delete_halfedge

Mesh.delete_halfedge(halfedge, del_isolated_verts=True)

Merge adjacent faces.

Merges the incident faces of an edge. Merging across a boundary edge will delete the incident non-boundary face. Vertices of halfedge rendered isolated by the change in mesh combinatorics can be kept as isolated vertices or be marked as deleted.

Parameters:

• halfedge (Halfedge) – The halfedge that spans the edge to be deleted.

• del_isolated_verts (bool, optional) – Mark isolated vertices for deletion.

Raises:

NonManifoldError – If the operation leads to invalid combinatorics.

Returns:

The merged face or None when merging across the boundary. For interior halfedge, this is equal to the face to its right.

Return type:

Face

Note

This operation may create dangling (half)edges, i.e., halfedges where h.pair equals h.next.
