text: "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.\r\nWe 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 surface physics. We use the surface motion
from the 3D solver as boundary conditions for 2D surface wave simulator, and we
use the velocity and surface heights from the 2D surface wave simulator as boundary
conditions for the 3D fluid simulation. We also introduce a novel technique for
removing visual artifacts caused by numerical errors in 3D fluid solvers: we use
experimental data to estimate the artificial dispersion caused by the 3D solver
and we then carefully tune the wave speeds of the 2D solver to match it, effectively
eliminating any differences in wave behavior across the boundary. To the best
of our knowledge, this is the first time such a empirically driven error compensation
approach has been used to remove coupling errors from a physics simulator.\r\nOur
coupled simulation approach leverages the strengths of each simulation technique,
animating large environments with seamless transitions between 2D and 3D physics."
