		<h1>[name]</h1>

		<div class="desc">
      Orbit controls allow the camera to orbit around a target.<br>

      To use this, as with all files in the /examples directory, you will have to
      include the file seperately in your HTML.

		</div>


		<h2>Example</h2>

		<div>[example:misc_controls_orbit misc / controls / orbit ]</div>

		<code>
var renderer = new THREE.WebGLRenderer();
renderer.setSize( window.innerWidth, window.innerHeight );
document.body.appendChild( renderer.domElement );

var scene = new THREE.Scene();

var  camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 10000 );

var controls = new THREE.OrbitControls( camera );

//controls.update() must be called after any manual changes to the camera's transform
camera.position.set( 0, 20, 100 );
controls.update();

function animate() {

  requestAnimationFrame( animate );

  // required if controls.enableDamping or controls.autoRotate are set to true
  controls.update();

  renderer.render( scene, camera );

}
		</code>

		<h2>Constructor</h2>

		<h3>[name]( [page:Camera object], [page:HTMLDOMElement domElement] )</h3>
		<div>
      [page:Camera object]: (required) The camera to be controlled.<br><br>

      [page:HTMLDOMElement domElement]: (optional) The HTML element used for event listeners. By default this is the whole document,
      however if you only want to the controls to work over a specific element (e.g. the canvas) you can specify that here.
		</div>


    <h2>Properties</h2>

    <h3>[property:Boolean autoRotate]</h3>
    <div>
      Set to true to automatically rotate around the target.<br> Note that if this is enabled, you must call [page:.update]
      () in your animation loop.
    </div>

    <h3>[property:Float autoRotateSpeed]</h3>
    <div>
      How fast to rotate around the target if [property:Boolean autoRotate] is true. Default is 2.0, which equates to 30 seconds
      per rotation at 60fps.<br> Note that if [property:Boolean autoRotate] is enabled, you must call [page:.update]
      () in your animation loop.
    </div>

    <h3>
      [property:Float dampingFactor]</h3>
    <div>
      The damping inertia used if [property:Boolean enableDamping] is set to true.<br> Note that for this to work, you must
      call [page:.update] () in your animation loop.
    </div>

    <h3>[property:HTMLDOMElement domElement]</h3>
    <div>
      The HTMLDOMElement used to listen for mouse / touch events. This must be passed in the constructor; changing it here will
      not set up new event listeners. Default is the whole document.
    </div>

    <h3>[property:Boolean enabled]</h3>
    <div>
      Whether or not the controls are enabled.
    </div>

    <h3>[property:Boolean enableDamping]</h3>
    <div>
      Set to true to enable damping (inertia), which can be used to give a sense of weight to the controls. Default is false.<br>          Note that if this is enabled, you must call [page:.update] () in your animation loop.
    </div>

    <h3>[property:Boolean enableKeys]</h3>
    <div>
      Enable or disable the use of keyboard controls.
    </div>

    <h3>[property:Boolean enablePan]</h3>
    <div>
      Enable or disable camera panning. Default is true.
    </div>

    <h3>[property:Boolean enableRotate]</h3>
    <div>
      Enable or disable horizontal and vertical rotation of the camera. Default is true.<br>
      Note that it is possible to disable a single axis by setting the min and max of the
      [page:.minPolarAngle polar angle] or [page:.minAzimuthAngle azimuth angle] to the same value,
      which will cause the vertical or horizontal rotation to be fixed at that value.
    </div>

    <h3>[property:Boolean enableZoom]</h3>
    <div>
      Enable or disable zooming (dollying) of the camera.
    </div>

    <h3>[property:Float keyPanSpeed]</h3>
    <div>
      How fast to pan the camera when the keyboard is used. Default is 7.0 pixels per keypress.
    </div>

    <h3>[property:Object keys]</h3>
    <div>
      This object contains references to the keycodes for controlling camera panning. Default is the 4 arrow keys.
      <code>
controls.keys = {
  LEFT: 37, //left arrow
  UP: 38, // up arrow
  RIGHT: 39, // right arrow
  BOTTOM: 40 // down arrow
}
       </code> See [link:https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/keyCode this page] for a full
      list of keycodes.
    </div>

    <h3>[property:Float maxAzimuthAngle]</h3>

      Infinity;
    </div>

    <h3>[property:Float maxDistance]</h3>
    <div>
      How far you can dolly out ( [page:PerspectiveCamera] only ). Default is Infinity.
    </div>

    <h3>[property:Float maxPolarAngle]</h3>
    <div>
      How far you can orbit vertically, upper limit. Range is 0 to Math.PI radians, and default is Math.PI.
    </div>

    <h3>[property:Float maxZoom]</h3>
    <div>
      How far you can zoom out ( [page:OrthographicCamera] only ). Default is Infinity.
