Introduction

Physically based fluid flow simulation is commonplace in many prediction and scientific computation problems. It also greatly improves the visual fidelity in computer graphics applications. However, an accurate simulation is computationally expensive. In this chapter, we present a physically plausible yet fast fluid flow simulation approach based on the Lattice Boltzmann Method (LBM) (Chen and Doolean 1998). Figure 47-1 shows the results of fluid simulation around different obstacles. In Figure 47-1a, the obstacle is a static vase, while in Figure 47-1b ...
