		<h2>Constructor</h2>


		<h3>[name]([page:Integer hex], [page:Float intensity], [page:Number distance], [page:Float decay])</h3>
		<div>
		[page:Integer hex] — Numeric value of the RGB component of the color. <br />
		[page:Float intensity] — Numeric value of the light's strength/intensity. <br />
		[page:Number distance] -- The distance of the light where the intensity is 0. When distance is 0, then the distance is endless. <br />
		[page:Float decay] -- The amount the light dims along the distance of the light.
		</div>
		<div>
		Creates a light at a specific position in the scene.  The light shines in all directions (roughly similar to a light bulb.)
	
		</div>


		<h2>Properties</h2>

		<h3>[property:Float intensity]</h3>
		<div>
			Light's intensity.<br />
			Default - *1.0*.
		</div>

		<h3>[property: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>[property:Float decay]</h3>
		<div>
			The amount the light dims along the distance of the light<br />
			Default — *1*.
		</div>
		
		<h2>Methods</h2>
		
		<h3>[method:PointLight clone]()</h3>
		<div>
		<br />
		It returns a clone of PointLight.
		</div>
		
		<h3>[method:JSON toJSON]()</h3>
		<div>
		Return PointLight data in JSON format.
		</div>
