<h1>[name]</h1>
<p class="desc">
A light source positioned directly above the scene, with color fading from the
sky color to the ground color. <br /><br />
This light cannot be used to cast shadows.
</p>
<h2>Example</h2>
<div>
[example:webgl_lights_hemisphere lights / hemisphere ]<br />
[example:misc_controls_pointerlock controls / pointerlock ]<br />
[example:webgl_decals decals ]<br />
[example:webgl_loader_collada_kinematics loader / collada / kinematics ]<br />

</div>
<code>
var light = new THREE.HemisphereLight( 0xffffbb, 0x080820, 1 );
scene.add( light );
</code>
<h2>Constructor</h2>
<h3>[name]( [param:Integer skyColor], [param:Integer groundColor], [param:Float intensity] )</h3>
<p>
[page:Integer skyColor] - (optional) hexadecimal color of the sky. Default is 0xffffff.<br />
[page:Integer groundColor] - (optional) hexadecimal color of the ground. Default is 0xffffff.<br />
[page:Float intensity] - (optional) numeric value of the light's strength/intensity. Default is 1.<br /><br />
Creates a new [name].
</p>
<h2>Properties</h2>
<p>
See the base [page:Light Light] class for common properties.
</p>
<h3>[property:Boolean castShadow]</h3>
<p>
This is set to *undefined* in the constructor as hemisphere lights cannot cast shadows.
</p>
<h3>[property:Float color]</h3>
<p>
The light's sky color, as passed in the constructor.
Default is a new [page:Color] set to white (0xffffff).
</p>
<h3>[property:Float groundColor]</h3>
<p>
The light's ground color, as passed in the constructor.
Default is a new [page:Color] set to white (0xffffff).
</p>
<h3>[property:Vector3 position]</h3>
<p>
This is set equal to [page:Object3D.DefaultUp] (0, 1, 0), so that the light shines from the top down.
</p>
<h2>Methods</h2>
See the base [page:Light Light] class for common methods.
<h3>[method:HemisphereLight copy]( [param:HemisphereLight source] )</h3>
<p>
Copies the value of [page:.color color], [page:.intensity intensity] and
[page:.groundColor groundColor] from the [page:Light source] light into this one.
