colour.plotting.phenomenon Module¶

Optical Phenomenon Plotting¶

Defines the optical phenomenons plotting objects:

• single_rayleigh_scattering_spd_plot()
• the_blue_sky_plot()

colour.plotting.phenomenon.single_rayleigh_scattering_spd_plot(CO2_concentration=300, temperature=288.15, pressure=101325, latitude=0, altitude=0, cmfs='CIE 1931 2 Degree Standard Observer', **kwargs)[source]¶

Plots a single rayleigh scattering spectral power distribution.

Parameters:	CO2_concentration (numeric, optional) – \(CO_2\) concentration in parts per million (ppm). temperature (numeric, optional) – Air temperature \(T[K]\) in kelvin degrees. pressure (numeric) – Surface pressure \(P\) of the measurement site. latitude (numeric, optional) – Latitude of the site in degrees. altitude (numeric, optional) – Altitude of the site in meters. cmfs (unicode, optional) – Standard observer colour matching functions. **kwargs (**) – Keywords arguments.
Returns:	Definition success.
Return type:	bool

Examples

>>> single_rayleigh_scattering_spd_plot()  
True

colour.plotting.phenomenon.the_blue_sky_plot(cmfs='CIE 1931 2 Degree Standard Observer', **kwargs)[source]¶

Plots the blue sky.

Parameters:	cmfs (unicode, optional) – Standard observer colour matching functions. **kwargs (**) – Keywords arguments.
Returns:	Definition success.
Return type:	bool

Examples

>>> the_blue_sky_plot()  
True
