class colour_visuals.VisualRGBColourspace3D(colourspace: RGB_Colourspace | str | Sequence[RGB_Colourspace | LiteralRGBColourspace | str] = 'sRGB', model: LiteralColourspaceModel | str = 'CIE xyY', colours: ArrayLike | None = None, opacity: float = 1, material: Type[gfx.MeshAbstractMaterial] = gfx.MeshBasicMaterial, wireframe: bool = False, segments: int = 16)[source]#

Bases: Mesh

Create a 3D RGB colourspace volume visual.

Parameters:

  • colourspace (RGB_Colourspace | str | Sequence[RGB_Colourspace | LiteralRGBColourspace | str]) – RGB colourspace to plot the gamut of. colourspaces elements can be of any type or form supported by the colour.plotting.common.filter_RGB_colourspaces() 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 – Thickness of the visual lines.

  • material (Type[gfx.MeshAbstractMaterial]) – Material used to surface the visual geomeetry.

  • wireframe (bool) – Whether to render the visual as a wireframe, i.e., only render edges.

  • segments (int) – Edge segments count for the RGB colourspace cube.
