498 Several fixes for BREPS.
499
500
501July 29th, 98 John Apostolakis (with Stefano Magni)
502
503 G4BREPSolidPCone.cc : Cylindrical sections were incorrectly placed.
504
505 G4ConicalSurface.cc
506 G4CylindricalSurface.cc:
507
508 The Inside functions are modified to try to use the Geant-4 tolerance.
509 --> must be checked further
510 [ The method is used by Intersect of respective surfaces in a
511 complicated manner. ]
512
513 G4FConicalSurface.cc
514 - Fix to Bounding Box, which was incorrectly centered/placed.
515 - Fix to Intersect, to insure that only intersection in Finite extent of
516 Surface are found.
517

521 In the Navigator location, the blocked Volume was not cleared when the
522navigator descended several levels in the tree. This would allows the same in another part of the tree to be wrongly blocked.
523
524 In G4ParameterisedNavigation, the identity of the blocked Physical Volume
525was not checked! You would block replica number 3 of your parameterised volume
526although you exited replica number 3 of another volume!
527
528 The above problems combined to allow BlockingList to be
529called with replicaNo = -1, which caused Linux/G++ & HP to dump core
530on program exit.
531
532 Modified Files:
533 G4Navigator.cc
534 G4ParameterisedNavigation.cc
535
536 An assignment used to be an equality check by mistake. (Probably it was ok
537because it is redundant)
538
539 Modified Files:
540 G4VoxelNavigation.cc

546
547June 26th, 98 John Apostolakis geometry-00-06-05
548
549 1) Modified check in ComputeStep that pseudo-relocation is within safety:
550 i) no check is made is the move is within tolerance as it makes no sense
551 - on a boundary it would cause a volume change (where there was none.)
552 ii) the Navigator now stores the last safety it calculated (origin, value)
553 and uses it for the calculation of this check.
554 This eliminates problems with this check, that produced assertion
555 failure in many example codes.
556
557 2) NavigationHistory equality operator modified for efficiency (with P.Urban)
558
559 3) G4Box Problem in DistanceToIn reporting intersection where there was
560 none has been given a more complete solution (V.Grichine)
561 G4Sphere Exception problem fixed. (V.Grichine)
562
563
564June 20th, 98 John Apostolakis geometry-00-06-04
565
566 1) I have added a check that any pseudo-relocation made between a
567 call to Locate (the true Relocation) and the next call to ComputeStep
568 (eg in a PostStepDoIt) is truly within safety.
569
570 2) The Navigator's ComputeStep method now always returns infinity, when it
571 does not limit the step
572
573 3) G4Tubs.cc: Fixed surface normal (in R) which was not a unit vector.
574
575
576June 18th, 98 John Apostolakis
577
578 In the Navigator:
579 1) Fix to allow lateral displacement (within safety) in PostStepDoIts
580 without messaging the Navigator.
581 2) A first implementation of LocateGlobalPointWithinVolume
582
583 A fix in NormalNavigation's Compute Step, to allow volumes that are "touched"
584 to be tagged as entered. (Ie, if the step is just long enough to arrive at
585 the surface of a volume, the navigator can still enter it quickly.)
586
587
588June 12th, 98 John Apostolakis (geometry-00-06-03)
589
590 Candidate fix to BREP PCone, constructing Conical Surfaces using different
591 starting point.
592
593 Fix to ReplicaNavigation to temporarily patch "assertion" problem.
594
595
596June 10th, 98 John Apostolakis (geometry-00-06-02)
597
598 Added a new CSG Solid (G4Hype), a Hyperboloid by rotation
599
600 Bug fix to G4Box::DistanceToIn (which reported intersection where there
601 was none).
602 Bug fix to G4FConicalSurface and G4ConicalSurface to fix G4BREPSolidPCone.
603 Correction to to DistanceToOut of BREPSolid to ensure compatibility with
604 convexity assumptions of Navigator
605
606
607June 8th, 98 John Apostolakis (geometry-00-06-01)
608
609 Created a tag for BREPS at the last point before merge with Peter's Developments.
610
611 Modified
612 G4Navigator and
613 G4NormalNavigation G4ParameterisedNavigation
614 G4ReplicaNavigation G4VoxelNavigation
615
616 to add ComputeSafety methods. These make a quick estimation of the
617 safety and can/should be called for the final point of a step only.
618
619
620June 3rd, 98 John Apostolakis
621
622 G4Navigator:
623
624 Added a new new method LocateGlobalPointWithinVolume that serves to notify
625 the Navigator that a track has moved to the new Global point 'position'.
626 This point must be known to be within the current volume, probably because it
627 is withing safety.
628
629May 11th, 98 John Apostolakis
630
631 G4PVPlacement:
632 - Implemented additional (4th) constructor that takes a pointer to a
633 logical mother volume and a G4Transform3D with the solid's rotation.
634 - Also added a data member to store whether a RotationMatrix was created.
635 This allows us to avoid a small memory leak in use of 2 constructors.
636
637May 8th, 98 John Apostolakis
638
639- History files created in magneticfield directory for this category.
640 It will be used exclusively for the maintenance of information in
641 this category. Only what impacts its interaction with the geometry
642 (G4PropagatorInField) will be mentioned here.
643
644- History file has existed in solids/BREPS for slightly more detailed
645 changes in that sub-category.
646
647
648April 29th, 98 John Apostolakis (geometry-00-05-05)
649
650- A significant logical error in G4VoxelNavigation::LocateNextVoxel was
651 corrected: the search for the next voxel could ignore voxels at lower levels
652
653- Small changes for DEC in GNUmakefile in BREPS & STEP
654 * Removed -cfront option from GNUmakefile for DEC. -cfront
655 overrides ANSI standard rules in cxx-6.0.
656 * Cleaned up trivial warnings on DEC (Extraneous semicolons).
657

