摘要: We show that the wavefront approach to Voronoi diagrams (a deterministic line-sweep algorithm does not use geometric transform) can be generalized distance measures more general than Euclidean metric. In fact, we provide first worst-case optimal (O (n logn) time,O(n) space) is valid for full class of what has been callednice metrics in plane. This also solves previously open problem providing anO (nlogn)-time plane-sweep arbitraryL k -metrics. Nice include all convex functions but like Moscow metric, and composed metrics. The conceptually simple, it copes with possible deformations diagram.
