    Efficient large-scale hybrid fluid simulation



    State-of-the-art methods for fluid simulation, including velocity-based grid methods and smoothed particle hydrodynamics [Bridson and Müller-Fischer 2007], require a detail vs. domain size tradeoff. As a result, scenes with large spatial scales are restricted to coarse detail under the restriction of limited computational resources. The elliptic problems solved for incompressibility projection in these simulations are bandwidth-bound, since domains of interest are not cache resident on current generation hardware. As a result, limited optimization is possible, and interactive performance is not possible for medium-large scenes.
