Is there a method to get a global position for a physical volume or path?
The closest thing I could find is this comment in the docs for TGeoMatrix:
The second use case is the computation
of the global transformation of a given object in the geometry. Since the
geometry is built as ‘volumes-inside-volumes’, this global transformation
represent the pile-up of all local transformations in the corresponding
But that’s merely suggestive, and not very practical. Isn’t there a class method somewhere to perform this operation? If not, is there a best-practices recipe for how to go about it?
I see that the inverse function (translating a location to a physical volume) seems to be fairly well supported in TGeoManager.
