		<h1>[name]</h1>

		<p class="desc">
			Create a smooth 3d
			<a href="http://en.wikipedia.org/wiki/B%C3%A9zier_curve#mediaviewer/File:B%C3%A9zier_2_big.gif" target="_blank">quadratic bezier curve</a>,
			defined by a startpoint, endpoint and a single control point.
		</p>

		<h2>Example</h2>

<code>
var curve = new THREE.QuadraticBezierCurve3(
	new THREE.Vector3( -10, 0, 0 ),
	new THREE.Vector3( 20, 15, 0 ),
	new THREE.Vector3( 10, 0, 0 )
);

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

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

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

		<h2>Constructor</h2>


		<h3>[name]( [param:Vector3 v0], [param:Vector3 v1], [param:Vector3 v2] )</h3>
		<p>
			[page:Vector3 v0] – The starting point<br/>
			[page:Vector3 v1] – The middle control point<br/>
			[page:Vector3 v2] – The ending point<br/>
		</p>


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

		<h3>[property:Boolean isQuadraticBezierCurve3]</h3>
		<p>
			Used to check whether this or derived classes are QuadraticBezierCurve3s. Default is *true*.<br /><br />

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

		<h3>[property:Vector3 v0]</h3>
		<p>The startpoint.</p>

		<h3>[property:Vector3 v1]</h3>
		<p>The control point.</p>

		<h3>[property:Vector3 v2]</h3>
		<p>The endpoint.</p>
