|
|
// class description:
|
|
//
|
|
// Implementing the calculation of the intersection point with a boundary when
|
|
// PropagationInField is used. Derived from method LocateIntersectionPoint()
|
|
// from G4PropagatorInField, it is based on a linear method for finding the
|
|
// intersection point; the difference compared to G4MultiLevelLocator is that
|
|
// no 'depth' algorithm is used in case of slow progress for finding the
|
|
// intersection point.
|
|
|
|
// History:
|
|
// -------
|
|
// 27.10.08 - Tatiana Nikitina: Derived from LocateIntersectionPoint() from
|
|
// G4PropagatorInField class
