[page:Object3D] → [page:Light] →
[name]
A point light that can cast shadow in one direction.
Affects objects using [page:MeshLambertMaterial] or [page:MeshPhongMaterial].
Example
// white spotlight shining from the side, casting shadow
var spotLight = new THREE.SpotLight( 0xffffff );
spotLight.position.set( 100, 1000, 100 );
spotLight.castShadow = true;
spotLight.shadowMapWidth = 1024;
spotLight.shadowMapHeight = 1024;
spotLight.shadowCameraNear = 500;
spotLight.shadowCameraFar = 4000;
spotLight.shadowCameraFov = 30;
scene.add( spotLight );

Properties
.[page:Object3D target]
Spotlight focus points at target.position.
Default position — *(0,0,0)*.
.[page:Float intensity]
Light's intensity.
Default — *1.0*.
.[page:Float distance]
If non-zero, light will attenuate linearly from maximum intensity at light *position* down to zero at *distance*.
Default — *0.0*.
.[page:Float angle]
Maximum extent of the spotlight, in radians, from its direction. Should be no more than *Math.PI/2*.
Default — *Math.PI/3*.
.[page:Float exponent]
Rapidity of the falloff of light from its target direction.
Default — *10.0*.
.[page:Boolean castShadow]
If set to *true* light will cast dynamic shadows. *Warning*: This is expensive and requires tweaking to get shadows looking right.
Default — *false*.
.[page: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*.
.[page:Float shadowCameraNear]
Perspective shadow camera frustum near parameter.
Default — *50*.
.[page:Float shadowCameraFar]
Perspective shadow camera frustum far parameter.
Default — *5000*.
.[page:Float shadowCameraFov]
Perspective shadow camera frustum field of view parameter.
Default — *50*.
.[page:Boolean shadowCameraVisible]
Show debug shadow camera frustum.
Default — *false*.
.[page:Float shadowBias]
Shadow map bias.
Default — *0*.
.[page:Float shadowDarkness]
Darkness of shadow casted by this light (from *0* to *1*).
Default — *0.5*.
.[page:Integer shadowMapWidth]
Shadow map texture width in pixels.
Default — *512*.
.[page:Integer shadowMapHeight]
Shadow map texture height in pixels.
Default — *512*.
.[page:Float shadowBias]
Shadow map bias.
Default — *0*.
.[page:Float shadowDarkness]
Darkness of shadow casted by this light (from *0* to *1*).
Default — *0.5*.
.[page:Integer shadowMapWidth]
Shadow map texture width in pixels.
Default — *512*.
.[page:Integer shadowMapHeight]
Shadow map texture height in pixels.
Default — *512*.
