iskra.directional.smooth_n_rosy(vertices: Tensor, faces: Tensor, flaps: Tensor, connection: Tensor, n: int, sources: int | Iterable[int] | Tensor, intrinsic: complex | Iterable[complex] | Tensor) → Tensor[SOURCE]

Smooths an N-RoSy field.

Parameters:

• vertices (Tensor[Float, [V, Dim]]) – Mesh vertices. Dim is either 2 or 3.

• faces (Tensor[Int64, [F, 3]]) – Triangle faces.

• flaps (Tensor[Int64, [E, 2]]) – Edge-to-face connectivity in the mesh. See edge_flaps().

• connection (Tensor[Complex, [E]]) – Discrete connection. You can use face_tangent_bundle() to obtain a connection from a mesh.

• n (int) – The degree of symmetry of the N-RoSy field. Is simply 1 for vector fields.

• sources (int | Iterable[int] | Tensor[Int64, […]]) – Array of indices of faces with hard constraints.

• intrinsic (complex | Tensor[Complex, […]]) – Array of complex N-RoSy coefficients to be transported. Use to_intrinsic_n_rosy() to project extrinsic vectors to intrinsic N-RoSy ones.

Returns:

​ (Tensor[Complex, [F]]) – Smoothed vectors.
