Improved method for calculating no-fit polygon based on Ghosh''s slope diagram
一种基于Ghosh斜率图法的改进的临界多边形生成算法*

This paper presented and brings about an improved and more efficient method to calculate the NFP,and this new method improved the edge s'traverse pattern,simplified the component of NFPList,raised the efficiency of calculating the outer contour.Simulation experiment verify this algorithm further.
