30 // Class G4SimpleLocator
31 //
32 // class description:
33 //
34 // Implementing the calculation of the intersection point with a boundary when
35 // PropagationInField is used. Derived from method LocateIntersectionPoint()
36 // from G4PropagatorInField, it is based on a linear method for finding the
37 // intersection point; the difference compared to G4MultiLevelLocator is that
38 // no 'depth' algorithm is used in case of slow progress for finding the
39 // intersection point.

43 // 27.10.08 - Tatiana Nikitina: Derived from LocateIntersectionPoint() from
44 // G4PropagatorInField class
