222 to be not inline.
223 - Restored also non-inline constructors/destructors for G4NavigationHistory
224 and G4NavigationLevel (the last apparently responsible for crashes on SLC5
225 in the allocation).
226
227 November 3rd, 2014 G.Cosmo - geomvol-V10-00-07
228 - Moved constructors, destructors and assignment operators for

350 G4LogicalBorderSurface and G4LogicalSkinSurface.
351
352 February 12th, 2013 J.Apostolakis - geomvol-V09-06-00
353 - G4TouchableHistory: inspected changes for Geant4-MT.
354 Took out unneeded calls that initialised allocator in many methods.
355 Only the call in new() is needed, and is kept.
356 Cleared extra code introducing a performance penalty and also complicating
357 the code without reason.
358 Note: constructors cannot check that the Allocator is initialised.
359 They could be called first to create an object which was created
360 in a different way (e.g. on the stack, via new(prealloc) or new[ ] ).
361

381 - Defined scheme for warnings/errors coding:
382 + 1xxx for warnings, 0xxx for errors.
383 Code numbering:
384 + 0001: not supported or implemented features;
385 + 0002: invalid setup/construct;
386 + 0003: invalid run condition;
387 + 1001: incorrect setup; automatically adapted.
388 + 1002: notification.

431 locality.
432
433 Dec 11th, 2009 G.Cosmo - geomvol-V09-03-00
434 - Use G4Allocator for vectors in G4NavigationHistory, to optimise memory
435 management and reduce fragmentation.
436
437 Nov 6th, 2009 G.Cosmo - geomvol-V09-02-04

710 *************************************************************************
711 * Changed default value of "maximum step count" to 1,000 (from 10,000) *
712 * --> this may cause more particles to be recognised to loop earlier, *
713 * as this parameter controls this too. *
714 *************************************************************************

719 so as to have it updated when the global field manager is changed.
720 3) Added new state variable to insure that the current field Manager
721 has been set for the current step
722 The flag ensures that the method FindAndSetFieldManager() is always
723 called once for each call to ComputeStep().

874 May 15th, 2002 G. Cosmo - geomvol-V04-00-07
875 - G4ParameterisedNavigation:
876 o Introduced 3D voxelisation technique for parameterised volumes with
877 unspecified axis. Changed to become subclass of G4VoxelNavigation and
878 adopt the same voxel location algorithms for optimised navigation.
879 - G4VoxelNavigation:
880 o Changed to become base class for optimised navigation.
881 o Cosmetics and reformatting.
882 - G4NormalNavigation.icc, G4ReplicaNavigation.icc, G4VoxelNavigation.icc:
883 o Minor optimisations.
884 o Cosmetics and reformatting.
885 - G4Navigator.cc:
886 o Invoke specific VoxelLocate call for parameterised navigation.
887 - Co-works with "global-V04-00-06" and "geommng-V04-00-05".
888
889 Apr 19th, 2002 G. Cosmo - geomvol-V04-00-06
890 - Moved inline constructors and destructors to no inline.
891 Affected files: G4BlockingList[.icc,cc], G4NavigationHistory[.icc,.cc],
892 G4PropagatorInField[.hh.icc.cc].
893
894 Apr 3rd, 2002 G. Cosmo - geomvol-V04-00-05
895 - G4GeometryMessenger[.hh.cc]: added new commands to exploit more features of the
896 G4GeomTestVolume class for detecting geometry overlaps:
897 o /geometry/test/grid_test - runs the default grid test, same as "run".
898 o /geometry/test/recursive_test - runs the grid test in recursive mode.
899 o /geometry/test/cylinder_test - to shoot lines in a cylindrical pattern.
900 o /geometry/test/line_test - to shoot a line according to position and direction.
901
902 Mar 22nd, 2002 J. Apostolakis - geomvol-V04-00-04
903 - G4PropagatorInField: added Set/Get methods for MaximumEpsilonStep
904
905 Feb 20th, 2002 G. Cosmo - geomvol-V04-00-03
906 - G4GeometryMessenger.cc: fixed local variable name not to clash with
907 class data member.
