摘 要:从图形区域化描述及图素定向方面着手,引入特征值概念,对采矿计算机辅助设计中的多边形运算进行了全面研究.给出了简化多边形运算的计算公式,讨论了多边形算法构造的一般过程.最后给出了通用多边形运算算法,并用实例进行了验证.
Abstract: Based on the description of graph area and direction of the basic graph element, and by introducing the nodical eigenvalue conception, the polygon operation in mining CAD system was studied in great detail. The calculating formulas used to simplify the polygon operation were given. The general procedure of polygon algorithm formation was discussed' Finally,the global algorithm of polygon operation was given, and it was proved by an example.
