> I'm not sure if I could replicate this well enough to be useful - I am trying to construct
a PolyhedronsSet from a collection of Planes using RegionFactory.buildConvex(). The input
planes are created from running QHull - I don't have the actual normals but I can add them
to this report if I run into this again.
