21- G4OpenGLImmediate/StoredQtViewer : Fix compilation warnings
22- G4OpenGLQtViewer : Add protection on Vis Tab without UI Qt
23
244th June 2010  Laurent Garnier (opengl-V09-03-07)
25- G4OpenGLImmediate/StoredQtViewer : Add protection against multiple
26  repaint call. Add protection against resizeGl with bad values
27
283rd June 2010  John Allison  (opengl-V09-03-06)
29- G4OpenGLImmediateSceneHandler: Re-instate
30  // Make sure screen corresponds to graphical database...
31  if (fpViewer) {
32    fpViewer -> SetView ();
33    fpViewer -> ClearView ();
34    fpViewer -> DrawView ();
35  }
36  I was wrong - it *is* necessary.  If not there, events are not refreshed.
37  So this and similar changes below are all back to geant4-09-03, including
38  glFlush, which is still a big performance penalty on Mac's Snow Leopard.
39
403rd June 2010  John Allison  (opengl-V09-03-05)
41- Restored following files to geant4-09-03 in interests of stable behaviour:
42  o G4OpenGLStoredSceneHandler.cc
43    Restored code removed in opengl-V09-03-03:
44  // Make sure screen corresponds to graphical database...
45  if (fpViewer) {
46    fpViewer -> SetView ();
47    fpViewer -> ClearView ();
48    fpViewer -> DrawView ();
49  }
50  o G4OpenGLStoredXViewer.cc:
51    Restore to geant4-09-03.  Restored code removed in opengl-V09-03-03:
52      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
53        DrawDisplayLists ();
54        FinishView ();
55- Note: G4OpenGLImmediateSceneHandler: Same code commented out.  I think
56  it's not necessary for immediate mode.
57
5830th May 2010  John Allison  (opengl-V09-03-04)
59- G4OpenGLSceneHandler: Added AddCompound(const G4VDigi&).
60
6129th May 2010  John Allison  (opengl-V09-03-03)
62- G4OpenGLImmediateSceneHandler.cc, G4OpenGLStoredSceneHandler.cc:
63  Removed the following from ClearTransientStrore (was causing
64  unnecessary drawing and flipping buffers?):
65  // Make sure screen corresponds to graphical database...
66  if (fpViewer) {
67    fpViewer -> SetView ();
68    fpViewer -> ClearView ();
69    fpViewer -> DrawView ();
70  }
71- G4OpenGLStoredXViewer.cc:
72  Commented out as follows in DrawView (was causing extra buffer swap,
73  thus showing bad picture; can't recall why it was introduced):
74      } else { // ADD TO AVOID KernelVisit=1 and nothing to display
75        //DrawDisplayLists ();  ????????? (JA)
76        //FinishView ();        ????????? (JA)

453  for OGL*Win32.  Still doesn't work for OGL*Xm.
454
4553rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
456- G4OpenGLStoredSceneHandler:
457  o Re-organised display lists on a per-primitive basis, i.e., one
458    display list per primitive.  (This is so that, except for text,
459    the colour - or, rather, intensity - can be brought out of the
460    display list into the TOList (Transient Object List) and
461    controlled for the Display-by-Time feature.  Previously, if more
462    than one primitive were drawn between BeginPrimitives and
463    EndPrimitives, it would finish up all in one display list, colour
464    commands included. Rationalises and fixes a rare bug in the
465    Display-by-Time feature - see August 2006.)
466  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
467    one primoitive to fit with the above re-organisation.
468- Implemented picking for OGLIX.
469
47025th March 2007  John Allison  (opengl-V08-02-03)
471- Fix compiler warnings.
472
4738th February 2007  John Allison  (opengl-V08-02-02)
474- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
475- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
476  .but not switched back.  Not serious, because context was always set
477  before normal drawing.)
478
4799th January 2007  John Allison  (opengl-V08-02-01)
480- Implemented bitmap markers for MarkerSizeType == screen.  (The old
481  polygon implementation remains for MarkerSizeType == world.)
482- Added G4OpenGLBitMapStore to assist the above.
483- G4OpenGLXViewer::CreateGLXContext:
484  o Bug fix: Added missing break in colormap lookup routine.
485
4865th January 2007  John Allison  (opengl-V08-02-00)
487- G4OpenGLSceneHandler.cc:
488  o Followed change of signature of GetLineWidth in visman-V08-02-00.
489  o Minor efficiency improvements.
490
49121st November 2006  John Allison  (opengl-V08-01-09)
492- Fixed compiler warnings.
493
4941st November 2006  John Allison  (opengl-V08-01-08)
495- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
496  actually initiates a print, rather than set a flag for printing.
497
49824th October 2006  John Allison  (opengl-V08-01-07)
499- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
500- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
501
50219th September 2006  John Allison  (opengl-V08-01-06)
503- Added time origin for light front.
504- Added /vis/ogl/set/transparency.
505- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
506
5074th September 2006  John Allison  (opengl-V08-01-05)
508- Implement cutaways.
509- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
510  primitives (see detector being drawn).
511- /vis/oglx/set/printEPS: change parameter default to true.
512
51330th August 2006  John Allison  (opengl-V08-01-04)
514- G4OpenGLSceneHandler:
515  o Implemented line width.
516  o Switched off back face culling when clipping so that the inside of
517    volumes can be seen.
518  o Added CreateSection/CutawayPolyhedron to exploit generic
519    sectioning (DCUT) and cutaways.  Currently not activated due to
520    instabilities in BooleanProcessor.  Local sectioning still active
521    but broken (at least on Mac) due to apparent change in effect of
522    clipping planes (polyhedron edges not reconstructed).
523  o Rationalised calculation of marker size.
524- G4OpenGLStoredSceneHandler:
525  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
526  o Pick up time range from G4VisAttributes.
527- G4OpenGLViewer(Messenger):
528  o Added position and colour to /vis/ogl/set/displayHeadTime.
529  o Added /vis/ogl/set/displayLightFront.
530- G4OpenGLStoredViewer.cc:
531  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
532  o Added position and colour to DisplayHeadTime.
533  o Added DisplayLightFront.
534 
53516th August 2006  John Allison  (opengl-V08-01-03)
536- Corrected Solaris compilation error.
537- Added /vis/ogl/set/fade and displayHeadTime.
538
53914th August 2006  John Allison  (opengl-V08-01-02)
540- Needs visman-V08-01-02.
541- G4OpenGLStored: Implemented display-by-time.  Only available in
542  stored mode at present.  Only implemented for circle, square,
543  polyline and polymarker at present, enough for currently available
544  trajectory models.  Time is communicated via G4AttValues.
545- Added G4OpenGLViewerMessenger.
546- Added /vis/ogl/set/startTime and endTime of displayed objects.
547- All factories: Instantiated G4OpenGLViewerMessenger.
548- G4OpenGLViewer: Added fStart/EndTime.
549- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
550  spewPrimitiveEPS and spewSortedFeedback.
551
55217th July  John Allison  (opengl-V08-01-01)
553- Added /vis/oglx/set/printEPS (prints eps file on every update).
554
5553rd July 2006  John Allison  (opengl-V08-01-00)
556- Elimination of redundant variable doublebuffer and implementation of
557  FinishView in all viewers.
558
55930th May 2006  Joseph Perl  (opengl-V08-00-08)
560- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
561  variable seems to have random behavior and should be assumed false for
562  this viewer.
563
56429th May 2006  Joseph Perl  (opengl-V08-00-07)
565- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
566  Removed common FinishView and instead made separate FinishView for the two different
567  versions of this viewer since each wants a different buffer swapping behaviour.
568
56912th May 2006  John Allison  (opengl-V08-00-06)
570- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
571
57228th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
573- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
574  recomputing transients.
575
57624th April 2006  John Allison  (opengl-V08-00-04)
577- Fixed compilation problem on Windows.
578
57919th April 2006  John Allison  (opengl-V08-00-03)
580- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
581  G4OpenGLImmediateSceneHandler:
582  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
583    greps-V08-00-02).
584  o Migrated to direct access to G4PhysicalVolumeModel.
585- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
586  of display lists in DrawView.
587
58814th March 2006  John Allison  (opengl-V08-00-02)
589- Refined display list building and re-drawing algorithm.
590  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
591  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
592- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
593  re-use algorithm.  In test19 with global culling off, numbers of
594  display lists used are:
595  o 191  No re-use:
596  o  73  Before this change: re-use except replicas (includes parameterised).
597  o  33  After this change: re-use except parameterised and replicas in radius.
598
59926th January 2006  John Allison  (opengl-V08-00-01)
600- Coworks with visman-V08-00-04 (removed fModified).
601- Removed references to fModified.
602- Tidying: Removed unnecessary ClearView.
603- G4OpenGLSceneHandler.cc: Added some (commented out) code for
604  possible future implementation of 2D drawing.
605- G4OpenGLXViewer.cc: Improved exception printing.
606
60711th January 2006  John Allison  (opengl-V08-00-00)
608- Improved efficiency: all DrawView's:
609  o Don't call ClearView.
610  o Set flag so SetView will not be called in ProcessView.
611  o Leave background colour to ClearView.
612- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
613- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
614  for current viewer.
615
61624th November 2005  John Allison  (opengl-V07-01-09)
617- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
618
61922nd November 2005  John Allison  (opengl-V07-01-08)
620- Added G4OpenGLXmViewerMessenger.
621- Corrected text position.
622- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
623
62417th November 2005  Gabriele Cosmo
625- Fixed settings of background style for WIN32 viewers.
626
62713th November 2005  John Allison  (opengl-V07-01-07)
628- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
629
63013th October 2005  John Allison  (opengl-V07-01-06)
631- Allowed any colour background.
632- Implemented non-uniform scaling.
633- Migration to <sstream>.
634
63529th September 2005  John Allison  (opengl-V07-01-05)
636- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
637  scene handler.
638- Re-implemented transparency button in OpenGLXm.
639
64013th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
641- Implemented white background for all OGL viewers.
642- G4OpenGLSceneHandler.cc:
643  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
644  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
645  o Corrected GetTextColour(text).
646  o Corrected GetColour(polyhedron).
647
6485th September 2005  John Allison  (opengl-V07-01-03)
649- Bug fix: stored transparent objects were being lost.
650
6512nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
652- Bug fix: edgeflags problem introduced with smooth shading in
653  opengl-V07-01-00.
654- Implementation of a "better algorithm" for the rendering of
655  transparent polyhedron objects.  It renders all opaque objects
656  first, then renders the transparent objects with the depth buffer in
657  read-only mode (see OpenGL Programming Guide).  It uses the new
658  facility in G4VSceneHandler::ProcessScene for an optional second pass
659  of the run-duration models in the scene.  Note this algorithm is
660  still only an approximation.  It will still give the wrong blended
661  colour if two transparent objects are rendered front first.  For
662  nested transparent objects, this is unfortunate, because
663  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
664  in such a way that mothers come first.  Also, there is no guaranteed
665  relationship between the order of rendering and the depth of two
666  transparent objects if they are at the same level or in different
667  branches of the hierarchy.  Still, the only error will be an
668  incorrect colour - the objects will still give the appearance of
669  transparency, so it's a pretty good algorithm.  (An even better
670  algorithm would be to attempt to render the facets in depth order,
671  deepest first.  But how do you calculate the depth - centre of area,
672  deepest corner?  One can still imagine pathalogical cases that would
673  sometimes give the wrong colour.  Also, for stored mode, the order
674  is fixed in a display list so when the user rotates the view, one
675  would lose the depth ordering.  I think we have to accept that
676  blending in OpenGL is only ever an approximation.  For accurate
677  blending, use RayTracer.)
678
67928th August 2005  John Allison  (opengl-V07-01-01)
680- Half-way implementation of rendering of transparent polyhedron
681  objects.  In this implementation, no account is taken of the order
682  of rendering.  Transparent objects are rendered with depth testing
683  off so that objects behind can still be seen.  But this means that
684  opaque objects in front do not obscure them - and they jolly well
685  should!  A better algorithm is to render all opaque objects first,
686  then render the transparent objects with the depth buffer in
687  read-only mode (see OpenGL Programming Guide).  This is going to
688  take a little more thought - see opengl-V07-01-02.
689
69020th July 2005  John Allison  (opengl-V07-01-00)
691- Introduced smooth shading, taking advantage of hitherto un-noticed
692  feature of HepPolyhedron::GetNextFacet that calculates the normals
693  at each vertex so that curved surfaces are rendered more
694  realistically (Gouraud shading).
695- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
696- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
697  the default window size.  It used to be 400x400, hardcoded in
698  G4OpenGLXmViewer.cc, but now it picks up the
699  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
700  The user may change it on the command line, e.g:
701    /vis/open OGLSXm 500
702  or
703    /vis/viewer/create ! ! 500
704
70530th May 2005  John Allison  (opengl-V07-00-03)
706- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
707  map of vectors in G4OpenGLFontBaseStore.)
708
7094th May 2005  John Allison  (opengl-V07-00-02)
710- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
711  was taken out to prevent recursive calling, but that seems to be OK,
712  and it is needed to implement refresh at end of event/run.)
713
71422nd April 2005  John Allison  (opengl-V07-00-01)
715- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
716  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
717  o In all concrete viewers, added call to CreateFontLists().
718  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
719  o There is no longer a need to implement in the XmViewer, since it
720    now inherits.  Thus the font code now only appears once for X.
721  o Awaiting implementation for WIN32.
722
72317th April 2005  John Allison  (opengl-V07-00-00)
724- Based on vis-V07-00-13.
725- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
726  creates display lists for nominated fonts.  Simple-minded scheme in
727  which each viewer creates its own font display lists for a variety
728  of sizes, which are accessed by the scene handler through a new
729  class, G4OpenGLFontBaseStore.  Affected methods:
730    G4OpenGLXViewer::CreateMainWindow()
731    G4OpenGLXmViewer::CreateMainWindow()
732    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
733
73418th November 2004  John Allison  (opengl-V06-02-07)
735- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
736
73715th November 2004  Guy Barrand
738- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
739  to see trajectories (for example with N03). Correct so that
740  ShowView do a FinishView that does : glFlush, wglSwapBuffer
741  and empty the Windows message queue.
742
74322nd September 2004  John Allison  (opengl-V06-02-06)
744- doxygen output to tmp area.
745- Trap non-regular polyhedrons.
746
74713th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
748- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
749  to allow for porting on CLHEP-1.9.X series.
750
75123rd July 2004  John Allison
752- Draws auxiliary edges if required.
753- Added auxiliary edge button.
754
75516th July 2004  John Allison  (opengl-V06-02-04)
756- Refinements to hidden line, hidden surface removal.
757
75814th July 2004  John Allison  (opengl-V06-02-03)
759- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
760
76113th July 2004  John Allison  (opengl-V06-02-02)
762- Hidden line *and* hidden surface removal now works.
763
7649th July 2004  John Allison  (opengl-V06-02-01)
765- Fixed long-standing problem with hidden line removal.
766- Improved messages on failure to get visual.
767- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
768  systems provided by default anyway, so no effect.
769
7701st July 2004  John Allison  (opengl-V06-02-00)
771- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
772- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
773
77418th June 2004  Gunter Folger (geant4-06-02)
7759th June 2004  Gabriele Cosmo  (vis-V06-01-03)
7767th June 2004  Gabriele Cosmo  (vis-V06-01-02)
777- GNUmakefile and disclaimer changes - see visualization/History.
778
7799th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
780- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
781
7827th April 2004  Guy Barrand
783- visualization/OpenGL/* : use the G4OpenGL.hh file.
784- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
785  the include of gl/gl.h and gl/glu.h that may be platform dependant.
786  It permits to rm some #ifdef WIN32 spread in the code. It opens also
787  the way to the usage of the Apple OpenGL on a Mac.
788
78917th February 2004  John Allison  (opengl-V06-00-00)
790- Fixed bug #581: wrong order of statements in
791  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
792
7934th October 2003  Gabriele Cosmo  (vis-V05-02-01)
794- GNUmakefile:
795  o replaced "digits+hits" with "digits_hits".
796- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
797
79822nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
799- Cosmetic change to regularise names:
800  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
801  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
802
80323rd June 2003  Guy Barrand  (opengl-V05-01-02)
804- Commit a first implementation of G4OpenGLWin32Viewer.
