colour.plotting.plot_sky_luminance_distribution_CIE2003(sky_type: int = 1, Z_s: float = np.radians(45), alpha_s: float = 0.0, method: Literal['Polar', 'Latlong'] | str = 'Polar', imshow_kwargs: dict | None = None, **kwargs: Any) → Tuple[Figure, Axes][source]#

Plot the CIE Standard General Sky luminance distribution for the given sky type.

Parameters:

  • sky_type (int) – CIE Standard General Sky type (1-15).

  • Z_s (float) – Zenith angle \(Z_s\) of the sun in radians.

  • alpha_s (float) – Azimuth angle \(\alpha_s\) of the sun in radians (clockwise from north).

  • method (Literal['Polar', 'Latlong'] | str) –

    Plotting method:

    • "Polar": Fisheye polar projection (square figure).

    • "Latlong": Latitude-longitude projection (2:1 figure).

  • kwargs (Any) – {colour.plotting.artist(), colour.plotting.render()}, See the documentation of the previously listed definitions.

  • imshow_kwargs (dict | None)

Returns:

Current figure and axes.

Return type:

tuple
