animations: Animation[] = []

Gets a list of Animations associated with the node

applyGravity: boolean = false

Enable or disable gravity on the camera.

cameraDirection: Vector3 = ...

Define the current direction the camera is moving to

cameraRigMode: number = Camera.RIG_MODE_NONE

Rig mode of the camera. This is useful to create the camera with two "eyes" instead of one to create VR or stereoscopic scenes. This is normally controlled byt the camera themselves as internal use.

cameraRotation: Vector2 = ...

Define the current rotation the camera is rotating to

checkCollisions: boolean = false

Enable or disable collisions of the camera with the rest of the scene objects.

customRenderTargets: RenderTargetTexture[] = []

Defines the list of custom render target which are rendered to and then used as the input to this camera's render. Eg. display another camera view on a TV in the main scene This is pretty helpful if you wish to make a camera render to a texture you could reuse somewhere else in the scene. (Eg. security camera)

To change the final output target of the camera, camera.outputRenderTarget should be used instead (eg. webXR renders to a render target corresponding to an HMD)

ellipsoid: Vector3 = ...

Define the collision ellipsoid of the camera. This is helpful to simulate a camera body like the player body around the camera

https://doc.babylonjs.com/features/featuresDeepDive/cameras/camera_collisions#arcrotatecamera

ellipsoidOffset: Vector3 = ...

Define an offset for the position of the ellipsoid around the camera. This can be helpful to determine the center of the body near the gravity center of the body instead of its head.

fov: number = 0.8

Field Of View is set in Radians. (default is 0.8)

fovMode: number = Camera.FOVMODE_VERTICAL_FIXED

fovMode sets the camera frustum bounds to the viewport bounds. (default is FOVMODE_VERTICAL_FIXED)

id: string

Gets or sets the id of the node

ignoreCameraMaxZ: boolean = false

Ignores camera maxZ when computing the projection matrix (ie. use 0 instead of maxZ), meaning objects won't be culled by the far plane

inputs: FreeCameraInputsManager

Define the input manager associated to the camera.

inspectableCustomProperties: IInspectable[]

List of inspectable custom properties (used by the Inspector)

https://doc.babylonjs.com/toolsAndResources/inspector#extensibility

interaxialDistance: number

Defines the distance between both "eyes" in case of a RIG

inverseRotationSpeed: number = 0.2

Speed multiplier for inverse camera panning

invertRotation: boolean = false

Reverses mouselook direction to 'natural' panning as opposed to traditional direct panning

isIntermediate: boolean = false

Define whether the camera is intermediate. This is useful to not present the output directly to the screen in case of rig without post process for instance

isRigCamera: boolean = false

Is this camera a part of a rig system?

isStereoscopicSideBySide: boolean

Defines if stereoscopic rendering is done side by side or over under.

layerMask: number = 0x0fffffff

Restricts the camera to viewing objects with the same layerMask. A camera with a layerMask of 1 will render mesh.layerMask & camera.layerMask!== 0

lockedTarget: any = null

Define the current target of the camera as an object or a position. Please note that locking a target will disable panning.

maxZ: number = 10000.0

Define the maximum distance the camera can see to. (default is 10000) This is important to note that the depth buffer are not infinite and the further it end the more your scene might encounter depth fighting issue.

metadata: any = null

Gets or sets an object used to store user defined information for the node

minZ: number = 1

Define the minimum distance the camera can see from. This is important to note that the depth buffer are not infinite and the closer it starts the more your scene might encounter depth fighting issue.

movement: TargetCameraMovement

Framerate-independent movement controller for the free camera, exposing the configurable InputMapper (movement.input) consulted by the free-camera input classes. Narrows the inherited TargetCamera.movement to TargetCameraMovement; the instance is created by the TargetCamera constructor.

name: string

Gets or sets the name of the node

noRotationConstraint: boolean = false

Add constraint to the camera to prevent it to move freely in all directions and around all axis.

oblique: Nullable<IObliqueParams> = null

Object containing oblique projection values (only used with ORTHOGRAPHIC_CAMERA)

onAccessibilityTagChangedObservable: Observable<Nullable<IAccessibilityTag>> = ...

Observable fired when an accessibility tag is changed

onAfterCheckInputsObservable: Observable<Camera> = ...

Observable triggered when the inputs have been processed.

onCollide: (collidedMesh: AbstractMesh) => void

Event raised when the camera collide with a mesh in the scene.

onDisposeObservable: Observable<Node> = ...

An event triggered when the mesh is disposed

onProjectionMatrixChangedObservable: Observable<Camera> = ...

Observable triggered when the camera Projection matrix has changed.

onReady: Nullable<(node: Node) => void> = null

Callback raised when the node is ready to be used

onRestoreStateObservable: Observable<Camera> = ...

Observable triggered when reset has been called and applied to the camera.

onViewMatrixChangedObservable: Observable<Camera> = ...

Observable triggered when the camera view matrix has changed. Beware of reentrance! Some methods like Camera.getViewMatrix and Camera.getWorldMatrix can trigger the onViewMatrixChangedObservable observable, so using them inside an observer will require additional logic to avoid a stack overflow error.

outputRenderTarget: Nullable<RenderTargetTexture> = null

When set, the camera will render to this render target instead of the default canvas

If the desire is to use the output of a camera as a texture in the scene consider using camera.customRenderTargets instead

projectionPlaneTilt: number = 0

Projection plane tilt around the X axis (horizontal), set in Radians. (default is 0) Can be used to make vertical lines in world space actually vertical on the screen. See https://forum.babylonjs.com/t/add-vertical-shift-to-3ds-max-exporter-babylon-cameras/17480

This setting aligns the left and right bounds of the viewport to the left and right bounds of the camera frustum.

