space polygon meaning in English

空间多边形

This paper also analyzed some key problems in 3d triangulation from scattered points . new determining principles for the relationship of point and line in space and for convexo - concave vertices of space polygon is discussed which corrected the previous method and can be applied in space triangle mesh . at the end of this papar , the future research areaes of triangluation from 3d scattered points are demonstrated
本文还分析了三维空间直接三角剖分所要解决的一些关键问题，进而提出了空间中点与直线位置关系判别的新方法及空间多边形顶点凹凸性判别的新方法，修正了以往算法在应用上的局限性，使之能够适用于复杂网格多边形边界。