908
909 Jan 21st, 2002 J. Apostolakis - geomvol-V04-00-02
910 - G4Navigator: reset blocked volume when locating 'within volume',
911 after ensuring that it does not get called when
912 ComputeSafety() is at a boundary.
913 --> Fix for cases of longstanding 'Point P is Inside' errors.
914
915 Jan 10th, 2002 G. Cosmo - geomvol-V04-00-01
916 - Activated mechanism in GNUmakefile for allowing compilation with
917 G4DEBUG_FIELD or G4DEBUG_NAVIGATION flags. Replaced DEBUG with
918 G4DEBUG_NAVIGATION in G4Navigator.cc.
919
920 Jan 8th, 2002 J. Apostolakis - geomvol-V04-00-00
921 - G4AuxiliaryNavServices
922 o Fixed it so that it only considers whether a (Point,Direction) 'ray' if
923 it is on the surface (it was mistakenly also checking those inside, and
924 rejecting them.)
925 [ This erroneous condition occurred frequently in the new usage of Locate
926 with Direction to initialise a step.
927 It's unclear if it occurred also at other times.]
928
929 Jan 8th, 2002 G. Cosmo
930 - Fixed compilation problems and warnings on unit tests.
931 (G.Cosmo, R.Chytracek)
932
933 Dec 11th, 2001 G. Cosmo - geomvol-V03-02-08
934 - G4Navigator:
935 o Added kNormal and Copy Number to NewLevel (Navigation Level) for
936 Normal Navigation
937 Now all TouchableHistory objects should have a valid entry in ReplicaNumber:
938 - in the case of a placement volume it will be the copy number
939 - in replicated volumes it will be the replica number
940 o Commented out fix introduced in geomvol-V03-02-05.
941
942 Dec 11th, 2001 J. Apostolakis - geomvol-V03-02-07
943 - G4Navigator:
944 o Undoing the fix in geomvol-V03-02-05 -- because of problems in
945 several tests (mostly large N tests).
946 ----> Must resolve these !! <----
947
948 Dec 8th, 2001 J. Apostolakis - geomvol-V03-02-06
949 - G4PropagatorInField:
950 o additional thresholds for No of steps, + get/Set methods
951 o Modified choice of subsequent step size in case of Zero step
952 - decrease quickly at first to try to ensure that the first/second
953 "re-steps" are enough in most cases.
954 - utilise addition threshold parameters (for # of steps)
955 to slow down the rate of decrease of the step size
956 for the 'difficult' cases which do not converse after
957 a few steps.
958
959 Dec 6th, 2001 J. Apostolakis - geomvol-V03-02-05
960 - G4Navigator:
961 Fix for Locate Global Point Within Volume: clear state
962 variables (that had erroneously been forgotten).
963
964 Dec 6th, 2001 R. Chytracek - geomvol-V03-02-04
965 - G4Navigator:
966 o Fixed mirroring of the input argument for global direction into
967 local variable in LocateGlobalPointAndSetup().
968 o Cosmetics for the Software Reference Manual in .hh file.
969
970 Dec 4th, 2001 J. Apostolakis - geomvol-V03-02-03
971 - G4Navigator:
972 o Modified the interface
973 - creating a new ResetState method (that only reset state - not stack)
974 - adding a new optional argument to LocateGlobalPointAndSetup method
975 - adding direction argument to LGPAS w/ touchable history
976 o Modified the implementation
977 - to reset its state when touchable history is used to re-initialise it
978 - to use the direction in LocateGlobalPointAndSetup methods!
979 - G4PropagatorInField:
980 o Added use of new Largest Acceptable Step data member.
981 o Protected, in reseting of Proposed Step length, against
982 making it bigger in cases where several zero steps seen.
983 o Several debugging prints added. (only in G4Verbose, ...)
984
985 Nov 28th, 2001 J. Apostolakis - geomvol-V03-02-02
986 - Added GetCurrentFieldManager method to PropagatorInField
987 - Incorporates additions seen in "geomvol-V03-02-00a/b/c"
988 and in "geomvol-V03-02-01".
