[page:Object3D] → [page:Light] →
[name]
Affects objects using [page:MeshLambertMaterial] or [page:MeshPhongMaterial].
Example
// White directional light at half intensity shining from the top.
var directionalLight = new THREE.DirectionalLight( 0xffffff, 0.5 );
directionalLight.position.set( 0, 1, 0 );
scene.add( directionalLight );
Constructor
[name]([page:Integer hex], [page:Float intensity])
[page:Integer hex] -- Numeric value of the RGB component of the color.
[page:Float intensity] -- Numeric value of the light's strength/intensity.
Creates a light that shines from a specific direction not from a specific position. This light will behave
as though it is infinitely far away and the rays produced from it are all parallel. The best
analogy would be a light source that acts like the sun: the sun is so far away that all sunlight
hitting objects comes from the same angle.
Properties
[property:Object3D target]
Target used for shadow camera orientation.
[property:Float intensity]
Light's intensity.
Default — *1.0*.
[property:Boolean onlyShadow]
If set to *true* light will only cast shadow but not contribute any lighting (as if *intensity* was 0 but cheaper to compute).
Default — *false*.
[property:Float shadowCameraNear]
Orthographic shadow camera frustum parameter.
Default — *50*.
[property:Float shadowCameraFar]
Orthographic shadow camera frustum parameter.
Default — *5000*.
[property:Float shadowCameraLeft]
Orthographic shadow camera frustum parameter.
Default — *-500*.
[property:Float shadowCameraRight]
Orthographic shadow camera frustum parameter.
Default — *500*.
[property:Float shadowCameraTop]
Orthographic shadow camera frustum parameter.
Default — *500*.
[property:Float shadowCameraBottom]
Orthographic shadow camera frustum parameter.
Default — *-500*.
[property:Boolean shadowCameraVisible]
Show debug shadow camera frustum.
Default — *false*.
[property:Float shadowBias]
Shadow map bias.
Default — *0*.
[property:Float shadowDarkness]
Darkness of shadow casted by this light (from *0* to *1*).
Default — *0.5*.
[property:Integer shadowMapWidth]
Shadow map texture width in pixels.
Default — *512*.
[property:Integer shadowMapHeight]
Shadow map texture height in pixels.
Default — *512*.
[property:Boolean shadowCascade]
???
Default — *false*.
[property:Vector3 shadowCascadeOffset]
???
Default — *Three.Vector3( 0, 0, -1000 )*.
[property:Integer shadowCascadeCount]
???
Default — *2*.
[property:Array shadowCascadeBias]
???
Default — [ 0, 0, 0 ].
[property:Array shadowCascadeWidth]

[property:Array shadowCascadeArray]
???
Default — [ ].
[property:RenderTarget shadowMap]
???
Default — *null*.
[property:Integer shadowMapSize]
???
Default — *null*.
[property:Camera shadowCamera]
???
Default — *null*.
[property:Matrix shadowMatrix]
