72
733rd June 2010 John Allison (opengl-V09-03-06)
74- G4OpenGLImmediateSceneHandler: Re-instate
75 // Make sure screen corresponds to graphical database...
76 if (fpViewer) {
77 fpViewer -> SetView ();
78 fpViewer -> ClearView ();
79 fpViewer -> DrawView ();
80 }
81 I was wrong - it *is* necessary. If not there, events are not refreshed.
82 So this and similar changes below are all back to geant4-09-03, including
83 glFlush, which is still a big performance penalty on Mac's Snow Leopard.
84
853rd June 2010 John Allison (opengl-V09-03-05)
86- Restored following files to geant4-09-03 in interests of stable behaviour:
87 o G4OpenGLStoredSceneHandler.cc
88 Restored code removed in opengl-V09-03-03:
89 // Make sure screen corresponds to graphical database...
90 if (fpViewer) {
91 fpViewer -> SetView ();
92 fpViewer -> ClearView ();
93 fpViewer -> DrawView ();
94 }
95 o G4OpenGLStoredXViewer.cc:
96 Restore to geant4-09-03. Restored code removed in opengl-V09-03-03:
97 } else { // ADD TO AVOID KernelVisit=1 and nothing to display
98 DrawDisplayLists ();
99 FinishView ();
100- Note: G4OpenGLImmediateSceneHandler: Same code commented out. I think
101 it's not necessary for immediate mode.
102
10330th May 2010 John Allison (opengl-V09-03-04)
104- G4OpenGLSceneHandler: Added AddCompound(const G4VDigi&).

107- G4OpenGLImmediateSceneHandler.cc, G4OpenGLStoredSceneHandler.cc:
108 Removed the following from ClearTransientStrore (was causing
109 unnecessary drawing and flipping buffers?):
110 // Make sure screen corresponds to graphical database...
111 if (fpViewer) {
112 fpViewer -> SetView ();
113 fpViewer -> ClearView ();
114 fpViewer -> DrawView ();
115 }
116- G4OpenGLStoredXViewer.cc:
117 Commented out as follows in DrawView (was causing extra buffer swap,
118 thus showing bad picture; can't recall why it was introduced):
119 } else { // ADD TO AVOID KernelVisit=1 and nothing to display
120 //DrawDisplayLists (); ????????? (JA)
121 //FinishView (); ????????? (JA)

48316th May 2007 John Allison (opengl-V08-03-00)
484- Fix compiler warnings on SLC4.
485- Bug fixes:
486 o Correct path /vis/ogl/set/printMode.
487 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
488 and "/vis/ogl/printEPS").
489
4908th May 2007 John Allison (opengl-V08-02-06)
491- Moved vectored PostScript printing to G4OpenGLViewer.
492- /vis/ogl/printEPS should work for all viewers, including Win32.
493- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
494 effective on X windows (and still somewhat buggy).
495
4964th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
497- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
498 for OGL*Win32. Still doesn't work for OGL*Xm.
499
5003rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
501- G4OpenGLStoredSceneHandler:
502 o Re-organised display lists on a per-primitive basis, i.e., one
503 display list per primitive. (This is so that, except for text,
504 the colour - or, rather, intensity - can be brought out of the
505 display list into the TOList (Transient Object List) and
506 controlled for the Display-by-Time feature. Previously, if more
507 than one primitive were drawn between BeginPrimitives and
508 EndPrimitives, it would finish up all in one display list, colour
509 commands included. Rationalises and fixes a rare bug in the
510 Display-by-Time feature - see August 2006.)
511 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
512 one primoitive to fit with the above re-organisation.
513- Implemented picking for OGLIX.
514
51525th March 2007 John Allison (opengl-V08-02-03)
516- Fix compiler warnings.
517
5188th February 2007 John Allison (opengl-V08-02-02)
519- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
520- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
521 .but not switched back. Not serious, because context was always set
522 before normal drawing.)