805
80610th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
807- More fixes for warnings in viewers classes.
808- Added inclusion of <windows.h> for WIN32 platforms when GL headers
809  are included.
810
81105th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
812- Fixes for porting compilation on WIN32:
813  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
814  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
815    since declared 'obsolete' in WIN32 platforms.
816
81727th November 2002  John Allison  (vis-V04-01-08)
818- Improved algorithm of CompareForKernelVisit.
819
82011th November 2002  John Allison  (opengl-V04-01-02)
821- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
822- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
823  call default but there as a marker and encourager.
824- Added tracking and digits+hits/hits to GNUmakefile.
825
82616th October 2002  John Allison  (opengl-V04-01-01)
827- Fix for WIN32.  Now compiles but viewer not implemented.
828
82924th June 2002  John Allison  (opengl-V04-01-00)
830- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
831
83210th June 2002  John Allison  (opengl-V04-00-03)
833- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
834
8356th June 2002  John Allison  (opengl-V04-00-02)
836- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
837
83823rd February 2002  John Allison  (opengl-V04-00-01)
839- Changes to encourage compilation on Windows in preparation for
840  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
841  glx.h, unistd.h and assert.h.
842
84324th August 2001  John Allison  (vis-V03-02-13)
844- Limited the printing of warnings in
845  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
846
84714th August 2001  John Allison  (vis-V03-02-11)
848- Improved KernelVisitDecision.
849- Fixed a few small bugs in multiple "stored" viewers, but see next item.
850- There's an outstanding bug in OpenGL Stored.  If there is more than
851  one viewer controlled by a scene handler, after a ClearStore on the
852  scene handler, e.g., with /vis/scene/notifyHandlers, the first
853  viewer to get refreshed should trigger the display list rebuild, but
854  the second need not.  However, when the second viewer's turn comes,
855  the display lists are there, and are called, e.g.,
856  G4OpenGLStoredXViewer::DrawView calls
857  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
858  nothing appears on the screen.  To overcome this there is some
859  temporary code in G4VViewer::NeedKernelVisit which marks *all*
860  viewers to force a rebuild.  To see the symptoms, comment out that
861  temporary code and issue these commands:
862    /vis/verbose c
863    /control/verbose 2
864    /vis/scene/create
865    /vis/scene/add/volume

884  One of the viewers is empty.  Curious!!

8869th August 2001  John Allison  (vis-V03-02-10-00)
887- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
888- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
889  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
890  picked up by inheritance anyway.
891- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
892- Corrected order of calling base class functions in
893  G4OpenGLStoredSceneHandler::Begin/EndModeling.
894
89524th July 2001  John Allison  (vis-V03-02-06)
896- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
897
89814th July 2001  John Allison (opengl-V03-02-00)
899- Fixed crash in optimised mode: added Initialise() to viewers so
900  that windows are opened after viewers are fully constructed.
901
9022nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
903- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
904
9057th March 2001  John Allison
906- Changed char* to const char* in many places and that gave problems in
907  calls to Xt and Xm.  Hope all's OK.  Differences:

91025th January 2001  John Allison  (opengl-V03-00-00)
911- Implemented running re-calculation of up-vector in the case of "object
912  rotation" (lights move with camera) to prevent "flipping" of view when
913  camera passes through up-vector.  Note that the default is "camera
914  rotation" (lights do not move with camera, i.e., remain fixed relative
915  to object) so the default is that this "flipping" can happen.  To set
916  "object rotation" (lights move with camera) use
917  /vis/lights/move_with_camera true (soon to be
918  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
919  on Rotation Panel in OpenGLXm mode.
920- Changed some objects to references for efficiency.  E.g.:
921  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
922
92322nd May 2000  John Allison  (opengl-V01-01-00)
924- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
925  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
926    static XVisualInfo* vi_single_buffer;
927    static XVisualInfo* vi_double_buffer;
928- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
929  G4OpenGLXViewer.
930- Protected double deletion of window in destructors of G4OpenGLXmViewer
931  and G4OpenGLXViewer (Guy Barrand).
932- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
933- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
934  constructors.
