Periodic wrapping for BVH

[fritzio]

Hi all,

I am experimenting with particle simulations, where particles have different interaction radii (spatially). Therefore, the HashGrid data structure is not the most suitable choice, but the BVH data structure seems more appropriate. If so, do you plan to add a periodic wrapping of neighboring particles similar to the HashGrid data structure, where if the particle interaction crosses the boundary, it still returns the periodically wrapped neighbors? If not, do you have any advice on how to do this easily in our application without the need to introduce mirrored ghost particles?

Thank you!
