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 (Technical Achievement Award). To Hayden Landis, Ken McGaugh and Hilmar Koch for advancing the technique of ambient occlusion rendering. Ambient occlusion has enabled a new level of realism in synthesized imagery and has become a standard tool for computer graphics lighting in motion pictures.
