<h2>Properties</h2>
<h3>.[page:Vector3 todo]</h3>
<h3>.[page:Vector3 position]</h3>
<div>
Light's position.<br />
Default — *new THREE.Vector3()*.
</div>
<h3>.[page:Float intensity]</h3>
<div>
Light's intensity.<br />
Default — *1.0*.
</div>
<h3>.[page:Float distance]</h3>
<div>
If non-zero, light will attenuate linearly from maximum intensity at light *position* down to zero at *distance*.<br />
Default — *0.0*.
</div>
<h3>.[page:Boolean castShadow]</h3>
<div>
If set to *true* light will cast dynamic shadows. *Warning*: This is expensive and requires tweaking to get shadows looking right.<br />
Default — *false*.
</div>
<h3>.[page:Boolean onlyShadow]</h3>
<div>
If set to *true* light will only cast shadow but not contribute any lighting (as if *intensity* was 0 but cheaper to compute).<br />
Default — *false*.
</div>
<h3>.[page:Float shadowCameraNear]</h3>
<div>
Perspective shadow camera frustum <em>near</em> parameter.<br />
Default — *50*.

<div>
Darkness of shadow casted by this light (from *0* to *1*).<br />
Default — *0.5*.
