| 摘 要： | 通常的二维布尔运算只适用于封闭的轮廓线，无法应用于任意类型的曲线．本文在分析了二维封闭轮廓线布尔运算的基础上，给出了基于曲线交点处局部邻域的曲线分类方法，并由此得到任意曲线间的布尔运算，来自动生成所需的轮廓线，这种方法还可以推广到三维设计．

| Abstract: | Conventional 2D boolean operations are only suitable for closed profiles, not for arbitary curves. By means of the analysis of 2D boolean operations for closed profiles, this paper introduces a new curve classification method based on the local neighborhood of the curve intersection point, and then presents the boolean operations for arbitrary curves to generate profiles automatically. This new method can also be extended to 3D surface design. |
