yes, nviz has already the interface part for it - it should call r3.showdspf
(which does not work completely either as it does not do the "walls", boxes
and fences) and display the isosurfaces, crossections and other type of volume
stuff along with multiple surfaces, vectors and sites. That is what sg4d did.
For whatever reason Bill could not finish it for nviz. There is a lot of stuff
that we have prototyped
for GRASS5 which is not being released as there is a long way from a prototype
to releasable code.
Quite a bit of work for years ahead.
