Comment(by mikarm):
Hi Joris,
The "blow up" was caused apparently by a small mistake in
_create_pt_ode_system, see the comments in the parametric_surface3d.py.
Also this problem appears if the curve goes out the coordinate system (see
the worksheet parallel_translation).
Now I will try to do something on calculation of the principal curvatures.
Also, maybe I will manage to do the example of the surface you wrote
about.
Mikhail
