The closest thing you can come to proceeduraly, with Pov only,
would be by using a normal with a bump_map. The program Leveller
has a mesh output function that will wrap a height field around
a cylinder but it's limited to that shape only. There is another
older program called OrbCyl (dos) that will wrap a height field
around a sphere or a cylinder but again you are limited to the
specific surface shapes the program supports.

If you are really good at math you might try M3D. It will
allow you to create your own surface architecture with
out having to map it to an existing object.

Other than those I listed I think a bump map is abuot the easiest
approach but even that has it's limitations.
