None About volume boundary crossing precision 

Forum: Processes Involving Optical Photons

Hi,

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?

Thank you.

Michele.
