ABSTRACT
In a well-spaced point set the Voronoi cells all have bounded
aspect ratio, i.e., the distance from the Voronoi site to the
farthest point in the Voronoi cell divided by the distance
to the nearest neighbor in the set is bounded by a small
constant. Well-spaced point sets satisfy some important ge-
ometric properties and yield quality Voronoi or simplicial
