		<h1>[name]</h1>

		<div class="desc">
			A light source positioned directly above the scene, with color fading from the sky color to the ground color.
			This light cannot be used to cast shadows.
		</div>

		<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 />
		  [example:webgl_materials_lightmap materials / lightmap ]<br />
		  [example:webgl_shaders_ocean shaders / ocean ]
		</div>

<code>
var light = new THREE.HemisphereLight( 0xffffbb, 0x080820, 1 );
scene.add( light );
</code>

		<h2>Constructor</h2>
		<h3>[name]( [page:Integer skyColor], [page:Integer groundColor], [page:Float intensity] )</h3>
    <div>
		[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].
		</div>

		<h2>Properties</h2>
		<div>
			See the base [page:Light Light] class for common properties.
		</div>

		<h3>[property:Boolean castShadow]</h3>
		<div>
			This is set to *undefined* in the constructor as hemisphere lights cannot cast shadows.
		</div>


		<h3>[property:Float color]</h3>
		<div>
			The light's sky color, as passed in the constructor.
			Default is a new [page:Color] set to white (0xffffff).
		</div>

		<h3>[property:Float groundColor]</h3>
		<div>
			The light's ground color, as passed in the constructor.
			Default is a new [page:Color] set to white (0xffffff).
		</div>

		<h3>[property:Boolean isHemisphereLight]</h3>
		<div>
			Used to check whether this or derived classes are hemisphere lights. Default is *true*.<br /><br />

			You should not change this, as it used internally for optimisation.
		</div>

		<h3>[property:Vector3 position]</h3>
		<div>
			This is set equal to [page:Object3D.DefaultUp], so that the light shines from the top down.
		</div>


		<h2>Methods</h2>

		See the base [page:Light Light] class for common methods.

		<h3>[method:HemisphereLight copy]( [page:HemisphereLight source] )</h3>
		<div>
			Copies the value of [page:.color color], [page:.intensity intensity] and
			[page:.groundColor groundColor] from the [page:Light source] light into this one.
		</div>
