		<h1>[name]</h1>

		<p class="desc">
			Create a smooth 2d
			<a href="http://en.wikipedia.org/wiki/B%C3%A9zier_curve#mediaviewer/File:Bezier_curve.svg" target="_blank">cubic bezier curve</a>,
			defined by a start point, endpoint and two control points.
		</p>

		<h2>Code Example</h2>

		<code>
		const curve = new THREE.CubicBezierCurve(
			new THREE.Vector2( -10, 0 ),
			new THREE.Vector2( -5, 15 ),
			new THREE.Vector2( 20, 15 ),
			new THREE.Vector2( 10, 0 )
		);

		const points = curve.getPoints( 50 );
		const geometry = new THREE.BufferGeometry().setFromPoints( points );

		const material = new THREE.LineBasicMaterial( { color : 0xff0000 } );

		// Create the final object to add to the scene
		const curveObject = new THREE.Line( geometry, material );
		</code>

		<h2>Constructor</h2>


		<h3>[name] ( [param:Vector2 v0], [param:Vector2 v1], [param:Vector2 v2], [param:Vector2 v3] )</h3>
