The method employs a stochastic approach of extending pre-computed 2D simulation data into 3D animation. For the reality of a wave motion along the direction of its dominant propagation, we utilize a physically-based particle simulation. At the animation step, these simulation slices are stochastically sampled along the transverse direction in the time-slice domain. For surface reconstruction, we use a geometrical technique with a smoothing filter in order to remedy undesired 2D artifacts that result from the slice sampling. In conjunction with appropriate supplements, we apply our method to other types of water flows, indicating further interesting applications of a ripple and a whirlpool. ■ キーワード(和文5個程度、英文5個程度) Natural phenomena, Physically-based animation, Stochastic extension
