Class RibbonIterator

java.lang.Object
  com.bbn.openmap.geo.RibbonIterator

All Implemented Interfaces:

java.lang.Iterable<Ribbon>, java.util.Iterator<Ribbon>

public class RibbonIterator
extends java.lang.Object
implements java.util.Iterator<Ribbon>, java.lang.Iterable<Ribbon>

Iterate along a sequence of Ribbons. A Ribbon is a three Geo set, with a RIGHT, CENTER and LEFT Geo in the Ribbon. The location of the LEFT and RIGHT Geo are perpendicular to the great circle path that the CENTER Geo resides on.

Constructor Detail

RibbonIterator

public RibbonIterator(Geo v1,
                      Geo v2,
                      double radius)

Return an iterator that returns Ribbons along the great circle between v1 and v2. The Ribbon points are radius radians apart, and each Ribbon is 2*radius apart.

RibbonIterator

public RibbonIterator(Geo v1,
                      Geo v2,
                      double radius,
                      double rotationIntervalDist)

Return an iterator that returns Ribbons along the great circle between v1 and v2. The Ribbon points are radius radians apart, and each Ribbon is rotationIntervalDist apart.

Parameters:

v1 - from this Geo

v2 - to this Geo

radius - distance away from great circle lines between geos, in radians.

rotationIntervalDist - interval distance between ribbons, in radians. You want this to be smaller than the distance between the geos, obviously.
