spherical polygon

An algorithm of determining the minimum convex spherical polygon is presented .

继而给出星下点最小凸球面多边形的判定算法；

A spherical polygon formed by the arcs of 3 great circles .

由三个大圆的一些弧线所形成的球形多边形。

An approach is first posed by using gnomonic projection , based on the problem remaining unresolved , which is about the coating joint modeling and the joint overlap of spherical equilateral polygon .

针对球面等边多边形包覆拼接建模及出现拼接重叠等问题，分析了心射球面投射原理和共球面等边多面体的结构特征，提出了共球面等边多面体作心射球面投射的方法。

The paper applies the theory of spherical and spatial polygon to analyse the position problems ef 28 different kinds of 3R-3P robot manipulators or 4R-3 P spatial linkage mechanisms . It can control the computation process reasonably and effectively .
