有序点集与无序点集的曲面重构方法比较

摘要

In the field of reverse engineering, surface reconstruction refers to the operation to obtain the approximate surface of an object by making use of a set of points on it. This technique is also applicable to the design of non-standard buildings. For reconstructing free form surface, there are two basic methods based on ordered points and disordered points. This paper has made a comparative study on it. Two different approaches derived from it generate a double layer surface consisting of surface and supporting structure. It shows the feasibility of applying this technique in the field of architectural design.%曲面重构在逆向工程领域是指利用物体表面的点集重新构建物体形状的操作,这一技术对于非标准建筑设计同样适用.从已知排列顺序的点集(有序点集)和未知排列顺序的点集(无序点集)出发,对自由曲面进行重构是曲面重构的两种基本方法.本文对此进行了对比研究,并由这两种出发点,生成包含表皮及支撑结构的双层曲面系统,验证了该技术在建筑设计领域应用的可行性.
