 Jun 12, 2003   G.Cosmo                   geom-bool-V05-01-02
  - G4ReflectionFactory:
    o Made public accessors: GetConstituentLV(), GetReflectedLV(),
      IsConstituent() and IsReflected().
    o Added accessor GetReflectedVolumesMap() to access list of
      reflected volumes.

 May 22, 2003   G.Cosmo                   geom-bool-V05-01-01

 Jan 27, 2003   G.Cosmo                   geom-bool-V05-00-00
  - G4ReflectionFactory[.hh.cc] (courtesy of I.Hrivnacova):
    o Added set/get functions Set/GetVolumesNameExtension() for volume-name
      extension. By default now the factory assigns "_refl" postfix to name
      of reflected volumes.
    o Assumed less strict condition in the CheckScale() method, to avoid
      precision problems with imported rotation matrices.

 Oct 29  2002  Gabriele Cosmo       geom-bool-V04-01-01
  - Added method CleanTransformations() to G4DisplacedSolid and corrected
    implementation in destructor of G4BooleanSolid to not call for deletion
    of G4VSolid in the case where displacement is used.
    This fixes a problem noticed on Linux-g++ at application closeout for
    double deletion of a solid in such special case.

 Oct 28  2002  Gabriele Cosmo       geom-bool-V04-01-00
  - Added implementation of StreamInfo() to comply with new interface for
    G4VSolid in "geommng-V04-01-03".
  - Some cosmetic changes to code formatting.
  - Extended unit tests to include new user test-cases (V.Grichine).

    passing all basic unit tests.

    G4ReflectionFactory for reflections of positioned volumes
    (courtesy of V.Grichine and I.Hrivnacova).
  - Fixed bug in G4ReflectedSolid::CreatePolyhedron().

 Aug 13  2001  Vladimir Grichine    geom-solid-bool-V03-02-00
  - Introduced G4BOOLDEBUG flag and replaced G4Exception statements with
    simple warnings to G4cerr for rare occurences of anomalous conditions.

 May 30  2001  Vladimir Grichine    geom-solid-bool-V03-01-00

    in problem report #153.

 Mar 19  2001  Gabriele Cosmo       geom-solid-bool-V03-00-03

  - G4IntersectionSolid:
    o fix in CalculateExtent() for computation of pMin and pMax, to avoid
      assignment in case CalculateExtent() of one component solid fails.
    o fix in Inside() to return kOutside in case first component solid's
      Inside() returns kOutside.
  - G4UnionSolid:
    o fix in CalculateExtent() for computation of pMin and pMax: initialised
      local variables.

 Jan 31  2001  Gabriele Cosmo       geom-solid-bool-V03-00-02

  - Fix in G4UnionSolid::DistanceToOut(p,v,...) for assignment of
    argument *n. Previous fix was incomplete!

 Jan 23  2001  Gabriele Cosmo       geom-solid-bool-V03-00-01
 
  - Fixed wrong labels for G4Exception calls in G4UnionSolid.cc and
    G4SubtractionSolid.cc to identify the correct class.

 Jan 08  2001  Vladimir Grichine    geom-solid-bool-V03-00-00

  - Fix in G4UnionSolid::DistanceToOut(p,v,...) for assignment of
    argument *n to happen only if calcNorm is false.
    (courtesy of D.Williams)
  - Updated unit tests testG4IntersectionSolid.cc, testG4SubtractionSolid.cc
    and test/testG4UnionSolid.cc.

 Nov 22  2000  Vladimir Grichine    geom-solid-bool-V02-00-03

  - Added new set methods for matrix/vectors to G4DisplacedSolid:
      SetTransform(G4AffineTransform&),
      SetDirectTransform(G4AffineTransform&),
      SetFrameRotation(const G4RotationMatrix&),
      SetFrameTranslation(const G4ThreeVector&),
      SetObjectRotation(const G4RotationMatrix&),
      SetObjectTranslation(const G4ThreeVector&).

