title: Rotate camera in Three.js with mouse
body: <p>I have quite a few objects in my scene so rotating all of them could be a pain. So what is the most easy way to move camera around origin on mouse click and drag? This way all the lights, objects in the scene are in the same location, so the only thing changing is the camera. Three.js does not provide a way to rotate a camera around a point, or does it?</p>
  
  <p>Thank you</p>
