addEdgeNormal

Callable

• addEdgeNormal<K>(edgeNormals: Map<K, EdgeNormalEntry>, i0: number, i1: number, n: Vec3, makeKey: (lo: number, hi: number) => K): void

---

• Accumulate a face normal for the undirected edge (i0, i1).

  The caller supplies a makeKey function that turns the canonical (lo, hi) vertex-index pair into the map's key type.
