If I understand the Geant4 manual correctly, then tracking consists of steps. A step is defined by a start point (PreStepPoint) and a stop point (PostStepPoint). When I have a discrete processes, like Compton scattering, the PostStepPoint is defined by the smallest physical interaction length of these processes. This means if Compton scattering defines this smallest physical interaction length a Compton scattering happens at the PostStepPoint, correct?
Now in the most examples, which are included in G4, e.g. the GammaRayTel example, in the class GammaRayTelCalorimeterSD, ProcessHits(...), the position of a hit is set via:
l 129: CalorimeterHit->SetPos(aStep->GetPreStepPoint()->GetPosition());
Shouldn't it be set via GetPostStepPoint?? Do I misunderstand something?
