Interesting, do you know if these shapes can be converted in an implicit
form, at least in some special cases?

This would make it easier to render them in POV-Ray without generating a
mesh.

I don't think so.  When having many parameters it might be useful to group
them into vectors, this would be easier to memorize for the user.  If you
have vector parameters it is a good idea to alternatively allow floats by
using:

#macro Test (Parameter, ...)

  #local Param_Intern=Parameter+<0,0,0>;
