Package sc.fiji.snt

Class NearPoint

java.lang.Object
sc.fiji.snt.NearPoint
All Implemented Interfaces:
Comparable<NearPoint>
public class NearPoint extends Object implements Comparable<NearPoint>
This class encapsulates the relationship between an arbitrary point (nearPoint.x,nearPoint.y,nearPoint.z) close to a particular point on a particular path. The important method here is distanceToPathNearPoint() which retrieves the distance to the nearest point on the line segments on either side of the path point, rather than just the point. Also, it will return null if the point appears to be "off the end" of the Path.
