__iter__

Mesh.__iter__()

Face iterator.

The returned iterator visits all faces of a mesh that are not marked as deleted in order of ascending face indices.

Yields:

Face – Next face in insertion order traversal.

The loop that visits all faces of a mesh that contribute to its combinatorics

for f in mesh:
    # do something with the face
    ...

is equivalent to explicitly checking the deleted attribute of a face:

for f in mesh.faces:
    if not f.deleted:
        # do something with the face
        ...
