camera-controls

A camera control for three.js, similar to THREE.OrbitControls yet supports smooth transitions and more features.

Examples

camera move	default user input (Configurable)
Orbit rotation	left mouse drag / touch: one-finger move
Dolly	middle mouse drag, or mousewheel / touch: two-finger pinch-in or out
Truck (Pan)	right mouse drag / touch: two-finger move or three-finger move

Usage

(The below code is for three.js users. If you use react-three-fiber (aka R3F), r3f-ready camera-controls is available on @react-three/drei

import * as THREE from 'three';
import CameraControls from 'camera-controls';

CameraControls.install( { THREE: THREE } );

// snip ( init three scene... )
const clock = new THREE.Clock();
const camera = new THREE.PerspectiveCamera( 60, width / height, 0.01, 1000 );
const cameraControls = new CameraControls( camera, renderer.domElement );

( function anim () {

	// snip
	const delta = clock.getDelta();
	const hasControlsUpdated = cameraControls.update( delta );

	requestAnimationFrame( anim );

	// you can skip this condition to render though
	if ( hasControlsUpdated ) {

		renderer.render( scene, camera );

	}

} )();

Important!

You must install three.js before using camera-controls. Not doing so will lead to runtime errors (undefined references to THREE).

Before creating a new CameraControls instance, call:

CameraControls.install( { THREE: THREE } );

You can then proceed to use CameraControls.

Note: If you do not wish to use the entire three.js to reduce file size(tree-shaking for example), make a subset to install.

import {
	Vector2,
	Vector3,
	Vector4,
	Quaternion,
	Matrix4,
	Spherical,
	Box3,
	Sphere,
	Raycaster,
} from 'three';

const subsetOfTHREE = {
	Vector2   : Vector2,
	Vector3   : Vector3,
	Vector4   : Vector4,
	Quaternion: Quaternion,
	Matrix4   : Matrix4,
	Spherical : Spherical,
	Box3      : Box3,
	Sphere    : Sphere,
	Raycaster : Raycaster,
};

CameraControls.install( { THREE: subsetOfTHREE } );

Constructor

CameraControls( camera, domElement )

camera is a THREE.PerspectiveCamera or THREE.OrthographicCamera to be controlled.
domElement is a HTMLElement for draggable area. (optional. if domElement is omitted here, can be connect later with .connect())

Terms

Orbit rotations

CameraControls uses Spherical Coordinates for orbit rotations.

If your camera is Y-up, the Azimuthal angle will be the angle for y-axis rotation and the Polar angle will be the angle for vertical position.

Dolly vs Zoom

A Zoom involves changing the lens focal length. In three.js, zooming is actually changing the camera FOV, and the camera is stationary (doesn't move).
A Dolly involves physically moving the camera to change the composition of the image in the frame.

See the demo

Properties

Name	Type	Default	Description
`.camera`	`THREE.Perspective \| THREE.Orthographic`	N/A	The camera to be controlled

`.minDistance`	`number`	`Number.EPSILON`	Minimum distance for dolly. The value must be higher than `0`
`.maxDistance`	`number`	`Infinity`	Maximum distance for dolly.
`.minZoom`	`number`	`0.01`	Minimum camera zoom.
`.maxZoom`	`number`	`Infinity`	Maximum camera zoom.

`.boundaryEnclosesCamera`	`boolean`	`false`	Whether camera position should be enclosed in the boundary or not.
`.smoothTime`	`number`	`0.25`	Approximate time in seconds to reach the target. A smaller value will reach the target faster.
`.draggingSmoothTime`	`number`	`0.125`	The smoothTime while dragging.
`.azimuthRotateSpeed`	`number`	`1.0`	Speed of azimuth rotation.
`.polarRotateSpeed`	`number`	`1.0`	Speed of polar rotation.
`.dollySpeed`	`number`	`1.0`	Speed of mouse-wheel dollying.
`.truckSpeed`	`number`	`2.0`	Speed of drag for truck and pedestal.
`.verticalDragToForward`	`boolean`	`false`	The same as `.screenSpacePanning` in three.js's OrbitControls.
`.dollyToCursor`	`boolean`	`false`	`true` to enable Dolly-in to the mouse cursor coords.
`.dollyDragInverted`	`boolean`	`false`	`true` to invert direction when dollying or zooming via drag.
`.interactiveArea`	`DOMRect`	N/A	Set drag-start, touches and wheel enable area in the domElement. each values are between `0` and `1` inclusive, where `0` is left/top and `1` is right/bottom of the screen.
`.colliderMeshes`	`array`	`[]`	An array of Meshes to collide with camera ².
`.infinityDolly`	`boolean`	`false`	`true` to enable Infinity Dolly for wheel and pinch. Use this with `minDistance` and `maxDistance` ³.
`.restThreshold`	`number`	`0.0025`	Controls how soon the `rest` event fires as the camera slows

