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

Parameters:

  • hull (trimesh.Trimesh) – Trimesh hull.

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

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

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

  • contour_colours (ArrayLike | str | None) – Colours of the hull section contour, if contour_colours is set to RGB, the colours will be computed according to the corresponding coordinates.

  • contour_opacity (float) – Opacity of the hull section contour.

  • convert_kwargs (dict | None) – Keyword arguments for the colour.convert() definition.

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

Returns:

Current figure and axes.

Return type:

tuple
