# [name]

Orbit controls allow the camera to orbit around a target.
To use this, as with all files in the /examples directory, you will have to include the file separately in your HTML.

## Import

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

`import { OrbitControls } from 'three/addons/controls/OrbitControls.js';`

## Code Example

`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 OrbitControls( camera, renderer.domElement ); //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 ); }`

## Constructor

### [name]( [param:Camera object], [param:HTMLDOMElement domElement] )

[page:Camera object]: (required) The camera to be controlled. The camera must not be a child of another object, unless that object is the scene itself.
[page:HTMLDOMElement domElement]: The HTML element used for event listeners.

## Events

### change

Fires when the camera has been transformed by the controls.

### start

Fires when an interaction was initiated.

### end

Fires when an interaction has finished.

## Properties

### [property:Boolean autoRotate]

Set to true to automatically rotate around the target.
Note that if this is enabled, you must call [page:.update] () in your animation loop. If you want the auto-rotate speed to be independent of the frame rate (the refresh rate of the display), you must pass the time `deltaTime`, in seconds, to [page:.update]().

### [property:Float autoRotateSpeed]

How fast to rotate around the target if [page:.autoRotate] is true. Default is 2.0, which equates to 30 seconds per orbit at 60fps.
Note that if [page:.autoRotate] is enabled, you must call [page:.update] () in your animation loop.

### [property:Float dampingFactor]

The damping inertia used if [page:.enableDamping] is set to `true`. Default is `0.05`.
Note that for this to work, you must call [page:.update] () in your animation loop.

### [property:HTMLDOMElement domElement]

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.

### [property:Boolean enabled]

When set to `false`, the controls will not respond to user input. Default is `true`.

### [property:Boolean enableDamping]

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

### [property:Boolean enablePan]

Enable or disable camera panning. Default is true.

### [property:Boolean enableRotate]

Enable or disable horizontal and vertical rotation of the camera. Default is true.
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.

### [property:Boolean enableZoom]

Enable or disable zooming (dollying) of the camera.

### [property:Float keyPanSpeed]

How fast to pan the camera when the keyboard is used. Default is 7.0 pixels per keypress.

### [property:Object keys]

This object contains references to the keycodes for controlling camera panning. Default is the 4 arrow keys. `controls.keys = { LEFT: 'ArrowLeft', //left arrow UP: 'ArrowUp', // up arrow RIGHT: 'ArrowRight', // right arrow BOTTOM: 'ArrowDown' // down arrow }` See [link:https://developer.mozilla.org/en-US/docs/Web/API/KeyboardEvent/code KeyboardEvent.code] for a full list of keycodes.

### [property:Float maxAzimuthAngle]

How far you can orbit horizontally, upper limit. If set, the interval [ min, max ] must be a sub-interval of [ - 2 PI, 2 PI ], with ( max - min < 2 PI ). Default is Infinity.

### [property:Float maxDistance]

How far you can dolly out ( [page:PerspectiveCamera] only ). Default is Infinity.

### [property:Float maxPolarAngle]

How far you can orbit vertically, upper limit. Range is 0 to Math.PI radians, and default is Math.PI.

### [property:Float maxZoom]

How far you can zoom out ( [page:OrthographicCamera] only ). Default is Infinity.

### [property:Float minTargetRadius]

How close you can get the target to the 3D [page:.cursor]. Default is 0.

### [property:Float maxTargetRadius]

How far you can move the target from the 3D [page:.cursor]. Default is Infinity.

### [property:Float minAzimuthAngle]

How far you can orbit horizontally, lower limit. If set, the interval [ min, max ] must be a sub-interval of [ - 2 PI, 2 PI ], with ( max - min < 2 PI ). Default is Infinity.

### [property:Float minDistance]

How far you can dolly in ( [page:PerspectiveCamera] only ). Default is 0.

### [property:Float minPolarAngle]

How far you can orbit vertically, lower limit. Range is 0 to Math.PI radians, and default is 0.

### [property:Float minZoom]

How far you can zoom in ( [page:OrthographicCamera] only ). Default is 0.

### [property:Object mouseButtons]

This object contains references to the mouse actions used by the controls. `controls.mouseButtons = { LEFT: THREE.MOUSE.ROTATE, MIDDLE: THREE.MOUSE.DOLLY, RIGHT: THREE.MOUSE.PAN }`

### [property:Camera object]

The camera being controlled.

### [property:Float panSpeed]

Speed of panning. Default is 1.

### [property:Vector3 position0]

Used internally by the [page:.saveState] and [page:.reset] methods.

### [property:Float rotateSpeed]

Speed of rotation. Default is 1.

### [property:Boolean screenSpacePanning]

Defines how the camera's position is translated when panning. If true, the camera pans in screen space. Otherwise, the camera pans in the plane orthogonal to the camera's up direction. Default is `true`.

### [property:Vector3 target0]

Used internally by the [page:.saveState] and [page:.reset] methods.

### [property:Vector3 target]

The focus point of the controls, the [page:.object] orbits around this. It can be updated manually at any point to change the focus of the controls.

### [property:Vector3 cursor]

The focus point of the [page:.minTargetRadius] and [page:.maxTargetRadius] limits. It can be updated manually at any point to change the center of interest for the [page:.target].

### [property:Object touches]

This object contains references to the touch actions used by the controls. `controls.touches = { ONE: THREE.TOUCH.ROTATE, TWO: THREE.TOUCH.DOLLY_PAN }`

### [property:Float zoom0]

Used internally by the [page:.saveState] and [page:.reset] methods.

### [property:Float zoomSpeed]

Speed of zooming / dollying. Default is 1.

### [property:Boolean zoomToCursor]

Setting this property to `true` allows to zoom to the cursor's position. Default is `false`.

## Methods

### [method:undefined dispose] ()

Remove all the event listeners.

### [method:radians getAzimuthalAngle] ()

Get the current horizontal rotation, in radians.

### [method:radians getPolarAngle] ()

Get the current vertical rotation, in radians.

### [method:Float getDistance] ()

Returns the distance from the camera to the target.

### [method:undefined listenToKeyEvents] ( [param:HTMLDOMElement domElement] )

Adds key event listeners to the given DOM element. `window` is a recommended argument for using this method.

### [method:undefined reset] ()

Reset the controls to their state from either the last time the [page:.saveState] was called, or the initial state.

### [method:undefined saveState] ()

Save the current state of the controls. This can later be recovered with [page:.reset].

### [method:undefined stopListenToKeyEvents] ()

Removes the key event listener previously defined with [page:.listenToKeyEvents]().

### [method:Boolean update] ( [param:Number deltaTime] )

Update the controls. Must be called after any manual changes to the camera's transform, or in the update loop if [page:.autoRotate] or [page:.enableDamping] are set. `deltaTime`, in seconds, is optional, and is only required if you want the auto-rotate speed to be independent of the frame rate (the refresh rate of the display).
