title: can't see obj in three.js
body: <p>I have a 3D model that i exported from meshlab and want to load it in three.js like this:</p>
  
  <pre><code>var scene = new three.Scene();
  scene.background = new THREE.Color( 0xffffff );
  var camera = new three.PerspectiveCamera(75, window.innerWidth/window.innerHeight, 0.1, 1000);
  
  var renderer = new three.WebGLRenderer({ alpha: true });
  renderer.setSize(window.innerWidth, window.innerHeight);
  
  document.body.appendChild(renderer.domElement);
  var mesh = null;
  var material = new THREE.MeshBasicMaterial({color: 'yellow', side: THREE.DoubleSide});
  function initMesh() {
      var loader = new THREE.OBJLoader();
      loader.load('merged.obj', function(obj) {
  
          obj.traverse(function (child) {
  
              if (child instanceof THREE.Mesh) {
                  child.material = material;
              }
  
          });
      mesh = new THREE.Mesh(obj);
      mesh.name = 'mesh1';
      scene.add(mesh);
      });
  }
  </code></pre>
  
  <p>But i cannot see the model. I tried changing back ground colors and the color of the mesh, but i'm not sure the object is in the scene.</p>
  
  <p>The camera in Meshlab has the following viewpoint: </p>
  
  <pre><code>&lt;!DOCTYPE ViewState&gt;
  &lt;project&gt;
   &lt;VCGCamera TranslationVector="13.2236 38.6958 -15.7741 1"

   &lt;Render Lighting="0" DoubleSideLighting="0" SelectedVert="0" 
  ColorMode="3" SelectedFace="0" BackFaceCull="0" FancyLighting="0" 
  DrawMode="2" TextureMode="0"/&gt;
  &lt;/project&gt;
  </code></pre>
  
  <p>Do i have to change the settings of my camera?</p>
  
  <p>EDIT:
  the OBJ file can be found at: <a href="https://files.fm/u/e5n2u4dq" rel="nofollow noreferrer">https://files.fm/u/e5n2u4dq</a></p>
  
  <p>More debugging showed that loader.load() is never executed, but i can't figure out what's wrong</p>
