Farthest line segment Voronoi diagrams

Abstract:

The farthest line segment Voronoi diagram shows properties different from both the closest-segment Voronoi diagram and the farthest-point Voronoi diagram. Surprisingly, this structure did not receive attention in the computational geometry literature. We analyze its combinatorial and topological properties and outline an $O(n \log n)$ time construction algorithm that is easy to implement. No restrictions are placed upon the $n$ input line segments; they are allowed to touch or cross.
