pyFM.mesh.geometry.per_vertex_normal_uniform

pyFM.mesh.geometry.per_vertex_normal_uniform(vertices, faces, face_normals=None)

Compute per-vertex normals of a triangular mesh, with uniform weights across adjacent faces.

Parameters:

• vertices ((n, 3) np.ndarray) – Coordinates of the mesh vertices.

• faces ((m, 3) np.ndarray) – Vertex indices defining the faces.

• face_normals ((m, 3) np.ndarray, optional) – Per-face normals. Computed from the mesh if not provided.

Returns:

vert_normals – Array of per-vertex normals.

Return type:

(n, 3) np.ndarray
