147- Updated unit test testSurfaceNormal.cc.
148
149May 09, 2005 V.Grichine geom-csg-V07-00-04

151 Inside(p) functions for the treatment of phi/theta surfaces.
152 They are treated now in both functions in terms of kAngTolerance.
153 The reason is that historically SurfaceNormal(p) was using only
154 kCarTolerance for estimation of shortest distance to a surface. Now,
155 following the new updated specification, the surface selection is made
156 according to Inside(p) approach (as kSurface is selected), i.e. - for
157 phi/theta surfaces in terms of kAngTolerance.
158

425Oct 05, 00 V. Grichine geom-solids-csg-V02-00-03
426- G4Cons.cc:
427 o fix in DistanceToIn(p,v): corrected condition on conical surface to
428 consider a real projection of the conical surface thickness on XY
429 plane (0.5*kCarTolerance*secRMin instead of 0.5*kCarTolerance), when
430 dealing with cons with large opening angle.
431 o Updated unit test testG4Cons2.cc.

435 o fix in constructor to check if one of the Rmin is equal to 0,
436 if so, it will be set to 1e3*kRadTolerance.
437 o Deactivated call to G4Exception in DistanceToOut(p) if p is outside,
438 replaced by simple warning.
439- G4Tubes.cc, G4Box.cc:
440 o Deactivated call to G4Exception in DistanceToOut(p) if p is outside,
441 replaced by simple warning.

469- G4Tubs.cc:
470 o introduced fix in DistanceToOut(p,v,...) in computation of xi, yi for

485- Removed implementations of GetExtent in most sub-classes of G4VSolid (a
486 default implementation exists in G4VSolid).
487- All implementations of DescribeYourselfTo (G4VGraphicsScene& scene) const
488 now correctly written: scene.AddThis(*this).

490Apr 05, 00 G. Cosmo geom-solids-csg-V01-01-01
491 - G4Tubs.cc: fixed bug in function Inside(p).
492 Removed (commented) in the code umproper addition of 2PI
493 to Phi-angle particle (V.Grichine)
494 - G4Hype[.hh.cc]: fixed several longstanding issues and bring methods
495 into compliance with specifications (D.Williams)
496 - Moved to "specific" the following classes:
497 G4ClippablePolygon, G4EnclosingCylinder, G4Hype, G4PolyPhiFace,
498 G4Polycone, G4PolyconeSide, G4Polyhedra, G4PolyhedraSide,
499 G4ReduciblePolygon, G4IntersectingCone, G4SolidExtentList,
500 G4VCSGface, G4VCSGfaceted.
501 - Moved testG4Hype.cc and testG4Polycone.cc from CSG/test to
502 specific/test
503 - Moved generic tests "SBT" and "Fred" one level up to solids/test.
504 - Organised class description comments for the Software Reference Manual
505 in all headers.

510Mar 22, 00 D. Williams
511 - G4PolyhedraSide.cc: fixed bug in G4PolyhedraSide::Normal(...).
512 The method Normal(...) (used by G4VCSGfaceted::SurfaceNormal) was not
513 filling in the argument bestDistance. This fixes a bug observed in
514 G4Polyhedra::SurfaceNormal.
515
516Mar 14, 00 V. Grichine
517 - Added diagnostics in G4Cons, G4Sphere and G4Torus in function

521 - Minor fixes to unit tests to make them up-to-date with recent
522 development versions (already included in tag geometry-V01-00-00a).
523 - G4PolyconeSide.cc, G4PolyhedraSide.cc: added explicit cast to G4int
524 to avoid warnings on Linux.
525
526Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04
527 - Fixed bug in DistanceToIn(p,v). Modified files: G4Trap.cc and
528 testG4Trap.cc. (V.Grichine)
529 - Syncronized file versions with HEAD (essentially CVS headers changes).
530 - Fixes for missing migration on HEAD related to some files in test/fred
531 and test/SBT.

550 - Replaced 1/DBL_MAX with DBL_MIN (valid correction, seen in tests for STL)
551 in G4PolyPhiFace.cc, G4PolyconeSide.cc and G4PolyhedraSide.cc
552
553Apr 29, 99 David Williams
554 - G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified:
555 1. Implemented correct copy constructors and assignment operators.
556 2. Fix some leaks for tracks that pass exactly through an edge.
557 Some leaks still remain: particularly if a track passes through
558 a corner and between the curved edges of G4Polycone.
559 3. G4Polyhedra argument numSide changed to G4int (from G4double)
560
561Apr 13, 99 Vladimir Grichine and Simone Giani
562 - Minor consistency fix to 8 basic CSG solids:
563 Tolerance used in calculation of extent but not in one place,
564 and not another - this tripped up the client code.
565
566Feb 16, 99 David Williams
567 - Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in
568 test/testG4Polycone and missed in below.
569 - Updated definition of DistanceToIn(p) and DistanceToOut(p) to
570 return zero when the point p is on the surface of the solid.
571
572Feb 12, 99 David Williams
573 - src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by
574 test/testG4Polycone.
575
576Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu)
577 - I've committed new versions of the CSG Polycone and Polyhedra in the
578 geant4 repository, including a new utility class called
579 G4ReduciblePolygon. The new versions fix several subtle bugs which my
580 "test3" batch geometry testing code uncovered. In addition, the new class
581 G4ReduciblePolygon is used to run strict tests on the validity of input
582 parameters.
583 To fix a bug in Polyhedra, I had to back out some fancy code that
584 allowed it to calculate intersections at a speed that was independent of
585 the number of sides. The new version now runs at a speed proportional to
586 the number of sides, and is thus much slower for polyhedras with many
587 sides. I can fix this, but I thought it would be best to get the bug fixes
588 in as soon as possible.
