I need to create spiral images for spiral-carved table legs etc. I have
discovered that it can be done using the sphere sweep modification to
PovRay. I'm slightly wary though.

TMPov can do sphere sweeps but it is unsupported by the PovRay team. I can
get C code to compile my povray to use sphere sweeps, but there is a
problem.

No offence, but I don't want to wreck my current povray installation by
converting it to something which a) is unsupported, and b) I will lose next
time a version comes out....

To this end is there any way to create such objects without modifying
Povray, possibly via triangle-patchs properly modelled. I have SPatch, and
Moray, but though they both do rotational sweeps, neither of them consider
that a translation might be required.


Can anyone suggest some software to supply povray/moray with the object I'm
looking for, or if not, is there any way of faking it?

Yours hopefully,
