Computes boundary positions for a circle on the specified centralBody with the specified center, radius and granularity.

The computed positions are at the same altitude as the input center.

Lower granularities are more precise but result in more positions.

Parameters:

centralBody - The central body to compute the circle on.

center - The center of the circle, in the centralBody's fixed reference frame.

radius - The radius of the circle, in meters.

granularity - The angular separation, in radians, of positions along the boundary.

Returns:

A SurfaceShapesResult object representing the boundary of the circle, in the centralBody's fixed reference frame.

Throws:

ArgumentNullException - centralBody is null.

ArgumentOutOfRangeException - radius and granularity must be greater than zero.
