31 //
32 // This is a concrete class of G4VTrajectory which represents a trajectory of a ray.
33 // This class is used by G4RayTracer. Objects of this class are created by G4RTTrackingAction.
34 // This class does not have concrete implementations of draw and print methods but
35 // information stored in this class is used by determining a colour of a pixel of the picture.
