摘　　要：提出了基于海浪谱的快速Fourier变换的大范围深海场景的建模方法.针对海浪三维结构上的缺陷,计算出用于水面网格变形的顶点三维数据,还计算出用于水面光照计算的表面法向量和切向量,将得到的高度场数据平铺到可见区域的网格上,以模拟出整个可见海面的波浪效果.该方法能够区分杂乱的海浪细微轮廓,可以很好的完成海浪的三维模拟,最终改进了三维海浪仿真的真实感和清晰度,达到了令人满意的效果.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
