Fast-forward EG22 Coupling 3D Liquid Simulation with 2D Wave Propagation for Water Surface Animation

This our EG 2022 fast-forward for our paper "Coupling 3D Liquid Simulation with 2D Wave Propagation for Large Scale Water Surface Animation Using the Equivalent Sources Method" by Schreck, Wojtan Computer Graphics Forum (Eurographics 2022) pdf: https://theses.hal.science/INRIA/hal-03641349v1 Abstract: This paper proposes a method for simulating liquids in large bodies of water by coupling together a water surface wave simulator with a 3D Navier-Stokes simulator. The surface wave simulation uses the equivalent sources method (ESM) to efficiently animate large bodies of water with precisely controllable wave propagation behavior. The 3D liquid simulator animates complex non-linear fluid behaviors like splashes and breaking waves using off-the-shelf simulators using FLIP or the level set method with semi-Lagrangian advection.We combine the two approaches by using the 3D solver to animate localized non-linear behaviors, and the 2D wave solver to animate larger regions with linear surfac
