Unfortunately I do not have a point in the volume available. I am trying to make a custom radioactive source, where I can select the radioactive volume from all the volumes in my detector via command and then have decays occur in this volume. Everything is working except the translation of the random decay point in the volume -> world coordinates, and short of iterating over my entire detector with a stepsize of the smallest dimension of the smallest volume, I do not see a feasible way of locating a point in the volume. The only alternative I can think of would involve changes to the geant4 kernel. Is there no other option available?
