Sorry about the last post, it got away from me...
Are you opposed to using a mesh2 instead of an isosurface?
It could be just me but I find the isosurfaces extremely hard to control
(and that is part of the beauty of POV-RAY)
The code may be more lengthly but I've found it parses much faster and it's
not as buggy.
I can post a mesh2 version of your function if you'd find it useful.
Thanks
Tony
