Abstract:
We present a production-proven method for up-resing volumetric fluid simulations, allowing creation of high-resolution results efficiently from fast-to-compute, low resolution sims. Existing approaches often rely on secondary simulation and supplementary turbulence to inject missing details at higher resolutions. At Industrial Light and Magic (ILM), we have devised a simpler approach, one that is frame independent and therefore parallelisable across frames. Our combination of gridless advection, anti-aliased sampling and camera-frustum aligned grids has been used with great success on many recent productions and is a mainstay of our fluids toolkit.
