Matt,
Can someone remind me why we need the strict and unstrict region objects? The strict ones select by cell center, the unstrict by any intersection. I seem to recall a concrete use case but I can't dredge it up.
If memory serves, it was such that particles are chosen strictly for the halo finders. Does that sound right?
So a better question, I suppose, is why do we have an *un*strict region? Should we be doing unstrict for all of our data objects? i.e., if a sphere intersects a cell but doesn't hit the corner, do we select that cell?
Additionally, if we are actually checking for periodicity, it seems to me we have no need for non-periodic regions, right? We just coalesce into a single rectangular prism object that, if appropriate for the simulation, wraps around?
Sounds good to me.
Cool. -Matt
