摘　　要：分析了海面特点和仿真分类,用随机海浪理论和分形理论相结合的方法,实现了开阔深水海域的三维海面实时动态仿真.该方法首先采用局部振幅和相位函数表示方法对边缘海域海面进行建模;然后,利用分形理论的迭代生成原则和自相似原则,采用钻石—方块算法对中间海域海面进行插值填充.三维海面的虚拟仿真结果表明,所提方法具有实时、逼真的仿真效果.The characteristics of the sea surface and the classification of the sea surface simulation technolo-gy are analyzed.By using the combination of the random wave theory and the fractal theory,the re-al-time dynamic simulation of the three-dimensional sea surface in the open-deep area of the seais realized.The method firstly uses the local amplitude and phase function modeling method forthe edge of sea surface;secondly,according to the iterative generating principle of fractal theoryand the principle of self-similarity,using diamond-square algorithm for middle sea surface inter-polation filling.The virtual simulation results of 3D sea surface show that the proposed method hasreal-time and realistic simulation results.
