I like this ! Thank you for sharing Jaap.

It is interesting to see what "other"
things can be done with POV-Ray.

I have several times wondered if it
would be much work to model such
electron probability "clouds" for atoms.

And now I see that it's a LOT of work.


Btw: Are you aware of the built-in f_r()
function in functions.inc ?

You could replace your sqrt(x*x+y*y+z*z)
expressions with f_r(x, y, z)

I have also found that f_th() and f_ph()
are two other useful functions from this
include file.

Maybe you could use f_th(y, 0, z) and
f_th(z, 0, y) instead of your
CosInverse() and SinInverse() functions
(?)
