Yes. Perhaps You, Tor or someother fan of functions will find simpler version
but it was simples I found. But all rounded versions are only slightly slower
than yours sharp shapes.

Yes, currently I have 3 file on my machine
iso_csg - your
iso_rcsg - rounded version
iso_bcsg - bounding layer

iso_bcsg doesn't contain #include of #iso_csg or #iso_bcsg so it works with
both (depending what was included by user)

I suppose. Internall codec works much faster than VM code as f_r() shows. But
I only affraid about characteristic outside of surface with threshold 0 - does
it saves linear distance ?

You can look into p.b.i at sample image.

Great.
