Hi, I would like to perform some computation in
SteppingAction::UserSteppingAction(const G4Step* step) which involves the points of the trajectory of a particle.
Question 1: how can I get these points? My guess is:
but then I don’t know how to choose the trajectory of a particle of a current step among all the trajectories in the container.
Question 2: how can I get the materials at these points? I know the method via the step point and a touchable, but don’t know how to use it on a trajectory point:
Thanks in advance!
