distance static method

double distance(List<double> p1, List<double> p2)

Find the distant between p1 and p2

Implementation

static double distance(List<double> p1,List<double > p2 ){
  double  xd = p2[0]-p1[0];
  double  yd = p2[1]-p1[1];
  double  zd = p2[2]-p1[2];
  return math.sqrt(xd*xd + yd*yd + zd*zd);
}
