Summary: Divide-and-Conquer for Voronoi Diagrams Revisited
We propose a simple and practical divide-and-conquer
algorithm for constructing planar Voronoi diagrams.
The novel aspect of the algorithm is its emphasis on
the top-down phase, which makes it applicable to sites
of general shape.
The divide-and-conquer paradigm gave the first opti-
mal solution for constructing the closest-site Voronoi
diagram in the plane . Though being a classical
example for applying a powerful algorithmic method
in computational geometry, the resulting algorithm
