[name]
Creates a 2d curve in the shape of an ellipse.
Example
var curve = new THREE.EllipseCurve(
0, 0, // ax, aY
10, 10, // xRadius, yRadius
0, 2 * Math.PI, // aStartAngle, aEndAngle
false, // aClockwise
0 // aRotation
);
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 );
Constructor
[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] )
aX – The X center of the ellipse
aY – The Y center of the ellipse
xRadius – The radius of the ellipse in the x direction
yRadius – The radius of the ellipse in the y direction
aStartAngle – The start angle of the curve in radians starting from the middle right side
aEndAngle – The end angle of the curve in radians starting from the middle right side
aClockwise – Whether the ellipse is clockwise
aRotation – The rotation angle of the ellipse in radians, counterclockwise from the positive X axis (optional)
Note: When going clockwise it's best to set the start angle to (Math.PI * 2) and then work towards lower numbers.
