I would personnally go for the ODE integrator in scipy, unless I want
something really efficient and that does the interpolation of the vector
field right, in which case I would dig in to reuse the Runge-Kutta engine
behind the Mayavi function that I linked to. Unfortunately, it is in VTK,
so using it requires quite a lot of work.
