摘　　要：二维周期图形在工艺美术、纺织、广告等领域有着重要的应用背景．本文提出了一种基于基元图形的周期图形处理方法．基元图形由于其拓扑特性的改变，使得现有二维图形学的一些概念和方法不能直接地应用．为此，本文讨论了基元图形的性质，并在此基础上提出了基元图形处理的一些概念和实现方法，将该方法用于实际提花ＣＡＤ系统，获得了满意的结果．Two dementional periodic patterns have found a lot of applications in industrial arts,textile industry, advertisments, etc. A periodic graphics processing method has been proposed based on the basic element (BE) of periodic pattern.Because of the changes of the topological properties of the BE, the concept and the algorithms in existence cannot be used directly. So the properties of the BE has been discussed and the new concept and algorithms for BE processing have been proposed. The method has been used successfully in a jacquard fabric CAD system.