 Nov 20  2000  Gabriele Cosmo       geom-solid-bool-V02-00-02

 Sep 13  2000  Vladimir Grichine    geom-solid-bool-V02-00-00

  - G4SubtractionSolid.cc: relaxed behavior in SurfaceNormal(p), where
    it is allowed for a point to be inside the solid. A message is thrown
    to cerr instead of a G4Exception.

 Jun 26  2000  Vladimir Grichine    geom-solid-bool-V01-01-03

  - Fixed bug in G4SubtractionSolid::DistanceToOut(p,v,...). validNorm
    flag was uncorrectly set to true. Fixes report #102.

 Jun 6   2000  John Apostolakis     geom-solid-bool-V01-01-02

  - Protecting the use of pointers validNorm and n, if calcNorm is false

 Jun 6   2000  John Allison         geom-solid-bool-V01-01-01

  - Re-enabled CreatePolyhedron() method from G4UnionSolid, G4IntersectionSolid
    and G4SubtractionSolid.  Coworks with greps-V01-01-04.

 May 26  2000  John Allison         geom-solid-bool-V01-01-00

  - Disabled CreatePolyhedron() method from G4UnionSolid, G4IntersectionSolid
    and G4SubtractionSolid. It now temporarly returns a NULL pointer.
    Visualisation of Boolean solids is therefore temporarly disabled, pending
    a definitive fix in graphics_reps.
    Files G4UnionSolid.cc, G4SubtractionSolid.cc and G4IntersectionSolid.cc
    are included in the branch-tag "boolean_nopoly_branch".

 Apr 27  2000  Gabriele Cosmo

  - Reorganised comments for the Software Reference Manual.
  - Added CVS headers and standard G4 header where missing.

 Apr 11  2000  John Allison

  - CreatePolyhedron implemented for BooleanSolids.
  - G4DisplacedSolid: reversed implementation of GetFrameRotation and
    GetObjectRotation, removing inappropriate invertion.
  - G4DisplacedSolid::GetConstituentMovedSolid() made const.

 Jan 19  2000   Gabriele Cosmo      geom-solid-bool-V01-00-00

  - Syncronized file versions with HEAD (essentially CVS headers changes)
  - Fixed cases of G4std::min which were not migrated on the HEAD in files:
    G4UnionSolid.cc and G4IntersectionSolid.cc

 Nov 24  1999                       geom-solid-bool-V00-01-05

  - Small fix in src/G4DisplacedSolid.cc to the return type 
         (const G4AffineTransform --> G4AffineTransform)
    to conform with the specification of the class.

 Nov 19  1999                       geom-solid-bool-V00-01-04

  -  Fixes from Vladimir, and additional tests

 Nov 10  1999                       geom-solid-bool-V00-01-03b

  - Renamed  GetConstituentSolid to GetConstituentMovedSolid in G4DisplacedSolid
     to avoid clashing with method that gets the contituents of a G4BooleanSolid.

 Nov 10  1999                       geom-solid-bool-V00-01-03a

  - Tag with additional methods for Persistency

 Nov 10  1999                       geom-solid-bool-V00-01-03-cand

  New method: Get Object Rotation/Translation methods in Displaced Solid

 Nov  9  1999                       geom-solid-bool-V00-01-02-cand
  
  - Tag with additional methods for Visualisation

   G4DisplacedSolid,  G4BooleanSolid

      Added methods to access data members:
          Get Constituent Solid  (int) for Boolean   Solid 
          Get Constituent Solid        for Displaced Solid 
          Get Frame Rotation/Translation methods in Displaced Solid



  Dec  1  1998   John Apostolakis   geom-boolean-4-ja

    Code portability changes.

  Nov 27  1998   J.Apostolakis & V.Grichine   geom-boolean-3-vg

    Fixes agreed in code review were implemented.
