摘    要:通过对STL文件结构的分析,引入无向图数据结构,建立了三角形网格之间的毗邻关系,以顺利进行三角形网格的查寻,实现分层切片,对分层切片算法进行了研究,讨论了切片过程中可能出现的问题,提出了相应的解决办法,最后建立了双向链表来表示切片后的CAD模型截面轮廓。

关 键 词:STL文件  切片算法  毗邻关系  三角形网格  CAD

Abstract:By the analysis of the structures of STL files and based on the structure of undiagraph, the adjoining relationship among the triangles is constructed by which one can search for a triangle and slice easily. A slicing algorithm is studied and the problems which may happen during the slicing process are discussed. Some methods to solve the problems are proposed too. At last, a Double Link List is used to express the CAD mold after slicing.
Keywords:rapid prototype  STL file  slicing algorithm
