Water Animation Using Coupled SPH and Wave Equation

This project addresses the need for interactive, real-time water animation techniques that can reproduce convincing effects such as splashes and breaking waves while being computationally inexpensive. Our method couples smoothed-particle hydrodynamics (SPH) and a wave equation solver in a one-way manner to animate the behavior of water in real-time, leveraging compute shaders for interactive performance. In this paper, we present a review of related literature on realtime simulation and animation of fluids, describe our hybrid algorithm, and present a comparison of images and computational costs between SPH, wave equation solution, and our coupled approach. Our approach is faster than a pure SPH solution, but requires fewer particles to achieve a similar appearance. In this work, however, we do not address the problem of water rendering.
