Abstract

The relative neighborhood graph for a finite set S={p1,...,pN} of points, briefly RNG(S), is defined by the following formation rule: pipj is an edge in RNG(S) if and only if for all pkε{lunate}S-{pi, pj}, dist(pi, pj)≤max(dist(pi,pk), dist(pj,pk)). We show that RNG for point sets in R3 can be constructed in optimal space and O(N2log N) time. Also, combinatorial estimates on the size of RNG in R3 are given.
