--------------( oo )--------------
Is there a way to do a "SWEEP along 3D PATHS" object in PovRay? I have a 3D
curve and I wich to obtain a TUBEPLOT like. I'm working on Mathematical
knots and I wich to extrude a 2D 'H' shape along a 3D path. Any solutions?

take a look at "6.5.1.10 Spheresweep" in the docs

Sphere Sweep Doesn't allow to do a defined shape extrusion. We could imagine
taking a rectangle instead of a Sphere. The Finale shape will looks
facetized instead being round. Most of common meshes modelers will handle
that for you. I saw an example that explain how tedious it could be when you
have to code every triangle. And I have to use CSG on.
Please, take a look at http://www.uib.no/People/nfytn/tknottxt.htm and
http://www.uib.no/People/nfytn/tknotgif.htm from Tore Nordstrand.
I didn't found any elegant way to do this without using commercial modelers.
Please, take a look at my project:

If you can use a 2d spline describe the cross section of the shape you
want to sweep with, then you can use the "Bent Prism" technique that I
describe here:

Maybe this one:

Or else I can mail you Daniele Varrazzo's Stricia, it does not seem to be
available on the web anymore

I'll see if I can track Daniele down and ask for his permission to post it
to this server.

Thanks Everyone for your alternatives on that operation. I'm currently in
contact with a french teacher that he have a different approach. I'll work
on that on the weeks to come. I'll have something to release in two weeks.
