Interface: CameraManager
Interface for manager responsible for all manipulations to the camera,
including animations and modification of state. Implementations are responsible for
providing a THREE.PerspectiveCamera instance to the viewer. Implementations
must trigger the cameraChange-event when camera is changed.
The default implementation is DefaultCameraManager.

Methods
activate()
activate(
cameraManager?):void
Set this manager as active and enable controls.
Should update CameraManager.enabled to reflect the state of the manager. Note that this is called automatically when a new CameraManager is set on the viewer.
Parameters
• cameraManager?: CameraManager
Previously used camera manager.
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:61
deactivate()
deactivate():
void
Deactivate this manager and disable controls.
Should update CameraManager.enabled to reflect the state of the manager. Note that this is called automatically when a new CameraManager is set on the viewer.
Returns
void

dispose():
void
Returns

fitCameraToBoundingBox()
fitCameraToBoundingBox(
boundingBox,duration?,radiusFactor?):void
Moves camera to a place where the content of a bounding box is visible to the camera.
Parameters
• boundingBox: Box3
The bounding box in world space.
• duration?: number
The duration of the animation moving the camera.
• radiusFactor?: number
The ratio of the distance from camera to center of box and radius of the box.
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:97
getCamera()
getCamera():
PerspectiveCamera
Returns the camera used for rendering the viewer.
Note that the camera will not be modified directly by Reveal.
Implementations must trigger the cameraChange-event whenever the
camera changes.
Returns
PerspectiveCamera
Defined in
packages/camera-manager/src/CameraManager.ts:29
getCameraState()
getCameraState():
Required<CameraState>
Get camera's state
Returns
Required<CameraState>
Camera state: position, target and rotation.
Defined in
packages/camera-manager/src/CameraManager.ts:52
off()
off(event, callback)
off(
event,callback):void
Unsubscribes from changes of the camera event.
Parameters
• event: "cameraChange"
The event type.
• callback: CameraChangeDelegate
Callback function to be unsubscribed.
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:87
off(event, callback)
off(
event,callback):void
Parameters
• event: "cameraStop"
• callback: CameraStopDelegate
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:88
off(event, callback)
off(
event,callback):void
Parameters
• event: "cameraChange" | "cameraStop"
• callback: CameraEventDelegate
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:89
on()
on(event, callback)
on(
event,callback):void
Subscribes to events on this camera manager. There are several event types: 'cameraChange' - Subscribes to changes of the camera. This is used by Reveal to react on changes of the camera. 'cameraStop' - Subscribes to events indicating the camera has stopped
Parameters
• event: "cameraChange"
The event type.
• callback: CameraChangeDelegate
Callback to be called when the event is fired.
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:78
on(event, callback)
on(
event,callback):void
Parameters
• event: "cameraStop"
• callback: CameraStopDelegate
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:79
on(event, callback)
on(
event,callback):void
Parameters
• event: "cameraChange" | "cameraStop"
• callback: CameraEventDelegate
Returns
void
Defined in
packages/camera-manager/src/CameraManager.ts:80
setCameraState()
setCameraState(
state):void
Set camera's state. Rotation and target can't be set at the same time as they could conflict, should throw an error if both are passed with non-zero value inside state.
Parameters
• state: CameraState
Camera state, all fields are optional.
Returns
void
Example
// store position, target
const { position, target } = cameraManager.getCameraState();
// restore position, target
cameraManager.setCameraState({ position, target });
Defined in
packages/camera-manager/src/CameraManager.ts:46
update()
update(
deltaTime,boundingBox):void
Updates internal state of camera manager. Expected to update visual state of the camera
as well as it's near and far planes if needed. Called in requestAnimationFrame-loop.
Reveal performance affects frequency with which this method is called.
Parameters
• deltaTime: number
Delta time since last update in seconds.
• boundingBox: Box3
Global bounding box of the model(s) and any custom objects added to the scene.
Returns
void
