		<h1>[name]</h1>

		<p class="desc">
			This class can be used to provide a drag'n'drop interaction.
		</p>

		<h2>Import</h2>

		<p>
			[name] is an add-on, and must be imported explicitly.
			See [link:#manual/introduction/Installation Installation / Addons].
		</p>

		<code>
			import { DragControls } from 'three/addons/controls/DragControls.js';
		</code>

		<h2>Code Example</h2>

		<code>
		const controls = new DragControls( objects, camera, renderer.domElement );

		// add event listener to highlight dragged objects

		controls.addEventListener( 'dragstart', function ( event ) {

			event.object.material.emissive.set( 0xaaaaaa );

		} );

		controls.addEventListener( 'dragend', function ( event ) {

			event.object.material.emissive.set( 0x000000 );

		} );
		</code>

		<h2>Examples</h2>

		<p>[example:misc_controls_drag misc / controls / drag ]</p>

		<h2>Constructor</h2>

		<h3>[name]( [param:Array objects], [param:Camera camera], [param:HTMLDOMElement domElement] )</h3>
			<p>
				[page:Array objects]: An array of draggable 3D objects.
			</p>
			<p>
			[page:Camera camera]: The camera of the rendered scene.
			</p>
			<p>
			[page:HTMLDOMElement domElement]: The HTML element used for event listeners.
			</p>
			<p>
				Creates a new instance of [name].
			</p>

		<h2>Events</h2>

		<h3>dragstart</h3>
		<p>
			Fires when the user starts to drag a 3D object.
		</p>

		<h3>drag</h3>
		<p>
			Fires when the user drags a 3D object.
		</p>

		<h3>dragend</h3>
		<p>
			Fires when the user has finished dragging a 3D object.
		</p>

		<h3>hoveron</h3>
		<p>
			Fires when the pointer is moved onto a 3D object, or onto one of its children.
		</p>

		<h3>hoveroff</h3>
		<p>
			Fires when the pointer is moved out of a 3D object.
		</p>

		<h2>Properties</h2>

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

		<h3>[property:Boolean recursive]</h3>
		<p>
			Whether children of draggable objects can be dragged independently from their parent. Default is `true`.
		</p>

		<h3>[property:Boolean transformGroup]</h3>
		<p>
			This option only works if the [page:DragControls.objects] array contains a single draggable group object.
			If set to `true`, [name] does not transform individual objects but the entire group. Default is `false`.
		</p>

		<h3>[property:String mode]</h3>
		<p>
			The current transformation mode. Possible values are `translate`, and `rotate`. Default is `translate`.
		</p>

		<h3>[property:Float rotateSpeed]</h3>
		<p>
			The speed at which the object will rotate when dragged in `rotate` mode. The higher the number the faster the rotation. Default is `1`.
		</p>

		<h2>Methods</h2>

		<p>See the base [page:EventDispatcher] class for common methods.</p>

		<h3>[method:undefined activate] ()</h3>
		<p>
			Adds the event listeners of the controls.
		</p>

		<h3>[method:undefined deactivate] ()</h3>
		<p>
			Removes the event listeners of the controls.
		</p>

		<h3>[method:undefined dispose] ()</h3>
		<p>
			Should be called if the controls is no longer required.
		</p>

		<h3>[method:Array getObjects] ()</h3>
		<p>
			Returns the array of draggable objects.
		</p>

		<h3>[method:Raycaster getRaycaster] ()</h3>
		<p>
			Returns the internal [page:Raycaster] instance that is used for intersection tests.
		</p>

		<h3>[method:undefined setObjects] ( [param:Array objects] )</h3>
		<p>
			Sets an array of draggable objects by overwriting the existing one.
		</p>
