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

----------------------------------------------------------
Nov 29th, 2002 J. Apostolakis - geomvol-V04-01-08
- G4PropagatorInField: Use safety in G4PropagatorInField.
(Adds to the state of this class).
Nov 29th, 2002 S. Sadilov - geomvol-V04-01-07a
- Minor corrections (cout/G4cout, endl/G4endl) to files
G4IdentityTrajectoryFilter.cc G4VCurvedTrajectoryFilter.cc
Nov 27th, 2002 G. Cosmo - geomvol-V04-01-07
- G4BlockingList.cc: fixed initialisation of fBlockTagNo to 1.
Fixes warnings reported by Valgrind to G4BlockingList, G4VoxelNavigation
and G4ParameterisedNavigation.
Nov 19th, 2002 J. Generowicz - geomvol-V04-01-06
- Created G4IdentityTrajectoryFilter, making G4VCurvedTrajectoryFliter
truly abstract.
Nov 8th, 2002 J. Generowicz
- Introduced G4VCurvedTrajectoryFilter, and gave PIF means of
manipulating and communicating with it.
Oct 29th, 2002 J. Apostolakis - geomvol-V04-01-05
- G4PropagatorInField
Re-introduced memory of Charge Mass and Momentum into PropagatorInField,
in order for it to message the correct ChordFinder at each step with this
information. It now does this task.
Aug 6th, 2002 G. Cosmo - geomvol-V04-01-04
- Formatting cleanup in source implementation files.
Jul 29th, 2002 G. Cosmo - geomvol-V04-01-03
- G4PropagatorInField[.hh.icc.cc]:
Restored call to GetChordFinder()->SetChargeMomentumMass() in method
SetChargeMomentumMass(), as was originally in release 4.1.
All modifications introduced in tag "geomvol-V04-00-11" have now been removed.
Jul 29th, 2002 G. Cosmo - geomvol-V04-01-02
- G4PropagatorInField.cc: (J.Apostolakis)
o Restored ComputeStep() as it was before tag "geomvol-V04-00-11", by
removing call to GetChordFinder()->SetChargeMomentumMass().
This call was responsible for failure of unit tests, where no field strength
was observed in some cases.
o Set 'fNoZeroStep' to zero if (fNoZeroStep > fAbandonThreshold_NoZeroSteps)
at the end of ComputeStep(). Fixes problem report from P.M.DeFreitas
occurring in Mokka (Tesla), when reading primaries from their Pythia files.
- G4PropagatorInField[.hh.cc]:
o Removed not-implemented constructor taking G4Navigator* as argument.
o Get rid of static const data for default epsilonStep size.
o Initialise all data members in constructor !
o Code cleanup.
Jul 24th, 2002 G. Cosmo - geomvol-V04-01-01
- Removed static initialisations of data of G4FieldManager.
Coworks with tag "field-V04-01-01".
Jul 23rd, 2002 G. Cosmo - geomvol-V04-01-00
- Some code cleanup and cosmetics...
Jun 18th, 2002 J. Apostolakis - geomvol-V04-00-11
- G4PropagatorInField.cc
o Fix for messaging incorrect ChordFinder with Mass, Charge, Momentum.
( Problem seen for multiple FieldManagers - reported by Grahame Blair )
Jun 13th, 2002 J. Apostolakis - geomvol-V04-00-10
- G4Navigator.cc
o Fix for navigation problem (dereference null volume pointer) in exampleN05
caused by ExitNormal fix.
Jun 3rd, 2002 G. Cosmo - geomvol-V04-00-09
- G4Navigator[.hh.icc.cc]:
o Cosmetics for Software Reference Manual and formatting.
o Fixed few cases of endl/G4endl mystypes...
May 31st, 2002 J. Apostolakis - geomvol-V04-00-08
- G4Navigator.cc:
o Corrections for problem report #351, #284 concerning ExitNormal:
- using Daugther's solid preferentially (if applicable)
- adjusting fEntering/fEnteredDaugther in LocateGlobalPointAndSetup
to enable this
- correcting location of point for which exit normal is requested
for 'non-convex point' on solid boundary
Thanks to Bryan Tipton (tipton@krl.caltech.edu),
Antonis Papanestis (antonis.papanestis@cern.ch)
and Peter Gumplinger for their demonstrations of the delicate problem.
