The simulation of the sea water is very important not only for the computer graphics areas,but also for hydraulic,fluid mechanics,wave dynamics and oceanography.In the paper,statistical models are used,in combination with experimental observations.In the statistical models,the wave height is considered a variable of horizontal position and time.Statistical models are based on the ability to decompose the wave height field as a sum of sine and cosine waves.Computationally,the decomposition uses Fast Fourier Transforms(FFTs),which are a rapid method of evaluating the sums.In order to improve the rendering performance,it has considered the reflection,refracion effects to the sea water color and has realized them by Texture Mapping Techniques.It has used Cg language in the OpenGL platform to fully utilize GPU.The experiments have proved that the methods have accelerated the rendering speed and made the scene more and effective.
