Polyhedral surfaces appear in a variety of discrete notions such as simplicial or cell
complexes, circle packings, or finite element meshes.
Although polyhedral surfaces often appear as discrete approximations of topological
two-manifolds this section focuses on their discrete properties.

As a guide, meshes should have no holes, no degenerate triangles and
elements, no duplicate vertices. Surfaces should have meshes with an adjacency
