2025th February 2009 John Allison (greps-V09-02-01)
21- G4VVisManager: Added NotifyHandlers.
22 Notify scene handlers (G4VGraphicsScene objects) that the scene
23 has changed so that they may rebuild their graphics database, if
24 any, and redraw all views.
25
2624th February 2009 John Allison (greps-V09-02-00)
27- G4VMarker:
28 o Added enum SizeType {none, world, screen};

30
3113th November 2008 Gabriele Cosmo (greps-V09-01-06)

33 for memory corruption in visualization of G4Hype shape.
34

47
484th January 2008 John Allison (greps-V09-01-00 with vis-V09-01-00)

51
5221th August 2007 Tatiana Nikitina (greps-V09-00-02)
53- Fixed bug in scaling parameter for G4EllipticalCone representation in
54 HepPolyhedron class.
55

62

66
673rd April 2007 John Allison (greps-V08-02-01)
68- G4AttDefStore: now comprises utility functions in namespace
69 G4AttDefStore. (Used to be a class with only static functions and
70 data members.)
71- G4AttHolder: Made copy constructor and assignment private to enforce
72 proper usage.
73
745th January 2007 John Allison (greps-V08-02-00)

79 create and copy out the relevant colours. (Static data members make
80 a lot of noise in the gdb debugger. Anyway, are best avoided.)
81
827th November 2006 John Allison (greps-V08-01-11)
83- HepPolyhedronEllipticalCone: Bug fix.
84- G4Visible: Fixed possible minor (subsidiary) memory leak in SetVisAttributes.

98
9924th October 2006 John Allison (greps-V08-01-08; co-works: vis-V08-01-08)
100- G4VisAttributes: Change GetAttValues to CreateAttValues. It creates
101 an expendable copy on the heap, thus following the behaviour of
102 CreateAttValues in trajectories, hits, etc. This achieves consistency
103 of behaviour and user expectation; the user must delete after use.
104- G4AttHolder: Remove CopyAndAddAttValues. No longer needed after
105 above change to G4VisAttributes.
106

523- Re-engineered maintenance of current depth, etc. Needed new method
524 G4VGraphicsScene::BeginModeling (G4PhysicalVolumeModel&) in
525 graphics_reps. The result is much cleaner model and modeling
526 parameters classes. Also, the current depth, physical volume and
527 logical volume are immediately available as protected pointers in
528 G4VScene.
