EllipseOutlineGeometry

new EllipseOutlineGeometry()

A description of the outline of an ellipse on an ellipsoid.
Name Type 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 Ellipsoid.WGS84 optional The ellipsoid the ellipse will be on.
options.height Number 0.0 optional The height above the ellipsoid.
options.extrudedHeight Number optional The height of the extrusion.
options.rotation Number 0.0 optional The angle from north (clockwise) in radians. The default is zero.
options.granularity Number 0.02 optional The angular distance between points on the ellipse in radians.
options.numberOfVerticalLines Number 16 optional Number of lines to draw between the top and bottom surface of an extruded ellipse.
Throws:
Example:
var ellipse = new Cesium.EllipseOutlineGeometry({
  center : Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883),
  semiMajorAxis : 500000.0,
  semiMinorAxis : 300000.0,
  rotation : Cesium.Math.toRadians(60.0)
});
var geometry = Cesium.EllipseOutlineGeometry.createGeometry(ellipse);