May 15th, 2002 G. Cosmo - geomvol-V04-00-07
- G4ParameterisedNavigation:
o Introduced 3D voxelisation technique for parameterised volumes with
unspecified axis. Changed to become subclass of G4VoxelNavigation and
adopt the same voxel location algorithms for optimised navigation.
- G4VoxelNavigation:
o Changed to become base class for optimised navigation.
o Cosmetics and reformatting.
- G4NormalNavigation.icc, G4ReplicaNavigation.icc, G4VoxelNavigation.icc:
o Minor optimisations.
o Cosmetics and reformatting.
- G4Navigator.cc:
o Invoke specific VoxelLocate call for parameterised navigation.
- Co-works with "global-V04-00-06" and "geommng-V04-00-05".
Apr 19th, 2002 G. Cosmo - geomvol-V04-00-06
- Moved inline constructors and destructors to no inline.
Affected files: G4BlockingList[.icc,cc], G4NavigationHistory[.icc,.cc],
G4PropagatorInField[.hh.icc.cc].
Apr 3rd, 2002 G. Cosmo - geomvol-V04-00-05
- G4GeometryMessenger[.hh.cc]: added new commands to exploit more features of the
G4GeomTestVolume class for detecting geometry overlaps:
o /geometry/test/grid_test - runs the default grid test, same as "run".
o /geometry/test/recursive_test - runs the grid test in recursive mode.
o /geometry/test/cylinder_test - to shoot lines in a cylindrical pattern.
o /geometry/test/line_test - to shoot a line according to position and direction.
Mar 22nd, 2002 J. Apostolakis - geomvol-V04-00-04
- G4PropagatorInField: added Set/Get methods for MaximumEpsilonStep
Feb 20th, 2002 G. Cosmo - geomvol-V04-00-03
- G4GeometryMessenger.cc: fixed local variable name not to clash with
class data member.
Jan 21st, 2002 J. Apostolakis - geomvol-V04-00-02
- G4Navigator: reset blocked volume when locating 'within volume',
after ensuring that it does not get called when
ComputeSafety() is at a boundary.
--> Fix for cases of longstanding 'Point P is Inside' errors.
Jan 10th, 2002 G. Cosmo - geomvol-V04-00-01
- Activated mechanism in GNUmakefile for allowing compilation with
G4DEBUG_FIELD or G4DEBUG_NAVIGATION flags. Replaced DEBUG with
G4DEBUG_NAVIGATION in G4Navigator.cc.
Jan 8th, 2002 J. Apostolakis - geomvol-V04-00-00
- G4AuxiliaryNavServices
o Fixed it so that it only considers whether a (Point,Direction) 'ray' if
it is on the surface (it was mistakenly also checking those inside, and
rejecting them.)
[ This erroneous condition occurred frequently in the new usage of Locate
with Direction to initialise a step.
It's unclear if it occurred also at other times.]
Jan 8th, 2002 G. Cosmo
- Fixed compilation problems and warnings on unit tests.
(G.Cosmo, R.Chytracek)
Dec 11th, 2001 G. Cosmo - geomvol-V03-02-08
- G4Navigator:
o Added kNormal and Copy Number to NewLevel (Navigation Level) for
Normal Navigation
Now all TouchableHistory objects should have a valid entry in ReplicaNumber:
- in the case of a placement volume it will be the copy number
- in replicated volumes it will be the replica number
o Commented out fix introduced in geomvol-V03-02-05.
Dec 11th, 2001 J. Apostolakis - geomvol-V03-02-07
- G4Navigator:
o Undoing the fix in geomvol-V03-02-05 -- because of problems in
several tests (mostly large N tests).
