Abstract
The currently known sweep-line algorithm for constructing the nearest neighbor Voronoi diagram uses geometric transformation. This thesis presents another sweep-line algorithm without using geometric transformation. The algorithm conceptually consists of two steps. In the first step, two planar graphs called Left-Right Partial Voronoi Graph (LR-PVG) and Right-Left Partial Voronoi Graph (RL-PVG) are constructed in O(n log n) time and O(n) space using the two plane sweeps, where n is the number of points in the given point set. In the second step, a top-down non-recursive version of the divide-and-conquer method is used to merge LR-PVG and RL-PVG into the final Voronoi diagram in O(n log n) time and O(n) space.
