10This file should be used by G4 developers and category coordinators
11to briefly summarize all major modifications introduced in the code
12and keep track of all category-tags.
13It DOES NOT substitute the CVS log-message one should put at every
14committal in the CVS repository !

[1315]20March 8th, 2010 - G.Cosmo (geomnav-V09-03-00)
21-------------------------
22- Avoid unnecessary creation of string for debug purposes in G4PropagatorInField.
23 Courtesy of P.Elmer (CMS).
24- Some printout formatting...
[1228]25
[1315]26December 11th, 2009 - J.Apostolakis (geomnav-V09-02-11)
27-----------------------------------
28- Implemented field by region in G4PropagatorInField, with extra checking of
29 logical volume.
[1228]30
[1315]31November 30th, 2009 - J.Apostolakis (geomnav-V09-02-10)
32-----------------------------------
33- Fixes in G4VIntersectionLocator:
34 * Fixed problem in ReEstimateEndPoint() behaviour for very small steps.
35 * Corrected constructor to ensure that it initialises all data members.
36 * Labelled the methods (in header) to make noticable those that must change
37 at every step (attributes: 'ChordFinder', 'EpsilonStep', 'Navigator').
38
[1228]39Nov 23rd, 2009 - J.Apostolakis
40------------------------------
[1315]41- Fixes in G4PropagatorInField.cc:
42 * Revised condition for flagging ZeroStep to avoid fake triggering. Small
43 proposed steps (from Physics) could trigger the previous simple condition
44 for Tiny/Zero Problem steps.
[1228]45
[1315]46November 12th, 2009 - J.Apostolakis (geomnav-V09-02-09)
47-----------------------------------
48- Cleanup of minor methods in G4PropagatorInField:
49 * Added new method RefreshIntersectionLocator() to update the state of locator.
50 It is used to synchronise with G4IntersectionLocator.
51 * Deleted long obsolete methods: SetAccuraciesWithDeltaOneStep(),
52 SetDeltaIntersection() and SetDeltaOneStep().
53 * Revised implementation to avoid using the older methods GetDeltaIntersection()
54 and GetDeltaOneStep().
[1228]55
[1315]56November 12th, 2009 - J.Apostolakis (geomnav-V09-02-08)
57-----------------------------------
[1228]58- Refined G4PropagatorInField.cc:
59 * Changed parameters for treating consecutive tiny/zero steps:
60 - the value of default decrease factor to 0.25 (from 0.1),
[1315]61 - the value is not used when the step size falls below a certain thresholds
62 This threshold is changed. It is expressed as a multiple of fZeroStepThreshold
63 instead of kCarTolerance. This, since the thresholds were meant to refer to
64 the ZeroStepThreshold (it was kCarTolerance), and the values were now much
65 larger than 'ZeroStepThreshold'.
66 - The value given to the decrease factor after the first such thresholds is
67 changed to 0.35 instead of 0.25, 0.5.
[1228]68 * Improved printing of Diagnostic message.
69
[1315]70November 3rd, 2009 - J.Apostolakis (geomnav-V09-02-07)
71----------------------------------
[1228]72- Refined G4PropagatorInField.cc:
[1315]73 * Added new member fZeroStepThreshold, to enable tuning of threshold for
74 Tiny/Zero steps.
[1228]75 * Changed default value from 0.5 * kCarTolerance
[1315]76 to max (100,000 * kCarTolerance, 0.1 * micron )
77 * This is first revision to address problem seen at boundary of volumes
78 (Reports of ATLAS).
[1228]79
80June 2nd, 2009 - J.Apostolakis (geomnav-V09-02-06)
81------------------------------
82- Fix in G4PropagatorInField::SetNavigator
83 * Forward new Navigator to IntersectionLocator.
84
[1058]85May 20th, 2009 - P.Arce (geomnav-V09-02-05)
86-----------------------
87- Added method BuildContainerSolid() taking a solid as argument to
88 G4PhantomParameterisation. Added protection to GetMaterialIndex()
89 for zero index.
90
91May 18th, 2009 - T.Nikitina (geomnav-V09-02-04)
92---------------------------
93- Enhanced algorithm for 'FB_intersects' in order to speedup BrentLocator.
94- Fix in the usage of the geometrical tolerance in G4VIntersectionLocator
95 in method AdjustementOfFoundIntersection().
96
97May 13th, 2009 - J.Apostolakis (geomnav-V09-02-03)
98------------------------------
99- Fix in G4PathFinder: A geometry is at a boundary if its step is within
100 tolerance of the minimum step for any geometry.
101
102May 5th, 2009 - T.Nikitina (geomnav-V09-02-02)
103--------------------------
104- Fix in G4Navigator::ComputeStep() for the computation of rotation of the
105 'LocalExitNormal' in cases when DistanceToOut() returns non-valid normal
106 for optical photons in rotated solids. Addresses problem report #1059.
107
108February 26th, 2009 - T.Nikitina (geomnav-V09-02-01)
109--------------------------------
110- Fixed problem in G4BrentLocator::EstimateIntersectionPoint() responsible
111 for rare cases of negative steps.
112
113January 27th, 2009 - G.Cosmo (geomnav-V09-02-00)
114----------------------------
115- Added G4RegularNavigationHelper class, used by G4RegularNavigation for
116 counting the number of step lengths in each voxel of the regular structure
117 (by P.Arce).
118- Some code cleanup...
119
120December 11th, 2008 - T.Nikitina (geomnav-V09-01-10)
121--------------------------------
122- Reinstated G4MultiLevelLocator as the default locator to allow for proper
123 tuning of parameters in propagation in field and avoid CPU penalty currently
124 induced by default parameters.
125- Corrected text in exceptions in locators classes.
126
[921]127November 14th, 2008 - T.Nikitina, J.Apostolakis (geomnav-V09-01-09)
128-----------------------------------------------
129- Introduced first implementation of new optional method in locator classes
130 AdjustementOfFoundIntersection() using surface-normal of the intersecting
131 solid to boost accuracy. Added the optional call to the new method in each
132 concrete locator.
133- Removed unnecessary accessors for Brent locator in G4PropagatorInField.
134- G4VoxelNavigation: implemented additional check when running in "check"
135 mode; if it is on the surface, ensure that it can move on next step;
136 either DistanceToIn(p,v) or DistanceToOut(p,v) should return a finite
137 value greater than the tolerance.
138
139November 10th, 2008 - G.Cosmo (geomnav-V09-01-08)
140-----------------------------

