由Alexandrov定理导出的平面多面体

On Flat Polyhedra deriving from Alexandrov's Theorem

Joseph O'Rourke

摘要:

我们表明,有一个简单的算法来确定是否多面体保证存在的亚历山德罗夫的胶合定理是一个退化的平面多面体,并重建它的胶合指令。对于由n个标签指定粘合的多边形,该算法的运行时间为O(n^3)。

英文摘要:

We show that there is a straightforward algorithm to determine if the polyhedron guaranteed to exist by Alexandrov's gluing theorem is a degenerate flat polyhedron, and to reconstruct it from the gluing instructions. The algorithm runs in O(n^3) time for polygons whose gluings are specified by n labels.
