new CircleOutlineGeometry()
A description of the outline of a circle on the ellipsoid.
| Name | Type | Default | Description |
|---|---|---|---|
options.center |
Cartesian3 | The circle's center point in the fixed frame. | |
options.radius |
Number | The radius in meters. | |
options.ellipsoid |
Ellipsoid |
Ellipsoid.WGS84
|
optional The ellipsoid the circle will be on. |
options.height |
Number |
0.0
|
optional The height above the ellipsoid. |
options.granularity |
Number |
0.02
|
optional The angular distance between points on the circle in radians. |
options.extrudedHeight |
Number |
0.0
|
optional The height of the extrusion relative to the ellipsoid. |
options.numberOfVerticalLines |
Number |
16
|
optional Number of lines to draw between the top and bottom of an extruded circle. |
Throws:
-
DeveloperError : radius must be greater than zero.
-
DeveloperError : granularity must be greater than zero.
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);See:
