- <h1>[name]</h1>
- <p 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.
- </p>
- <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 );
- </code>
- <h2>Constructor</h2>
- <h3>
- [name]( [param:Float aX], [param:Float aY], [param:Float xRadius],
- [param:Float yRadius], [param:Radians aStartAngle], [param:Radians aEndAngle], [param:Boolean aClockwise], [param:Radians aRotation] )
- </h3>
- <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 />
