mesh_conway_needle

compas.datastructures.mesh_conway_needle(mesh)[source]

Generates the needle mesh from a seed mesh.

Parameters

mesh (Mesh) – A seed mesh

Returns

mesh – The needle mesh.

Examples

>>> from compas.datastructures import Mesh
>>> mesh = Mesh.from_polyhedron(6)
>>> needle = mesh_conway_needle(mesh)
>>> needle.number_of_vertices() == mesh.number_of_vertices() + mesh.number_of_faces()
True
>>> needle.number_of_edges() == 3 * mesh.number_of_edges()
True
>>> needle.number_of_faces() == 2 * mesh.number_of_edges()
True
