Given a set of points P = {p(1), p(2), . . . , p(n)} in the Euclidean plane, with each point p(i) associated with a given direction v(i) is an element of V. P(p(i), v(i)) defines a half-plane and L(p(i), v(i)) denotes the baseline that is perpendicular to v(i) and passing through p(i). Define a region dominated by p(i) and v(i) as a Baseline Bounded Half-Plane Voronoi Region, denoted as V or(p(i), v(i)), if a point x is an element of V or(p(i), v(i)), then (1) x is an element of P(p(i), v(i)); (2) the line segment l(x, p(i)) does not cross any baseline; (3) if there is a point p(j), such that x is an element of P(p(j), v(j)), and the line segment l(x, p(j)) does not cross any baseline then d(x, p(i)) <= d(x, p(j)), j not equal i. The Baseline Bounded Half-Plane Voronoi Diagram, denoted as V or(P, V), is the union of all V or(p(i), v(i)). We show that V or(p(i), v(i)) and V or(P, V) can be computed in O(n log n) and O(n(2) log n) time, respectively. For the heterogeneous point set, the same problem is also considered. |
