Natural phenomena simulation has attracted a spurt of research attention and interest in both computer graphics and virtual reality technology domains. Water is one of the most common phenomena in real world. Acquisition and modeling of different water movements have become one of the important research topics in recent years. In this paper, we design an acquisition system for capturing dynamic water surface. We also present an image-based method for water surface reconstruction. The goal of water surface reconstruction is to compute 3D coordinates and normals of dynamic water surface.
