这是一种三角形面片简化算法，此算法可以将复杂的三维模型化简，由几万、几十万的三角形化简到几万、几千甚至几百个三角形，同时保持与原模型最大的相似度。此算法可以用来化简模型，也可以用来生成游戏编程中LOD(level of detail)技术所需要的特殊格式的模型文件。-This is a triangular patch simplified algorithm that can simplify the complex three-dimensional model, by the tens of thousands, hundreds of thousands of simplification of the triangle to the tens of thousands, even hundreds of thousands of triangles, while maintaining the original model with the largest similarity. This algorithm can be used to simplify model can also be used to generate the game programming LOD (level of detail) the special needs of technology model file format.
