ITK/Examples/SimpleOperations/DistanceBetweenPoints

Compute the distance between two 3D points. This can easily be extended to ND by changing the Point template parameter.

DistanceBetweenPoints.cxx

<source lang="cpp">

1. include "itkPoint.h"

1. include <iostream>
2. include <string>

int main(int, char *[]) {

 itk::Point<double,3> p0;
 p0[0] = 0.0;
 p0[1] = 0.0;
 p0[2] = 0.0;

 itk::Point<double,3> p1;
 p1[0] = 1.0;
 p1[1] = 1.0;
 p1[2] = 1.0;

 double dist = p0.EuclideanDistanceTo(p1);
 std::cout << "Dist: " << dist << std::endl;

 return EXIT_SUCCESS;
