摘要
一个高效实用的二维图形有效性检查方法对二维图形的设计至关重要。经过研究 ,在多边形外角和定理 [1 ]的基础上 ,采用计算轮廓增角和 (增角和指沿轮廓某一方向运动一周所摆过的角度总和 )
A highly efficient and economic method for 2D geometric figure is very important for its design. On the basis of the theorem of polygon quoin summation, an high efficient and feasible method for validity checking of 2D geometric figure outline is obtained by calculating outline angle summation.
