Steve,

just a guess: if you evaluate

Options[ComputationalGeometry`Methods`ConvexHull3D]

you'll see a lot of options, perhaps some of the non-standard ones will
help you (if you figure out what they actually do). Mind you, nothing is
documented and more probably some kind of temporary precursor to future
stuff.

Regards,
Yves
