A look at implimentation by
Bueler, Enge, Fukuda, and Luthi, available from ETH Zurich:
        ftp://ftp.ifor.math.ethz.ch/pub/volume/
might help.

In addition to source code, the directory includes a PostScript
description of several algorithms and some experimental results.  Not
surprisingly, they find that different algorithms are more efficient for
different polytopes.
