0028 // Class description:
0029 //
0030 // Decides which intermediate points on a curved trajectory merit
0031 // being stored. Defines the compromise between accuracy of
0032 // representation of the curved trajectory and memory use.
0033 //
0034 // Derived classes should implement the filtering algorithm in the
0035 // method TakeIntermediatePoint().
0036 //
0037 // IMPORTANT: This class heap allocates vectors of auxiliary points,
0038 // which it does not delete. The vectors must find their way to a
0039 // subclass of G4VTrajectoryPoint, which must take responsibility for
0040 // deleting them.
