【摘要】 对基于STL模型的切片处理技术进行了深入分析,并在吸收现有算法优点的基础上,提出了分组排序、对边求交的分层算法。该算法先根据三角面片中顶点在分层方向的最大坐标值和最小坐标值对各面片进行排序并形成分层关系矩阵,然后对每层的三角面片采用对边依次追踪求交的方法生成切片轮廓数据。实际应用表明,该算法具有高效、稳定和可靠等优点。更多还原

【Abstract】 On the basis of analyzing the slicing technology and absorbing the merit of current algorithms for slicing,a new algorithm was put forward.In the strategy,the grouping matrix was established by sorting for the triangular facets according to the minimum and maximum z-axis value of the triangular facets.Then the contour segments were generated by marching from edge to edge.Applications are made to show that the approach is efficient,stable and reliable.更多还原
