And the Oscar goes to . . .

Scientific and Technical Award (Technical Achievement Award). To Ed Catmull for the original concept, and Tony DeRose and Jos Stam for their scientific and practical implementation of subdivision surfaces as a modeling technique in motion picture production. Subdivision surfaces have become a preferred modeling primitive for many types of motion picture computer graphics.

Scientific and Technical Award (Scientific and Engineering Award). To Duncan Brinsmead, Jos Stam, Julia Pakalns and Martin Werner for the design and implementation of the Maya Fluid Effects system. This system is used to create simulations of gaseous phenomena integrated into the widely available Maya tool suite, using an unconditionally stable semi-Lagrangian solver.

Scientific and Technical Award (Scientific and Engineering Award). To Ed Catmull for the original concept, and to Tony DeRose and Jos Stam for their pioneering advancement of the underlying science of subdivision surfaces as 3D geometric modeling primitives. Their creation of essential geometric operations and sustained research on the fundamental mathematics of subdivision surfaces helped transform the way digital artists represent 3D geometry throughout the motion picture industry.
