Real Time Simulation of Large Scale Water Surface Based On GPU

Real time simulation of large scale water surface is one of the hot spots in virtual reality. The reality and immersion will be enhanced greatly by photorealism and astonishing water surface in virtual reality scenes. The paper creates a model of dynamic water surface from height map and random disturbing. Texture mapping,color blend and dynamic texture are integrated into this algorithm for the reality of simulated water surface. In order to raise the render speed,the paper utilizes the powerful computation ability of GPU to complete the normal computation,reflection and refraction processes. Compared with the traditional algorithms based on CPU,the experimental results of this algorithm are more photorealistic,and the render speed is much higher,which proves that this algorithm is feasible and superior in render speed.
