title: THREE.js rotating camera around an object using orbit path
body: <p>I am struggling in solving this problem.</p>
  
  <p>On my scene, I have a camera which looks at the center of mass of an object. I have a some buttons that enable to set camera position on particular view (front view, back view,...) along a invisible sphere that surroung the object (constant radius).</p>
  
  <p>When I click on the button, i would like the camera to move from its start position to the end position along the sphere surface. When camera moves I would like it to keep fixing center of mass of the object.</p>
  
  <p>Has anyone have a clue on how to achieve this?</p>
  
  <p>Thanks for help!</p>
