摘　　要：在画出隐藏线的立体线图中,阐述了以线图外轮廓线的确定为目标的不完整立体线图的标记方法。根据L型节点与W型、Y型节点之间的26种对应关系给出了节点对的匹配规则和补线算法,并用VC编程实现。实验结果表明该算法能使计算机模拟人的思维,有效地补画不完整的立体线图。In 3D line drawing which has hidden lines displayed, a labeling method for imperfect line drawing aiming for searching external contour lines is described. According to 26 relations between L junctions and W, Y junctions, the matched rules and the algorithms of making up missed lines for pairs of junctions are suggested and programmed by VC. The example shows that the algorithm can let the computer simulates the human＇s thinking and makes up missed lines for imperfect line drawing effectively.
