I think if you could describe more of your problem domain, we might have better suggestions. Like, what do all of these geometries actually represent? I know you're trying to generalize the problem, but sometimes knowing the specifics of the problem allows us to make domain-specific suggestions.
Like, sometimes the question is "how do I make my axe cut faster" but the real answer is "here, use a chainsaw instead".
