Mesh3gs.face_adjacency_halfedge

Mesh3gs.face_adjacency_halfedge(f1, f2)

Find one half-edge over which two faces are adjacent.

Parameters

  • f1 (hashable) – The identifier of the first face.

  • f2 (hashable) – The identifier of the second face.

Returns

  • tuple – The half-edge separating face 1 from face 2.

  • None – If the faces are not adjacent.

Notes

For use in form-finding algorithms, that rely on form-force duality information, further checks relating to the orientation of the corresponding are required.
