223May 09, 2005 V.Grichine geom-csg-V07-00-04

225 Inside(p) functions for the treatment of phi/theta surfaces.
226 They are treated now in both functions in terms of kAngTolerance.
227 The reason is that historically SurfaceNormal(p) was using only
228 kCarTolerance for estimation of shortest distance to a surface. Now,
229 following the new updated specification, the surface selection is made
230 according to Inside(p) approach (as kSurface is selected), i.e. - for
231 phi/theta surfaces in terms of kAngTolerance.
232

626
627Apr 29, 99 David Williams
628 - G4Polyhedra and G4Polycone (and G4VCSGfaceted) modified:
629 1. Implemented correct copy constructors and assignment operators.
630 2. Fix some leaks for tracks that pass exactly through an edge.
631 Some leaks still remain: particularly if a track passes through
632 a corner and between the curved edges of G4Polycone.
633 3. G4Polyhedra argument numSide changed to G4int (from G4double)
634
635Apr 13, 99 Vladimir Grichine and Simone Giani
636 - Minor consistency fix to 8 basic CSG solids:
637 Tolerance used in calculation of extent but not in one place,
638 and not another - this tripped up the client code.
639
640Feb 16, 99 David Williams
641 - Repaired bugs in G4Polycone (G4PolyconeSide.cc) as found in
642 test/testG4Polycone and missed in below.
643 - Updated definition of DistanceToIn(p) and DistanceToOut(p) to
644 return zero when the point p is on the surface of the solid.
645
646Feb 12, 99 David Williams
647 - src/G4PolyconeSide.cc updated (revision 1.4) to fix a bug discovered by
648 test/testG4Polycone.
649
650Feb 9, 99 David C. Williams (davidw@scipp.ucsc.edu)
651 - I've committed new versions of the CSG Polycone and Polyhedra in the
652 geant4 repository, including a new utility class called
653 G4ReduciblePolygon. The new versions fix several subtle bugs which my
654 "test3" batch geometry testing code uncovered. In addition, the new class
655 G4ReduciblePolygon is used to run strict tests on the validity of input
656 parameters.
657 To fix a bug in Polyhedra, I had to back out some fancy code that
658 allowed it to calculate intersections at a speed that was independent of
659 the number of sides. The new version now runs at a speed proportional to
660 the number of sides, and is thus much slower for polyhedras with many
661 sides. I can fix this, but I thought it would be best to get the bug fixes
662 in as soon as possible.
