getEuclidean

public static ClusterElementFunctions<ComponentLine3D> getEuclidean()

distance

public double distance(ComponentLine3D element1,
                       ComponentLine3D element2)

Specified by:

distance in interface ClusterElementFunctions<ComponentLine3D>

distance

public double distance(Point3d[] points1,
                       Point3d[] points2)

euclideanLineDistance

public static double euclideanLineDistance(Point3d[] line1,
                                           Point3d[] line2)

Computes the distance between two lines in terms of absolute distances between single segments.

getNextValidPoint

private static Point3d getNextValidPoint(Point3d[] line,
                                         int index)
