colour.sd_ones

colour.sd_ones(shape: SpectralShape = SPECTRAL_SHAPE_DEFAULT, **kwargs: Any) → SpectralDistribution

Return a spectral distribution of given spectral shape filled with ones.

Parameters:

• shape (SpectralShape) – Spectral shape used to create the spectral distribution.

• kwargs (Any) – {colour.sd_constant()}, See the documentation of the previously listed definition.

Returns:

Ones filled spectral distribution.

Return type:

colour.SpectralDistribution

Notes

• By default, the spectral distribution will use the shape given by colour.SPECTRAL_SHAPE_DEFAULT attribute.

• The interpolator is set to colour.LinearInterpolator class.

Examples

>>> sd = sd_ones()
>>> sd.shape
SpectralShape(360.0, 780.0, 1.0)
>>> sd[400]
1.0
