Practical Simulation of Surface Tension Flows
A production-tested method for incorporating surface tension effects into an existing 3D fluid solver. The method avoids the excessive time-step restriction normally associated with surface tension.

Image-Based Fluids
For "Shrek 2," image-based fluid simulation enabled more precise art direction to achieve realistic, believable fluid interaction between characters and their environments.

Leveraging Third-Party Tools for Art-Driven Fluids & Foliage
For "Shrek 2," we combined Maya technologies for foliage and fluids with PDI/DreamWorks' in-house tools to create an improved feedback loop among art directors, modelers, and the final rendered imagery.
