XPLO2D generates 2D plot files from direct rot fun output
which can be contoured with O2D; both programs are on the
O ftp server & free for academics
for 3d pictures you could write a little jiffy to convert
the output into any map format & mappage with MAPMAN &
plot with O (note: x-lor 3d-matrix files can be read
directly into MAPMAN, so for normal rot/tra funcs this
is easy)
