GeoCircle class

The GeoCircle class defines an geometric circle with radius. The class may be used to calculate coordinates on the circle given an angle in radians or degrees.

Methods

coordinate(GeoAngle angle, [GeoCoordinate2D? center]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in GeoAngle (either radian or degree). If center is not specified, origin (0,0) is assumed.

inherited

coordinateByDegree(double angle, [GeoCoordinate2D? center]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in degrees. If center is not specified, origin (0,0) is assumed.

inherited

coordinateByRadian(double angle, [GeoCoordinate2D? center, double factor = 1.0]) → GeoCoordinate2D

Get coordinate on an ellipse centered at center at an angle given in radians. If center is not specified, origin (0,0) is assumed. Factor factor is multiplied with the amplitude at the angle to support polar charting

toString() → String

String representation of GeoCircle showing radius.
