igl.local_basis(V, F, B1, B2, B3)

X2 = igl.rotate_vectors(X1, igl.eigen.MatrixXd.Constant(1, 1, pi / 2), B1, B2)

gradient_size = 50
iterations = 0
stiffness = 5.0

# Always work on the bisectors, it is more general
igl.compute_frame_field_bisectors(V, F, X1, X2, BIS1, BIS2)

# Comb the field, implicitly defining the seams