Every 360 degrees turn is added to .azimuthAngle value, which is accumulative.
360º = 360 * THREE.MathUtils.DEG2RAD = Math.PI * 2, 720º = Math.PI * 4.
Tip: How to normalize accumulated azimuthAngle?
Be aware colliderMeshes may decrease performance. The collision test uses 4 raycasters from the camera since the near plane has 4 corners.
If the Dolly distance is less (or over) than the minDistance (or maxDistance), infinityDolly will keep the distance and pushes the target position instead.

Events

CameraControls instance emits the following events.
To subscribe, use cameraControl.addEventListener( 'eventname', function ).
To unsubscribe, use cameraControl.removeEventListener( 'eventname', function ).

Event name	Timing
`'controlstart'`	When the user starts to control the camera via mouse / touches. ¹
`'control'`	When the user controls the camera (dragging).
`'controlend'`	When the user ends to control the camera. ¹
`'transitionstart'`	When any kind of transition starts, either user control or using a method with `enableTransition = true`
`'update'`	When the camera position is updated.
`'wake'`	When the camera starts moving.
`'rest'`	When the camera movement is below `.restThreshold` ².
`'sleep'`	When the camera end moving.

mouseButtons.wheel (Mouse wheel control) does not emit 'controlstart' and 'controlend'. mouseButtons.wheel uses scroll-event internally, and scroll-event happens intermittently. That means "start" and "end" cannot be detected.
Due to damping, sleep will usually fire a few seconds after the camera appears to have stopped moving. If you want to do something (e.g. enable UI, perform another transition) at the point when the camera has stopped, you probably want the rest event. This can be fine tuned using the .restThreshold parameter. See the Rest and Sleep Example.

Tips

Normalize accumulated azimuth angle:

If you need a normalized accumulated azimuth angle (between 0 and 360 deg), compute with THREE.MathUtils.euclideanModulo e.g.:

const TAU = Math.PI * 2;

function normalizeAngle( angle ) {

	return THREE.MathUtils.euclideanModulo( angle, TAU );

}

const normalizedAzimuthAngle = normalizeAngle( cameraControls.azimuthAngle );

Find the absolute angle to shortest azimuth rotatation:

You may rotate 380deg but actually, you expect to rotate -20deg.
To get the absolute angle, use the below:

const TAU = Math.PI * 2;

function absoluteAngle( targetAngle, sourceAngle ){

  const angle = targetAngle - sourceAngle
  return THREE.MathUtils.euclideanModulo( angle + Math.PI, TAU ) - Math.PI;

}

console.log( absoluteAngle( 380 * THREE.MathUtils.DEG2RAD, 0 ) * THREE.MathUtils.RAD2DEG ); // -20deg
console.log( absoluteAngle( -1000 * THREE.MathUtils.DEG2RAD, 0 ) * THREE.MathUtils.RAD2DEG ); // 80deg

Creating Complex Transitions

All methods that take the enableTransition parameter return a Promise can be used to create complex animations, for example:

async function complexTransition() {
	await cameraControls.rotateTo( Math.PI / 2, Math.PI / 4, true );
	await cameraControls.dollyTo( 3, true );
	await cameraControls.fitToSphere( mesh, true );
}

This will rotate the camera, then dolly, and finally fit to the bounding sphere of the mesh.

The speed and timing of transitions can be tuned using .restThreshold and .smoothTime.

If enableTransition is false, the promise will resolve immediately:

// will resolve immediately
await cameraControls.dollyTo( 3, false );

V2 Migration Guide

camera-controls used to use simple damping for its smooth transition. camera-controls v2 now uses SmoothDamp. one of the benefits of using SmoothDamp is, SmoothDamp transition can be controlled with smoothTime which is approximately the time it will take to reach the end position. Also, the Maximum speed of the transition can be set with max speed.

Due to the change, the following are needed. (if you haven't changed dampingFactor and draggingDampingFactor in v1.x, nothing is needed)

deprecated

dampingFactor (use smoothTime instead)
draggingDampingFactor (use draggingSmoothTime instead)

added

smoothTime
draggingSmoothTime
maxSpeed

...That's it!
