Detailed Description

Class holding the azimuth and inclination angles of spherical coordinates.

The notation is the one used in "Antenna Theory - Analysis and Design", C.A. Balanis, Wiley, 2nd Ed., section 2.2 "Radiation pattern". This notation corresponds to the standard spherical coordinates, with azimuth measured counterclockwise in the x-y plane off the x-axis, and inclination measured off the z-axis. Azimuth is consistently normalized to be in [-M_PI, M_PI).

Constructor & Destructor Documentation

◆ Angles() [1/4]

ns3::Angles::Angles	(	double	azimuth,
		double	inclination )

This constructor allows to specify azimuth and inclination.

Inclination must be in [0, M_PI], while azimuth is automatically normalized in [-M_PI, M_PI)

Parameters

azimuth	the azimuth angle in radians
inclination	the inclination angle in radians

◆ Angles() [2/4]

ns3::Angles::Angles ( Vector v )

This constructor will initialize azimuth and inclination by converting the given 3D vector from cartesian coordinates to spherical coordinates Note: azimuth and inclination angles for a zero-length vector are not defined and are thus initialized to NAN.

Parameters

v	the 3D vector in cartesian coordinates

◆ Angles() [3/4]

ns3::Angles::Angles	(	Vector	v,
		Vector	o )

This constructor initializes an Angles instance with the angles of the spherical coordinates of point v respect to point o.

Parameters

v	the point (in cartesian coordinates) for which the angles are determined
o	the origin (in cartesian coordinates) of the spherical coordinate system

void ns3::Angles::NormalizeAngles ( )

private

Normalize the angle azimuth angle range between in [-M_PI, M_PI) while checking if the angle is valid, i.e., finite and within the bounds.

Note: while an arbitrary value for the azimuth angle is valid and can be wrapped in [-M_PI, M_PI), an inclination angle outside the [0, M_PI] range can be ambiguous and is thus not valid.
