Plot the section colours of given trimesh hull along given axis and origin.

Parameters

  • hull (trimesh.Trimesh) – Trimesh hull.

  • model (Union[Literal[('CAM02LCD', 'CAM02SCD', 'CAM02UCS', 'CAM16LCD', 'CAM16SCD', 'CAM16UCS', 'CIE XYZ', 'CIE xyY', 'CIE Lab', 'CIE Luv', 'CIE UCS', 'CIE UVW', 'DIN99', 'Hunter Lab', 'Hunter Rdab', 'ICaCb', 'ICtCp', 'IPT', 'IgPgTg', 'Jzazbz', 'OSA UCS', 'Oklab', 'hdr-CIELAB', 'hdr-IPT')], str]) – Colourspace model, see colour.COLOURSPACE_MODELS attribute for the list of supported colourspace models.

  • axis (Union[Literal[('+z', '+x', '+y')], str]) – Axis the hull section will be normal to.

  • origin (Floating) – Coordinate along axis at which to plot the hull section.

  • normalise (Boolean) – Whether to normalise axis to the extent of the hull along it.

  • section_colours (Optional[Union[ArrayLike, str]]) – Colours of the hull section, if section_colours is set to RGB, the colours will be computed according to the corresponding coordinates.

  • section_opacity (Floating) – Opacity of the hull section colours.

  • convert_kwargs (Optional[Dict]) – Keyword arguments for the colour.convert() definition.

  • samples (Integer) – Samples count on one axis when computing the hull section colours.

  • kwargs (Any) – {colour.plotting.artist(), colour.plotting.render()}, See the documentation of the previously listed definitions.

Returns

Current figure and axes.

Return type

tuple
