Abstract:
This paper presents a real-time water simulation framework with respect to wave propagation in flowing liquids. The presented method is based on the coupling of liquid flow simulation and simulation of surface waves. Physically, our system combines the solution of the Navier-Stokes Equations with the solution of the 2D Wave Equation. Numerically, we combine the concept of wave particles with a FDM-based flow simulation. Thus, wave propagation in fast flowing liquids (e.g., a creek) can be simulated in real-time. Therefore, it is very suitable for today's video games and VR-environments. Finally, we discuss the coupling of the liquid simulation with a rigid-body simulation and a fountain simulation.
