Looks like it would simply be a couple of #while loops in POV, I'm just not
certain of the exact conversion for it.
You might consider reposting this to povray.general or the povray.advanced-users
group if you don't get any answers within a few days  ;-)

| Dear all,
|  I am quite new both to Rhino and POV-ray.
|  I'd like to see if I could convert Rhinolator (for Rhinoceros) script
| programs into the
| POV-ray program, which generates an interpolated curve similar to a
| greek letter, ohmega.
| From this line, I generate sweep_1_rail which has circular cross-section
|
|   ( Is this some sort of spline function in POV?).
| I wish I could use a sphere for the sweeping instead of the circle.
| However, this is the only method I know for the Rhinoceros programming.
|    One of the reason for trying to convert them is that the size of the
| final 'smoothed_triangle' data are
| quite big(somewhere around 50Mbyte when I duplicated the original
| ohmega-like lines) and time-consuming.
|   The other reason is that I would like to use either the
| sphere-sweeping_Catmull_Rom_Spline function of the Superpatch or the
| Blob function following the interpolated curve.
| From this I would like to make a semi-transparent solid wavy object.
| I am attaching some part of my Rhinolator script, which describes the
| curve part by part.
|
|   Thanks in advance,
|