FOVMODE_VERTICAL_FIXED: 0 = Constants.FOVMODE_VERTICAL_FIXED

This is the default FOV mode for perspective cameras. This setting aligns the upper and lower bounds of the viewport to the upper and lower bounds of the camera frustum.

ORTHOGRAPHIC_CAMERA: 1 = Constants.ORTHOGRAPHIC_CAMERA

This helps creating camera with an orthographic mode. Orthographic is commonly used in engineering as a means to produce object specifications that communicate dimensions unambiguously, each line of 1 unit length (cm, meter..whatever) will appear to have the same length everywhere on the drawing. This allows the drafter to dimension only a subset of lines and let the reader know that other lines of that length on the drawing are also that length in reality. Every parallel line in the drawing is also parallel in the object.

PERSPECTIVE_CAMERA: 0 = Constants.PERSPECTIVE_CAMERA

This is the default projection mode used by the cameras. It helps recreating a feeling of perspective and better appreciate depth. This is the best way to simulate real life cameras.

RIG_MODE_CUSTOM: 22 = Constants.RIG_MODE_CUSTOM

Custom rig mode allowing rig cameras to be populated manually with any number of cameras

RIG_MODE_NONE: 0 = Constants.RIG_MODE_NONE

This specifies there is no need for a camera rig. Basically only one eye is rendered corresponding to the camera.

RIG_MODE_STEREOSCOPIC_ANAGLYPH: 10 = Constants.RIG_MODE_STEREOSCOPIC_ANAGLYPH

Simulates a camera Rig with one blue eye and one red eye. This can be use with 3d blue and red glasses.

RIG_MODE_STEREOSCOPIC_INTERLACED: 14 = Constants.RIG_MODE_STEREOSCOPIC_INTERLACED

Defines that both eyes of the camera will be rendered on successive lines interlaced for passive 3d monitors.

RIG_MODE_STEREOSCOPIC_OVERUNDER: 13 = Constants.RIG_MODE_STEREOSCOPIC_OVERUNDER

Defines that both eyes of the camera will be rendered over under each other.

RIG_MODE_STEREOSCOPIC_SIDEBYSIDE_CROSSEYED: 12 = Constants.RIG_MODE_STEREOSCOPIC_SIDEBYSIDE_CROSSEYED

Defines that both eyes of the camera will be rendered side by side with a none parallel target.

RIG_MODE_STEREOSCOPIC_SIDEBYSIDE_PARALLEL: 11 = Constants.RIG_MODE_STEREOSCOPIC_SIDEBYSIDE_PARALLEL

Defines that both eyes of the camera will be rendered side by side with a parallel target.

RIG_MODE_VR: 20 = Constants.RIG_MODE_VR

Defines that both eyes of the camera should be renderered in a VR mode (carbox).

  • get angularSensibility(): number

    Gets the input sensibility for a mouse input. (default is 2000.0) Higher values reduce sensitivity.

    Returns number

  • set angularSensibility(value: number): void

    Sets the input sensibility for a mouse input. (default is 2000.0) Higher values reduce sensitivity.

    Parameters

    • value: number

    Returns void

  • get doNotSerialize(): boolean

    Gets or sets a boolean used to define if the node must be serialized

    Returns boolean

  • set doNotSerialize(value: boolean): void

    Parameters

    • value: boolean

    Returns void

  • get inertia(): number

    Defines the inertia (decay coefficient applied per reference frame at 60fps) of the camera. This helps giving a smooth feeling to the camera movement.

    Override of Camera.inertia that writes through to the movement system so the framerate-independent pan/rotation glide stays in sync. Setting this updates the movement system immediately (matching the accessor convergence used by ArcRotateCamera).

    Backed by a local field rather than super.inertia: the shipped UMD bundle is compiled with TypeScript at target: ES5, and ES5 downleveling of super access inside a decorated accessor (the base Camera.inertia carries @serialize()) mis-compiles to undefined. That would feed NaN into the movement decay and freeze the camera. It only breaks in the ES5 UMD bundle; native-ESM dev keeps real super. See the babylonjs/no-super-in-accessor lint rule.

    Returns number

  • set inertia(value: number): void

    Define the default inertia of the camera. This helps giving a smooth feeling to the camera movement.

    Parameters

    • value: number

    Returns void

  • get inheritVisibility(): boolean

    If set to true, this node, when renderable, will only be visible if its parent(s) are also visible.

    Returns boolean

    false
  • set inheritVisibility(value: boolean): void

    Parameters

    • value: boolean

    Returns void

  • get isVisible(): boolean

    Gets or sets a boolean indicating whether this node is visible, either this node itself when it is renderable or its renderable child nodes when inheritVisibility is true.

    Returns boolean

    true
  • set isVisible(value: boolean): void

    Parameters

    • value: boolean

    Returns void

  • set onDispose(callback: () => void): void

    Sets a callback that will be raised when the node will be disposed

    Parameters

    • callback: () => void

    Returns void

  • get onEffectiveEnabledStateChangedObservable(): Observable<boolean>

    An event triggered when the effective enabled state of the node changes, i.e. whenever the value returned by isEnabled changes. Unlike onEnabledStateChangedObservable, this fires for changes caused by an ancestor's enabled state as well as this node's own state. The observable is created on first access, so no cost is incurred for nodes that never observe it.

    Returns Observable<boolean>

  • get worldMatrixFromCache(): Matrix

    Returns directly the latest state of the mesh World matrix. A Matrix is returned.
