We propose a fast method of simulating large-scale liquid phenomena by coupling 2D and 3D smoothed particle hydrodynamics (SPH). Our method combines 2D SPH-based shallow water simulation with 3D SPH simulation to effectively treat complex behaviors, such as splashes and breaking waves. To achieve realistic animation, we generate 3D particles from 2D particles by categorizing these particles according to motion and position. One-way interactions between both types of particles are described by the conservation of momentum. We demonstrate the effectiveness of our approach in various graphical scenes.
