ABSTRACT
In this chapter we present a method for creating a fully dynamic multilayered real-time water rendering approach. This approach can represent the volumetric properties of water and the physical formation of volumetric foam, thereby creating much higher visual fidelity than previous real-time approaches. It is based on a very fast particle-based fluid simulation that is fully hardware-accelerated using Nvidia PhysX and rendering in OpenGL, and therefore easily runs at real-time frame rates. The algorithm has a small memory footprint and is simple to implement and integrate into existing rendering engines. Additionally, our method is highly configurable from an artistic point of view, and thus can produce a multiplicity of visual appearances to help to create the desired atmosphere for a scene (see Figure 3.1).
