title: ThreeJS: update camera FOV
body: <p>I'm trying to update a camera field of vision without creating a new camera.  I've been able to do this with position by using the code below:</p>
  
  <pre><code>camera.position.set()
  </code></pre>
  
  <p>I'd like to set this up in a similar way with the fov:</p>
  
  <pre><code>camera.fov.set()
  </code></pre>
  
  <p>This isn't working in the script.  Can anyone else suggest a quick method?</p>
