132- Updated unit test testSurfaceNormal.cc.
133
134May 09, 2005 V.Grichine geom-csg-V07-00-04
135- Updated implementation of SurfaceNormal(p) to get consistence with
136 Inside(p) functions for the treatment of phi/theta surfaces.
137 They are treated now in both functions in terms of kAngTolerance.
138 The reason is that historically SurfaceNormal(p) was using only
139 kCarTolerance for estimation of shortest distance to a surface. Now,
140 following the new updated specification, the surface selection is made
141 according to Inside(p) approach (as kSurface is selected), i.e. - for
142 phi/theta surfaces in terms of kAngTolerance.
143

470- Removed implementations of GetExtent in most sub-classes of G4VSolid (a
471 default implementation exists in G4VSolid).

476 - G4Tubs.cc: fixed bug in function Inside(p).
477 Removed (commented) in the code umproper addition of 2PI
478 to Phi-angle particle (V.Grichine)
479 - G4Hype[.hh.cc]: fixed several longstanding issues and bring methods
480 into compliance with specifications (D.Williams)
481 - Moved to "specific" the following classes:
482 G4ClippablePolygon, G4EnclosingCylinder, G4Hype, G4PolyPhiFace,
483 G4Polycone, G4PolyconeSide, G4Polyhedra, G4PolyhedraSide,
484 G4ReduciblePolygon, G4IntersectingCone, G4SolidExtentList,
485 G4VCSGface, G4VCSGfaceted.
486 - Moved testG4Hype.cc and testG4Polycone.cc from CSG/test to
487 specific/test
488 - Moved generic tests "SBT" and "Fred" one level up to solids/test.
489 - Organised class description comments for the Software Reference Manual
490 in all headers.

496 - G4PolyhedraSide.cc: fixed bug in G4PolyhedraSide::Normal(...).
497 The method Normal(...) (used by G4VCSGfaceted::SurfaceNormal) was not
498 filling in the argument bestDistance. This fixes a bug observed in
499 G4Polyhedra::SurfaceNormal.

502 - Added diagnostics in G4Cons, G4Sphere and G4Torus in function
503 DistanceToOut(p,v,...).

505Mar 03, 00 G. Cosmo geom-solids-csg-V01-00-05
506 - Minor fixes to unit tests to make them up-to-date with recent
507 development versions (already included in tag geometry-V01-00-00a).
508 - G4PolyconeSide.cc, G4PolyhedraSide.cc: added explicit cast to G4int
509 to avoid warnings on Linux.
510
511Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04
512 - Fixed bug in DistanceToIn(p,v). Modified files: G4Trap.cc and
513 testG4Trap.cc. (V.Grichine)
514 - Syncronized file versions with HEAD (essentially CVS headers changes).
515 - Fixes for missing migration on HEAD related to some files in test/fred
516 and test/SBT.

535 - Replaced 1/DBL_MAX with DBL_MIN (valid correction, seen in tests for STL)
536 in G4PolyPhiFace.cc, G4PolyconeSide.cc and G4PolyhedraSide.cc
537
538Apr 29, 99 David Williams
539 - G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified:
540 1. Implemented correct copy constructors and assignment operators.
541 2. Fix some leaks for tracks that pass exactly through an edge.
542 Some leaks still remain: particularly if a track passes through
543 a corner and between the curved edges of G4Polycone.
544 3. G4Polyhedra argument numSide changed to G4int (from G4double)
545
546Apr 13, 99 Vladimir Grichine and Simone Giani
547 - Minor consistency fix to 8 basic CSG solids:
548 Tolerance used in calculation of extent but not in one place,
549 and not another - this tripped up the client code.
550
551Feb 16, 99 David Williams
552 - Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in
553 test/testG4Polycone and missed in below.
554 - Updated definition of DistanceToIn(p) and DistanceToOut(p) to
555 return zero when the point p is on the surface of the solid.
556
557Feb 12, 99 David Williams
558 - src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by
559 test/testG4Polycone.

561Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu)
562 - I've committed new versions of the CSG Polycone and Polyhedra in the
563 geant4 repository, including a new utility class called
564 G4ReduciblePolygon. The new versions fix several subtle bugs which my
565 "test3" batch geometry testing code uncovered. In addition, the new class
566 G4ReduciblePolygon is used to run strict tests on the validity of input
567 parameters.
568 To fix a bug in Polyhedra, I had to back out some fancy code that
569 allowed it to calculate intersections at a speed that was independent of
570 the number of sides. The new version now runs at a speed proportional to
571 the number of sides, and is thus much slower for polyhedras with many
572 sides. I can fix this, but I thought it would be best to get the bug fixes
573 in as soon as possible.
