Well, those three sets of points ultimately still define only one hull. But I get your intuition—there are areas inside that hull that are high density, and areas that are much lower density (but in which it might be easier to extrapolate due to being surrounded by known areas). I feel like also our inability to visualize these things in their true dimensionality is probably really limiting. The real structures must be mind-boggling and probably looking more like some kind of fractal filament networks.
