pyFM.spectral.shape_difference.conformal_SD¶

pyFM.spectral.shape_difference.conformal_SD(FM, evals1, evals2)¶

Return the conformal shape difference operator computed from a functional map.

Parameters:

FM ((k2, k1) np.ndarray) – Functional map between two meshes.
evals1 ((k1,) np.ndarray) – Eigenvalues of the LBO on the source mesh (at least k1).
evals2 ((k2,) np.ndarray) – Eigenvalues of the LBO on the target mesh (at least k2).

Returns:

SD – Conformal shape difference operator.

Return type:

(k1, k1) np.ndarray