148- New classes: G4VIntersectionLocator, G4SimpleLocator, G4BrentLocator and
149 G4MultiLevelLocator.
150- Coworks with tag "field-V09-01-03".
151
152October 10th, 2008 - G.Cosmo (geomnav-V09-01-06)
153----------------------------
154- Introduced optional Boolean argument in G4Navigator::ComputeSafety() to
155 allow for computation of safety without modifying the state restoring of
156 the navigator.
157- Modified accordingly the following classes, for calls to ComputeSafety():
158 G4SafetyHelper, G4PathFinder (now calling ComputeSafety() with TRUE
159 argument to preserve navigator's state), G4MultiNavigator and
160 G4ErrorPropagationNavigator.
161
162May 5th, 2008 - T.Nikitina (geomnav-V09-01-05)
163--------------------------
164- Added Brent method for LocateIntersectionPoint() in G4PropagatorInField.
165 The Brent method is now used as default and can be switched off through
166 call to the proper accessor function SetBrentMethod().
167- Requires related update to G4ChordFinder in geometry/magneticfield module
168 included in tag "field-V09-01-02".
169
[831]170April 29th, 2008 - M.Asai (geomnav-V09-01-04)

183 ambiguous use of parentheses in condition statements.
184
185January 24th, 2008 - T.Nikitina (geomnav-V09-01-01)
186-------------------------------
187- G4PropagatorInField: changed condition for 'ReEstimationEndPoint'
188 in order to better handle very strict parameters of propagation.
189 Also added more verbosity in case of error for negative step.

279----------------------------------
280- G4PathFinder: added new methods GetNumberGeometriesLimitingStep()
281 and GetMinimumStep() needed by G4CoupledTransportation to see whether
282 to relocate.
283
284September 25th, 2007 - G.Cosmo (geomnav-V09-00-02)
285------------------------------
286- Some code cleanup in G4PathFinder. Switch off additional optimisation
287 for safety in method DoNextLinearStep().
288- Set 'fRecomputeFactor' in G4SafetyHelper to 0.0, to switch off internal

298-------------------------------
299- G4PathFinder:
300 o Include correction to signature of method PrepareNewTrack().
301 (This was done on a branch for this class in order to keep only
302 development of geomnav-V08-03-06)
303- G4PropagatorInField:
304 o Included revisions and fixes for G4PropagatorInField of June 8th.
305- This tag is based on "geomnav-V08-03-06" and does NOT include the

307
308July 5th, 2007 - G.Cosmo
309------------------------
310- G4PathFinder:
311 o Corrected signature to method PrepareNewTrack().
312 Resolves linking problems detected on SUN-CC platform.
313- Changes included in tag "geomnav-V08-03-02c", included in relase 9.0.p01.
314
315June 8th, 2007 - T.Nikitina

317- G4PropagatorInField:
318 o Put in the constructor creation of array of FieldTracks used in
319 LocateInterSectionPoint().
320 o Change in ReEstimateNewPoint() in order to handle cases with zero step
321 caused by diffCurve=0.

323 as per convention of geometry instead of 'DBL_MAX'.
324 (by J.Apostolakis, May 18th 2007)
325- Changes included in tag "geomnav-V08-03-02b", included in release 9.0.
326
327June 5th, 2007 - J.Apostolakis (geomnav-V08-03-07)
328------------------------------
329- G4PathFinder:
330 o New method to return the safety sphere last calculated for
331 a PreStep point (it could be a previous one - due to optimasation).
332 >> If last step(s) were smaller than safety, then for a linear
333 track (no field or no charge) Navigator's ComputeSafety is not
334 called. The older PreStep (previous step or some steps back
335 in case of many small steps) is stored for this - and provided.
336 o ComputeStep() still returns current PreStep point's safety (must).
337 o Revisions are to make this (used by CoupledTransportation) more
338 compatible with the old direct use of G4Navigator by G4Transportation.
339
340May 29th, 2007 - J.Apostolakis (geomnav-V08-03-06)
341------------------------------
342- G4Navigator
343 o Fixed **ComputeSafety**: wrong coordinates used (last tag only).
344 For certainty reinstated LocateGlobalPointWithinVolume (for now).
345 o Corrected calculation of fStepEndPoint (in ComputeStep)
346 for case of step not limited by geometry
347- G4PathFinder
348 o PrepareNewTrack: calls to re-initialise SafetyHelper (reset safety)
349 o ReLocate: Corrected check of move (avoid one side effect on stored safety)
350 --> ComputeSafety still results individual navigators' values.
351
352May 24th, 2007 - J.Apostolakis (geomnav-V08-03-05)
353------------------------------
354- G4PathFinder: 1 correction and 2 optimisations:
355 o PrepareNewTrack() clear safety - to avoid potential problems in overlaps.
356 o DoNextLinearStep() only calls ComputeStep() for a navigator whose safety
357 greater than the step.
358 o DoNextCurvedStep(), if there's one geometry, no longer calls
359 ComputeSafety() at start.
360- G4Navigator ComputeSafety:
361 o Corrected it to address use at non-endpoint
362 o Replaced call to LocateGlobalPointWithinVolume() with calls to
363 sub-navigators.
364
365May 21st, 2007 - G.Cosmo
366------------------------
367- Made 'fVerbose' protected in G4Navigator, reused in G4MultipleNavigator.
368- Some cleanup in G4MultipleNavigator implementation.
369- Make G4PathFinder singleton definition canonical.
370- Added method CheckPointExiting() in G4AuxiliaryNavServices utility
371 class (by P.Arce).
372
373May 19th, 2007 - J.Apostolakis (geomnav-V08-03-04)
374------------------------------
375- Corrections and additions in G4PathFinder:
376 1) Added calculation of start-point safety in DoNextCurvedStep
377 2) Corrected GetCurrentSafety() - uses mininum of 1)
378 3) Added method to obtain safety of one navigator (after call to all).
379 4) Deleted obsolete data member 'fMinSafety'.
380 5) If only one geometry, do not call WhichLimited in DoNextLinearStep (optimisation)
381 6) ComputeSafety: save the values of isotropic safety for each navigator
382
383May 18th, 2007 - A.Howard (geomnav-V08-03-03)
384------------------------
385- Fixed return value for G4PathFinder::ComputeStep in case of
386 step smaller than tolerance (now kInfinity): fixes one PathFinder issue (JA).
387- Added compiler flags for verbosity in G4PathFinder.cc
388- Added compiler flags for verbosity in G4MultiNavigator.cc
389
390May 18th, 2007 - G.Cosmo (geomnav-V08-03-02)
391------------------------
392- Use kAngTolerance and kRadTolerance from G4GeometryTolerance class.

397- Introduced new class G4ErrorPropagationNavigator, a specialised navigator
398 for performing double navigation in the detector geometry and on the
399 target surface for error propagation (by P.Arce).
400- Fixed bug in G4GeomTestSegment in case of TestPoint on the surface,
401 reducing cases of reported spurious overlaps.
402- Coworks with tag "global-V08-03-02".
403
404May 16th, 2007 - J.Apostolakis (geomnav-V08-03-00a)
405------------------------------
406- Moved to G4PathFinder version without extra prints
407
408April 26th, 2007 - G.Cosmo (geomnav-V08-03-00)
409--------------------------
410- Use call to G4GeometryTolerance instead of kCarTolerance where needed.
411- Revised data members in G4SafetyHelper to conform to convention.
412- Requires tag "global-V08-03-00" and related tag set.
413
414April 26th, 2007 - T.Nikitina (geomnav-V08-02-03)
415-----------------------------
416- Fixed case of out of range access in G4GeomTestSegment responsible for
417 crashes observed when recursive-grid test for overlaps was run.
418 Addressing problem report #784.
419
420April 20th, 2007 - G.Cosmo (geomnav-V08-02-02)
421--------------------------
422- Some cleanup and minor cosmetics ...
423
424April 12st, 2007 - V.Ivanchenko
425-------------------------------
426- G4SafetyHelper become a unique class, which can be accessed via
427 G4TransporationManager. Depending on type of navigation (single
428 world or multiple navigation) it uses mass navigator or G4PathFinder.
429 All calls from EM processes to geometry are provided by G4SafetyHelper.
430- G4TransportationManager: added G4SafetyHelper.
431- G4PathFinder: initialisation of G4SafetyHelper.
432- Tagged "geomnav-V08-02-02-beta2".
433
434March 31st, 2007 - J. Apostolakis
435---------------------------------
436- G4Navigator:
437 o New method CheckNextStep() makes a trial step, without
438 changing the state of the Navigator (to be verified).
439 It is a variant of ComputeStep, whose signature it shares.
440- Tagged "geomnav-V08-02-02-beta1".
441
442February 13th, 2007 - J.Apostolakis
443-----------------------------------
444- G4Navigator:
445 o Improvement for creating touchable history when located outside world.
446 Retain whether last point was located outside, and if so call default
447 TouchableHistory constructor (that initialised world to null).
448 NOTE: testing found problems with SteppingManager::SetInitialStep()
449 as the Vertex physical volume was not set. Protection is potentially
450 required, or bigger issue to be resolved.
451 Currently, changes in G4Navigator.hh,cc are safe, but the fix in .icc is
452 temporarly suspended and NOT included.
453- Attempted fix created Dec 7th, 2006
454
455February 13th, 2007 - J.Apostolakis (geomnav-V08-02-01)
456-----------------------------------
457- G4PropagatorInField:
458 o Implemented ClearPropagatorState() to clear all the track-dependent
459 state (incl. safety, zero-steps, loop flag ...).
460 ** Calling this is mandatory for each new track because in the case of
461 geometry overlaps, the safety can be easily inconsistent (and/or
462 incorrect) otherwise
463 ** Must be called from G4Transportation (or alternatives) !!
464- Fix created Jan 25th, 2007
465
466January 31st, 2007 - G.Cosmo (geomnav-V08-02-00)
467----------------------------
468- G4Navigator: forcing call to CheckOverlaps() on the current volume
469 before event abortion for cases of stuck tracks.
470- Requires tag "geommng-V08-02-00".

478
479November 18th, 2006 - J.Apostolakis (geomnav-V08-01-07)
480-----------------------------------
481- G4PathFinder:
482 o Fix for problem when step is fully taken.
483 Note: this occurs due to optimisation in PiF that avoids calling
484 G4(Multi)Navigator!!
485 o Function LimitedString( ELimited lim ) enables printing this enum
486 o Improved printing in IntersectChord. Deleted/simplified few prints in
487 ComputeStep().
488- G4MultiNavigator: cleanup, cosmetics
489
490November 13th, 2006 - G.Cosmo (geomnav-V08-01-06)

509 o NOTE: Special tags made (later) not including the Developments in
510 G4TransportationManager, G4PathFinder, G4SafetyHelper for parallel
511 navigation. i.e. - based on tag "geomnav-V08-01-03".
512
513November 11th, 2006 - J.Apostolakis
514-----------------------------------
515- Created G4MultiNavigator class and utilised it from G4PathFinder
516 to implement curved trajectory parallel navigation.
517
518November 10th, 2006 - J.Apostolakis (geomnav-V08-01-03)
519-----------------------------------
520- G4PropagatorInField:
521 o Fix in LocateIntersectionPoint(), to subdivide in case it cannot find
522 intersection point quickly (T.Nikitina).
523 First version, only one level of cutting

534
535November 4th, 2006 - M.Asai
536---------------------------
537- G4TransportationManager:
538 o added new method SetWorldForTracking() to enable change of world from
539 the RunManager.
540
541October 31st, 2006 - J.Apostolakis
542----------------------------------
543- G4SafetyHelper
544 o Added new class variable 'fUseParallelGeometries', to enable
545 it to work call G4Navigator of Mass geometry directly, in
546 the case of single geometry (when G4PathFinder is disabled).
547 o Default value is currently 'true' --> for parallel navigation development.
548- G4PathFinder
549 o Improved the code that checks within relocation whether position
550 is proposed to be moved outside safety sphere from endpoint.
551
552October 26th, 2006 - G.Cosmo (geomnav-V08-01-02)
553----------------------------

555 o Added inline methods EnteredDaughterVolume() and ExitedMotherVolume() to
556 allow for verification of a point entering a daughter volume or exiting
557 the mother volume.
558 o Made LocateGlobalPointAndSetup() method virtual. Moved to non virtual
559 and inline LocateGlobalPointAndUpdateTouchableHandle() method.
560 o Moved 'fHistory' data member to protected to aloow for more complete
561 subclassing.
562 o Minor cosmetics to recently introduced printout diagnostics in
563 ComputeSafety() method.
564- G4TransportationManager:
565 o Added methods to access the list of the registered worlds.

567 G4PathFinder. It resumes from tag "geomnav-V08-00-01"; anything else
568 introduced after it, except for changes in G4Navigator, is NOT included !
569
570October 25th, 2006 - J.Apostolakis
571----------------------------------
572- G4PathFinder: fixed initialisation of cached value for the
573 G4TransportationManager to cope with singletons.
574
575October 16th, 2006 - J.Apostolakis (geomnav-V08-01-01)
576----------------------------------
577- G4Navigator: moved debug printing behind fVerbose conditions
578
579October 12th, 2006 - J.Apostolakis (geomnav-V08-01-00)
580----------------------------------
581- New class G4SafetyHelper to aid multiple scattering inn
582 determining the correct Mass geometry step (via PathFinder)
583 and all-geometry safety.
584- Several revisions, fixes to G4PathFinder.
585
586June 8th, 2006 - J.Apostolakis (geomnav-V08-00-06)
587------------------------------
588- G4PathFinder:
589 o New method 'ComputeSafety' to compute safety at endpoint of last step.
590
591June 2nd, 2006 - J.Apostolakis (geomnav-V08-00-05)
592------------------------------
593- G4PathFinder:
594 o New method ReLocate() for non-Transportation classes to call when moving
595 the endpoint of a particle. Uses LocateGlobalPointWithinVolume() method
596 of the navigators.
597 o Small fixes and protection of debug printing with Verbose flag.
598 o Default verbose level is now 0.
599
600May 28th, 2006 - J.Apostolakis (geomnav-V08-00-04)
601------------------------------
602- G4PathFinder:
603 o Check whether a process shifted the position since the last step.
604 o Corrected checking for 'Unique', i.e. one process limiting step.
605 o Revised printing (more information, some protected by verbose flag).
606
607May 27th, 2006 - J.Apostolakis (geomnav-V08-00-03)
608------------------------------
609- G4PathFinder revised significantly:
610 o Workaround for problem of CreateHistory() when outside world.
611 o Revised for new counting of Navigator IDs (M.Asai).
612 o Added MovePoint() method that signals if it moved.
613 o Added state to cope with cases where a full step is taken,
614 i.e. to cope with steps that return kInfinity:
615 New state:
616 RelocatedPoint - to show if it is moved;
617 TrueMinStep - finite whereas reported can be kInfinity.
618 and to aid in clarifying the state of the (singleton) object:
619 LastStepNo - already kept in one method (static), now exposed;
620 CurrentStepNo - mostly for debugging and printing out.
621 o Small improvements in tests.
622
623May 23rd, 2006 - J.Apostolakis (geomnav-V08-00-02)
624------------------------------
625- Added new prototype class G4PathFinder to coupled navigation
626 in parallel geometries.
627
628May 22nd, 2006 - G.Cosmo (geomnav-V08-00-01)
629------------------------
630- Extended G4TransportationManager to handle multiple navigators.
631 Preserved interface for navigation in mass/tracking geometry.
632- Added activation flag to G4Navigator and related accessor methods.
633
634Feb 8th, 2006 - J.Apostolakis (geomnav-V08-00-00)
635-----------------------------
636- Addressing problem with convergence in LocateIntersectionPoint()
637 of G4PropagatorInField (problem identified by Atlas, observed when
638 requesting high precision, i.e. small values of eps_min/max, delta_one_step,
639 due e.g. to need for small delta_intersection):
640 o First solution by increasing maximum iterations (from 100 to 10,000).
641 o Until correct information can be returned, an Exception is thrown
642 in case of too many iterations.
643 o Warn in case over 1000 iterations, to let user see difficulty.
644- This fix is an interim solution, in lieu of improving the algorithm
645 for location (or returning correct incomplete progress).
646
647Nov 24th, 2005 - J.Apostolakis (geomnav-V07-01-02)
648------------------------------
649- Revised G4ParameterisedNavigation, to use new interface for
650 ComputeMaterial(). Now no longer needing 'Physical Touchable'.
651
652Sep 19th, 2005 - G.Cosmo (geomnav-V07-01-01)
653------------------------
654- G4DrawVoxels: removed unnecessary 'panic' message in ComputeVoxelPolyhedra()

692------------------------
693- G4Navigator: corrected computation of fGrandMotherExitNormal in ComputeStep()
694 in the case where a not valid exit-normal exists.
695
696Sep 11th, 2004 - G.Cosmo (geomnav-V06-02-02)
697------------------------
698- Dump out contents from the solid when a fatal G4Exception is thrown from
699 the navigators in ComputeStep().
700 Modified files G4NormalNavigation.cc, G4ParameterisedNavigation.cc,
701 G4ReplicaNavigation.cc, G4VoxelNavigation.cc.
702
703Aug 31st, 2004 - D.C.Williams (geomnav-V06-02-01)
704-----------------------------
705- G4GeomTestSegment: fix to correctly determine whether starting trajectory
706 is entering or exiting the solid when the starting point is on a surface.
707 Added additional tests on solid consistencies (from roundoff sometimes) to
708 avoid incorrect overlap warnings. Addresses problem reports #610 and #652.
709
710Jun 29th, 2004 - G.Cosmo (geomnav-V06-02-00)
711------------------------
712- Fixed zero step-length problem in G4ReplicaNavigation::ComputeStep()
713 for cases where different replica types are coincident. Resolves
714 problem report #633.
715- G4NormalNavigation: added extra verbosity to print out information
716 for each solid which returns a 'lowest-yet' step, including the
717 mother volume. It is activated by setting verbose level to 2 or
718 more (J.Apostolakis).
719
720Jun 18th, 2004 - G.Cosmo (geomnav-V06-01-03)
721------------------------
722- Enhanced check for null step in G4Navigator::ComputeStep().
723 Now attempting a corrective action after 10 consecutive zero steps.
724 Event gets aborted after 25 zero steps.
725
726Jun 15th, 2004 - G.Cosmo (geomnav-V06-01-02)
727------------------------
728- Relax exception in G4Navigator::ComputeStep() for stuck tracks.

732------------------------
733- Added check to G4Navigator to count the number of steps with zero length
734 and issue an exception for tracks that get stuck in a loop (J.Apostolakis).
735- Modified GNUmakefile to define G4GEOMETRY_ALLOC_EXPORT flag for DLLs
736 build on Windows.
737
738May 17th, 2004 - G.Cosmo (geomnav-V06-01-00)
739------------------------
740- Added more verbosity on solids response for navigators (optimised/not
741 optimised) if "check_mode" state is combined with verbose level-1.
742
743Mar 11th, 2004 - G.Cosmo (geomnav-V06-00-02)
744------------------------
745- Added "check_mode" state for navigators. The state can be activated by
746 a new UI command (geometry/navigator/check_mode [true/false]) and will
747 force more strict and less tolerant checks in step/safety computation to
748 verify the correctness of solids' response in the geometry.
749- Reorganised verbosity levels. Added more useful information activated
750 when in G4VERBOSE mode and verbosity level selected.
751 Fixed output formatting when entering/exiting verbose blocks.
752
753Feb 27th, 2004 - G.Cosmo (geomnav-V06-00-01)
754------------------------

758
759Feb 9th, 2004 - J.Apostolakis (geomnav-V06-00-00)
760------------------------------
761- G4PropagatorInField.cc:
762 o ReEstimateEndpoint: Changed to cope with a failure of AccurateAdvance,
763 by calling it iteratively up maximum 20 times.
764 o SetVerboseLevel, now forwards the verbosity (minus 3) to integration driver
765
766Dec 11th, 2003 - J.Apostolakis (geomnav-V05-02-15)
767------------------------------
768- G4PropagatorInField.cc:
769 o LocateIntersectionPoint: Refined re-setting of finalSection.
770 --> Endpoint recalculation is returned only for final section.
771 (trial fix in -14 is replaced by above code)
772 o Fixed ReEstimateEndPoint which ignored return code of AccurateAdvance
773 and moved to short end-point for long requests
774 It now leaves the endpoint unchanged, when it cannot improve it.
775 o Few format changes for PrintStatus
776
777Dec 10th, 2003 - J.Apostolakis (geomnav-V05-02-14)
778------------------------------
779- G4PropagatorInField.cc on top of latest (not 1.7):
780 o Fix for the case where two previous corrections are 'operational'
781 Problem if the current endpoint is not the final one, and it has been
782 recalculated, and we need to go beyond the current section to the
783 final one -- the recalcuted endpoint no longer valid!
784
785Dec 10th, 2003 - J.Apostolakis (geomnav-V05-02-13)
786------------------------------
787- G4PropagatorInField.cc:
788 o Gone back to version 1.7, without the fix in LocateIntersectionPoint
789 for the "long-standing error".
790
791Dec 5th, 2003 - G.Cosmo - (geomnav-V05-02-12)
792------------------------
793- G4TransportationManager.cc:
794 o removed initialisation of allocators for navigation levels, where they
795 were introduced as workaround for solving static initialisation a long
796 time ago. Now moved to "volumes" module, where they should belong, in
797 G4TouchableHistory.cc.
798- Restored original unit-tests, using inherited navigator.
799 --> Requires geomvol-V05-02-08
800
801Dec 4th, 2003 - J.Apostolakis (geomnav-V05-02-11)
802------------------------------
803- G4PropagatorInField.cc
804 o Corrected placement of #endif for two #ifdef VERBOSE
805
806Dec 2nd, 2003 - J.Apostolakis (geomnav-V05-02-10)
807------------------------------
808- G4PropagatorInField[.hh.cc]:
809 o Fixed LocateIntersectionPoint for long-standing error.
810 A section of the chord was not considered in use case where
811 a previous chord at first appeared to have an intersection, but did not.
812
813Nov 26th, 2003 - J.Apostolakis (geomnav-V05-02-09)
814------------------------------
815- G4PropagatorInField[.hh.cc]:
816 o Added argument Method LocateIntersectionPoint G4bool& recalculatedEndPt
817 to return 'true' if the endpoint has been recalculated.
818 This fixes a problem that can occasionally cause the skipping of a volume
819 boundary - in the case when a re-integration was done near a boundary,
820 because the new endpoint was previously not passed back.
821 o ComputeStep also changed to accept above recalculation.
822 o New method GetVerboseLevel(), closer to std naming than Verbose()
823
824Nov 14th, 2003 - J.Apostolakis (geomnav-V05-02-08)
825------------------------------
826- Retagged the files of tag "geomnav-V05-02-07", due to tagging with same
827 name incorrectly files in another directory and, as such confusing Bonsai.
828
829Nov 13th, 2003 - J.Apostolakis (geomnav-V05-02-07)

841 o Renamed method LocateGlobalPointAndSetup(p,v,history) to
842 ResetHistoryAndLocate(p,v,history).
843 o Moved to protected the following methods: GetCurrentLocalCoordinate(),
844 ComputeLocalPoint(), ComputeLocalAxis(), NetTranslation(),
845 NetRotation(), EnteredDaughterVolume().
846 o Fixed consistency of inline/not-inline implementations of methods.
847- Coworks with tag "tracking-V05-02-03".
848
849Nov 6th, 2003 - J.Apostolakis (geomnav-V05-02-05)
850-----------------------------
851- G4PropagatorInField[.hh.icc.cc]:
852 o Implements move of EpsilonMin / Max to G4FieldManager.
853- Requires and coworks with "field-V05-02-04" or later tag.
854
855Nov 6th, 2003 - G.Cosmo (geomnav-V05-02-04)
856-----------------------
857- G4Navigator[.hh.icc.cc]:
858 o Made relevant methods virtual to verify performance impact.
859 If tests will behave reasonably, a further refinement in the
860 design of the class will be applied, in view of a more consistent
861 design review next year.
862
863Nov 3rd, 2003 - G.Cosmo (geomnav-V05-02-03)
864-----------------------
