		<h2>Example</h2>

			var tz = 0;

			return new THREE.Vector3( tx, ty, tz ).multiplyScalar( this.scale );

		<h2>Constructor</h2>


		<h3>[name]([param:Curve path], [param:Integer tubularSegments], [param:Float radius], [param:Integer radialSegments], [param:Boolean closed])</h3>
		<p>
		path — [page:Curve] - A path that inherits from the [page:Curve] base class<br />
		tubularSegments — [page:Integer] - The number of segments that make up the tube, default is 64<br />
		radius — [page:Float] - The radius of the tube, default is 1<br />
		radialSegments — [page:Integer] - The number of segments that make up the cross-section, default is 8 <br />
		closed — [page:Boolean] Is the tube open or closed, default is false <br />
		</p>


		<h2>Properties</h2>

		<h3>[property:Object parameters]</h3>
		<p>
		An object with a property for each of the constructor parameters. Any modification after instantiation does not change the geometry.
		</p>

		<h3>[property:Array tangents]</h3>
		<p>
		An array of [page:Vector3] tangents
		</p>

		<h3>[property:Array normals]</h3>
		<p>
		An array of [page:Vector3] normals
		</p>

		<h3>[property:Array binormals]</h3>
		<p>
		An array of [page:Vector3] binormals
		</p>
