摘　　要：STL文件描述的是一种离散的实体表面三角面片模型,模型中的所有三角面片是无序的,也不存在拓扑信息。然而在许多应用系统,需要借助模型的拓扑关系进行分析,以快速、准确地操作模型数据。重点研究STL网格模型的拓扑重构问题,在读取STL文件几何信息基础上,分析ACIS模型的数据结构,确定重构模型的拓扑结构,通过ACIS平台提取所需的拓扑信息,实现STL网格模型到ACIS的拓扑模型的重构。最后,通过实例验证重构算法的正确性。STL farmat is a kind of solid model which consists of discrete surface triangle face. All of the triangular mesh of the models are disordered and do not exist any topology information. However, it is necessary for many application systems to perform any analysis with topological relationship, so as to operate STL model rapidly and precisely. It focuses on the problem of STL mesh model topology reconstruction. Based on the STL model in the ACIS platform, it analyzed the data structure of the ACIS model, and determined the topological structure of the reconstructed model. Through the extracting of the topological information from the ACIS platform, the topological model can be reconstructed from STL mesh model. Finally, the reconstructing algorithm is verified through one model example.
