new CircleGeometry(options)

A description 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.
vertexFormat VertexFormat VertexFormat.DEFAULT optional The vertex attributes to be computed.
extrudedHeight Number 0.0 optional The height of the extrusion relative to the ellipsoid.
stRotation Number 0.0 optional The rotation of the texture coordinates, in radians. A positive rotation is counter-clockwise.
// Create a circle.
