Dan,

First, see http://www.boost.org/community/groups.html#cplussig

Next, you'll want to write a custom type converter.  I'm sorry that it
isn't documented much.  You can read
https://realityforge.vrsource.org/view/PyOpenSG/HowBoostPythonWorks#Converting_from_python_to_c_and
which will teach you quite a lot but you might be better off asking on
the mailing list mentioned above if you just want a quick answer.

HTH,