671- Bug fixes to BREP code for Assembly level of STEP files
672 (introduced in alpha05)
673
674- Renamed file G4Point3d.hh to G4Point3d.h (because of problems
675 on Windows NT in name clash with G4Point3D.hh).
676
677
678April 22nd, 98 John Apostolakis (geom-05-02)
679- Tagged.
680
681April 21st, 98 John Apostolakis (geometry-00-05-01)
682- Added SetAllParameters methods to G4Torus and G4Para.
683- All CSG solids now inherit from the new abstract class G4CSGSolid, instead
684of directly from G4VSolid.
685- "const G4double" arguments have been changed to "G4double" for CSG methods.
686
687April 21st, 98 John Allison
688- Slightly relaxed tolerance in G4Trap (for g3tog4).
689- Corrected G4BREPSolidPolyhedra.cc for graphics_reps/G4Polyhedron.
690- Added void G4Trd::SetAllParameters.
691- Also relaxed check in G4Trd::CheckAndSetAllParameters (pdx1>=0, etc.)
692
693April 2, 98 G.Barrand
694- STEP/dirobj.cc : #ifdef WIN32, do not compile opendir and closedir.
695
696March 24, 98 G.Barrand
697- GNUmakefile : MAKESHLIB changed in G4MAKESHLIB
698
699March 13, 98 G.Cosmo (on behalf of S.Giani) - (geometry-00-04-05)
700
701- Added G4VPVParameterisation.cc including default implementations
702 of ComputeSolid() and ComputeMaterial() missing previously (J.Apostolakis).
703- Included fixes for aCC compiler in BREPS and STEP (J.Sulkimo, G.Cosmo).
704
705
706March 9, 98 J. Apostolakis - (geometry-00-04-04)
707
708- Small fix to G4BREPSolid.cc which was causing problems on HP-UX.
709 (Deleted use of floating point modulo for integers, with Jari S.)
710
711- G4Sphere: further small corrections.
712
713
714March 5, 98 J. Apostolakis - (geometry-00-04-03)
715
716- Parameterised Volume can now VARY the TYPE of SOLID and/or Material
717 by copy number. PVParameterisation classes can now compute these.
718 The Navigator has been modified to compute solid and material, and
719 to set them in the associated logical volume
720
721- Now able to process an extra level of STEP files, using new code in
722 BREPs (Jari Sulkimo).
723
724- Further cleanup of code in BREP category (Peter Urban).
725
726- Small modification in solids/STEP/GNUmakefile for Win/NT port (S. Sadilov).
727
728
729March 4, 98 J. Apostolakis - (geometry-00-04-02)
730
731- G4Sphere: corrected tests of the phi angle and with tolerance checking
732that compared squares of distances.
733
734- The World volume can now be split into replicas. This not recommended, but
735the Navigator is now able to handle it.
736
737- Cleanup of code in BREP category (Peter Urban & Jari Sulkimo)
738
739
740February 16, 98 J. Apostolakis - (geometry-00-04-01)
741
742- Replicas and parameterised physical-volumes now store the copy number of
743their current copy. (It is valid only for physical volume in the hot tree).
744Navigation routines were modified to enable this.
745
746
747February 4, 98 J. Apostolakis - (geometry-00-03-02)
748
749- A few small changes were made to the Magnetic Field classes.
750This included one that allows it to work without repeatedly
751issuing an unneccessary warning.
752
753- Small fixes to BREP and STEP parts help in fixing a problem
754with True/false on some platforms.
755
756January 28, 98 S. Sadilov
757- Small modification in GNUmakefile for Win/NT port
758
759
760January 26, 98 J. Apostolakis - (geometry-00-03-01)
761
762i) New implementation of G4NavigationHistory using G4NavigationLevel.
763This implementation allows for very fast copying of G4NavigationHistory,
764which is required in order to copy G4TouchableHistory.
765
766ii) Correction in G4ReplicaNavigation.cc in DistanceToOutPhi, influencing
767replicas divided in phi.
768
769
770December 19, 97 G. Cosmo - (alpha03)
