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 !

G4Box: Changed DistanceToIn to fix new problem.
G4ParameterisedNavigation
G4VoxelNavigation
Fixed VoxelSafety computation for the case of the middle voxel of
a set of equivalent (lowest-level) voxels.
Sept 17th, 98 John Apostolakis geometry-00-03-01
Tag created.
Sept 15th, 98 John Apostolakis
In G4ParameterisedNavigation
i) Corrected ComputeSafety(...) which called ComputeVoxelSafety without
setting the fVoxelNode & fVoxelNodeNo to the ones at localpoint.
[ This produced incorrect safeties in some cases & resulted in an
assertion failure in testT08 because of an unexpected change of volume. ]
ii) ComputeStep: Fixed assertion check of blocked replica number.
Aug 24th, 98 John Apostolakis geometry-00-02-01
Tagged.
Small fixes in BREPS, to allow compilation on different platforms.
==============================================================================
beta01 release
==============================================================================
July 31st, 98 Peter Urban
Several fixes for BREPS.
July 29th, 98 John Apostolakis (with Stefano Magni)
G4BREPSolidPCone.cc : Cylindrical sections were incorrectly placed.
G4ConicalSurface.cc
G4CylindricalSurface.cc:
The Inside functions are modified to try to use the Geant-4 tolerance.
--> must be checked further
[ The method is used by Intersect of respective surfaces in a
complicated manner. ]
G4FConicalSurface.cc
- Fix to Bounding Box, which was incorrectly centered/placed.
- Fix to Intersect, to insure that only intersection in Finite extent of
Surface are found.
July 28th, 98 John Apostolakis
In the Navigator location, the blocked Volume was not cleared when the
navigator descended several levels in the tree. This would allows the same in another part of the tree to be wrongly blocked.
In G4ParameterisedNavigation, the identity of the blocked Physical Volume
was not checked! You would block replica number 3 of your parameterised volume
although you exited replica number 3 of another volume!
The above problems combined to allow BlockingList to be
called with replicaNo = -1, which caused Linux/G++ & HP to dump core
on program exit.
Modified Files:
G4Navigator.cc
G4ParameterisedNavigation.cc
An assignment used to be an equality check by mistake. (Probably it was ok
because it is redundant)
Modified Files:
G4VoxelNavigation.cc
July 23rd, 98 John Apostolakis
June 26th, 98 John Apostolakis geometry-00-06-05
1) Modified check in ComputeStep that pseudo-relocation is within safety:
i) no check is made is the move is within tolerance as it makes no sense
- on a boundary it would cause a volume change (where there was none.)
ii) the Navigator now stores the last safety it calculated (origin, value)
and uses it for the calculation of this check.
This eliminates problems with this check, that produced assertion
failure in many example codes.
2) NavigationHistory equality operator modified for efficiency (with P.Urban)
3) G4Box Problem in DistanceToIn reporting intersection where there was
none has been given a more complete solution (V.Grichine)
G4Sphere Exception problem fixed. (V.Grichine)
June 20th, 98 John Apostolakis geometry-00-06-04
1) I have added a check that any pseudo-relocation made between a
call to Locate (the true Relocation) and the next call to ComputeStep
(eg in a PostStepDoIt) is truly within safety.
2) The Navigator's ComputeStep method now always returns infinity, when it
does not limit the step
3) G4Tubs.cc: Fixed surface normal (in R) which was not a unit vector.
June 18th, 98 John Apostolakis
In the Navigator:
1) Fix to allow lateral displacement (within safety) in PostStepDoIts
without messaging the Navigator.
2) A first implementation of LocateGlobalPointWithinVolume
A fix in NormalNavigation's Compute Step, to allow volumes that are "touched"
to be tagged as entered. (Ie, if the step is just long enough to arrive at
the surface of a volume, the navigator can still enter it quickly.)
June 12th, 98 John Apostolakis (geometry-00-06-03)
Candidate fix to BREP PCone, constructing Conical Surfaces using different
starting point.
Fix to ReplicaNavigation to temporarily patch "assertion" problem.
June 10th, 98 John Apostolakis (geometry-00-06-02)
Added a new CSG Solid (G4Hype), a Hyperboloid by rotation
Bug fix to G4Box::DistanceToIn (which reported intersection where there
was none).
Bug fix to G4FConicalSurface and G4ConicalSurface to fix G4BREPSolidPCone.
Correction to to DistanceToOut of BREPSolid to ensure compatibility with
convexity assumptions of Navigator
June 8th, 98 John Apostolakis (geometry-00-06-01)
Created a tag for BREPS at the last point before merge with Peter's Developments.
Modified
G4Navigator and
G4NormalNavigation G4ParameterisedNavigation
G4ReplicaNavigation G4VoxelNavigation
to add ComputeSafety methods. These make a quick estimation of the
safety and can/should be called for the final point of a step only.
June 3rd, 98 John Apostolakis
G4Navigator:
Added a new new method LocateGlobalPointWithinVolume that serves to notify
the Navigator that a track has moved to the new Global point 'position'.
This point must be known to be within the current volume, probably because it
is withing safety.
