+		<h1>[name]</h1>
+
+		<p class="desc">
+		Arcball controls allow the camera to be controlled by a virtual trackball with full touch support and advanced navigation functionality. <br>
+		Cursor/finger positions and movements are mapped over a virtual trackball surface
+		represented by a gizmo and mapped in intuitive and consistent camera movements. 
+		Dragging cursor/fingers will cause camera to orbit around the center of the trackball in a conservative way (returning to the starting point
+		will make the camera to return to its starting orientation).<br><br>
+
+		In addition to supporting pan, zoom and pinch gestures, Arcball controls provide <i>focus</i> functionality with a double click/tap for
+		intuitively moving the object's point of interest in the center of the virtual trackball.   
+		Focus allows a much better inspection and navigation in complex environment. 
+		Moreover Arcball controls allow FOV manipulation (in a vertigo-style method) and z-rotation.
+		Saving and restoring of Camera State is supported also through clipboard 
+		(use ctrl+c and ctrl+v shortcuts for copy and paste the state).<br><br>
+
+		Unlike [page:OrbitControls] and [page:TrackballControls], [name] doesn't require [page:.update] to be called externally in an animation loop when animations
+		are on.<br><br>
+
+
+		To use this, as with all files in the /examples directory, you will have to
+		include the file separately in your HTML.
+

+
+		<h2>Code Example</h2>
+
+		<code>
+		const renderer = new THREE.WebGLRenderer();
+		renderer.setSize( window.innerWidth, window.innerHeight );
+		document.body.appendChild( renderer.domElement );
+
+		const scene = new THREE.Scene();
+
+		const camera = new THREE.PerspectiveCamera( 45, window.innerWidth / window.innerHeight, 1, 10000 );
+
+		const controls = new ArcballControls( camera, renderer.domElement, scene );
+
+		controls.addEventListener( 'change', function () {
+
+			renderer.render( scene, camera );
+
+		} );
+
+		//controls.update() must be called after any manual changes to the camera's transform
+		camera.position.set( 0, 20, 100 );
+		controls.update();
+		</code>

+		<h2>Examples</h2>

+
+		<h3>[name]( [param:Camera camera], [param:HTMLDOMElement domElement], [param:Scene scene] )</h3>
+		<p>
+			[page:Camera camera]: (required) The camera to be controlled. The camera must not be a child of another object, unless that object is the scene itself.<br><br>
+
+			[page:HTMLDOMElement domElement]: The HTML element used for event listeners.<br><br>
+
+			[page:Scene scene]: The scene rendered by the camera. If not given, gizmos cannot be shown.
+		</p>
+
+		<h2>Events</h2>
+
+		<h3>change</h3>
+		<p>
+			Fires when the camera has been transformed by the controls.

+		</p>
+
+		<h2>Properties</h2>
+
+		<h3>[property:Boolean adjustNearFar]</h3>
+		<p>
+			If true, camera's near and far values will be adjusted every time zoom is performed trying to mantain the same visible portion
+			given by initial near and far values ( [page:PerspectiveCamera] only ).
+			Default is false.

+		</p>
+
+		<h3>[property:HTMLDOMElement domElement]</h3>

+			not set up new event listeners.
+		</p>
+
+		<h3>[property:Boolean enabled]</h3>

+
+		<h3>[property:Boolean enableAnimations]</h3>
+		<p>
+			Set to true to enable animations for rotation (damping) and focus operation. Default is true.
+		</p>
+
+		<h3>[property:Boolean enableGrid]</h3>
+		<p>
+			When set to true, a grid will appear when panning operation is being performed (desktop interaction only). Default is false.
+		</p>
+
+		<h3>[property:Boolean enablePan]</h3>
+		<p>
+			Enable or disable camera panning. Default is true.
+		</p>
+
+		<h3>[property:Boolean enableRotate]</h3>
+		<p>
+			Enable or disable camera rotation. Default is true.
