To get the rpict parameters rad would produce use the options "-n -e"  
of rad
to have all the rendering steps printed to stdout. You can copy the  
necessary
rpict options to a file (ie. "rpict.opts") and include them in the  
rpiece
command line with "rpice ... @rpict.opts" (see the man page of rpiece  
for
details).
