Abstract: Put forward based on the fast Fourier transform wave spectrum large areas of the deep sea scene drawing method.According to the waves 3D structural flaws,calculate the water deformation of the grid vertex 3D data,also calculated for the water surface of the lighting calculation method of vector and cut vector,receive the height of the field data of visible region,to simulate the visible the sea waves.The method can distinguish between mixed and disorderly waves,well outline fine finish the waves of three dimensional simulation,and ultimately improve the 3D simulation waves clarity,get a satisfactory effect
