Constructor Detail

Ellipsoid

public Ellipsoid(double semiMajorAxis,
                 double semiMinorAxis)

Create a new ellipsoid with the given parameters.

Parameters:

semiMajorAxis - the semi major axis.

semiMinorAxis - the semi minor axis.

Since:

1.1

Ellipsoid

public Ellipsoid(double semiMajorAxis,
                 double semiMinorAxis,
                 double eccentricitySquared)
          throws java.lang.IllegalArgumentException

Create a new ellipsoid with the given parameters. If either the semiMinorAxis or the eccentricitySquared are Double.NaN, then that value is calculated from the other two parameters. An IllegalArgumentException is thrown if both the semiMinorAxis and the eccentricitySquared are Double.NaN.

Parameters:

semiMajorAxis - the semi major axis.

semiMinorAxis - the semi minor axis.

eccentricitySquared - the eccentricity squared.

Throws:

java.lang.IllegalArgumentException - is both the semiMinorAxis and eccentricitySquared parameters are Double.NaN.

Since:

1.1
