QuadEdgeSubdivision.getPrimaryEdges介绍

[英]Gets all primary quadedges in the subdivision. A primary edge is a QuadEdgewhich occupies the 0'th position in its array of associated quadedges. These provide the unique geometric edges of the triangulation.
[中]获取细分中的所有主四边形边。主边是一个四边形，它在其关联四边形数组中占据第0位。它们提供了三角剖分的唯一几何边。
