		<h3>[name]( [param:Object parameters] )</h3>
		<p>
			[page:Object parameters] - (optional) an object with one or more properties defining the material's appearance.
			Any property of the material (including any property inherited from [page:Material]) can be passed in here.<br /><br />

			The exception is the property [page:Hexadecimal color], which can be passed in as a hexadecimal
			string and is *0xffffff* (white) by default. [page:Color.set]( color ) is called internally.
		</p>

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

		<h3>[property:Color color]</h3>
		<p>[page:Color] of the material, by default set to white (0xffffff).</p>

		<h3>[property:Boolean isPointsMaterial]</h3>
		<p>
			Used to check whether this or derived classes are points materials. Default is *true*.<br /><br />

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

		<h3>[property:Texture map]</h3>

		<p>Sets the color of the points using data from a [page:Texture].</p>

		<h3>[property:Boolean morphTargets]</h3>
		<p>Define whether the material uses morphTargets. Default is false.</p>

		<h3>[property:Number size]</h3>
		<p>Sets the size of the points. Default is 1.0.</p>

		<h3>[property:Boolean sizeAttenuation]</h3>
		<p>Specify whether points' size is attenuated by the camera depth. (Perspective camera only.) Default is true.</p>
