    behaviors: Behavior[] = []
    bounds: BoundingVolume | undefined = undefined

    The physical bounding volume of the object.

    castShadow: boolean

    Whether the light casts shadows.

    children: Object3D[] = []
    color: Color

    The color of the light.

    frustumCulled: boolean = true
    geometry: GeometryDataInterface | undefined = undefined
    inFrustum: boolean = true
    intensity: number

    The intensity of the light.

    isCollidable: boolean = true

    Whether this object should generate bounds and participate in physics/raycasting. Defaults to true.

    isPickable: boolean = false
    isStatic: boolean = false
    isVisible: boolean = true
    localMatrix: Matrix4 = ...

    receiveShadow: boolean = false
    rigidBody?: RigidBody
    rotation: Vector3D = ...
    scale: Vector3D = ...
    shadowBias: number

    A small offset to prevent shadow acne.

    shadowCamera: Camera | undefined

    The camera used to render the shadow map for this light.

    shadowNormalBias: number

    An offset along the surface normal to prevent shadow acne.

    shadowResolution: number

    The resolution of the shadow map for this light.

    tag?: string

    Optional app-defined category tag, for typed identification instead of matching on name.

    type: LightType

    The type of the light.

    uuid: string = ...
    worldMatrix: Matrix4 = ...

    • Reads this object's position in world space, i.e. after resolving the full parent chain -- unlike position, which is always local to its immediate parent. Requires worldMatrix to be current (see updateMatrixWorld()).

      Parameters

      • out: Vector3D = ...

        Optional vector to write into, to avoid allocating one per call.

      Returns Vector3D
