• A graph representation of the lattice, where polygons are nodes and adjacent when sides share a segment, with attributes for edge length and angle between faces.
• An efficient function to generate triangles and uv normals for a set of coplanar points forming a polygon (including non-convex polygons).
• An edge-coloring function by distance equivalence classes.
• An edge-coloring function by ditsance and equivalence classes.
