摘　　要：大规模海洋模拟常用的投影网格大多为均匀网格,在实际渲染时,起伏变化较大的区域需要更多的网格来绘制才能达到较好效果,而均匀网格无法达到这一要求。为了改进这一缺陷,在改进的投影网格基础上引入曲面细分技术,依据顶点处波形的撕裂程度对网格进行细分,使得波形变化较大的区域网格更精细,细节表现更丰富。Most of the projection meshes used in large-scale ocean simulation are uniform meshes. In the actual rendering, more meshes are needed for the areas with large fluctuation to achieve better results, while uniform meshes cannot meet this requirement. In order to improve this defect, the surface subdivision technology is introduced on the basis of the improved projection mesh, and the mesh is subdivided according to the degree of wave tearing at the vertex, so that the area mesh with large wave changes is more refined and the details are more abundant.