May 11th, 98 John Apostolakis
G4PVPlacement:
- Implemented additional (4th) constructor that takes a pointer to a
logical mother volume and a G4Transform3D with the solid's rotation.
- Also added a data member to store whether a RotationMatrix was created.
This allows us to avoid a small memory leak in use of 2 constructors.
May 8th, 98 John Apostolakis
- History files created in magneticfield directory for this category.
It will be used exclusively for the maintenance of information in
this category. Only what impacts its interaction with the geometry
(G4PropagatorInField) will be mentioned here.
- History file has existed in solids/BREPS for slightly more detailed
changes in that sub-category.
April 29th, 98 John Apostolakis (geometry-00-05-05)
- A significant logical error in G4VoxelNavigation::LocateNextVoxel was
corrected: the search for the next voxel could ignore voxels at lower levels
- Small changes for DEC in GNUmakefile in BREPS & STEP
* Removed -cfront option from GNUmakefile for DEC. -cfront
overrides ANSI standard rules in cxx-6.0.
* Cleaned up trivial warnings on DEC (Extraneous semicolons).
April 27th, 98 John Apostolakis (geometry-00-05-04)
- Tagged
April 24th, 98 Jari Sulkimo ( recorded by John Apostolakis here)
- Fixes in BREPs (see solids/BREP/History for details, by author)
* fixed scope bugs in for loops
* bug fixes to G4Assembly.cc for STEP file interaction & placed solids
creation.
April 23rd, 98 John Apostolakis (geometry-00-05-03)
- Bug fixes to BREP code for Assembly level of STEP files
(introduced in alpha05)
- Renamed file G4Point3d.hh to G4Point3d.h (because of problems
on Windows NT in name clash with G4Point3D.hh).
April 22nd, 98 John Apostolakis (geom-05-02)
- Tagged.
April 21st, 98 John Apostolakis (geometry-00-05-01)
- Added SetAllParameters methods to G4Torus and G4Para.
- All CSG solids now inherit from the new abstract class G4CSGSolid, instead
of directly from G4VSolid.
- "const G4double" arguments have been changed to "G4double" for CSG methods.
April 21st, 98 John Allison
- Slightly relaxed tolerance in G4Trap (for g3tog4).
- Corrected G4BREPSolidPolyhedra.cc for graphics_reps/G4Polyhedron.
- Added void G4Trd::SetAllParameters.
- Also relaxed check in G4Trd::CheckAndSetAllParameters (pdx1>=0, etc.)
April 2, 98 G.Barrand
- STEP/dirobj.cc : #ifdef WIN32, do not compile opendir and closedir.
March 24, 98 G.Barrand
- GNUmakefile : MAKESHLIB changed in G4MAKESHLIB
March 13, 98 G.Cosmo (on behalf of S.Giani) - (geometry-00-04-05)
- Added G4VPVParameterisation.cc including default implementations
of ComputeSolid() and ComputeMaterial() missing previously (J.Apostolakis).
- Included fixes for aCC compiler in BREPS and STEP (J.Sulkimo, G.Cosmo).
March 9, 98 J. Apostolakis - (geometry-00-04-04)
- Small fix to G4BREPSolid.cc which was causing problems on HP-UX.
(Deleted use of floating point modulo for integers, with Jari S.)
- G4Sphere: further small corrections.
March 5, 98 J. Apostolakis - (geometry-00-04-03)
- Parameterised Volume can now VARY the TYPE of SOLID and/or Material
by copy number. PVParameterisation classes can now compute these.
The Navigator has been modified to compute solid and material, and
to set them in the associated logical volume
- Now able to process an extra level of STEP files, using new code in
BREPs (Jari Sulkimo).
- Further cleanup of code in BREP category (Peter Urban).
- Small modification in solids/STEP/GNUmakefile for Win/NT port (S. Sadilov).
March 4, 98 J. Apostolakis - (geometry-00-04-02)
- G4Sphere: corrected tests of the phi angle and with tolerance checking
that compared squares of distances.
- The World volume can now be split into replicas. This not recommended, but
the Navigator is now able to handle it.
- Cleanup of code in BREP category (Peter Urban & Jari Sulkimo)
February 16, 98 J. Apostolakis - (geometry-00-04-01)
- Replicas and parameterised physical-volumes now store the copy number of
their current copy. (It is valid only for physical volume in the hot tree).
Navigation routines were modified to enable this.
February 4, 98 J. Apostolakis - (geometry-00-03-02)
- A few small changes were made to the Magnetic Field classes.
This included one that allows it to work without repeatedly
issuing an unneccessary warning.
- Small fixes to BREP and STEP parts help in fixing a problem
with True/false on some platforms.
January 28, 98 S. Sadilov
- Small modification in GNUmakefile for Win/NT port
January 26, 98 J. Apostolakis - (geometry-00-03-01)
i) New implementation of G4NavigationHistory using G4NavigationLevel.
This implementation allows for very fast copying of G4NavigationHistory,
which is required in order to copy G4TouchableHistory.
ii) Correction in G4ReplicaNavigation.cc in DistanceToOutPhi, influencing
replicas divided in phi.
December 19, 97 G. Cosmo - (alpha03)
- Created.
