We present an automatic water simulation method in large scale virtual environment that employed mesh based approaches.To begin with, multi-hierarchy mesh is generated using tessellation technique.Then, CUDA Concurrent Kernels technique is implemented to make Fast Fourier Transform (FFT) and Perlin noise, two ways used to compute sea height map, execute concurrently.The results of these two approaches were combined and used to generate the final sea height.Finally, the illumination effect on sea surface and foam were simulated.This method is successfully applied in VR- GIS(Virtual Reality Geographic Information System) Integrated Three-Dimensional Simulation Platform.
