And the Oscar goes to . . .

Scientific and Technical Award (Technical Achievement Award). To Christophe Hery, Ken McGaugh and Joe Letteri for their groundbreaking implementations of practical methods for rendering skin and other translucent materials using subsurface scattering techniques. These groundbreaking techniques were used to create realistic-looking skin on digitally created characters.

Scientific and Technical Award (Scientific and Engineering Award). To Per Christensen, Michael Bunnell and Christophe Hery for the development of point-based rendering for indirect illumination and ambient occlusion. Much faster than previous ray-traced methods, this computer graphics technique has enabled color bleeding effects and realistic shadows for complex scenes in motion pictures.
