404// Calculates the mass of a geometry tree taking into account daughters
405// up to the depth specified in the G4PhysicalVolumeModel.  Culling is
406// ignored so that all volumes are seen.
407//
408// The calculation is quite tricky, since it involves subtracting the
409// mass of that part of the mother that is occupied by each daughter and
410// then adding the mass of the daughter, and so on down the heirarchy.
411//
412// Usage for a given G4PhysicalVolumeModel* pvModel:
413//   G4PhysicalVolumeMassScene massScene;
414//   massScene.EstablishSpecials (*pvModel);
415//   pvModel->DescribeYourselfTo (massScene);
416//   G4double volume = massScene.GetVolume();
417//   G4double mass = massScene.GetMass();
418//   massScene.Reset();
419// See, for example, G4ASCIITreeSceneHandler::EndModeling().
420- Added some access functions to G4PhysicalVolumeModel:
421    GetTopPhysicalVolume, GetRequestedDepth, SetRequestedDepth.
422- Protected GetPhysicalVolumeModel when all volumes "invisible".

44022nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
441- Removed a redundant comment.
442
44320th November 2002  Gabriele Cosmo  (modeling-V04-01-00)
444- Fixed access to static data (requires "greps-V04-01-04") in
445  G4FlavoredParallelWorldModel.cc, to allow porting on Windows DLLs.
446
44711th November 2002  John Allison  (modeling-V04-00-00)
448- Added fDrawingMode data member to G4TrajectoriesModel.
449
45024th October 2002  John Allison (vis-V04-01-03)
451- Changes for AddThis(const G4VTrajectory&) and (const G4VHit&).
452
45323rd February 2002  John Allison (vis-V04-00-02)
454- Removed Begin/EndPrimitives from G4HitsModel and
455  G4TrajectoriesModel.  This was causing nested calls to
456  Begin/EndPrimitives (and thus to glNewList/EndList in OpenGL stored
457  mode), since the trajectories and hits Draw methods themselves have
458  Begin/EndPrimitives.
459
46024th August 2001  John Allison  (vis-V03-02-13)
461- Intoduced argument for printing in G4VModel::Validate(G4bool warn).
462- Changed default return value in G4VModel::Validate(G4bool) to true.
463- Invoke CalculateExtent after successful geometry change in
464  G4PhysicalVolumeModel::Validate, and other bug fixes..
465
46614th August 2001  John Allison  (vis-V03-02-11)
467- Added sceneHandler.Begin/EndPrimitives messages to models (long
468  standing bug!).
469
4709th August 2001  John Allison  (vis-V03-02-10-00)
471- Removed G4ModelingParameters::hierarchy.  It is no longer used.  The
472  textual or graphical representation of the geometry hierarchy is now
473  done in G4xxxTree classes in visua;ization/Tree.
474
47525th July 2001  John Allison  (modeling-V03-02-03)
476- Added G4VModel::GetG4PhysicalVolumeModel().
477- Added G4VModel* argument to G4BoundingSphereScene constructor.
478  Both the above are to facilitate access to a model, if it exists, and
479  to invoke methods of G4PhysicalVolumeModel if it is one.
480- Added code to curtail G4PhysicalVolumeModel search in G4BoundingSphereScene.
481
48224th July 2001  John Allison  (modeling-V03-02-02)
483- Added G4VModel::SetExtent(const G4VisExtent&).
484- Cosmetic improvements to G4BoundingSphereScene.
485- Augmented G4ScaleModel::fGlobalTag.
486
48721st July 2001  John Allison  (modeling-V03-02-01)
488- Added G4ScaleModel.
489- Fixed bug in G4BoundingSphereScene::::Accrue().
490- Also a few cosmetic changes.
491
49218th July 2001  John Allison  (modeling-V03-02-00)
493- Ensured rotation and translation of replica is restored.
494
4953rd February 2001  John Allison  (vis-V03-00-02)
496- Tidied for CodeWizard.
497
49829th May 2000  John Allison
499- Moved code for maintaining depth, physical and logical volume
500  pointers from VisitGeometryAndGetVisReps to DescribeAndDescend to
501  handle daughters of replicas correctly (Guy Barrand).
502
50322nd May 2000  John Allison  (modeling-V01-01-00)
504- Added G4VTreeGraphicsScene (DTREE).
505- Commented out pVPV->SetCopyNo(n) on Makoto's advice in
506  G4PhysicalVolumeModel.cc.
507
508vis-V01-01-01  12th April 2000  John Allison
509- Made G4PhysicalVolumeModel::DescribeSolid virtual.
510- G4PhysicalVolumeModel::DescribeSolid no longer deals with composite
511  solids - now programmed into CompositeSolid::CreatePolyhedron, where
512  CompositeSolid means G4IntersectionSolid, G4SubtractionSolid and
513  G4UnionSolid.
514- G4PhysicalVolumeModel::DescribeSolid no longer deals with displaced
515  solids - now programmed into G4DisplacedSolid::CreatePolyhedron.
516- Added G4LogicalVolumeModel::DescribeSolid, which explicitly adds
517  components of composite solids as white forced-wireframe objects.
518
519vis-V00-01-10  25th November 1999  John Allison
520- Adapted header files of modeling for Software Reference Manual.
521
522vis-01-00-05  7th February 1999  John Allison
523
524vis-01-00-05  7th February 1999  John Allison
525- Added list facility to G4PhysicalVolumeSearchScene.
526- Added virtual functions AddThis (const G4Polycone and G4Polyhedra to
527  G4BoundingSphereScene and G4PhysicalVolumeSearchScene.
528
529vis-00-04-01  25th November 1998  John Allison.
530- Added const G4VisAttributes* fpDefaultVisAttributes and access
531  functions to G4ModelingParameters.
532- Reverted to default assignment operator and copy constructor for
533  G4ModelingParameters.
534- G4PhysicalVolumeModel can now handle invisible daughters.
535
53631st August 1998  John Allison
537- Added G4VModel::Validate() and in subclasses.
538
539vis-00-02-05  27th August 1998  John Allison
540- Added G4HitsModel and G4TrajectoriesModel.
541
542vis-00-02-04  22nd August 1998  John Allison
543- Made G4Transform3D fTransform a member of G4VModel (instead of pointer).
544- Reversed order of parameters in G4VModel constructor.
545- Much bug fixing.
546
547vis-00-06-06  11th June 1998  John Allison
548- G4PhysicalVolumeModel handles parametrised solids and materials.
549
550vis-00-06-04  10th June 1998  John Allison
551- Moved G4BoundingSphereScene from management to modeling.
552- Added G4Transform3D data member.
553
554modeling-00-04-01  4th March 1998  John Allison
555- Last tag before moving to visualization.
556- Removed G4ModelingParameters:: from G4ModelingParameters.hh constructor.
557
55827th January 1998  John Allison
559- New (temporay?) category.
560- Incorporates modeling code which was in G4VScene.
