colour.geometry.hull_section#
- colour.geometry.hull_section(hull: trimesh.Trimesh, axis: Literal['+z', '+x', '+y'] | str = '+z', origin: Floating = 0.5, normalise: Boolean = False) NDArray [source]#
Compute the hull section for given axis at given origin.
- Parameters:
hull (trimesh.Trimesh) – Trimesh hull.
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.
- Returns:
Hull section vertices.
- Return type:
