SUMMARY:A Monte Carlo Method for Fluid Simulation
DESCRIPTION:Technical Papers\n\nA Monte Carlo Method for Fluid Simulation\
 n\nRioux-Lavoie, Sugimoto, Özdemir, Shimada, Batty...\n\nWe present a nove
 l Monte Carlo-based fluid simulation approach capable of pointwise and sto
 chastic estimation of fluid motion. Drawing on the Feynman-Kac representat
 ion of the vorticity transport equation, we propose a recursive Monte Carl
 o estimator of the Biot-Savart law and extend it with a stream function fo
 rmulation that allows us to treat free-slip boundary conditions using a Wa
 lk-on-Spheres algorithm. Inspired by the Monte Carlo literature in renderi
 ng, we design and compare variance reduction schemes suited to a fluid sim
 ulation context for the first time, show its applicability to complex boun
 dary settings, and detail a simple and practical implementation with tempo
 ral grid caching. We validate the correctness of our approach via quantita
 tive and qualitative evaluations -- across a range of settings and domain 
 geometries -- and thoroughly explore its parameters' design space. Finally
 , we provide an in-depth discussion of several axes of future work buildin
 g on this new numerical simulation modality.\n\nRegistration Category: FUL
