colour.volume.XYZ_outer_surface¶
-
colour.volume.XYZ_outer_surface(interval=10, cmfs=XYZ_ColourMatchingFunctions(name='CIE 1931 2 Degree Standard Observer', ...), illuminant=SpectralDistribution(name='1 Constant', ...))[source]¶ Generates the CIE XYZ colourspace outer surface for given colour matching functions using multi-spectral conversion of pulse waves to CIE XYZ tristimulus values.
Parameters: - interval (int, optional) – Wavelength \(\lambda_{i}\) range interval used to compute the pulse waves.
- cmfs (XYZ_ColourMatchingFunctions, optional) – Standard observer colour matching functions.
- illuminant (SpectralDistribution, optional) – Illuminant spectral distribution.
Returns: Outer surface CIE XYZ tristimulus values.
Return type: ndarray
