I have now made a couple of rendering of this function with both the natural
logarithm and the base 10 logarithm of the magnitude.

It looks like your rendering was done with the base 10 logarithm. The attached
rendering was done with the natural logarithm.

It seems to me that using a logarithmic scale can sometimes reveal some extra
information also in 3D.
