本文引入平面面基域分划技术，首先将窗口与被裁剪形状分拆成面基域，再对各个面基域进行包含性测试。从而产生裁剪结果。该算法能够实现平面上由任意直线段和曲线段围成的，单连通或多连通域内的任意二维图形在任意窗口内裁剪，因而功能较齐全。作为这一算法的应用，本文给出了基于该裁剪技术的平面图形消隐算法。
In this paper, we introduce a plane-based domain partitioning technique, which first splits the window and the cropped shape into surface-based domains, and then performs inclusive testing on each of the surface-based domains. Resulting in cropping results. This algorithm can realize the complete function by cutting any arbitrary two-dimensional graph which is surrounded by arbitrary straight line segment and curved segment in the plane and is connected in single or multiple connected domains. As an application of this algorithm, this paper presents a planar graphics blanking algorithm based on the clipping technique.