523
5249th January 2007 John Allison (opengl-V08-02-01)
525- Implemented bitmap markers for MarkerSizeType == screen. (The old
526 polygon implementation remains for MarkerSizeType == world.)
527- Added G4OpenGLBitMapStore to assist the above.
528- G4OpenGLXViewer::CreateGLXContext:
529 o Bug fix: Added missing break in colormap lookup routine.
530
5315th January 2007 John Allison (opengl-V08-02-00)
532- G4OpenGLSceneHandler.cc:
533 o Followed change of signature of GetLineWidth in visman-V08-02-00.
534 o Minor efficiency improvements.
535
53621st November 2006 John Allison (opengl-V08-01-09)
537- Fixed compiler warnings.
538
5391st November 2006 John Allison (opengl-V08-01-08)
540- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
541 actually initiates a print, rather than set a flag for printing.
542
54324th October 2006 John Allison (opengl-V08-01-07)
544- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
545- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
546
54719th September 2006 John Allison (opengl-V08-01-06)
548- Added time origin for light front.
549- Added /vis/ogl/set/transparency.
550- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
551
5524th September 2006 John Allison (opengl-V08-01-05)
553- Implement cutaways.
554- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
555 primitives (see detector being drawn).
556- /vis/oglx/set/printEPS: change parameter default to true.
557
55830th August 2006 John Allison (opengl-V08-01-04)
559- G4OpenGLSceneHandler:
560 o Implemented line width.
561 o Switched off back face culling when clipping so that the inside of
562 volumes can be seen.
563 o Added CreateSection/CutawayPolyhedron to exploit generic
564 sectioning (DCUT) and cutaways. Currently not activated due to
565 instabilities in BooleanProcessor. Local sectioning still active
566 but broken (at least on Mac) due to apparent change in effect of
567 clipping planes (polyhedron edges not reconstructed).
568 o Rationalised calculation of marker size.
569- G4OpenGLStoredSceneHandler:
570 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
571 o Pick up time range from G4VisAttributes.
572- G4OpenGLViewer(Messenger):
573 o Added position and colour to /vis/ogl/set/displayHeadTime.
574 o Added /vis/ogl/set/displayLightFront.
575- G4OpenGLStoredViewer.cc:
576 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
577 o Added position and colour to DisplayHeadTime.
578 o Added DisplayLightFront.
579
58016th August 2006 John Allison (opengl-V08-01-03)
581- Corrected Solaris compilation error.
582- Added /vis/ogl/set/fade and displayHeadTime.
583
58414th August 2006 John Allison (opengl-V08-01-02)
585- Needs visman-V08-01-02.
586- G4OpenGLStored: Implemented display-by-time. Only available in
587 stored mode at present. Only implemented for circle, square,
588 polyline and polymarker at present, enough for currently available
589 trajectory models. Time is communicated via G4AttValues.
590- Added G4OpenGLViewerMessenger.
591- Added /vis/ogl/set/startTime and endTime of displayed objects.
592- All factories: Instantiated G4OpenGLViewerMessenger.
593- G4OpenGLViewer: Added fStart/EndTime.
594- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
595 spewPrimitiveEPS and spewSortedFeedback.
596
59717th July John Allison (opengl-V08-01-01)
598- Added /vis/oglx/set/printEPS (prints eps file on every update).
599
6003rd July 2006 John Allison (opengl-V08-01-00)
601- Elimination of redundant variable doublebuffer and implementation of
602 FinishView in all viewers.
603
60430th May 2006 Joseph Perl (opengl-V08-00-08)
605- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
606 variable seems to have random behavior and should be assumed false for
607 this viewer.
608
60929th May 2006 Joseph Perl (opengl-V08-00-07)
610- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
611 Removed common FinishView and instead made separate FinishView for the two different
612 versions of this viewer since each wants a different buffer swapping behaviour.
613
61412th May 2006 John Allison (opengl-V08-00-06)
615- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
616
61728th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
618- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
619 recomputing transients.
620
62124th April 2006 John Allison (opengl-V08-00-04)
622- Fixed compilation problem on Windows.
