title: Orthographic Camera and pickingRay?
body: <p>I tried to implement a function to select and move objects in a stage compound of an orthographic camera.</p>
  
  <p>I'd like to get the same example as : <a href="http://threejs.org/examples/webgl_interactive_draggablecubes.html" rel="nofollow noreferrer">http://threejs.org/examples/webgl_interactive_draggablecubes.html</a></p>
  
  <p>but not with perspective camera.</p>
  
  <p>I already replaced  :</p>
  
  <pre><code>var camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 1000 );
  </code></pre>
  
  <p>with : </p>
  
  <pre><code>var camera =  new THREE.OrthographicCamera(window.innerWidth / -zoom, window.innerWidth / zoom, window.innerHeight / zoom, window.innerHeight / -zoom, -1000, 1000);
  </code></pre>
  
  <p>and replaced this :</p>
  
  <pre><code>var ray = new THREE.Raycaster( camera.position, vector.sub( camera.position ).normalize() );
  </code></pre>
  
  <p>by this :</p>
  
  <pre><code>var ray = projector.pickingRay( vector, camera );
  </code></pre>
  
  <p>But, it does not seem to be enough to run.</p>
  
  <p>So, what's it lack ?</p>
  
  <p>Is it possible to use Projector and Ray with OrthographicCamera ??</p>
  
  <p>Thanks.</p>
