［摘要］自由曲面作為現(xiàn)代建筑的重要特征，越來越多地出現(xiàn)代建筑設計中，而如何在自由曲面上布置高質量的網格卻始終是一個困難且復雜的問題。就這一問題提出了基于桿長均勻性的網格優(yōu)化方法，詳細介紹了該方法的基本流程和要點，并基于Rhino+Grasshopper平臺編制了網格優(yōu)化程序。通過三個優(yōu)化實例證明了該方法簡單易行、適用性強、效果理想，且能始終保證優(yōu)化過程中網格與曲面的完美貼合。

Abstract:As an important feature of modern architecture, more and more free-form surfaces appeared in architectural design. However, it was a difficult and complex problem how to arrange high-quality mesh on free-form surface. A mesh optimization method based on uniformity of mesh edges′ length was proposed. The basic process and key points of this method were introduced in detail, and a mesh optimization program was developed based on Rhino + Grasshopper. Through three examples, it shows that this method is simple, practical, effective, and could always keep the vertices of the mesh on the reference surface during the optimization process.
Keywords:free-form surface; grid optimization; Rhino software; topology structure
