Group
Create a 2D Pointer’s Gamut visual.
- Parameters:
method (Literal['CIE 1931', 'CIE 1960 UCS', 'CIE 1976 UCS'] | str) – Chromaticity Diagram method.
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.
