faceNormal

Callable

• faceNormal(a: Vec3, b: Vec3, c: Vec3): Vec3

---

• Compute the unit face normal for triangle (a, b, c) via cross product. Returns a normalized Vec3. Degenerate triangles produce a near-zero vector clamped to length NORMALIZE_EPSILON.

  Parameters

  • a: Vec3

  • b: Vec3

  • c: Vec3

  Returns Vec3
