Thanks for the link and the idea.
Bending a cross section (defined by a spline) along a spline is exactly what
I need , but the render is too slow. I can't use it for my animation becaus
it takes too much of my time, not the computer's.
I see, looking for such a thing, fast AND good, is nearly impossible.
But I decided for the fast rendering, so I'm going to use the object bender.
