CircleOutlineGeometry

new CircleOutlineGeometry(options)

A description of the outline of a circle on the ellipsoid.
Name Type Description
options Object Object with the following properties:
Name Type Default Description
center Cartesian3 The circle's center point in the fixed frame.
radius Number The radius in meters.
ellipsoid Ellipsoid Ellipsoid.WGS84 optional The ellipsoid the circle will be on.
height Number 0.0 optional The height above the ellipsoid.
granularity Number 0.02 optional The angular distance between points on the circle in radians.
extrudedHeight Number 0.0 optional The height of the extrusion relative to the ellipsoid.
numberOfVerticalLines Number 16 optional Number of lines to draw between the top and bottom of an extruded circle.
Throws:
Example:
// Create a circle.
var circle = new Cesium.CircleOutlineGeometry({
  center : Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883),
  radius : 100000.0
});
var geometry = Cesium.CircleOutlineGeometry.createGeometry(circle);
