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.

<h2>Code Example</h2>
|
||
|
|
|
||
|
|
<code>
|
||
|
|
const curve = new THREE.EllipseCurve(
|
||
|
|
0, 0, // ax, aY
|
||
|
|
10, 10, // xRadius, yRadius
|
||
|
|
0, 2 * Math.PI, // aStartAngle, aEndAngle
|
||
|
|
false, // aClockwise
|
||
|
|
0 // aRotation
|
||
|
|
);
|
||
|
|
|
||
|
|
const points = curve.getPoints( 50 );
|
||
|
|
const geometry = new THREE.BufferGeometry().setFromPoints( points );
|
||
|
|
|
||
|
|
const material = new THREE.LineBasicMaterial( { color: 0xff0000 } );
|
||
|
|
|
||
|
|
// Create the final object to add to the scene
|
||
|
|
const ellipse = new THREE.Line( geometry, material );

|
<p>
|
||
|
|
[page:Float aX] – The X center of the ellipse. Default is `0`.<br/>
|
||
|
|
[page:Float aY] – The Y center of the ellipse. Default is `0`.<br/>
|
||
|
|
[page:Float xRadius] – The radius of the ellipse in the x direction. Default is `1`.<br/>
|
||
|
|
[page:Float yRadius] – The radius of the ellipse in the y direction. Default is `1`.<br/>
|
||
|
|
[page:Radians aStartAngle] – The start angle of the curve in radians starting from the positive X axis. Default is `0`.<br/>
|
||
|
|
[page:Radians aEndAngle] – The end angle of the curve in radians starting from the positive X axis. Default is `2 x Math.PI`.<br/>
|
||
|
|
[page:Boolean aClockwise] – Whether the ellipse is drawn clockwise. Default is `false`.<br/>
|
||
|
|
[page:Radians aRotation] – The rotation angle of the ellipse in radians, counterclockwise from the positive X axis (optional). Default is `0`.<br/><br/>
