摘　　要：对基于STL数据模型的分层处理技术进行了深入分析,并在研究现有算法的基础上,提出了一种新的高效分层切片算法。先对逐个面片求出所有会被切到的交点并储存在面片信息中,再对面片分组排序,利用交点相邻以及上、下层间的继承关系来提高求切片轮廓数据的效率。实际应用表明,该算法高效、稳定而且可靠。On the base of deep analysis of slicing technology and the study of current algorithms,a new algorithm was put forward.In this strategy,all the intersection points of every triangular facet were calculated and storaged,then the grouping matrix of the triangular facets was established.At last,the slicing profile data were obtained by using the inheritance relationship and adjacent intersections.This method can greatly improve the efficiency of computing the slicing profile data.Actual application shows that the algorithm is efficient,stable and reliable.
