		</div>


		<h2>Example</h2>
		<code>var lut = new THREE.Lut( "rainbow", 512 );</code>
		<code>var data = [0, 10.1, 4.2, 3.4, 63, 28];</code>
		<code>lut.setMax(63);</code>
		<code>color = lut.getColor(10);</code>

		<h2>Constructor</h2>


		<h3>[name]( colormap, numberOfColors )</h3>
                <div>
                colormap - optional argument that sets a colormap from prefefined colormaps. Available colormaps are : "rainbow", "cooltowarm", "blackbody".
                numberOfColors - optional argument that sets the number of colors used to represent the data array.
		</div>

		<h2>Properties</h2>
