摘要
视图轮廓信息和封闭图形信息在图形处理中有着重要的作用.该文提出基于顺时针行走方向搜索外轮廓下一条路径和基于逆时针行走方向搜索封闭图形下一条路径的原理和算法,改进了以往算法的不足,对提高CAD系统的图形生成效率以及系统的智能化程度等方面有着重要的意义.
The outline information and closed graph information of view plays an important role in processing graphics.The paper provides a method,which can automatically search next path of outline based on clockwise tread and search next path of closed graph based on counter－clockwise tread.The method improves the ancient method and increases graph making efficiency and intelligentize of CAD system.