623
62419th April 2006 John Allison (opengl-V08-00-03)
625- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
626 G4OpenGLImmediateSceneHandler:
627 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
628 greps-V08-00-02).
629 o Migrated to direct access to G4PhysicalVolumeModel.
630- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
631 of display lists in DrawView.
632
63314th March 2006 John Allison (opengl-V08-00-02)
634- Refined display list building and re-drawing algorithm.
635 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
636 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
637- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
638 re-use algorithm. In test19 with global culling off, numbers of
639 display lists used are:
640 o 191 No re-use:
641 o 73 Before this change: re-use except replicas (includes parameterised).
642 o 33 After this change: re-use except parameterised and replicas in radius.
643
64426th January 2006 John Allison (opengl-V08-00-01)
645- Coworks with visman-V08-00-04 (removed fModified).
646- Removed references to fModified.
647- Tidying: Removed unnecessary ClearView.
648- G4OpenGLSceneHandler.cc: Added some (commented out) code for
649 possible future implementation of 2D drawing.
650- G4OpenGLXViewer.cc: Improved exception printing.
651
65211th January 2006 John Allison (opengl-V08-00-00)
653- Improved efficiency: all DrawView's:
654 o Don't call ClearView.
655 o Set flag so SetView will not be called in ProcessView.
656 o Leave background colour to ClearView.
657- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
658- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
659 for current viewer.
660
66124th November 2005 John Allison (opengl-V07-01-09)
662- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
663
66422nd November 2005 John Allison (opengl-V07-01-08)
665- Added G4OpenGLXmViewerMessenger.
666- Corrected text position.
667- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
668
66917th November 2005 Gabriele Cosmo
670- Fixed settings of background style for WIN32 viewers.
671
67213th November 2005 John Allison (opengl-V07-01-07)
673- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
674
67513th October 2005 John Allison (opengl-V07-01-06)
676- Allowed any colour background.
677- Implemented non-uniform scaling.
678- Migration to <sstream>.
679
68029th September 2005 John Allison (opengl-V07-01-05)
681- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
682 scene handler.
683- Re-implemented transparency button in OpenGLXm.
684
68513th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
686- Implemented white background for all OGL viewers.
687- G4OpenGLSceneHandler.cc:
688 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
689 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
690 o Corrected GetTextColour(text).
691 o Corrected GetColour(polyhedron).
692
6935th September 2005 John Allison (opengl-V07-01-03)
694- Bug fix: stored transparent objects were being lost.
695
6962nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
697- Bug fix: edgeflags problem introduced with smooth shading in
698 opengl-V07-01-00.
699- Implementation of a "better algorithm" for the rendering of
700 transparent polyhedron objects. It renders all opaque objects
701 first, then renders the transparent objects with the depth buffer in
702 read-only mode (see OpenGL Programming Guide). It uses the new
703 facility in G4VSceneHandler::ProcessScene for an optional second pass
704 of the run-duration models in the scene. Note this algorithm is
705 still only an approximation. It will still give the wrong blended
706 colour if two transparent objects are rendered front first. For
707 nested transparent objects, this is unfortunate, because
708 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
709 in such a way that mothers come first. Also, there is no guaranteed
710 relationship between the order of rendering and the depth of two
711 transparent objects if they are at the same level or in different
712 branches of the hierarchy. Still, the only error will be an
713 incorrect colour - the objects will still give the appearance of
714 transparency, so it's a pretty good algorithm. (An even better
715 algorithm would be to attempt to render the facets in depth order,
716 deepest first. But how do you calculate the depth - centre of area,
717 deepest corner? One can still imagine pathalogical cases that would
718 sometimes give the wrong colour. Also, for stored mode, the order
719 is fixed in a display list so when the user rotates the view, one
720 would lose the depth ordering. I think we have to accept that
721 blending in OpenGL is only ever an approximation. For accurate
722 blending, use RayTracer.)
