空间多边形 meaning in Chinese

space polygon

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。
Abstract : basing on the introduction of brim - vector and face - vector , by means of analogy , the paper popularizes the cosine - theorem from flat - triangle to vacuum - polygon and arbitrary - polyhedron , concludes a series of generalized cosine - theorems which have symmetric and conformable form , and presents short and strict proof
文摘:在引入边矢量及面矢量概念的基础上，以类比作为手段，对余弦定理进行由平面三角形到空间多边形乃至任意多面体的一系列推广，得出了形式对称一致的一组广义余弦定理，并给出了其简捷严谨的证明。
