		<h1>[name]</h1>

		<div class="desc">
			Creates a 2d curve in the shape of an ellipse. Setting the
			[page:Number xRadius] equal to the [page:Number yRadius] will result in a circle.
		</div>

		<h2>Example</h2>

<code>
var curve = new THREE.EllipseCurve(
	0,  0,            // ax, aY
	10, 10,           // xRadius, yRadius
	0,  2 * Math.PI,  // aStartAngle, aEndAngle
	false,            // aClockwise
	0                 // aRotation
);

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 ellipse = new THREE.Line( geometry, material );
</code>

		<h2>Constructor</h2>


		<h3>[name]( [page:Float aX], [page:Float aY], [page:Float xRadius], [page:Float yRadius], [page:Radians aStartAngle], [page:Radians aEndAngle], [page:Boolean aClockwise], [page:Radians aRotation] )</h3>
		<div>
			[page:Float aX] – The X center of the ellipse.<br/>
			[page:Float aY] – The Y center of the ellipse.<br/>
			[page:Float xRadius] – The radius of the ellipse in the x direction.<br/>
			[page:Float yRadius] – The radius of the ellipse in the y direction.<br/>
			[page:Radians aStartAngle] – The start angle of the curve in radians starting from the middle right side.<br/>
			[page:Radians aEndAngle] – The end angle of the curve in radians starting from the middle right side.<br/>
			[page:Boolean aClockwise] – Whether the ellipse is drawn clockwise.<br/>
			[page:Radians aRotation]  – The rotation angle of the ellipse in radians, counterclockwise from the positive X axis (optional). Default is *0*.<br/><br/>

			<em>Note:</em> When going clockwise it's best to set the start angle to (Math.PI * 2) and then work towards lower numbers.
		</div>

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

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

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