989 - This tag is required by the new tag "transport-V03-02-06" in Transportation.
990
991 Oct 18th, 2001 J. Apostolakis - geomvol-V03-02-01
992 - Added a new 'maximum' epsilon value in G4PropagatorInField,
993 as some ill-conditions appear to be due to large proposed relative errors.
994 NOTE: does NOT include changes in "geomvol-V03-02-00a/b/c".
995
996 Nov 8th, 2001 G. Cosmo - geomvol-V03-02-00c
997 - Added handles for reference counting: G4GRSSolidHandle, G4GRSVolumeHandle,
998 G4TouchableHistoryHandle.
999 - Modified G4Navigator for reference counted touchables. Introduced new methods
1000 CreateTouchableHistoryHandle() and LocateGlobalPointAndUpdateTouchableHandle(...).
1001 - New unit tests testG4ParameterisedMaterial.cc and testG4TouchableHandle.cc.
1002
1003 Nov 1st, 2001 G. Cosmo - geomvol-V03-02-00b
1004 - G4GeometryMessenger.cc: fixed definition of unit category for tolerance.
1005
1006 Oct 24th, 2001 G. Cosmo - geomvol-V03-02-00a
1007 - Moved G4GeomTestMessenger from geometry/verification to geometry/volumes.
1008 Renamed to G4GeometryMessenger.
1009 - GeometryMessenger: renamed directory to geometry/test. Added directory
1010 geometry/navigator. Added geometry/navigator/reset command
1011 for resetting navigation history and position.
1012 - G4PropagatorInField.icc: fixed warning on Linux-g++....
1013
1014 Oct 18th, 2001 J. Apostolakis - geomvol-V03-02-00
1015 - Corrected the initialisation of fEpsilonMin in G4PropagatorInField
1016 constructor, which was forgotten.
1017
1018 May 31st, 2001 G. Cosmo - geomvol-V03-01-08
1019 - Fixed usage of 'fabs', which belongs to global scope, NOT in std
1020 namespace. Detected by compilation error on DEC ISO/ANSI setup.
1021 - G4VoxelNavigation.icc: initialised data-member in initialiser list of
1022 constructor with explicit initialisation to dummy values to allow porting
1023 on ObjecSpace STL.
1024
1025 May 23rd, 2001 J. Apostolakis - geomvol-V03-01-07
1026 - Added methods to Set the minimum epsilon (relative accuracy) to
1027 Propagator In Field.
1028
1029 May 23rd, 2001 J. Apostolakis - geomvol-V03-01-06
1030 - Added new parameter to Propagator In Field,
1031 fEpsilonMin which is the minimal relative accuracy for MF driving.
1032
1033 May 23rd, 2001 J. Apostolakis - geomvol-V03-01-05
1034 - Moved Delta Intersection and One Step from PropagatorInField to Field Manager.
1035 - Modified G4TransportationManager.cc to initialise default values accordingly.
1036 (Incorporating changes into a tag, finally, after fix to G4FieldManager
1037 constructors. )
1038 o This tag requires and co-works with field-V03-01-01.
1039 This now ENABLES the use of different Field Managers for different parts of
1040 the detector. First implementation allows a volume that has a field
1041 manager to override the global one.
1042 Note: All field managers currently must refer to fields in global coordinates
1043 o New ability: to set the delta accuracy parameters differently in different
1044 volumes (even while maintaining the same field as the global one!).
1045
1046 May 23rd, 2001 G. Cosmo - geomvol-V03-01-04
1047 - Fixes in G4ReplicaNavigation for bug reports #253 and #254:
1048 o in VoxelLocate(...), treated particular case of rotational symmetry
1049 with extent over 360 degrees (courtesy of H.Boie).
1050 o in DistanceToOutPhi(...), fix to correctly handle cases where the
1051 starting point is on boundary of replicas and direction is along boundary.
1052
1053 May 15th, 2001 G. Cosmo - geomvol-V03-01-03
1054 - G4AuxiliaryNavServices::CheckPointOnSurface(): added additional check to resolve
1055 endless looping of G4Navigator in case the track is passing through a point, edge
1056 or surface shared by two solids.
