Yes, with a little work. There is an answer with a bit of
source code in an earlier answer at:
http://www.unidata.ucar.edu/staff/russ/visad/msg00488.html
Basically, you call resample() on your volume FlatField using
an argument Set with domain dimension = 3 and manifold
dimension = 2, and then display the FlatField returned by
resample().
Cheers,
Bill
