2 Convex Polygons We can easily extend the sites from line segments to convex polygons. Let Q = {p1 , p2 , . . , pn } be a set of n convex polygonal sites, each having at most k sides, and let NVDP (Q) be the nearest-site Voronoi diagram of these sites with respect to the convex polygon-oﬀset distance function DP , where P is an msided convex polygon. With similar arguments given for Lemmata 3 and 5 for the nearest-site Voronoi diagram of a set of line segments (with respect to DP ), we can prove the following.

In the same manner, the following generalizes Lemma 6 to deal with polygonal sites. Voronoi Diagram for Convex Polygonal Sites 33 Lemma 11 (i) The bisecting curve BP (p1 , p2 ) of a pair of convex polygons p1 , p2 , each having at most k sides, is a polyline with O(m + k) arcs and segments. (ii) Two such bisecting curves intersect O(m + k) times. The proof of the lemma above is identical to that of Lemma 6 with the following reﬁnements. 1. The oﬀset of P can touch any of the up to k corners and k sides of each of the sites.