1057 This problem occured when G4Navigator was trying to transport a particle when
1058 exiting a solid. Transportation will now perform a few zero steps and continues
1059 stepping instead of looping around the same point. Fixes problem report #185.
1060
1061 April 27th, 2001 G. Cosmo - geomvol-V03-01-02
1062 - G4VoxelNavigation.icc: fixed compilation warnings on HP-UX, concerning
1063 potential uninitialised vector elements.
1064
1065 April 20th, 2001 G. Cosmo - geomvol-V03-01-01
1066 - Updated unit tests to conform to recent STL vector migration.
1067
1068 April 17th, 2001 G. Cosmo - geomvol-V03-01-00
1069 - Migration to STL vector:
1070 o Modified classes:
1071 G4VoxelNavigation, G4NavigationHistory, G4BlockingList,
1072 G4LogicalSkinSurface, G4LogicalBorderSurface.
1073 o Removed GetIndex() and table-index data from G4LogicalSkinSurface
1074 and G4LogicalBorderSurface.
1075
1076 March 19th, 2001 J. Apostolakis - geomvol-V03-00-03
1077 - G4PropagatorInField:
1078 Modified to use new (not obsolete) methods of G4FieldTrack.
1079 Deleted old/obsolete ComputeStep method
1080 (that was being used only for testing purposes, but
1081 could not be used anymore after change to Momentum Integration.)
1082
1083 March 12th, 2001 G. Cosmo - geomvol-V03-00-02
1084 - G4ReplicaNavigation::ComputeStep(): apply push of kCarTolerance to ourStep
1085 in case the proposed step is zero.
1086
1087 February 23rd, 2001 G. Cosmo - geomvol-V03-00-01
1088 - Restored original 0.5 shift for kPhi transformation in ComputeTransformation()
1089 methods, as original specifications from P.Kent impose.
1090 - Fixed bug in ComputeTransformation(const G4int rNo, G4VPhysicalVolume* pVol)
1091 where 'pVol' was NOT passed to SetPhiTransformation() in the kPhi case (!).
1092
1093 February 15th, 2001 G. Cosmo - geomvol-V03-00-00
1094
1095 - Fix in G4ReplicaNavigation::ComputeTransformation(...) for kPhi case.
1096 Removed shift of 0.5 to center of replica volume to conform with original
1097 specifications for replica transformations in Phi.
1098 - Cosmetics in G4ReplicaNavigation.cc.
1099
1100 November 20th, 2000 G. Cosmo - geomvol-V02-00-01
1101
1102 - Fixes to remove warnings from "-Wall -ansi -pedantic" g++ compiler options:
1103 o commented out variables declared and not used.
1104 o fixed declaration of variables used before being initialised.
1105 o fixed order of initialisation of member data in constructors.
1106 o fixed usage of unsigned-int (size_t) for array indeces.
1107
1108 November 1st, 2000 G. Cosmo - geomvol-V02-00-00
1109
1110 - QA code revision and cleanup (+fixes from CodeWizard filtering):
1111 o Added (private) copy constructor and assignment operator where needed.
1112 o Added "const" qualifier to accessor methods, wherever needed.
1113 o Added equality check on operator= where needed.
1114 o Made destructor "virtual" for classes having virtual methods,
1115 wherever missing.
1116 o Changed virtual functions to non-inline wherever's the case.
1117 o Changed return value to be "const" pointer to functions:
1118 - G4LogicalBorderSurface::GetVolume1()
1119 - G4LogicalBorderSurface::GetVolume2()
1120 - G4LogicalSkinSurface::GetLogicalVolume()
1121 o G4NavigationHistory: moved kHistoryMax and kHistoryStride to
1122 geomdefs.hh and made static constants. Reorganised comments.
1123 o G4VoxelNavigation: moved kNavigatorVoxelStackMax in geomdefs.hh.
1124 Changed "do-loops" with "while-loops" where convenient.
1125 o Added "inline" qualifier to methods' declarations.
