And the Oscar goes to . . .

Scientific and Technical Award (Technical Achievement Award). To Kelly Ward Hammel, Aleka McAdams, Toby Jones, Maryann Simmons and Andy Milne for the Walt Disney Animation Studios Hair Simulation System. The WDAS Hair Simulation System is a robust, predictable, fast and highly art-directable system built on the mathematics of discrete elastic rods. This has provided Disney artists the flexibility to manipulate hair in hyper-realistic ways to create the strong silhouettes required for character animation and has enabled a wide range of complex hairstyles in animated feature films.
