colour.algebra.cylindrical_to_cartesian(a: ArrayLike) → NDArrayFloat[source]#

Transform specified cylindrical coordinates array \(\rho\phi z\) (radial distance, azimuth and height) to cartesian coordinates array \(xyz\).

Parameters:: a (ArrayLike) – Cylindrical coordinates array \(\rho\phi z\) to transform, where \(\rho\) is in range [0, +inf], \(\phi\) is in range [-pi, pi] radians i.e., [-180, 180] degrees, and \(z\) is in range [0, +inf].
Returns:: Cartesian coordinates array \(xyz\).
Return type:: numpy.ndarray
