Module cartesianBase

Convert spherical, polar (r, theta, phi) to cartesian (x, y, z) coordinates.

Arguments:

• theta - Inclination theta (degrees with respect to the positive z-axis), required if r_rtp is scalar, ignored otherwise.
• phi - Azimuthal angle phi (degrees), like theta.

Convert spherical, polar (r, theta, phi) to cartesian (x, y, z) coordinates.

Arguments:

• r_rtp - Radial distance (scalar, conventially meter) or a previous RadiusThetaPhi3Tuple instance.
• theta - Inclination theta (radians with respect to the positive z-axis), required if r_rtp is scalar, ignored otherwise.
• phi - Azimuthal angle phi (radians), like theta.
• name_Cartesian_and_kwds - Optional name=NN (str), a Cartesian=None class to return the coordinates and optional, additional Cartesian keyword arguments.

Returns:

A Cartesian(x, y, z) instance or if no Cartesian keyword argument is given a Vector3Tuple(x, y, z), with x, y and z in the same units as radius r, meter conventionally.

Raises:

• TypeError - Invalid r_rtp, theta, phi or name_Cartesian_and_kwds item.

Convert cartesian (x, y, z) to spherical, polar (r, theta, phi) coordinates.

Returns:

RadiusThetaPhi3Tuple(r, theta, phi) with theta and phi, both in Degrees.

Convert cartesian (x, y, z) to spherical, polar (r, theta, phi) coordinates.

Arguments:

• x_xyz - X component (scalar) or a cartesian (Cartesian, Ecef9Tuple, Nvector, Vector3d, Vector3Tuple, Vector4Tuple or a tuple or list of 3+ scalar items) if no y_z specified.
• y - Y component (scalar), required if x_xyz is scalar, ignored otherwise.
• z - Z component (scalar), like y.
• name - Optional name=NN (str).

Returns:

RadiusThetaPhi3Tuple(r, theta, phi) with radial distance r (meter, same units as x, y and z), inclination theta (with respect to the positive z-axis) and azimuthal angle phi, both in Radians.
