简单多边形的测地最远点沃罗诺伊图

The Geodesic Farthest-point Voronoi Diagram in a Simple Polygon

Eunjin Oh, Luis Barba, Hee-Kap Ahn

摘要:

给定简单多边形中的一组点位置,测地最远点沃罗诺伊图将多边形划分为单元,每个位置至多一个单元,使得单元中的每个点相对于测地度量具有相同的最远位置。本文提出了一种计算简单$n$ -边形中$m$点的测地线最远点沃罗诺伊图的$O(n\log\log n+m\log m)$ -时间算法。这改进了以前最著名的算法由Aronov等人[离散计算。9(3):217-255,1993]。在所有点位都在简单多边形边界上的情况下,我们可以在$O((n + m) \log \log n)$时间内计算测地线最远点沃罗诺伊图。

英文摘要:

Given a set of point sites in a simple polygon, the geodesic farthest-point Voronoi diagram partitions the polygon into cells, at most one cell per site, such that every point in a cell has the same farthest site with respect to the geodesic metric. We present an $O(n\log\log n+m\log m)$- time algorithm to compute the geodesic farthest-point Voronoi diagram of $m$ point sites in a simple $n$-gon. This improves the previously best known algorithm by Aronov et al. [Discrete Comput. Geom. 9(3):217-255, 1993]. In the case that all point sites are on the boundary of the simple polygon, we can compute the geodesic farthest-point Voronoi diagram in $O((n + m) \log \log n)$ time.