1126 o General cosmetics
1127
1128 June 2nd, 2000 J. Apostolakis - geomvol-V01-01-02
1129
1130 include/G4PropagatorInField.hh,icc
1131 o Moved Delta Intersection and Delta One Step to FieldManager
1132 (from Propagator in Field), to allow them to differ over the detector.
1133
1134 G4TransportationManager.cc
1135 o Changed static variable for above (default values).
1136
1137
1138 May 17th, 2000 G. Cosmo - geomvol-V01-01-01
1139
1140 G4ReplicaNavigation.cc:
1141 - Added check to returned safety value in DistanceToOut(). Zero is
1142 returned if the computed velue is less than kCarTolerance.
1143 - Introduced temporary fix to ComputeStep() in the first step computation
1144 for replica boundaries. 'ourStep' is not set to the computed 'sampleStep'
1145 if 'sampleStep' happens to be zero.
1146 This fix helps to get rid of infinite loops when a point is on a
1147 shared surface of a replica or on a shared vertex; a more definitive
1148 solution to the problem is needed for the correct replica location.
1149
1150 May 16th, 2000 J. Apostolakis
1151
1152 G4PropagatorInField[.hh.icc]:
1153 - Added implementations for SetDeltaOneStep and SetDeltaIntersection.
1154
1155 May 9th, 2000 J. Apostolakis - geomvol-V01-01-00
1156
1157 Improvements in G4PropagatorInField incorporating include file fixes
1158 in geometry-V01-01-02
1159 [ ie: Introduced kCarTolerance for check over taken step length and
1160 TruePathLength in G4PropagatorInField::ComputeStep(). ]
1161
1162 May 8th, 2000 J. Apostolakis - geomvol-fieldImprove1
1163
1164 Internal tag for version that improves the behavior of the field.
1165 [ it does not include the changes of geometry-V01-01-02 ]
1166
1167 May 5th, 2000 J. Apostolakis
1168
1169 G4PropagatorInField improvements modifying:
1170 i) the comparison for detecting probable loop condition
1171 - to accomodate solids that (wrongly) return small finite answer instead
1172 of zero for Distance on surface. [ can probably be reversed eventually]
1173 ii) the condition for exit from while (sufficient path length) to
1174 avoid making a very small final step : used the tolerance.
1175
1176 April 25th, 2000 G. Cosmo
1177
1178 - Reorganised comments for the Software Reference Manual.
1179 - Moved inlined definition to .icc files, where needed.
1180 Created: G4LogicalBorderSurface.icc and G4LogicalSkinSurface.icc.
1181 - Removed obsolete G4Transform class. Removed files:
1182 G4Transform[.hh.icc].
1183
1184 January 19th, 2000 G. Cosmo - geomvol-V01-00-00
1185
1186 Sycronized files versions with HEAD after ISO-C++ migration.
1187 (essentially CVS headers changes). Left out only G4Navigator[.hh.cc].
1188
1189 December 2nd, 1999 G. Cosmo - geomvol-V00-01-02
1190
1191 G4TransportationManager: Fixed definition of the singleton to conform
1192 to the canonical implementation. Moved default constructor from private
1193 to protected and added call to G4Exception in case of multiple instances
1194 through derived classes.
1195
1196 November 26th, 1999 J. Apostolakis - geomvol-V00-01-01
1197
1198 G4TouchableHistory: Moved GetTranslation and GetRotation from inline file
1199 to source file -- as they use static variables in the methods themselves.
1200 --> cannot be handled by new HP aCC compiler
1201
1202 G4PropagatorInField: Initialised fVerboseLevel in constructor. (omision)
1203 --> on WinNT 4.0sp4 / VC++ 6.0 it was given value of 1 not 0.
1204
1205 November 10th, 1999 J. Apostolakis - geomvol-01-01-01b
1206
1207 Modified test/GNUmakefile to make it use fully-granular libraries.
1208 New test code in testG4Volumes for Object/Frame Rotation/Translation.
1209
1210 October 29th, 1999 J. Apostolakis - geomvol-01-01-01a
1211
1212 Moved initialisation of static data members of G4PropagatorInField
1213 fDefault_Delta_Intersection_Val
1214 fDefault_Delta_One_Step_Value
1215 to G4TransportationManager.cc, to ensure correct order initialisation
1216 of static (class) data members
1217
1218 G4PropagatorInField warning message about integration inaccuracy
1219 now printed (for a maximum of 10 times) and in Verbose.
