Right, if you're going to do it the pigment pattern way.

Stop thinking rocks, and think pigment, since that's the function that you're
passing on to the isosurface.  I'm not that great with the many pigment
functions - maybe there's something with turbulence, octaves, warp, etc.

I think that the spotted type patterns have that built in, as does the method of
creating separate visible rocks as part of one isosurface.   In other words - no
you don't, since it's already done.

I dunno.   I thought that only spheres and boxes could be used - but give it a
try and see what happens.
Though I think all that will do is "clip" out areas of the isosurface and not
give you the real _surface_, which is the whole point.

Also, See Mike Horvath's current "disappearing isosurface" thread - I think
evaluate would be an excellent feature to incorporate into all this.

and Tor's links to his scene which use his space-division method.
mod and select can be pretty cool when combined together like he does!
