Constructor Detail

SphericalCoordinates

public SphericalCoordinates(double delta,
                            double alpha,
                            double norm)

Build a new instance. Angles are normalized around 0.

Parameters:

delta - elevation δ of the point

alpha - azimuth α of the point

norm - norm of the point

SphericalCoordinates

public SphericalCoordinates(double delta,
                            double alpha,

                            boolean normalizeAngles)

Build a new instance.

Parameters:

delta - elevation δ of the point

alpha - azimuth α of the point

norm - norm of the point

normalizeAngles - true if angles should be centered around 0, false if kept as provided
