摘    要：本文提出了一种新的线裁剪原理,构造了一套全代码式的裁剪识别处理机制。它将二维、三维及四维的处理融为一体,充分地显示了用编码方式识别取代传统的几何、代数等手段识别的优越性。根据这一原理所建立的算法及程序思路简明精炼、逻辑性强,显著地提高了裁剪的速度及效率。

Abstract: This paper has presented a new approach to line clipping and built an all-code processing mechanism for clipping recognition. These measures have combined the algorithms for 2-D, 3-D and 4-D clipping into an entirety, which sufficiently shows the superiorites of the substitution of using code to recognize for the traditional geometric and algebraical ways. The algorithm which is based on the principle is sim- ple, clear and logically strict, and therefore it can increase the efficiency and speed of clipping greatly.
