Properties

assetType

assetType: "light" = ...

castShadow

castShadow: boolean

If set to true light will cast dynamic shadows. Warning: This is expensive and requires tweaking to get shadows looking right.

See

PointLightShadow for details.

Default Value

false

children

children: IObject3D[]

Array with object's children.

See

THREE.Object3DGroup | Group for info on manually grouping objects.

Default Value

[]

clone

clone: (recursive?: boolean) => this

Returns a clone of this object and optionally all descendants.

Type declaration

    • (recursive?: boolean): this

    • Parameters

      • Optionalrecursive: boolean

        If true, descendants of the object are also cloned. Default true

      Returns this

color

color: Color

Color of the light. \

Default Value

new THREE.Color(0xffffff) (white).

copy

copy: (
    source: IObject3D | PointLight,
    recursive?: boolean,
    ...args: any[],
) => this

Copies value of all the properties from the source to this instance.

decay

decay: number

The amount the light dims along the distance of the light. In context of physically-correct rendering the default value should not be changed.

Remarks

Expects a Float

Default Value

2

dispatchEvent

dispatchEvent: (event: ILightEvent) => void

Fire an event type.

Type declaration

distance

distance: number

When Default mode — When distance is zero, light does not attenuate. When distance is non-zero, light will attenuate linearly from maximum intensity at the light's position down to zero at this distance from the light.

When WebGLRenderer.useLegacyLights | legacy lighting mode is disabled — When distance is zero, light will attenuate according to inverse-square law to infinite distance. When distance is non-zero, light will attenuate according to inverse-square law until near the distance cutoff, where it will then attenuate quickly and smoothly to 0. Inherently, cutoffs are not physically correct.

Default Value

0.0

Remarks

Expects a Float

getObjectById

getObjectById: <T extends IObject3D = IObject3D>(id: number) => undefined | T

Searches through an object and its children, starting with the object itself, and returns the first with a matching id.

Type declaration

    • <T extends IObject3D = IObject3D>(id: number): undefined | T

    • Type Parameters

      Parameters

      • id: number

        Unique number of the object instance. Expects a Integer

      Returns undefined | T

Remarks

Note that ids are assigned in chronological order: 1, 2, 3, ..., incrementing by one for each new object.

See

id

getObjectByName

getObjectByName: <T extends IObject3D = IObject3D>(
    name: string,
) => undefined | T

Searches through an object and its children, starting with the object itself, and returns the first with a matching name.

Type declaration

Remarks

Note that for most objects the name is an empty string by default

getObjectByProperty

getObjectByProperty: <T extends IObject3D = IObject3D>(
    name: string,
    value: string,
) => undefined | T

Searches through an object and its children, starting with the object itself, and returns the first with a property that matches the value given.

Type declaration

    • <T extends IObject3D = IObject3D>(name: string, value: string): undefined | T

    • Type Parameters

      Parameters

      • name: string

        the property name to search for.

      • value: string

        value of the given property.

      Returns undefined | T

intensity

intensity: number

The light's intensity.

When WebGLRenderer.useLegacyLights | legacy lighting mode is disabled — intensity is the luminous intensity of the light measured in candela (cd).

Remarks

Changing the intensity will also change the light's power.

Default Value

1

ReadonlyisPointLight2

isPointLight2: true

parent

parent: null | IObject3D

Object's parent in the scene graph.

Remarks

An object can have at most one parent.

Default Value

null

Readonlyposition

position: Vector3

Object's local position.

Default Value

new THREE.Vector3() - that is (0, 0, 0).

power

power: number

The light's power. When WebGLRenderer.useLegacyLights | legacy lighting mode is disabled — power is the luminous power of the light measured in lumens (lm).

Remarks

Changing the power will also change the light's intensity.

refreshUi

refreshUi: (this: IObject3D) => void = iLightCommons.refreshUi

remove

remove: (...object: IObject3D[]) => this

Removes a Object3D as child of this Object3D.

Remarks

An arbitrary number of objects may be removed.

See

Group for info on manually grouping objects.

setDirty

setDirty: (
    this: ILight,
    options?: IObjectSetDirtyOptions,
    ...args: any[],
) => void = iLightCommons.setDirty

Dispatches 'objectUpdate' event on object.

shadowAspect

shadowAspect: number

shadowBias

shadowBias: number

shadowFar

shadowFar: number

shadowFov

shadowFov: number

shadowMapSize

shadowMapSize: Vector2

shadowNear

shadowNear: number

shadowRadius

shadowRadius: number

traverse

traverse: (callback: (object: IObject3D) => void) => void

Executes the callback on this object and all descendants.

Type declaration

    • (callback: (object: IObject3D) => void): void

    • Parameters

      • callback: (object: IObject3D) => void

        A function with as first argument an Object3D object.

      Returns void

Remarks

Note: Modifying the scene graph inside the callback is discouraged.

traverseAncestors

traverseAncestors: (callback: (object: IObject3D) => void) => void

Executes the callback on all ancestors.

Type declaration

    • (callback: (object: IObject3D) => void): void

    • Parameters

      • callback: (object: IObject3D) => void

        A function with as first argument an Object3D object.

      Returns void

Remarks

Note: Modifying the scene graph inside the callback is discouraged.

traverseVisible

traverseVisible: (callback: (object: IObject3D) => void) => void

Like traverse, but the callback will only be executed for visible objects

Type declaration

    • (callback: (object: IObject3D) => void): void

    • Parameters

      • callback: (object: IObject3D) => void

        A function with as first argument an Object3D object.

      Returns void

Remarks

Descendants of invisible objects are not traversed.

uiConfig

uiConfig: UiObjectConfig

visible

visible: boolean

Object gets rendered if true.

Default Value

true
