		<h1>[name]</h1>

		<div class="desc">An extensible curve object which contains methods for interpolation.</div>
		
		<h2>Examples</h2>
		
		<h3>[example:webgl_geometry_extrude_splines geometry / extrude / splines ]

		<h2>Constructor</h2>


		<h3>[name]()</h3>
		<div>
		This constructor creates a new [name].
		</div>


		<h2>Methods</h2>

		<h3>[method:Vector getPoint]( t )</h3>
		<div>Returns a vector for point t of the curve where t is between 0 and 1</div>

		<h3>[method:Vector getPointAt]( u )</h3>
		<div>Returns a vector for point at relative position in curve according to arc length</div>

		<h3>[method:Array getPoints]( divisions )</h3>
		<div>Get sequence of points using getPoint( t ) </div>

		<h3>[method:Array getSpacedPoints]( divisions )</h3>
		<div>Get sequence of equi-spaced points using getPointAt( u )</div>

		<h3>[method:Float getLength]()</h3>
		<div>Get total curve arc length</div>

		<h3>[method:Array getLengths]( divisions )</h3>
		<div>Get list of cumulative segment lengths</div>

		<h3>[method:null updateArcLengths]()</h3>
		<div>Update the cumlative segment distance cache</div>

		<h3>[method:Float getUtoTmapping]( u, distance )</h3>
		<div>Given u ( 0 .. 1 ), get a t to find p. This gives you points which are equidistant</div>

		<h3>[method:Vector getTangent]( t )</h3>
		<div>Returns a unit vector tangent at t. If the subclassed curve do not implement its tangent derivation, 2 points a small delta apart will be used to find its gradient which seems to give a reasonable approximation</div>

		<h3>[method:Vector getTangentAt]( u )</h3>
		<div>Returns tangent at equidistant point u on the curve</div>
