		<h1>[name]</h1>

		<div class="desc">Creates a 2d curve in the shape of an ellipse.</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
);

var path = new THREE.Path( curve.getPoints( 50 ) );
var geometry = path.createPointsGeometry( 50 );
var material = new THREE.LineBasicMaterial( { color : 0xff0000 } );

// Create the final Object3d 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] )</h3>
		<div>
			aX – The X center of the ellipse<br/>
			aY – The Y center of the ellipse<br/>
			xRadius – The radius of the ellipse in the x direction<br/>
			yRadius – The radius of the ellipse in the y direction<br/>
			aStartAngle – The start angle of the curve in radians starting from the middle right side<br/>
			aEndAngle – The end angle of the curve in radians starting from the middle right side<br/>
			aClockwise – Whether the ellipse is clockwise<br/><br/>
			
			<strong>Note:</strong> When going clockwise it's best to set the start angle to (Math.PI * 2) and then work towards lower numbers.
		</div>
