I'm using a sphere sweep for a cat5 cable (that blue ethernet cable
hanging out the back of your computer). Along a real cable is a text
designation declaring the cable to be cat5 (or 6). I want to include
that in my model. However the shere sweep is (surprise!) not a straight
line.
Is there any way to do this? What if the sweep was made up of many REAL
spheres or cylinders (each cylinder would be a lot smaller than the text
so I can't just put the text on every nth cylinder)
Any help, as usual, will be greatly appreciated.
Cheers!
Rick

I guess you need uv_mapping, but that's not currently available for
sphere sweeps. What you might be able to do is to use the SweepSpline
macro to produce a mesh that closely approximates the sphere sweep,
since uv_mapping is available for meshes.

I'm a newbie, but I would think that if you're able to do a cylindrical
image map and somehow use a spline for a path with it, it might work? just
an idea.

Why not cut text, made with the text object out of the side of the sphere
sweep.
You can use the Spline_Trans() macro from "transforms.inc" to position it
along a cubic spline, so as long as you use the cubic spline for your sphere
sweep too, then it should line all up.
I've put a sample source file on povray.binaries.scene-files and an image on
povray.binaries.images.
(see "Text on Sphere Sweep")
