Hi Alex, I created the optional package with the goal of eventually enabling it as a backend for computing numerical Polyhedron objects. Currently we use cddlib, transitioning to the Parma Polyhedra Library (PPL). Both cddlib and PPL are more focused on exact computations, and I think Qhull will be superior for numeric work. However, I have not had time to write that interface.
Currently the best place to get a sense of the shared library functionality is in the file test_qhull.py, which is in $SAGE_ROOT/ local/lib/python2.6/site-packages/scipy/spatial/tests, at least in sage-4.7.alpha3. I believe the shared library was added in sage-4.7.alpha2 when scipy was upgraded, so you would have to have at least that version or higher. -Marshall Hampton On Apr 6, 6:42 pm, Alex Raichev <tortoise.s...@gmail.com> wrote: > Hi Doug: > > Qhull installs no problem on my Mac desktop.
