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
三角網格模型是逆向工程、快速原型製造、數控加工編程、三維動畫等技術中常用的模型表示方法，模型的質量直接影響到產品的質量，尤其在逆向工程中，直接通過測量數據得到高質量的網格模型幾乎是不可能的。因為，測量數據中不可避免地存在各種噪聲和擾動，因此在滿足幾何精度要求的前提下，對網格模型進行優化調整，以提高模型質量就十分必要。 -
