colour.algebra.spherical_to_cartesian¶
- colour.algebra.spherical_to_cartesian(a)[source]¶
Transforms given spherical coordinates array \(\rho\theta\phi\) (radial distance, inclination or elevation and azimuth) to cartesian coordinates array \(xyz\).
- Parameters
a (array_like) – Spherical coordinates array \(\rho\theta\phi\) to transform, \(\rho\) is in range [0, +inf], \(\theta\) is in range [0, pi] radians, i.e. [0, 180] degrees, and \(\phi\) is in range [-pi, pi] radians, i.e. [-180, 180] degrees.
- Returns
Cartesian coordinates array \(xyz\).
- Return type
ndarray
