title: OrbitControl.js with smoother zooming and rotating?
body: <p>My demo is up <a href="http://globatum.com/testing/" rel="nofollow">here</a></p>
  
  <p>You'll notice the zooming is quite choppy. The rotating is very static.
  I'm looking to achieve similar results to <a href="http://workshop.chromeexperiments.com/globe/" rel="nofollow">Google's WebGL Globe.</a></p>
  
  <p>At first I was using the standard OrbitControl.js file </p>
  
  <p>but I wasn't liking the overall feel of it. So I started using <a href="https://gist.github.com/paulkaplan/5770247" rel="nofollow">this</a> one which 
  includes some part about momentum and such. </p>
  
  <p>I've tried embedding it but I had little luck.</p>
  
  <pre><code>// CONTROLS
  
                    cameraControls = new THREE.OrbitAndPanControls(camera, renderer.domElement);
                    cameraControls.target.set(0, 0, 0);
                                        cameraControls.maxDistance = 610;
                                        cameraControls.minDistance = 210;
                                        cameraControls.userRotateSpeed = 500;
                                        cameraControls.momentumDampingFactor = 8;
                                        cameraControls.momentumScalingFactor = 0.005;
                                cameraControls.getMouseProjectionOnBall2 = cameraControls.getMouseProjectionOnBall;
  
   cameraControls.getMouseProjectionOnBall = function(x, y){ return cameraControls.getMouseProjectionOnBall2.call(cameraControls, x, cameraControls.screen.height/2);}
  </code></pre>
  
  <p>Playing around with the numbers on the momentum lines hasn't helped much.
  Is there something I'm not doing right or is this just a limitation of the script?
  Are there any other scripts out there with a smoother feel than OrbitConrol.js?</p>
  
  <p>Note: Changing the user rotating speed parameter does nothing.
  Note2: I am basically trying to build <a href="http://stemkoski.github.io/Three.js/Shader-Halo.html" rel="nofollow">this</a>
  Notice how smooth the rotating is. I don't want to use trackballcontrol.js because it doesn't limit the rotating angle like orbitcontrol.js</p>
