title: Three.js Device Orientation Controls: Limit or disable XY rotations
body: <p>I'm using DeviceOrientationControls to attach to and rotate an Object in Three.js</p>
  
  <p>By default, these controls will rotate the object on all three of the XYZ axes.</p>
  
  <p>Is there any way to disable rotation on the X and Y axes, so that the object only responds to rotation on the Z axis?</p>
  
  <p>Hope that's clear enough, let me know if you need an example. Thanks.</p>
