Jonathan Cohen is a research scientist with NVIDIA, where he focuses on physical simulation and parallel software architecture. Prior to joining NVIDIA, he held technology R&D positions in the feature film visual effects industry. His work can be seen on films such as Spider-Man 3, The Chonicles of Narnia: The Lion, the Witch, and the Warddrobe, The Cat in the Hat, and the upcoming John Hancock. In 2007, he was awarded an Academy Award for Technical Achievement for his work on fluid simulation and volumetric modeling. He has held positions with Sony Pictures Entertainment, Rhythm and Hues Studios, The University of Southern California, and Microsoft. He received a Bachelors of Science from Brown University.

In this talk, I will discuss how Sony Imagework's visual effects team tackled several of the technical and artistic challenges of Spider-Man 3. I will present details of the “Sandstorm” effects system, including how we modeled, animated, simulated, and rendered hundreds of millions of sand grains per frame at feature film quality to create the “Sandman” character. "Sandman" is a good example of a trend away from simple computationally efficient models, and towards increasing geometric complexity. I will conclude some suggestions for how to capture this trend build by building high-throughput software.
