title: How to get the global/world position of a child object?
body: <p>How do I get the global position of an Object3D inside another Object3D?</p>
  
  <p><strong>setup:</strong></p>
  
  <pre><code>var parent = new THREE.Object3D();
  parent.position.set(100, 100, 100);
  
  var child = new THREE.Object3D();
  child.position.set(100, 100, 100);
  parent.add(child);
  
  scene.add(parent);
  </code></pre>
  
  <p><strong>notes:</strong></p>
  
  <p>I thought that this would be the way to do it:</p>
  
  <pre><code>console.log(child.localToWorld(parent.position));
  </code></pre>
  
  <p>...but it gives me <em>(100, 100, 100)</em>, not <em>(200, 200, 200)</em>.</p>
