You do it letter-by-letter, translating and rotating as needed. For
instance, for letters on a circle of R radius in the xy plane, for the
letters on top, you would translate by y*R then rotate by z*letterAngle.
For letters on the bottom, you would translate by y*(R+letterHeight) and
then do the usual rotate.
This is easiest with MegaPOV, where you could use the min_extent() and
max_extent() functions to get the size of each letter, in the current
official version, you would have to position each letter manually, a big
pain even with fixed-width fonts.
It wouldn't be hard to make a macro to do this in MegaPOV, though. (I
think Ron Parker wrote a macro to do something similar, you could
probably modify it to do what you want. You could probably find it in
one of the scene file groups.)
