Triangle mesh models have been established as the most general and flexible schemes to represent complex surface models in the area of reverse engineering ( re ) , rapid prototyping manufacturing ( rpm ) , numerical control ( nc ) programming , 3d animation , etc . but the models reconstructed from real - world data may contain unavoidable noise and many narrow triangles , so the models must be optimized and modulated under given tolerances
三角网格模型是逆向工程、快速原型制造、数控加工编程、三维动画等技术中常用的模型表示方法，模型的质量直接影响到产品的质量，尤其在逆向工程中，直接通过测量数据得到高质量的网格模型几乎是不可能的。因为，测量数据中不可避免地存在各种噪声和扰动，因此在满足几何精度要求的前提下，对网格模型进行优化调整，以提高模型质量就十分必要。
