You need to check the wiki entry under functions.inc

f_r(x,y,z): When used alone, the R function gives a surface that consists of all
the points that are a specific distance (threshold value) from the origin,

So basically you're just comparing your surface to a spherical shell.

At least you were able to work something out and get a decent result.
Isosurfaces can certainly be tricky, especially since we don't have vector
functions and certain inbuilt functions that other software packages pull from
libraries.

Chris R does everything with isosurfaces - maybe he can focus his highly trained
mind on it.

Agreed! I think, the only improvement is to close the surface by 
removing the open statement

Thanks, Michael, for the hint to remove 'open'.
I realised that there was still something wrong at the rim.

Your hint was the icing on the cake!
