And the Oscar goes to . . .

Scientific and Technical Award (Technical Achievement Award). To Steve LaVietes, Brian Hall and Jeremy Selan for the creation of the Katana computer graphics scene management and lighting software at Sony Pictures Imageworks. Katana’s unique design, featuring a deferred evaluation procedural node–graph, provides a highly efficient lighting and rendering workflow. It allows artists to non–destructively edit scenes too complex to fit into computer memory, at scales ranging from a single object up to an entire detailed city.
