org.opentripplanner.visibility.VisibilityPolygon

public class VisibilityPolygon
extends VLPolygon

Ported by David Turner from Visilibity, by Karl J. Obermeyer This port undoubtedly introduced a number of bugs (and removed some features). Bug reports should be directed to the OpenTripPlanner project, unless they can be reproduced in the original VisiLibity
