SUMMARY:Real-time Height-field Simulation of Sand and Water Mixtures
DESCRIPTION:Haozhe Su (Rutgers University, LightSpeed Studios); Siyu Zhang
  and Zherong Pan (LightSpeed Studios); Mridul Aanjaneya (Rutgers Universit
 y); and Xifeng Gao and Kui Wu (LightSpeed Studios)\n\nWe propose a height-
 field-based real-time simulation method for sand and water mixtures. Inspi
 red by the shallow-water assumption, our approach extends the governing eq
 uations to handle two-phase flows of sand and water using height fields. O
 ur depth-integrated governing equations can model the elastoplastic behavi
 or of sand, as well as sand-water-mixing phenomena such as friction, diffu
 sion, saturation, and momentum exchange. We further propose an operator-sp
 litting time integrator that is both GPU-friendly and stable under moderat
 e time step sizes. We have evaluated our method on a set of benchmark scen
 arios involving large bodies of heterogeneous materials, where our GPU-bas
 ed algorithm runs at real-time frame rates. Our method achieves a desirabl
 e trade-off between fidelity and performance, bringing an unprecedentedly 
 immersive experience for real-time applications.\n\nRegistration Category:
