36
37May 5th, 2009 - T.Nikitina (geomnav-V09-02-02)
38--------------------------
39- Fix in G4Navigator::ComputeStep() for the computation of rotation of the

41  for optical photons in rotated solids. Addresses problem report #1059.
42
43February 26th, 2009 - T.Nikitina (geomnav-V09-02-01)
44--------------------------------
45- Fixed problem in G4BrentLocator::EstimateIntersectionPoint() responsible

48January 27th, 2009 - G.Cosmo (geomnav-V09-02-00)
49----------------------------
50- Added G4RegularNavigationHelper class, used by G4RegularNavigation for
51  counting the number of step lengths in each voxel of the regular structure
52  (by P.Arce).

54
55December 11th, 2008 - T.Nikitina (geomnav-V09-01-10)
56--------------------------------
57- Reinstated G4MultiLevelLocator as the default locator to allow for proper
58  tuning of parameters in propagation in field and avoid CPU penalty currently
59  induced by default parameters.
60- Corrected text in exceptions in locators classes.
61
62November 14th, 2008 - T.Nikitina, J.Apostolakis (geomnav-V09-01-09)

66  solid to boost accuracy. Added the optional call to the new method in each
67  concrete locator.
68- Removed unnecessary accessors for Brent locator in G4PropagatorInField.
69- G4VoxelNavigation: implemented additional check when running in "check"
70  mode; if it is on the surface, ensure that it can move on next step;
71  either DistanceToIn(p,v) or DistanceToOut(p,v) should return a finite
72  value greater than the tolerance.
73
74November 10th, 2008 - G.Cosmo (geomnav-V09-01-08)
75-----------------------------
76- G4PathFinder: cleared unecessary calls to ComputeSafety() in ReLocate().

84  G4MultiLevelLocator. 
85- Coworks with tag "field-V09-01-03".
86
87October 10th, 2008 - G.Cosmo (geomnav-V09-01-06)
88----------------------------
89- Introduced optional Boolean argument in G4Navigator::ComputeSafety() to
90  allow for computation of safety without modifying the state restoring of
91  the navigator.
92- Modified accordingly the following classes, for calls to ComputeSafety():
93  G4SafetyHelper, G4PathFinder (now calling ComputeSafety() with TRUE
94  argument to preserve navigator's state), G4MultiNavigator and
95  G4ErrorPropagationNavigator.
96
97May 5th, 2008 - T.Nikitina (geomnav-V09-01-05)
98--------------------------

100  The Brent method is now used as default and can be switched off through
101  call to the proper accessor function SetBrentMethod().
102- Requires related update to G4ChordFinder in geometry/magneticfield module
103  included in tag "field-V09-01-02".

121-------------------------------
122- G4PropagatorInField: changed condition for 'ReEstimationEndPoint'
123  in order to better handle very strict parameters of propagation.
124  Also added more verbosity in case of error for negative step.
125  Fixes rare problem observed in production by ATLAS.
126

218
219September 25th, 2007 - G.Cosmo (geomnav-V09-00-02)
220------------------------------
221- Some code cleanup in G4PathFinder. Switch off additional optimisation
222  for safety in method DoNextLinearStep().
223- Set 'fRecomputeFactor' in G4SafetyHelper to 0.0, to switch off internal

225
226July 12th, 2007 - J.Apostolakis (geomnav-V09-00-01)
227-------------------------------
228- Restores fixes/improvements of geomnav-V08-03-07

233-------------------------------
234- G4PathFinder:
235  o Include correction to signature of method PrepareNewTrack().
236    (This was done on a branch for this class in order to keep only
237     development of geomnav-V08-03-06)

242
243July 5th, 2007 - G.Cosmo
244------------------------
245- G4PathFinder:
246  o Corrected signature to method PrepareNewTrack().
247    Resolves linking problems detected on SUN-CC platform.
248- Changes included in tag  "geomnav-V08-03-02c", included in relase 9.0.p01.
249
250June 8th, 2007 - T.Nikitina
251---------------------------
252- G4PropagatorInField:
253  o Put in the constructor creation of array of FieldTracks used in
254    LocateInterSectionPoint().
255  o Change in ReEstimateNewPoint() in order to handle cases with zero step
256    caused by diffCurve=0.
257  o In case of proposed step less than tolerance, now return 'kInfinity'
258    as per convention of geometry instead of 'DBL_MAX'.
259    (by J.Apostolakis, May 18th 2007)
260- Changes included in tag "geomnav-V08-03-02b", included in release 9.0.
261
262June 5th, 2007 - J.Apostolakis (geomnav-V08-03-07)
263------------------------------
264- G4PathFinder:
265  o New method to return the safety sphere last calculated for
266    a PreStep point (it could be a previous one - due to optimasation).
267    >> If last step(s) were smaller than safety, then for a linear
268    track (no field or no charge) Navigator's ComputeSafety is not
269    called.  The older PreStep (previous step or some steps back
270    in case of many small steps) is stored for this - and provided.
271  o ComputeStep() still returns current PreStep point's safety (must).
272  o Revisions are to make this (used by CoupledTransportation) more
273    compatible with the old direct use of G4Navigator by G4Transportation.
274
275May 29th, 2007 - J.Apostolakis (geomnav-V08-03-06)   
276------------------------------
277- G4Navigator
278  o Fixed **ComputeSafety**: wrong coordinates used (last tag only).
279    For certainty reinstated LocateGlobalPointWithinVolume (for now).
280  o Corrected calculation of fStepEndPoint (in ComputeStep)
281    for case of step not limited by geometry
282- G4PathFinder
283  o PrepareNewTrack: calls to re-initialise SafetyHelper (reset safety)
284  o ReLocate: Corrected check of move (avoid one side effect on stored safety)
285              --> ComputeSafety still results individual navigators' values.
286
287May 24th, 2007 - J.Apostolakis (geomnav-V08-03-05)
288------------------------------
289- G4PathFinder: 1 correction and 2 optimisations:
290  o PrepareNewTrack() clear safety - to avoid potential problems in overlaps.
291  o DoNextLinearStep() only calls ComputeStep() for a navigator whose safety
292    greater than the step.
293  o DoNextCurvedStep(), if there's one geometry, no longer calls
294    ComputeSafety() at start.
295- G4Navigator ComputeSafety:
296  o Corrected it to address use at non-endpoint
297  o Replaced call to LocateGlobalPointWithinVolume() with calls to
298    sub-navigators.
299
300May 21st, 2007 - G.Cosmo
301------------------------
302- Made 'fVerbose' protected in G4Navigator, reused in G4MultipleNavigator.

306  class (by P.Arce).
307
308May 19th, 2007 - J.Apostolakis (geomnav-V08-03-04)
309------------------------------
310- Corrections and additions in G4PathFinder:
311    1) Added calculation of start-point safety in DoNextCurvedStep
312    2) Corrected GetCurrentSafety() - uses mininum of 1)
313    3) Added method to obtain safety of one navigator (after call to all).
314    4) Deleted obsolete data member 'fMinSafety'.
315    5) If only one geometry, do not call WhichLimited in DoNextLinearStep (optimisation)
316    6) ComputeSafety: save the values of isotropic safety for each navigator
317
318May 18th, 2007 - A.Howard (geomnav-V08-03-03)
319------------------------
320- Fixed return value for G4PathFinder::ComputeStep in case of
321   step smaller than tolerance (now kInfinity): fixes one PathFinder issue (JA).

333  for performing double navigation in the detector geometry and on the
334  target surface for error propagation (by P.Arce).
335- Fixed bug in G4GeomTestSegment in case of TestPoint on the surface,
336  reducing cases of reported spurious overlaps.
337- Coworks with tag "global-V08-03-02".
338
339May 16th, 2007 - J.Apostolakis (geomnav-V08-03-00a)
340------------------------------
341- Moved to G4PathFinder version without extra prints
342
343April 26th, 2007 - G.Cosmo (geomnav-V08-03-00)
344--------------------------
345- Use call to G4GeometryTolerance instead of kCarTolerance where needed.
346- Revised data members in G4SafetyHelper to conform to convention.
347- Requires tag "global-V08-03-00" and related tag set.
348

357- Some cleanup and minor cosmetics ...
358
359April 12st, 2007 - V.Ivanchenko
360-------------------------------
361- G4SafetyHelper become a unique class, which can be accessed via
362  G4TransporationManager. Depending on type of navigation (single
363  world or multiple navigation) it uses mass navigator or G4PathFinder.
364  All calls from EM processes to geometry are provided by G4SafetyHelper.
365- G4TransportationManager: added G4SafetyHelper.
366- G4PathFinder: initialisation of G4SafetyHelper.
367- Tagged "geomnav-V08-02-02-beta2".
368
369March 31st, 2007 - J. Apostolakis
370---------------------------------
371- G4Navigator:
372  o New method CheckNextStep() makes a trial step, without
373    changing the state of the Navigator (to be verified).
374    It is a variant of ComputeStep, whose signature it shares.
375- Tagged "geomnav-V08-02-02-beta1".
376
377February 13th, 2007 - J.Apostolakis
378-----------------------------------
379- G4Navigator:
380  o Improvement for creating touchable history when located outside world.
381    Retain whether last point was located outside, and if so call default
382    TouchableHistory constructor (that initialised world to null).
383    NOTE: testing found problems with SteppingManager::SetInitialStep()
384          as the Vertex physical volume was not set. Protection is potentially
385          required, or bigger issue to be resolved.
386    Currently, changes in G4Navigator.hh,cc are safe, but the fix in .icc is
387    temporarly suspended and NOT included.
388- Attempted fix created Dec 7th, 2006
389
390February 13th, 2007 - J.Apostolakis (geomnav-V08-02-01)
391-----------------------------------
392- G4PropagatorInField:
393  o Implemented ClearPropagatorState() to clear all the track-dependent
394    state (incl. safety, zero-steps, loop flag ...).
395    ** Calling this is mandatory for each new track because in the case of
396       geometry overlaps, the safety can be easily inconsistent (and/or
397       incorrect) otherwise
398    ** Must be called from G4Transportation (or alternatives) !!
399- Fix created Jan 25th, 2007
400
401January 31st, 2007 - G.Cosmo (geomnav-V08-02-00)
402----------------------------
403- G4Navigator: forcing call to CheckOverlaps() on the current volume
404  before event abortion for cases of stuck tracks.
405- Requires tag "geommng-V08-02-00".
406
407November 23rd, 2006 - J.Apostolakis (geomnav-V08-01-08)
408-----------------------------------
409- G4PathFinder:
410  o Fix when report a problem only if move > safety (additional check).
411  o Revised condition for extra checking against safety.
412  o Many small and cosmetic changes in debug printing.
413
414November 18th, 2006 - J.Apostolakis (geomnav-V08-01-07)
415-----------------------------------
416- G4PathFinder:
417  o Fix for problem when step is fully taken.
418    Note: this occurs due to optimisation in PiF that avoids calling
419    G4(Multi)Navigator!!
420  o Function LimitedString( ELimited lim ) enables printing this enum
421  o Improved printing in IntersectChord. Deleted/simplified few prints in
422    ComputeStep().
423- G4MultiNavigator: cleanup, cosmetics
424
425November 13th, 2006 - G.Cosmo (geomnav-V08-01-06)

434- G4MultiNavigator:
435  o Several fixes, primarily for taking care of condition of
436    geometry limited step.
437
438November 11th, 2006 - J.Apostolakis (geomnav-V08-01-04)
439-----------------------------------
440- G4PropagatorInField:
441  o Refined fix in LocateIntersectionPoint(), to subdivide
442    in case it cannot find intersection point quickly (T.Nikitina).
443    Second version, with several levels of cutting.
444  o NOTE: Special tags made (later) not including the Developments in
445    G4TransportationManager, G4PathFinder, G4SafetyHelper for parallel
446    navigation. i.e. - based on tag "geomnav-V08-01-03".
447

449-----------------------------------
450- Created G4MultiNavigator class and utilised it from G4PathFinder
451  to implement curved trajectory parallel navigation.
452
453November 10th, 2006 - J.Apostolakis (geomnav-V08-01-03)
454-----------------------------------
455- G4PropagatorInField:
456  o Fix in LocateIntersectionPoint(), to subdivide in case it cannot find
457    intersection point quickly (T.Nikitina).
458    First version, only one level of cutting
459  o NOTE: Special tags made (later) not including the Developments in
460    G4TransportationManager, G4PathFinder, G4SafetyHelper for parallel
461    navigation. i.e. - based on tag "geomnav-V08-01-02".
462
463November  9th, 2006 - J.Apostolakis
464-----------------------------------
465- G4SafetyHelper:
466  o Changed default value of 'fUseParallelGeometries' to 'false'.
467    This is the default, except when using parallel geometries.
468    Value 'true' will become the default.
469
470November 4th, 2006 - M.Asai
471---------------------------
472- G4TransportationManager:
473  o added new method SetWorldForTracking() to enable change of world from
474    the RunManager.
475
476October 31st, 2006 - J.Apostolakis
477----------------------------------
478- G4SafetyHelper
479  o Added new class variable 'fUseParallelGeometries', to enable
480    it to work call G4Navigator of Mass geometry directly, in
481    the case of single geometry (when G4PathFinder is disabled).
482  o Default value is currently 'true' --> for parallel navigation development.
483- G4PathFinder
484  o Improved the code that checks within relocation whether position
485    is proposed to be moved outside safety sphere from endpoint.
486
487October 26th, 2006 - G.Cosmo (geomnav-V08-01-02)
488----------------------------
489- G4Navigator:
490  o Added inline methods EnteredDaughterVolume() and ExitedMotherVolume() to
491    allow for verification of a point entering a daughter volume or exiting
492    the mother volume.
493  o Made LocateGlobalPointAndSetup() method virtual. Moved to non virtual
494    and inline LocateGlobalPointAndUpdateTouchableHandle() method.
495  o Moved 'fHistory' data member to protected to aloow for more complete
496    subclassing.
497  o Minor cosmetics to recently introduced printout diagnostics in
498    ComputeSafety() method.
499- G4TransportationManager:
500  o Added methods to access the list of the registered worlds.
501- NOTE: this tag does NOT include the recent developments introduced for
502  G4PathFinder. It resumes from tag "geomnav-V08-00-01"; anything else
503  introduced after it, except for changes in G4Navigator, is NOT included !
504
505October 25th, 2006 - J.Apostolakis
506----------------------------------
507- G4PathFinder: fixed initialisation of cached value for the
508  G4TransportationManager to cope with singletons.
509
510October 16th, 2006 - J.Apostolakis    (geomnav-V08-01-01)
511----------------------------------
512- G4Navigator: moved debug printing behind fVerbose conditions
513
514October 12th, 2006 - J.Apostolakis (geomnav-V08-01-00)
515----------------------------------
516- New class G4SafetyHelper to aid multiple scattering inn
517  determining the correct Mass geometry step (via PathFinder)
518  and all-geometry safety.
519- Several revisions, fixes to G4PathFinder.
520
521June 8th, 2006 - J.Apostolakis (geomnav-V08-00-06)
522------------------------------
523- G4PathFinder:
524  o New method 'ComputeSafety' to compute safety at endpoint of last step.
525
526June 2nd, 2006 - J.Apostolakis (geomnav-V08-00-05)
527------------------------------
528- G4PathFinder:
529  o New method ReLocate() for non-Transportation classes to call when moving
530    the endpoint of a particle. Uses LocateGlobalPointWithinVolume() method
531    of the navigators.
532  o Small fixes and protection of debug printing with Verbose flag.
533  o Default verbose level is now 0.
534
535May 28th, 2006 - J.Apostolakis (geomnav-V08-00-04)
536------------------------------
537- G4PathFinder:
538  o Check whether a process shifted the position since the last step.
539  o Corrected checking for 'Unique', i.e. one process limiting step.
540  o Revised printing (more information, some protected by verbose flag).
541
542May 27th, 2006 - J.Apostolakis (geomnav-V08-00-03)
543------------------------------
544- G4PathFinder revised significantly:
545  o Workaround for problem of CreateHistory() when outside world.
546  o Revised for new counting of Navigator IDs (M.Asai).
547  o Added MovePoint() method that signals if it moved.
548  o Added state to cope with cases where a full step is taken,
549    i.e. to cope with steps that return kInfinity:
550    New state:
551      RelocatedPoint - to show if it is moved;
552      TrueMinStep    - finite whereas reported can be kInfinity.
553    and to aid in clarifying the state of the (singleton) object:
554      LastStepNo     - already kept in one method (static), now exposed;
555      CurrentStepNo  - mostly for debugging and printing out.
556  o Small improvements in tests.
557
558May 23rd, 2006 - J.Apostolakis (geomnav-V08-00-02)
559------------------------------
560- Added new prototype class G4PathFinder to coupled navigation
561  in parallel geometries.
562
563May 22nd, 2006 - G.Cosmo (geomnav-V08-00-01)
564------------------------
565- Extended G4TransportationManager to handle multiple navigators.
566  Preserved interface for navigation in mass/tracking geometry.
567- Added activation flag to G4Navigator and related accessor methods.
568
569Feb 8th, 2006 - J.Apostolakis (geomnav-V08-00-00)
570-----------------------------
571- Addressing problem with convergence in LocateIntersectionPoint()
572  of G4PropagatorInField (problem identified by Atlas, observed when
573  requesting high precision, i.e. small values of eps_min/max, delta_one_step,
574  due e.g. to need for small delta_intersection):
575  o First solution by increasing maximum iterations (from 100 to 10,000).
576  o Until correct information can be returned, an Exception is thrown
577    in case of too many iterations.
578  o Warn in case over 1000 iterations, to let user see difficulty.
579- This fix is an interim solution, in lieu of improving the algorithm
580  for location (or returning correct incomplete progress).
581
582Nov 24th, 2005 - J.Apostolakis (geomnav-V07-01-02)
583------------------------------
584- Revised G4ParameterisedNavigation, to use new interface for
585  ComputeMaterial(). Now no longer needing 'Physical Touchable'.
586
587Sep 19th, 2005 - G.Cosmo  (geomnav-V07-01-01)
588------------------------
589- G4DrawVoxels: removed unnecessary 'panic' message in ComputeVoxelPolyhedra()

625
626Sep 13th, 2004 - G.Cosmo  (geomnav-V06-02-03)
627------------------------
628- G4Navigator: corrected computation of fGrandMotherExitNormal in ComputeStep()
629  in the case where a not valid exit-normal exists.
630
631Sep 11th, 2004 - G.Cosmo  (geomnav-V06-02-02)
632------------------------
633- Dump out contents from the solid when a fatal G4Exception is thrown from
634  the navigators in ComputeStep().
635  Modified files G4NormalNavigation.cc, G4ParameterisedNavigation.cc,
636                 G4ReplicaNavigation.cc, G4VoxelNavigation.cc.
637
638Aug 31st, 2004 - D.C.Williams  (geomnav-V06-02-01)
639-----------------------------
640- G4GeomTestSegment: fix to correctly determine whether starting trajectory
641  is entering or exiting the solid when the starting point is on a surface.
642  Added additional tests on solid consistencies (from roundoff sometimes) to
643  avoid incorrect overlap warnings. Addresses problem reports #610 and #652.
644
645Jun 29th, 2004 - G.Cosmo  (geomnav-V06-02-00)
646------------------------
647- Fixed zero step-length problem in G4ReplicaNavigation::ComputeStep()
648  for cases where different replica types are coincident. Resolves
649  problem report #633.
650- G4NormalNavigation: added extra verbosity to print out information
651  for each solid which returns a 'lowest-yet' step, including the
652  mother volume. It is activated by setting verbose level to 2 or
653  more (J.Apostolakis).
654
655Jun 18th, 2004 - G.Cosmo  (geomnav-V06-01-03)
656------------------------
657- Enhanced check for null step in G4Navigator::ComputeStep().
658  Now attempting a corrective action after 10 consecutive zero steps.
659  Event gets aborted after 25 zero steps.
660
661Jun 15th, 2004 - G.Cosmo  (geomnav-V06-01-02)
662------------------------
663- Relax exception in G4Navigator::ComputeStep() for stuck tracks.
664  Event gets aborted after 25 zero steps.
665
666Jun 11th, 2004 - G.Cosmo  (geomnav-V06-01-01)
667------------------------
668- Added check to G4Navigator to count the number of steps with zero length
669  and issue an exception for tracks that get stuck in a loop (J.Apostolakis).
670- Modified GNUmakefile to define G4GEOMETRY_ALLOC_EXPORT flag for DLLs
671  build on Windows.
672
673May 17th, 2004 - G.Cosmo  (geomnav-V06-01-00)
674------------------------
675- Added more verbosity on solids response for navigators (optimised/not
676  optimised) if "check_mode" state is combined with verbose level-1.
677
678Mar 11th, 2004 - G.Cosmo  (geomnav-V06-00-02)
679------------------------
680- Added "check_mode" state for navigators. The state can be activated by
681  a new UI command (geometry/navigator/check_mode [true/false]) and will
682  force more strict and less tolerant checks in step/safety computation to
683  verify the correctness of solids' response in the geometry.
684- Reorganised verbosity levels. Added more useful information activated
685  when in G4VERBOSE mode and verbosity level selected.
686  Fixed output formatting when entering/exiting verbose blocks.
687
688Feb 27th, 2004 - G.Cosmo  (geomnav-V06-00-01)
689------------------------
690- G4Navigator.cc:
691  o Fixed old outstanding bug in ComputeStep() for the location of the
692    the local point in the calculation of a valid exit normal. (V.Grichine)
693
694Feb  9th, 2004 - J.Apostolakis  (geomnav-V06-00-00)
695------------------------------
696- G4PropagatorInField.cc:
697  o ReEstimateEndpoint:  Changed to cope with a failure of AccurateAdvance,
698                         by calling it iteratively up maximum 20 times.
699  o SetVerboseLevel, now forwards the verbosity (minus 3) to integration driver
700
701Dec 11th, 2003 - J.Apostolakis  (geomnav-V05-02-15)
702------------------------------
703- G4PropagatorInField.cc:
704  o LocateIntersectionPoint: Refined re-setting of finalSection.
705    --> Endpoint recalculation is returned only for final section.
