You can give the periodic interval as an argument to the
macro. This makes it easy to study the periodicity when
the interval is set small.

Do you know where the 'far areas' are and how the functions
typically degenerates ?

Why is that ?

The macro can produce noise functions that behave simlar
to f_noise3d()
