<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.