706    (trial fix in -14 is replaced by above code)
707  o Fixed ReEstimateEndPoint which ignored return code of AccurateAdvance
708    and moved to short end-point for long requests
709    It now leaves the endpoint unchanged, when it cannot improve it.
710  o Few format changes for PrintStatus
711
712Dec 10th, 2003 - J.Apostolakis  (geomnav-V05-02-14)
713------------------------------
714- G4PropagatorInField.cc on top of latest (not 1.7):
715  o Fix for the case where two previous corrections are 'operational'
716     Problem if the current endpoint is not the final one, and it has been
717     recalculated, and we need to go beyond the current section to the
718     final one -- the recalcuted endpoint no longer valid!
719
720Dec 10th, 2003 - J.Apostolakis  (geomnav-V05-02-13)
721------------------------------
722- G4PropagatorInField.cc:
723  o Gone back to version 1.7, without the fix in LocateIntersectionPoint
724      for the "long-standing error".
725
726Dec  5th, 2003 - G.Cosmo - (geomnav-V05-02-12)
727------------------------
728- G4TransportationManager.cc:
729  o removed initialisation of allocators for navigation levels, where they
730    were introduced as workaround for solving static initialisation a long
731    time ago. Now moved to "volumes" module, where they should belong, in
732    G4TouchableHistory.cc.
733- Restored original unit-tests, using inherited navigator.
734  --> Requires geomvol-V05-02-08
735 
736Dec  4th, 2003 - J.Apostolakis  (geomnav-V05-02-11)
737------------------------------
738- G4PropagatorInField.cc
739  o Corrected placement of #endif for two #ifdef VERBOSE
740
741Dec  2nd, 2003 - J.Apostolakis  (geomnav-V05-02-10)
742------------------------------
743- G4PropagatorInField[.hh.cc]:
744   o Fixed LocateIntersectionPoint for long-standing error.
745     A section of the chord was not considered in use case where
746     a previous chord at first appeared to have an intersection, but did not.
747
748Nov 26th, 2003 - J.Apostolakis  (geomnav-V05-02-09)
749------------------------------
750- G4PropagatorInField[.hh.cc]:
751  o Added argument Method LocateIntersectionPoint G4bool& recalculatedEndPt
752    to return 'true' if the endpoint has been recalculated.
753    This fixes a problem that can occasionally cause the skipping of a volume
754    boundary - in the case when a re-integration was done near a boundary,
755    because the new endpoint was previously not passed back.
756  o ComputeStep also changed to accept above recalculation.
757  o New method GetVerboseLevel(),  closer to std naming than Verbose()
758
759Nov 14th, 2003 - J.Apostolakis  (geomnav-V05-02-08)
760------------------------------
761- Retagged the files of tag "geomnav-V05-02-07", due to tagging with same
762  name incorrectly files in another directory and, as such confusing Bonsai.
763
764Nov 13th, 2003 - J.Apostolakis  (geomnav-V05-02-07)

776  o Renamed method LocateGlobalPointAndSetup(p,v,history) to
777    ResetHistoryAndLocate(p,v,history).
778  o Moved to protected the following methods: GetCurrentLocalCoordinate(),
779    ComputeLocalPoint(), ComputeLocalAxis(), NetTranslation(),
780    NetRotation(), EnteredDaughterVolume().
781  o Fixed consistency of inline/not-inline implementations of methods.
782- Coworks with tag "tracking-V05-02-03".
783
784Nov 6th, 2003 - J.Apostolakis  (geomnav-V05-02-05)
785-----------------------------
786- G4PropagatorInField[.hh.icc.cc]:
787  o Implements move of EpsilonMin / Max to G4FieldManager.
788- Requires and coworks with "field-V05-02-04" or later tag.

791-----------------------
792- G4Navigator[.hh.icc.cc]:
793  o Made relevant methods virtual to verify performance impact.
794    If tests will behave reasonably, a further refinement in the
795    design of the class will be applied, in view of a more consistent
796    design review next year.
797
798Nov 3rd, 2003 - G.Cosmo  (geomnav-V05-02-03)
