An optical photon is on the border between glass and vacuum, i.e. preStepPoint is in the glass and postStepPoint is in the vacuum. Via a created process, I move the postStepPoint back to the glass (position, momentum and time are changed).
If I look at the step information, everything works fine... new momentum, new position and new time are the ones I wanted for the output photon. But before this output, I have a null size step in the glass (where I moved the photon) which is, I guess, needed by the manager to change the volume of the postStepPoint from vacuum to glass (actually the only thing changing in this step is the volume: from vacuum to glass, the rest has the output photon characteristics).
I would like to know if this change of volume has any influence on the photon characteristics. More generally, I would like to know if you can move freely a particle from one volume to another one.
Thanks a lot,