----> Must resolve these !! <----
Dec 8th, 2001 J. Apostolakis - geomvol-V03-02-06
- G4PropagatorInField:
o additional thresholds for No of steps, + get/Set methods
o Modified choice of subsequent step size in case of Zero step
- decrease quickly at first to try to ensure that the first/second
"re-steps" are enough in most cases.
- utilise addition threshold parameters (for # of steps)
to slow down the rate of decrease of the step size
for the 'difficult' cases which do not converse after
a few steps.
Dec 6th, 2001 J. Apostolakis - geomvol-V03-02-05
- G4Navigator:
Fix for Locate Global Point Within Volume: clear state
variables (that had erroneously been forgotten).
Dec 6th, 2001 R. Chytracek - geomvol-V03-02-04
- G4Navigator:
o Fixed mirroring of the input argument for global direction into
local variable in LocateGlobalPointAndSetup().
o Cosmetics for the Software Reference Manual in .hh file.
Dec 4th, 2001 J. Apostolakis - geomvol-V03-02-03
- G4Navigator:
o Modified the interface
- creating a new ResetState method (that only reset state - not stack)
- adding a new optional argument to LocateGlobalPointAndSetup method
- adding direction argument to LGPAS w/ touchable history
o Modified the implementation
- to reset its state when touchable history is used to re-initialise it
- to use the direction in LocateGlobalPointAndSetup methods!
- G4PropagatorInField:
o Added use of new Largest Acceptable Step data member.
o Protected, in reseting of Proposed Step length, against
making it bigger in cases where several zero steps seen.
o Several debugging prints added. (only in G4Verbose, ...)
Nov 28th, 2001 J. Apostolakis - geomvol-V03-02-02
- Added GetCurrentFieldManager method to PropagatorInField
- Incorporates additions seen in "geomvol-V03-02-00a/b/c"
and in "geomvol-V03-02-01".
- This tag is required by the new tag "transport-V03-02-06" in Transportation.
Oct 18th, 2001 J. Apostolakis - geomvol-V03-02-01
- Added a new 'maximum' epsilon value in G4PropagatorInField,
as some ill-conditions appear to be due to large proposed relative errors.
NOTE: does NOT include changes in "geomvol-V03-02-00a/b/c".
Nov 8th, 2001 G. Cosmo - geomvol-V03-02-00c
- Added handles for reference counting: G4GRSSolidHandle, G4GRSVolumeHandle,
G4TouchableHistoryHandle.
- Modified G4Navigator for reference counted touchables. Introduced new methods
CreateTouchableHistoryHandle() and LocateGlobalPointAndUpdateTouchableHandle(...).
- New unit tests testG4ParameterisedMaterial.cc and testG4TouchableHandle.cc.
Nov 1st, 2001 G. Cosmo - geomvol-V03-02-00b
- G4GeometryMessenger.cc: fixed definition of unit category for tolerance.
Oct 24th, 2001 G. Cosmo - geomvol-V03-02-00a
- Moved G4GeomTestMessenger from geometry/verification to geometry/volumes.
Renamed to G4GeometryMessenger.
- GeometryMessenger: renamed directory to geometry/test. Added directory
geometry/navigator. Added geometry/navigator/reset command
for resetting navigation history and position.
- G4PropagatorInField.icc: fixed warning on Linux-g++....
Oct 18th, 2001 J. Apostolakis - geomvol-V03-02-00
- Corrected the initialisation of fEpsilonMin in G4PropagatorInField
constructor, which was forgotten.
May 31st, 2001 G. Cosmo - geomvol-V03-01-08
- Fixed usage of 'fabs', which belongs to global scope, NOT in std
namespace. Detected by compilation error on DEC ISO/ANSI setup.
- G4VoxelNavigation.icc: initialised data-member in initialiser list of
constructor with explicit initialisation to dummy values to allow porting
on ObjecSpace STL.
May 23rd, 2001 J. Apostolakis - geomvol-V03-01-07
- Added methods to Set the minimum epsilon (relative accuracy) to
Propagator In Field.
May 23rd, 2001 J. Apostolakis - geomvol-V03-01-06
- Added new parameter to Propagator In Field,
fEpsilonMin which is the minimal relative accuracy for MF driving.
May 23rd, 2001 J. Apostolakis - geomvol-V03-01-05
- Moved Delta Intersection and One Step from PropagatorInField to Field Manager.
- Modified G4TransportationManager.cc to initialise default values accordingly.
(Incorporating changes into a tag, finally, after fix to G4FieldManager
constructors. )
o This tag requires and co-works with field-V03-01-01.
This now ENABLES the use of different Field Managers for different parts of
the detector. First implementation allows a volume that has a field
manager to override the global one.
Note: All field managers currently must refer to fields in global coordinates
o New ability: to set the delta accuracy parameters differently in different
volumes (even while maintaining the same field as the global one!).
May 23rd, 2001 G. Cosmo - geomvol-V03-01-04
- Fixes in G4ReplicaNavigation for bug reports #253 and #254:
o in VoxelLocate(...), treated particular case of rotational symmetry
with extent over 360 degrees (courtesy of H.Boie).
o in DistanceToOutPhi(...), fix to correctly handle cases where the
starting point is on boundary of replicas and direction is along boundary.
May 15th, 2001 G. Cosmo - geomvol-V03-01-03
- G4AuxiliaryNavServices::CheckPointOnSurface(): added additional check to resolve
endless looping of G4Navigator in case the track is passing through a point, edge
or surface shared by two solids.
This problem occured when G4Navigator was trying to transport a particle when
exiting a solid. Transportation will now perform a few zero steps and continues
stepping instead of looping around the same point. Fixes problem report #185.
April 27th, 2001 G. Cosmo - geomvol-V03-01-02
- G4VoxelNavigation.icc: fixed compilation warnings on HP-UX, concerning
potential uninitialised vector elements.
April 20th, 2001 G. Cosmo - geomvol-V03-01-01
- Updated unit tests to conform to recent STL vector migration.
April 17th, 2001 G. Cosmo - geomvol-V03-01-00
- Migration to STL vector:
o Modified classes:
G4VoxelNavigation, G4NavigationHistory, G4BlockingList,
G4LogicalSkinSurface, G4LogicalBorderSurface.
o Removed GetIndex() and table-index data from G4LogicalSkinSurface
and G4LogicalBorderSurface.
March 19th, 2001 J. Apostolakis - geomvol-V03-00-03
- G4PropagatorInField:
Modified to use new (not obsolete) methods of G4FieldTrack.
Deleted old/obsolete ComputeStep method
(that was being used only for testing purposes, but
could not be used anymore after change to Momentum Integration.)
March 12th, 2001 G. Cosmo - geomvol-V03-00-02
- G4ReplicaNavigation::ComputeStep(): apply push of kCarTolerance to ourStep
in case the proposed step is zero.
February 23rd, 2001 G. Cosmo - geomvol-V03-00-01
- Restored original 0.5 shift for kPhi transformation in ComputeTransformation()
methods, as original specifications from P.Kent impose.
- Fixed bug in ComputeTransformation(const G4int rNo, G4VPhysicalVolume* pVol)
where 'pVol' was NOT passed to SetPhiTransformation() in the kPhi case (!).
February 15th, 2001 G. Cosmo - geomvol-V03-00-00
- Fix in G4ReplicaNavigation::ComputeTransformation(...) for kPhi case.
Removed shift of 0.5 to center of replica volume to conform with original
specifications for replica transformations in Phi.
- Cosmetics in G4ReplicaNavigation.cc.
November 20th, 2000 G. Cosmo - geomvol-V02-00-01
- Fixes to remove warnings from "-Wall -ansi -pedantic" g++ compiler options:
o commented out variables declared and not used.
o fixed declaration of variables used before being initialised.
o fixed order of initialisation of member data in constructors.
o fixed usage of unsigned-int (size_t) for array indeces.
November 1st, 2000 G. Cosmo - geomvol-V02-00-00
- QA code revision and cleanup (+fixes from CodeWizard filtering):
o Added (private) copy constructor and assignment operator where needed.
o Added "const" qualifier to accessor methods, wherever needed.
o Added equality check on operator= where needed.
o Made destructor "virtual" for classes having virtual methods,
wherever missing.
o Changed virtual functions to non-inline wherever's the case.
o Changed return value to be "const" pointer to functions:
- G4LogicalBorderSurface::GetVolume1()
- G4LogicalBorderSurface::GetVolume2()
- G4LogicalSkinSurface::GetLogicalVolume()
o G4NavigationHistory: moved kHistoryMax and kHistoryStride to
geomdefs.hh and made static constants. Reorganised comments.
o G4VoxelNavigation: moved kNavigatorVoxelStackMax in geomdefs.hh.
Changed "do-loops" with "while-loops" where convenient.
o Added "inline" qualifier to methods' declarations.
o General cosmetics
June 2nd, 2000 J. Apostolakis - geomvol-V01-01-02
include/G4PropagatorInField.hh,icc
o Moved Delta Intersection and Delta One Step to FieldManager
(from Propagator in Field), to allow them to differ over the detector.
G4TransportationManager.cc
o Changed static variable for above (default values).
May 17th, 2000 G. Cosmo - geomvol-V01-01-01
G4ReplicaNavigation.cc:
- Added check to returned safety value in DistanceToOut(). Zero is
returned if the computed velue is less than kCarTolerance.
- Introduced temporary fix to ComputeStep() in the first step computation
for replica boundaries. 'ourStep' is not set to the computed 'sampleStep'
if 'sampleStep' happens to be zero.
This fix helps to get rid of infinite loops when a point is on a
shared surface of a replica or on a shared vertex; a more definitive
solution to the problem is needed for the correct replica location.
May 16th, 2000 J. Apostolakis
G4PropagatorInField[.hh.icc]:
- Added implementations for SetDeltaOneStep and SetDeltaIntersection.
May 9th, 2000 J. Apostolakis - geomvol-V01-01-00
Improvements in G4PropagatorInField incorporating include file fixes
in geometry-V01-01-02
[ ie: Introduced kCarTolerance for check over taken step length and
TruePathLength in G4PropagatorInField::ComputeStep(). ]
May 8th, 2000 J. Apostolakis - geomvol-fieldImprove1
Internal tag for version that improves the behavior of the field.
[ it does not include the changes of geometry-V01-01-02 ]
May 5th, 2000 J. Apostolakis
G4PropagatorInField improvements modifying:
i) the comparison for detecting probable loop condition
- to accomodate solids that (wrongly) return small finite answer instead
of zero for Distance on surface. [ can probably be reversed eventually]
ii) the condition for exit from while (sufficient path length) to
avoid making a very small final step : used the tolerance.
April 25th, 2000 G. Cosmo
- Reorganised comments for the Software Reference Manual.
- Moved inlined definition to .icc files, where needed.
Created: G4LogicalBorderSurface.icc and G4LogicalSkinSurface.icc.
- Removed obsolete G4Transform class. Removed files:
G4Transform[.hh.icc].
January 19th, 2000 G. Cosmo - geomvol-V01-00-00
Sycronized files versions with HEAD after ISO-C++ migration.
(essentially CVS headers changes). Left out only G4Navigator[.hh.cc].
December 2nd, 1999 G. Cosmo - geomvol-V00-01-02
G4TransportationManager: Fixed definition of the singleton to conform
to the canonical implementation. Moved default constructor from private
to protected and added call to G4Exception in case of multiple instances
through derived classes.
November 26th, 1999 J. Apostolakis - geomvol-V00-01-01
G4TouchableHistory: Moved GetTranslation and GetRotation from inline file
to source file -- as they use static variables in the methods themselves.
--> cannot be handled by new HP aCC compiler
G4PropagatorInField: Initialised fVerboseLevel in constructor. (omision)
--> on WinNT 4.0sp4 / VC++ 6.0 it was given value of 1 not 0.
November 10th, 1999 J. Apostolakis - geomvol-01-01-01b
Modified test/GNUmakefile to make it use fully-granular libraries.
New test code in testG4Volumes for Object/Frame Rotation/Translation.
October 29th, 1999 J. Apostolakis - geomvol-01-01-01a
Moved initialisation of static data members of G4PropagatorInField
fDefault_Delta_Intersection_Val
fDefault_Delta_One_Step_Value
to G4TransportationManager.cc, to ensure correct order initialisation
of static (class) data members
G4PropagatorInField warning message about integration inaccuracy
now printed (for a maximum of 10 times) and in Verbose.
July 27th, 1999 J. Apostolakis - geomvol-01-01-02
Modified G4Navigator to distinguish Candidate volume from Blocked volume
July 27th, 1999 J. Apostolakis - geomvol-01-01-01
Tagged --- here ??? ---
July 27th, 1999 J. Apostolakis
G4PropagatorInField:
Added instance variables to keep track of "abnormal" case - which caused loop:
This is induced when a step at a boundary goes into one volume
- but in that volume it encounters an intermediate boundary
and when the step is subdivided it finds a zero step.
Then it looped between the volumes
This is corrected by finding this problem (#subsequent zero steps > threshold)
and attempting ever smaller trial steps until it succeeds.
-> it was not done for the first step
July 27th, 1999 J. Apostolakis
G4PropagatorInField:
Made DeltaIntersection and DeltaOneStep instance variables (not class var.)
Added Get/Set methods. Old values of are now the defaults.
July 1st, 1999 J. Apostolakis - field-01-00-06a
In G4PropagatorInField --> method LocateIntersectionPoint():
Integration inaccuracies cause an internal step's mid-point and endpoint
to be further apart than their curve length difference. (Unphysical)
In order to compensate, we re-compute the step's endpoint. [ This also
requires modification in G4ChordFinder::ApproxCurvePointV ]
A better solution would be to re-start/re-structure the loop to handle this
sort of case. But this would be a more major change ...
May 19, 99 J.Apostolakis, F. Behner
In G4Navigator: Changed cout -> G4cout
Changed protection for printing of Physical volume name:
(because of warning on SUN; same functionality)
In G4NavigationLevel, created an optional operator delete(void *, void *)
this is accepted by DEC, and not accepted by SUN, HP
new flag created in architecture for protection: ~ G4NO_ISO_DELETES
May 17, 99 J. Allison.
In G4NavigationLevel, changed operator new(size_t, G4NavigationLevel *)
to operator new(size_t, void *) because the former is not accepted
by Sun CC 4.2 (with STL Interface.)
May 3, 99 J. Apostolakis
testG4ReplicaNavigation.cc
Changed comparison of doubles, to give it a tolerance.
April 8, 99 (committed & recorded J. Apostolakis May 3rd)
G4NavigationLevel.{hh,icc}: Minor Changes
added const to copy constructor and
new 'new' operator with size_t - for STL use with preallocated containers"
March 19, 99 J. Apostolakis geomvol-01-00-03
New tag for replica fix.
March 18, 99 J. Apostolakis
A fix for looping in Replicas:
In the case where a zero step is done in Replicas, we must allow
ReplicaNavigator to handle the case itself - or else we loop.
March 11, 99 J. Apostolakis
G4GRSVolume.icc: corrected G4Exception messages.
February 18, 99 J. Apostolakis
include/G4VoxelNavigation.hh
src/G4VoxelNavigation.cc : overwrote versions 1.2 with production version
---> when changes are refined and retested, they could be reincorporated
February 17, 99 J. Apostolakis geomvol-01-00-02
Moved G4PropagatorInField here from magneticfield to remove correct
dependency.
February 15, 99 J. Apostolakis geomvol-01-00-01
Only fixes in G4Navigator's incorporated.
GNUmakefile corrected (for SUN-CC).
January 99, J. Apostolakis
Fix for ComputeSafety in Navigator: G4Navigator.cc
the voxel information that was used was incorrect v 1.3
-> it resulted in wrong value of safety
December 98 geant4-00-RandD
include/G4VoxelNavigation.hh
src/G4VoxelNavigation.cc : versions 1.2 are trial versions from beta "head"
