裁剪区域 meaning in English

clipping region

Moreover , based on in - depth research of " the existing scan - line polygon fill algorithm , the author has introduced a new fast method for clipping arbitrary boundary areas algorithm which uses the edge consistency and the scan - line consistency and adopts sorted chain table , i t can reduce the quantity of calculating intersection points and improve the efficiency of algorithm
另外，作者在对已有的扫描线填充算法深入研究的基础上，介绍一种利用裁剪区域的边的连贯性和扫描线的连贯性，从而减少求交计算量、提高算法效率的有序链表的快速裁剪算法。
