title: Trackballcontrols or Orbitcontrols?
body: <p>First please excuse my bad english writing and please note that I am a Javascript NOOB!</p>
  
  <p>I am currently developing a website for a client where I am presenting different kind of "wood cut" in webgl but I am unable to get the desired look an feel...</p>
  
  <p>My goal is to make the viewer look and react like what we can see at Sketchfab.

  <p>The rotation is limited to a certain angle and the model always stay in the right position... With Trackballcontrols the model rotate all the way and its a mess. I have tried to change the quaternion as follow:</p>
  
  <p><strong>from:
  _this.object.up.applyQuaternion( quaternion );</strong></p>
  
  <p><strong>to:
  _this.object.up.applyQuaternion( new THREE.Vector4(0,0,0,1) );</strong></p>
  
  <p>but it behave weird when I reach a certain angle, the model become jumpy...</p>
  
  <p>Then I tried with Orbitcontrols but it seems that there is no dynamicDamping because the controls are really "dry". I prefer a smoother effect...</p>
  
  <p><strong>1-</strong> So is there a way to use Orbitcontrols and get the dynamicDamping to work?</p>
  
  <p><strong>2-</strong> Is it possible to modify Trackballcontrols to get the desired result?</p>
  
  <p>an example of my models are here:
