIGGRAPH
2007 Computer Animation Festival.

Technology preview of an early version of VRay
standalone realtime rendering. Shown at the Chaos
Group usergroup meeting at Siggraph 2007.
This was shot with a hand held Fujifilm FinePix
F30 compact still camera, so please excuse the
less than great quality.
