Water Surface Modeling

This work addresses problems of simulating ocean surface using a spectral approach by J. Tessendorf. The surface itself is generated utilizing the Fast Fourier Transform. We will see how an FFT algorithm can be implemented on graphics processor using its power in terms of parallel computations. A produced patch of surface will be tiled to simulate a large area of ocean and illuminated using classical Fresnel reflection/refraction model. Finally, the results will be compared depending on different input parameters on several computers.
