Class PointLight

A light that gets emitted from a single point in all directions

Remarks

A common use case for this is to replicate the light emitted from a bare lightbulb.

Example

const light = new THREE.PointLight(0xff0000, 1, 100);
light.position.set(50, 50, 50);
scene.add(light);

Properties

animations

animations: AnimationClip[]

Array with object's animation clips.

Default Value

[]

castShadow

castShadow: boolean

See

PointLightShadow for details.

Default Value

false

children

children: Object3D<Object3DEventMap>[]

Array with object's children.

See

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

Default Value

[]

color

color: Color

Color of the light. \

Default Value

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

`Optional`customDepthMaterial

customDepthMaterial?: Material

Custom depth material to be used when rendering to the depth map.

Remarks

Can only be used in context of meshes.

Default Value

undefined

`Optional`customDistanceMaterial

customDistanceMaterial?: Material

Same as customDepthMaterial, but used with THREE.Object3DPointLight | PointLight.

Default Value

undefined

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

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 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

- Defined in ../node_modules/@types/three/src/core/Object3D.d.ts:561

updateMatrix

updateMatrix(): void
Updates local transform.

Returns void
Inherited from Light.updateMatrix
- Defined in ../node_modules/@types/three/src/core/Object3D.d.ts:573

updateMatrixWorld

updateMatrixWorld(force?): void
Updates the global transform of the object. And will update the object descendants if .matrixWorldNeedsUpdate is set to true or if the force parameter is set to true.
Parameters
- Optionalforce: boolean
  A boolean that can be used to bypass .matrixWorldAutoUpdate, to recalculate the world matrix of the object and descendants on the current frame. Useful if you cannot wait for the renderer to update it on the next frame, assuming .matrixWorldAutoUpdate set to true.
Returns void
Inherited from Light.updateMatrixWorld
- Defined in ../node_modules/@types/three/src/core/Object3D.d.ts:581

updateWorldMatrix

updateWorldMatrix(updateParents, updateChildren): void
Updates the global transform of the object.
Parameters
- updateParents: boolean
  Recursively updates global transform of ancestors.
- updateChildren: boolean
  Recursively updates global transform of descendants.
Returns void
Inherited from Light.updateWorldMatrix
- Defined in ../node_modules/@types/three/src/core/Object3D.d.ts:588

worldToLocal

worldToLocal(vector): Vector3
Converts the vector from world space to this object's local space.
Parameters
- vector: Vector3
  A vector representing a position in world space.
Returns Vector3
