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 directory-tags.
It DOES NOT substitute the CVS log-message one should put at every
committal in the CVS repository !

now correctly written: scene.AddThis(*this).
Apr 05, 00 G. Cosmo geom-solids-csg-V01-01-01

into compliance with specifications (D.Williams)
- Moved to "specific" the following classes:
G4ClippablePolygon, G4EnclosingCylinder, G4Hype, G4PolyPhiFace,
G4Polycone, G4PolyconeSide, G4Polyhedra, G4PolyhedraSide,
G4ReduciblePolygon, G4IntersectingCone, G4SolidExtentList,
G4VCSGface, G4VCSGfaceted.

- Tagged.
Mar 22, 00 D. Williams
- G4PolyhedraSide.cc: fixed bug in G4PolyhedraSide::Normal(...).
The method Normal(...) (used by G4VCSGfaceted::SurfaceNormal) was not
filling in the argument bestDistance. This fixes a bug observed in
G4Polyhedra::SurfaceNormal.

to avoid warnings on Linux.
Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04

testG4Trap.cc. (V.Grichine)

in CSG solids --> Problem report from D.C. Williams, BaBar
- A check in G4Trap Makeplane added.
Nov 10, 99 J. Apostolakis geom-solids-csg-01-00-02-cand
- Included David Williams' modifications to
G4IntersectingCone.cc, G4PolyconeSide.cc and G4VCSGfaceted.cc
and to test/SBT/SBT.cc and test/SBT/polycone.geant4

May 18, 99 David Williams
- Replaced 1/DBL_MAX with DBL_MIN (valid correction, seen in tests for STL)
in G4PolyPhiFace.cc, G4PolyconeSide.cc and G4PolyhedraSide.cc
Apr 29, 99 David Williams
- G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified:
1. Implemented correct copy constructors and assignment operators.
2. Fix some leaks for tracks that pass exactly through an edge.
Some leaks still remain: particularly if a track passes through
a corner and between the curved edges of G4Polycone.
3. G4Polyhedra argument numSide changed to G4int (from G4double)
Apr 13, 99 Vladimir Grichine and Simone Giani
- Minor consistency fix to 8 basic CSG solids:
Tolerance used in calculation of extent but not in one place,
and not another - this tripped up the client code.
Feb 16, 99 David Williams
- Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in
test/testG4Polycone and missed in below.
- Updated definition of DistanceToIn(p) and DistanceToOut(p) to
return zero when the point p is on the surface of the solid.
Feb 12, 99 David Williams
- src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by
test/testG4Polycone.
Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu)
- I've committed new versions of the CSG Polycone and Polyhedra in the
geant4 repository, including a new utility class called
G4ReduciblePolygon. The new versions fix several subtle bugs which my
"test3" batch geometry testing code uncovered. In addition, the new class
G4ReduciblePolygon is used to run strict tests on the validity of input
parameters.
To fix a bug in Polyhedra, I had to back out some fancy code that
allowed it to calculate intersections at a speed that was independent of
the number of sides. The new version now runs at a speed proportional to
the number of sides, and is thus much slower for polyhedras with many
sides. I can fix this, but I thought it would be best to get the bug fixes
in as soon as possible.
