32 // Class description:
33 //
34 // A class for use by the tracking management, able to obtain/calculate
35 // dynamic tracking time information such as the distance to the next volume,
36 // or to find the physical volume containing a given point in the world
37 // reference system. The navigator maintains a transformation history and
38 // other information to optimise the tracking time performance.

513 // NOTES:
514 //
515 // The following methods provide detailed information when a Step has
516 // arrived at a geometrical boundary. They distinguish between the different
517 // causes that can result in the track leaving its current volume.
518 //
519 // Four cases are possible:
520 //
521 // 1) The particle has reached a boundary of a daughter of the current volume:
522 // (this could cause the relocation to enter the daughter itself
523 // or a potential granddaughter or further descendant)
524 //
525 // 2) The particle has reached a boundary of the current
526 // volume, exiting into a mother (regardless the level
527 // at which it is located in the tree):
528 //
529 // 3) The particle has reached a boundary of the current
530 // volume, exiting into a volume which is not in its
531 // parental hierarchy:
532 //
533 // 4) The particle is not on a boundary between volumes:
534 // the function returns an exception, and the caller is
535 // reccomended to compare the G4touchables associated
536 // to the preStepPoint and postStepPoint to handle this case.
537 //
538 // G4bool EnteredDaughterVolume()
539 // G4bool IsExitNormalValid()
540 // G4ThreeVector GetLocalExitNormal()
541 //
542 // The expected usefulness of these methods is to allow the caller to
543 // determine how to compute the surface normal at the volume boundary. The two
544 // possibilities are to obtain the normal from:
545 //
546 // i) the solid associated with the volume of the initial point of the Step.
547 // This is valid for cases 2 and 3.
548 // (Note that the initial point is generally the PreStepPoint of a Step).
549 // or
550 //
551 // ii) the solid of the final point, ie of the volume after the relocation.
552 // This is valid for case 1.
553 // (Note that the final point is generally the PreStepPoint of a Step).
554 //
555 // This way the caller can always get a valid normal, pointing outside
556 // the solid for which it is computed, that can be used at his own
557 // discretion.
