Bases: Line

Create a Rösch-MacAdam visual.

Parameters:

  • cmfs (MultiSpectralDistributions | str | Sequence[MultiSpectralDistributions | str]) – Standard observer colour matching functions, default to the CIE 1931 2 Degree Standard Observer. cmfs can be of any type or form supported by the colour.plotting.common.filter_cmfs() definition.

  • illuminant (SpectralDistribution | str | Sequence[SpectralDistribution | str]) – Illuminant spectral distribution, default to CIE Illuminant E. illuminant can be of any type or form supported by the colour.plotting.common.filter_illuminants() definition.

  • model (LiteralColourspaceModel | str) – Colourspace model, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

  • colours (ArrayLike | None) – Colours of the visual, if None, the colours are computed from the visual geometry.

  • opacity (float) – Opacity of the visual.

  • thickness (float) – Thickness of the visual lines.
