172May 09, 2005 V.Grichine geom-csg-V07-00-04

174 Inside(p) functions for the treatment of phi/theta surfaces.
175 They are treated now in both functions in terms of kAngTolerance.
176 The reason is that historically SurfaceNormal(p) was using only
177 kCarTolerance for estimation of shortest distance to a surface. Now,
178 following the new updated specification, the surface selection is made
179 according to Inside(p) approach (as kSurface is selected), i.e. - for
180 phi/theta surfaces in terms of kAngTolerance.
181

416 in constructor.
417
418Nov 02, 00 G. Cosmo geom-solids-csg-V02-00-08

426 condition on check for Rmin intersection (t2 >= 0).
427
428Oct 26, 00 G. Cosmo geom-solids-csg-V02-00-06

448Oct 05, 00 V. Grichine geom-solids-csg-V02-00-03
449- G4Cons.cc:
450 o fix in DistanceToIn(p,v): corrected condition on conical surface to
451 consider a real projection of the conical surface thickness on XY
452 plane (0.5*kCarTolerance*secRMin instead of 0.5*kCarTolerance), when
453 dealing with cons with large opening angle.

508- Removed implementations of GetExtent in most sub-classes of G4VSolid (a
509 default implementation exists in G4VSolid).
510- All implementations of DescribeYourselfTo (G4VGraphicsScene& scene) const
511 now correctly written: scene.AddThis(*this).

513Apr 05, 00 G. Cosmo geom-solids-csg-V01-01-01
514 - G4Tubs.cc: fixed bug in function Inside(p).
515 Removed (commented) in the code umproper addition of 2PI
516 to Phi-angle particle (V.Grichine)
517 - G4Hype[.hh.cc]: fixed several longstanding issues and bring methods
518 into compliance with specifications (D.Williams)
519 - Moved to "specific" the following classes:
520 G4ClippablePolygon, G4EnclosingCylinder, G4Hype, G4PolyPhiFace,
521 G4Polycone, G4PolyconeSide, G4Polyhedra, G4PolyhedraSide,
522 G4ReduciblePolygon, G4IntersectingCone, G4SolidExtentList,
523 G4VCSGface, G4VCSGfaceted.
524 - Moved testG4Hype.cc and testG4Polycone.cc from CSG/test to
525 specific/test
526 - Moved generic tests "SBT" and "Fred" one level up to solids/test.
527 - Organised class description comments for the Software Reference Manual
528 in all headers.

531 - Tagged.
532
533Mar 22, 00 D. Williams
534 - G4PolyhedraSide.cc: fixed bug in G4PolyhedraSide::Normal(...).
535 The method Normal(...) (used by G4VCSGfaceted::SurfaceNormal) was not
536 filling in the argument bestDistance. This fixes a bug observed in
537 G4Polyhedra::SurfaceNormal.
538
539Mar 14, 00 V. Grichine
540 - Added diagnostics in G4Cons, G4Sphere and G4Torus in function

544 - Minor fixes to unit tests to make them up-to-date with recent
545 development versions (already included in tag geometry-V01-00-00a).
546 - G4PolyconeSide.cc, G4PolyhedraSide.cc: added explicit cast to G4int
547 to avoid warnings on Linux.
548
549Jan 19, 00 G. Cosmo geom-solids-csg-01-00-04
550 - Fixed bug in DistanceToIn(p,v). Modified files: G4Trap.cc and

572May 18, 99 David Williams
573 - Replaced 1/DBL_MAX with DBL_MIN (valid correction, seen in tests for STL)
574 in G4PolyPhiFace.cc, G4PolyconeSide.cc and G4PolyhedraSide.cc
575
576Apr 29, 99 David Williams
577 - G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified:
578 1. Implemented correct copy constructors and assignment operators.
579 2. Fix some leaks for tracks that pass exactly through an edge.
580 Some leaks still remain: particularly if a track passes through
581 a corner and between the curved edges of G4Polycone.
582 3. G4Polyhedra argument numSide changed to G4int (from G4double)
583
584Apr 13, 99 Vladimir Grichine and Simone Giani
585 - Minor consistency fix to 8 basic CSG solids:
586 Tolerance used in calculation of extent but not in one place,
587 and not another - this tripped up the client code.
588
589Feb 16, 99 David Williams
590 - Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in
591 test/testG4Polycone and missed in below.
592 - Updated definition of DistanceToIn(p) and DistanceToOut(p) to
593 return zero when the point p is on the surface of the solid.
594
595Feb 12, 99 David Williams
596 - src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by
597 test/testG4Polycone.
598
599Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu)
600 - I've committed new versions of the CSG Polycone and Polyhedra in the
601 geant4 repository, including a new utility class called
602 G4ReduciblePolygon. The new versions fix several subtle bugs which my
603 "test3" batch geometry testing code uncovered. In addition, the new class
604 G4ReduciblePolygon is used to run strict tests on the validity of input
605 parameters.
606 To fix a bug in Polyhedra, I had to back out some fancy code that
607 allowed it to calculate intersections at a speed that was independent of
608 the number of sides. The new version now runs at a speed proportional to
609 the number of sides, and is thus much slower for polyhedras with many
610 sides. I can fix this, but I thought it would be best to get the bug fixes
611 in as soon as possible.
