Class: DefaultCameraManager

Default implementation of CameraManager. Uses target-based orbit controls combined with keyboard and mouse navigation possibility. Supports automatic update of camera near and far planes and animated change of camera position and target.

Implements

Properties

automaticControlsSensitivity

automaticControlsSensitivity: boolean = true

When false, the sensitivity of the camera controls will not be updated automatically. This can be useful to better control the sensitivity of the 3D navigation.

When not set, control the sensitivity of the camera using viewer.cameraManager.cameraControls.minDistance and viewer.cameraManager.cameraControls.maxDistance.

packages/camera-manager/src/DefaultCameraManager.ts:108


automaticNearFarPlane

automaticNearFarPlane: boolean = true

When false, camera near and far planes will not be updated automatically (defaults to true). This can be useful when you have custom content in the 3D view and need to better control the view frustum.

When automatic camera near/far planes are disabled, you are responsible for setting this on your own.

Example

viewer.camera.near = 0.1;
viewer.camera.far = 1000.0;
viewer.camera.updateProjectionMatrix();

Accessors

keyboardNavigationEnabled

get keyboardNavigationEnabled(): boolean

Whether keyboard control of the camera is enabled/disabled.

set keyboardNavigationEnabled(enabled): void

Sets whether keyboard control of the camera is enabled/disabled.

Parameters

enabled: boolean

Returns

boolean

packages/camera-manager/src/DefaultCameraManager.ts:194

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

Implementation of

CameraManager . activate

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:237


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

Implementation of

CameraManager . deactivate

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:251


dispose()

dispose(): void

Returns

void

Implementation of

CameraManager . dispose

Obvious

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:289


fitCameraToBoundingBox()

fitCameraToBoundingBox(box, duration?, radiusFactor?): void

Moves camera to a place where the content of a bounding box is visible to the camera.

Parameters

box: Box3

The bounding box in world space.

duration?: number

The duration of the animation moving the camera.

radiusFactor?: number = 2

The ratio of the distance from camera to center of box and radius of the box.

Returns

void

Implementation of

CameraManager . fitCameraToBoundingBox

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:164


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

Implementation of

CameraManager . getCamera

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:198


getCameraControlsOptions()

getCameraControlsOptions(): CameraControlsOptions

Gets current camera controls options.

Returns

CameraControlsOptions

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:262


getCameraState()

getCameraState(): Required <CameraState>

Get camera's state

Returns

Required <CameraState>

Camera state: position, target and rotation.

Implementation of

CameraManager . getCameraState

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:229


getComboControlsOptions()

getComboControlsOptions(): Readonly <ComboControlsOptions>

Gets current Combo Controls options.

Returns

Readonly <ComboControlsOptions>

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:172


off()

off(event, callback): void

Unsubscribes from changes of the camera event.

Parameters

event: "cameraChange" | "cameraStop"

The event type.

callback: CameraEventDelegate

Callback function to be unsubscribed.

Returns

void

Implementation of

CameraManager . off

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:151


on()

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" | "cameraStop"

The event type.

callback: CameraEventDelegate

Callback to be called when the event is fired.

Returns

void

Implementation of

CameraManager . on

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:138


setCameraControlsOptions()

setCameraControlsOptions(controlsOptions): void

Sets camera controls options to customize camera controls modes. See CameraControlsOptions.

Parameters

controlsOptions: CameraControlsOptions

JSON object with camera controls options.

Returns

void

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:270


setCameraState()

setCameraState(state): void

Sets camera state. All parameters are optional. Rotation and target can't be set at the same time, if so, error will be thrown. Set rotation is preserved until next call of setCameraState with empty rotation field.

Parameters

state: CameraState

Camera state. *

Returns

void

Implementation of

CameraManager . setCameraState

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:208


setComboControlsOptions()

setComboControlsOptions(options): void

Sets Combo Controls options. Only provided options will be changed, any undefined options will be kept as is.

Parameters

options: Partial <ComboControlsOptions>

Returns

void

Defined in

packages/camera-manager/src/DefaultCameraManager.ts:180


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

Implementation of

CameraManager . update
