suppose that you want to propagate optical photons through two consecutive volumes, that are put in contact each other (they belong to the same mother volume). In general I know that some issues can be caused by decimal precision loss in volume definition if you don't keep them slightly spaced. I think it's a quite common problem, but it's not clear to me how and if propagation of optical photon is affected by that.
I was wondering if in Geant4 there any options to set volume boundary crossing precision to say: "if two volumes are closer that X*mm then they really share a surface". In principle this could definitely avoid any problem with optical photon propagation between different volumes. Or Geant4 has a different approach for this kind of problems?
