They are treated now in both functions in terms of kAngTolerance.
The reason is that historically SurfaceNormal(p) was using only
kCarTolerance for estimation of shortest distance to a surface. Now,
following the new updated specification, the surface selection is made
according to Inside(p) approach (as kSurface is selected), i.e. - for
phi/theta surfaces in terms of kAngTolerance.

- Removed implementations of GetExtent in most sub-classes of G4VSolid (a
default implementation exists in G4VSolid).
- All implementations of DescribeYourselfTo (G4VGraphicsScene& scene) const
now correctly written: scene.AddThis(*this).
Apr 05, 00 G. Cosmo geom-solids-csg-V01-01-01
- G4Tubs.cc: fixed bug in function Inside(p).
Removed (commented) in the code umproper addition of 2PI
to Phi-angle particle (V.Grichine)
- G4Hype[.hh.cc]: fixed several longstanding issues and bring methods
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.
- Moved testG4Hype.cc and testG4Polycone.cc from CSG/test to
specific/test
- Moved generic tests "SBT" and "Fred" one level up to solids/test.
- Organised class description comments for the Software Reference Manual
in all headers.

- 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.
Mar 14, 00 V. Grichine
- Added diagnostics in G4Cons, G4Sphere and G4Torus in function
DistanceToOut(p,v,...).
Mar 03, 00 G. Cosmo geom-solids-csg-V01-00-05
- Minor fixes to unit tests to make them up-to-date with recent
development versions (already included in tag geometry-V01-00-00a).
- G4PolyconeSide.cc, G4PolyhedraSide.cc: added explicit cast to G4int
to avoid warnings on Linux.
Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04
- Fixed bug in DistanceToIn(p,v). Modified files: G4Trap.cc and
testG4Trap.cc. (V.Grichine)
- Syncronized file versions with HEAD (essentially CVS headers changes).
- Fixes for missing migration on HEAD related to some files in test/fred
and test/SBT.

- Added initialisation to Eside "side" variable in DistanceToOut(p,v)
in CSG solids --> Problem report from D.C. Williams, BaBar
- A check in G4Trap Makeplane added.

- Included David Williams' modifications to
G4IntersectingCone.cc, G4PolyconeSide.cc and G4VCSGfaceted.cc
and to test/SBT/SBT.cc and test/SBT/polycone.geant4

- 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.
