title: Camera's position not changing when added to a mesh
body: <p>I want to realise a little TPS (the camera follow the player). I add the camera to a cube ( wich represents the players when he moves), and show the coordinates of the camera and the cube in : <a href="http://jsfiddle.net/bvbg2wuk/2/light/" rel="nofollow">this fiddle</a>. The Camera is following the cube as well, but you can see that the camera coordinates are not changing. There is no problems but when i want to use the picking, the coordinates are wrong because it depends on the camera. </p>
  
  <p>I just do that :</p>
  
  <pre><code>cube.add(Camera);
  </code></pre>
  
  <p>Somebody have an idea ? </p>