1220
1221 July 27th, 1999 J. Apostolakis - geomvol-01-01-02
1222
1223 Modified G4Navigator to distinguish Candidate volume from Blocked volume

1228
1229 July 27th, 1999 J. Apostolakis
1230 G4PropagatorInField:
1231 Added instance variables to keep track of "abnormal" case - which caused loop:
1232
1233 This is induced when a step at a boundary goes into one volume
1234 - but in that volume it encounters an intermediate boundary
1235 and when the step is subdivided it finds a zero step.
1236 Then it looped between the volumes
1237
1238 This is corrected by finding this problem (#subsequent zero steps > threshold)
1239 and attempting ever smaller trial steps until it succeeds.
1240
1241 -> it was not done for the first step
1242
1243 July 27th, 1999 J. Apostolakis
1244
1245 G4PropagatorInField:
1246 Made DeltaIntersection and DeltaOneStep instance variables (not class var.)
1247 Added Get/Set methods. Old values of are now the defaults.
1248
1249
1250 July 1st, 1999 J. Apostolakis - field-01-00-06a
1251
1252 In G4PropagatorInField --> method LocateIntersectionPoint():
1253
1254 Integration inaccuracies cause an internal step's mid-point and endpoint
1255 to be further apart than their curve length difference. (Unphysical)
1256
1257 In order to compensate, we re-compute the step's endpoint. [ This also
1258 requires modification in G4ChordFinder::ApproxCurvePointV ]
1259
1260 A better solution would be to re-start/re-structure the loop to handle this
1261 sort of case. But this would be a more major change ...
1262
1263 May 19, 99 J.Apostolakis, F. Behner
1264
1265 In G4Navigator: Changed cout -> G4cout
1266 Changed protection for printing of Physical volume name:
1267 (because of warning on SUN; same functionality)
1268
1269
1270 In G4NavigationLevel, created an optional operator delete(void *, void *)
1271 this is accepted by DEC, and not accepted by SUN, HP
1272 new flag created in architecture for protection: ~ G4NO_ISO_DELETES
1273
1274 May 17, 99 J. Allison.
1275 In G4NavigationLevel, changed operator new(size_t, G4NavigationLevel *)
1276 to operator new(size_t, void *) because the former is not accepted
1277 by Sun CC 4.2 (with STL Interface.)
1278
1279 May 3, 99 J. Apostolakis
1280 testG4ReplicaNavigation.cc
1281 Changed comparison of doubles, to give it a tolerance.
1282
1283 April 8, 99 (committed & recorded J. Apostolakis May 3rd)
1284 G4NavigationLevel.{hh,icc}: Minor Changes
1285 added const to copy constructor and
1286 new 'new' operator with size_t - for STL use with preallocated containers"
1287
1288
1289 March 19, 99 J. Apostolakis geomvol-01-00-03
1290
1291 New tag for replica fix.
1292
1293
1294 March 18, 99 J. Apostolakis
1295
1296 A fix for looping in Replicas:
1297 In the case where a zero step is done in Replicas, we must allow
1298 ReplicaNavigator to handle the case itself - or else we loop.
1299
1300 March 11, 99 J. Apostolakis
1301
1302 G4GRSVolume.icc: corrected G4Exception messages.
1303
1304 February 18, 99 J. Apostolakis
1305
1306 include/G4VoxelNavigation.hh
1307 src/G4VoxelNavigation.cc : overwrote versions 1.2 with production version
1308 ---> when changes are refined and retested, they could be reincorporated
1309
1310 February 17, 99 J. Apostolakis geomvol-01-00-02
1311
1312 Moved G4PropagatorInField here from magneticfield to remove correct
1313 dependency.
1314
1315 February 15, 99 J. Apostolakis geomvol-01-00-01
1316
1317 Only fixes in G4Navigator's incorporated.
