I've decided it's time to write an article on this topic,
since I have reason to understand it better myself. But,
do you find the IDL documentation of these three routines
particularly abstruse? In the QHULL documentation there
is no indication which of the arguments are input and which
are output, which set properties verses return information,
etc. In the words of one of my favorite expressions from
across the pond, it's a "pig's breakfast". :-(

Cheers,

David
