An Efficient Algorithm for the Three-Dimensional Diameter Problem

Abstract: We explore a new approach for computing the diameter of n points in R3 that is based on the restriction of the furthest-point Voronoi diagram to the convex hull. We show that the restricted Voronoi diagram has linear complexity. We present a deterministic algorithm with O(nlog2n) running time. The algorithm is quite simple and is a good candidate to be implemented in practice. Using our approach the chromatic diameter and all-furthest neighbors in R3 can be found in the same running time.
