mesh_adjacency_matrix

compas.datastructures.mesh_adjacency_matrix(mesh, rtype='array')[source]

Creates a vertex adjacency matrix from a Mesh datastructure.

Parameters

  • mesh (compas.datastructures.Mesh) – Instance of mesh.

  • rtype ({‘array’, ‘csc’, ‘csr’, ‘coo’, ‘list’}) – Format of the result.

Returns

array-like – Constructed adjacency matrix.

Examples

>>> from compas.datastructures import Mesh
>>> mesh = Mesh.from_polyhedron(6)
>>> A = mesh_adjacency_matrix(mesh)
>>> type(A)
<class 'numpy.ndarray'>

>>> A = mesh_adjacency_matrix(mesh, rtype='csr')
>>> type(A)
<class 'scipy.sparse.csr.csr_matrix'>
