graphlow.core.MeshGeometry.face_normals

MeshGeometry.face_normals(eps: float = 1e-12) → T

Compute unit face normals.

Parameters:

epsfloat, default=1e-12

Numerical epsilon used for normalization.

Returns:

T

Backend tensor of shape (n_faces, 3) for volume meshes or (n_cells, 3) for surface meshes (each cell is a face).
