CircleOutlineGeometry

new Cesium.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 distance in meters between the circle and the ellipsoid surface.
granularity Number 0.02 optional The angular distance between points on the circle in radians.
extrudedHeight Number 0.0 optional The distance in meters between the circle's extruded face and the ellipsoid surface.
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);

staticCesium.CircleOutlineGeometry.packedLength : Number

The number of elements used to pack the object into an array.

Methods

staticCesium.CircleOutlineGeometry.createGeometry(circleGeometry) → Geometry|undefined

Computes the geometric representation of an outline of a circle on an ellipsoid, including its vertices, indices, and a bounding sphere.
Name Type Description
circleGeometry CircleOutlineGeometry A description of the circle.
Returns:
The computed vertices and indices.

staticCesium.CircleOutlineGeometry.pack(value, array, startingIndex) → Array.<Number>

Stores the provided instance into the provided array.
Name Type Default Description
value CircleOutlineGeometry The value to pack.
array Array.<Number> The array to pack into.
startingIndex Number 0 optional The index into the array at which to start packing the elements.
Returns:
The array that was packed into

staticCesium.CircleOutlineGeometry.unpack(array, startingIndex, result) → CircleOutlineGeometry

Retrieves an instance from a packed array.
Name Type Default Description
array Array.<Number> The packed array.
startingIndex Number 0 optional The starting index of the element to be unpacked.
result CircleOutlineGeometry optional The object into which to store the result.
Returns:
The modified result parameter or a new CircleOutlineGeometry instance if one was not provided.
