title: Algorithm for calculating a distance between 2 3-dimensional points?
body: <p>I have two 3-D points.<br>
  Example:</p>
  
  <pre><code>float[] point1 = new float[3] {1.3919023, 6.12837912, 10.391283};
  float[] point2 = new float[3] {48.3818, 38.38182, 318.381823};
  </code></pre>
  
  <p>Anyone an idea for an algorithm to calculate the distance in float between the points?</p>
