We propose a method for simulating the motion effect of three-dimensional water surface. First, the shape of water surface is built by the method of fractional Brownian motion. Secondly, the simplified equation of fluid mechanics is discretized by using central-differences method. Finally, the texture mapping and the LOD construction for simulation of large-scale water surface are also discussed. Experimental results show that this method is effective and it can achieve a good visualization effect.
