colour.sd_ones(shape=SpectralShape(360, 780, 1))[source]¶

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

Parameters: shape (SpectralShape, optional) – Spectral shape used to create the spectral distribution.
Returns: Ones filled spectral distribution.
Return type: SpectralDistribution

Notes

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

Examples

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