title: How to change the type of camera in Three.js?
body: <p>I provided a dropdown list for two cameras (Perspective and Orthographic) on the page. Right now my Three Scene is using perspective Camera. But based on the selection in dropdown list, my camera should be changed to "Orthographic" and turns to Perspective If I select Perspective in the dropdown list. How could I achieve this? Please help me.</p>
  
  <p>For detail code, Here is Jsfiddle link: <a href="http://jsfiddle.net/sagh0900/7Anag/9/" rel="nofollow">http://jsfiddle.net/sagh0900/7Anag/9/</a></p>
  
  <pre><code>camera = new THREE.PerspectiveCamera( 45, width / height, 0.1, 1000 );
  camera.position.y = 0;
  camera.position.z = 40;
  camera.lookAt(new THREE.Vector3(0, 0, 0));  
  scene = new THREE.Scene();
  scene.add(camera);
  mesh = new THREE.Mesh(new THREE.Geometry());
  scene.add(mesh);
  </code></pre>
  
  <p>Thanks in advance</p>
