Gathering the one-ring of vertices from quads surrounding a vertex: - the neighborhood of the vertex is assumed to be quad-regular (manifold) Orderin

After the conditions for dependent sharpness have been confirmed, retrieve the desired value. The result is the maximum sharpness of interior edges t

Higher-level topological queries, i.e. values in a neighborhood: - given an edge, return values corresponding to its vertices within a given face - gi

Methods to retrieve and combine value and vertex tags:

Queries per vertex (and its potential sibling values):

Queries per value:

Values tagged as creases have their two "end values" identified relative to the incident faces of the vertex for compact storage and quick retrieval.

Two face-varying subsets are said to have "dependent sharpness" when the sharpness of one influences the other. This is applied when one subset has no

If more than two distinct face-varying subsets are present, the corner is sharpened regardless of any other conditions -- leaving cases of only one or
