A description of the outline of an ellipse on an ellipsoid.

Parameters:
Name Type Argument Default Description
options.center Cartesian3 The ellipse's center point in the fixed frame.
options.semiMajorAxis Number The length of the ellipse's semi-major axis in meters.
options.semiMinorAxis Number The length of the ellipse's semi-minor axis in meters.
options.ellipsoid Ellipsoid <optional>
Ellipsoid.WGS84 The ellipsoid the ellipse will be on.
options.height Number <optional>
0.0 The height above the ellipsoid.
options.extrudedHeight Number <optional>
The height of the extrusion.
options.rotation Number <optional>
0.0 The angle from north (clockwise) in radians. The default is zero.
options.granularity Number <optional>
0.02 The angular distance between points on the ellipse in radians.
options.numberOfVerticalLines Number <optional>
16 Number of lines to draw between the top and bottom surface of an extruded ellipse.
Throws:
Example
var ellipsoid = Cesium.Ellipsoid.WGS84;
var ellipse = new Cesium.EllipseOutlineGeometry({
  ellipsoid : ellipsoid,
  center : ellipsoid.cartographicToCartesian(Cesium.Cartographic.fromDegrees(-75.59777, 40.03883)),
  semiMajorAxis : 500000.0,
  semiMinorAxis : 300000.0,
  rotation : Cesium.Math.toRadians(60.0)
});
var geometry = Cesium.EllipseOutlineGeometry.createGeometry(ellipse);
