Question Descending volume tree 

Forum: Geometry
Date: 19 Jun, 2009
From: Kevin Sapp <Kevin Sapp>

Hi GEANT wizards,
I have been looking for a way to access a GEANT4 geometry and determine its tree structure with two important criteria:

1) I must be able to descend from one volume to all its daughters, and
2) I must be able to access each touchable element independently.

Is this going to be possible? I've looked into the geometry navigation tools as much as possible, and it seems if I navigate by daughter volumes I lose (2), while if I navigate by touchables I lose (1), and while I can move from touchable to physical volume, there isn't a way to go from physical volume to touchable (I understand that the physical volume information itself wouldn't be enough, but it seems that including GetCopyNumber information should allow this). Anyone have any suggestions?
