new CircleGeometry()
A description 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.vertexFormat |
VertexFormat |
VertexFormat.DEFAULT
|
optional The vertex attributes to be computed. |
options.extrudedHeight |
Number |
0.0
|
optional The height of the extrusion relative to the ellipsoid. |
options.stRotation |
Number |
0.0
|
optional The rotation of the texture coordinates, in radians. A positive rotation is counter-clockwise. |
Throws:
-
DeveloperError : radius must be greater than zero.
-
DeveloperError : granularity must be greater than zero.
Example:
// Create a circle.
var circle = new Cesium.CircleGeometry({
center : Cesium.Cartesian3.fromDegrees(-75.59777, 40.03883),
radius : 100000.0
});
var geometry = Cesium.CircleGeometry.createGeometry(circle);
