mesh_slice_plane

compas.datastructures.mesh_slice_plane(mesh, plane)[source]

Slice a mesh with a plane and construct the resulting submeshes.

Parameters

  • mesh (Mesh) – The original mesh.

  • plane (Plane) – The cutting plane.

Returns

tuple[Mesh, Mesh] | None – The “positive” and “negative” submeshes. If the mesh and plane do not intersect, or if the intersection is degenerate (point or line), the function returns None.

Examples

>>> from compas.geometry import Plane
>>> from compas.geometry import Box
>>> from compas.datastructures import Mesh
>>> plane = Plane((0, 0, 0), (1, 0, 0))
>>> box = Box.from_width_height_depth(1, 1, 1)
>>> mesh = Mesh.from_shape(box)
>>> result = mesh_slice_plane(mesh, plane)
>>> len(result) == 2
True
