---|
35 | // Decides which intermediate points on a curved trajectory merit |

36 | // being stored. Defines the compromise between accuracy of |

37 | // representation of the curved trajectory and memory use. |
---|
38 | // |
---|
39 | // Derived classes should implement the filtering algorithm in the |
---|
40 | // method TakeIntermediatePoint(). |
---|
41 | // |
---|
42 | // IMPORTANT: This class heap allocates vectors of auxiliary points, |
---|
43 | // which it does not delete. The vectors must find their way to a |
---|
44 | // subclass of G4VTrajectoryPoint, which must take responsibility for |
---|
45 | // deleting them. |