723
72428th August 2005 John Allison (opengl-V07-01-01)
725- Half-way implementation of rendering of transparent polyhedron
726 objects. In this implementation, no account is taken of the order
727 of rendering. Transparent objects are rendered with depth testing
728 off so that objects behind can still be seen. But this means that
729 opaque objects in front do not obscure them - and they jolly well
730 should! A better algorithm is to render all opaque objects first,
731 then render the transparent objects with the depth buffer in
732 read-only mode (see OpenGL Programming Guide). This is going to
733 take a little more thought - see opengl-V07-01-02.
734
73520th July 2005 John Allison (opengl-V07-01-00)
736- Introduced smooth shading, taking advantage of hitherto un-noticed
737 feature of HepPolyhedron::GetNextFacet that calculates the normals
738 at each vertex so that curved surfaces are rendered more
739 realistically (Gouraud shading).
740- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
741- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
742 the default window size. It used to be 400x400, hardcoded in
743 G4OpenGLXmViewer.cc, but now it picks up the
744 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
745 The user may change it on the command line, e.g:
746 /vis/open OGLSXm 500
747 or
748 /vis/viewer/create ! ! 500
749
75030th May 2005 John Allison (opengl-V07-00-03)
751- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
752 map of vectors in G4OpenGLFontBaseStore.)
753
7544th May 2005 John Allison (opengl-V07-00-02)
755- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
756 was taken out to prevent recursive calling, but that seems to be OK,
757 and it is needed to implement refresh at end of event/run.)
758
75922nd April 2005 John Allison (opengl-V07-00-01)
760- Rationalised work of opengl-V07-00-00. Functionality unchanged.
761 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
762 o In all concrete viewers, added call to CreateFontLists().
763 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
764 o There is no longer a need to implement in the XmViewer, since it
765 now inherits. Thus the font code now only appears once for X.
766 o Awaiting implementation for WIN32.
767
76817th April 2005 John Allison (opengl-V07-00-00)
769- Based on vis-V07-00-13.
770- Implemented text for X-Windows viewers. Uses glXUseXFont, which
771 creates display lists for nominated fonts. Simple-minded scheme in
772 which each viewer creates its own font display lists for a variety
773 of sizes, which are accessed by the scene handler through a new
774 class, G4OpenGLFontBaseStore. Affected methods:
775 G4OpenGLXViewer::CreateMainWindow()
776 G4OpenGLXmViewer::CreateMainWindow()
777 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
778
77918th November 2004 John Allison (opengl-V06-02-07)
780- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
781
78215th November 2004 Guy Barrand
783- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
784 to see trajectories (for example with N03). Correct so that
785 ShowView do a FinishView that does : glFlush, wglSwapBuffer
786 and empty the Windows message queue.
787
78822nd September 2004 John Allison (opengl-V06-02-06)
789- doxygen output to tmp area.
790- Trap non-regular polyhedrons.
791
79213th September 2004 Gabriele Cosmo (opengl-V06-02-05)
793- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
794 to allow for porting on CLHEP-1.9.X series.
795
79623rd July 2004 John Allison
797- Draws auxiliary edges if required.
798- Added auxiliary edge button.
799
80016th July 2004 John Allison (opengl-V06-02-04)
801- Refinements to hidden line, hidden surface removal.
802
80314th July 2004 John Allison (opengl-V06-02-03)
804- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
805
80613th July 2004 John Allison (opengl-V06-02-02)
807- Hidden line *and* hidden surface removal now works.
808
8099th July 2004 John Allison (opengl-V06-02-01)
810- Fixed long-standing problem with hidden line removal.
811- Improved messages on failure to get visual.
812- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
813 systems provided by default anyway, so no effect.
814
8151st July 2004 John Allison (opengl-V06-02-00)
816- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
817- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
818
81918th June 2004 Gunter Folger (geant4-06-02)
8209th June 2004 Gabriele Cosmo (vis-V06-01-03)
8217th June 2004 Gabriele Cosmo (vis-V06-01-02)
822- GNUmakefile and disclaimer changes - see visualization/History.
823
8249th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
825- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
826
8277th April 2004 Guy Barrand
828- visualization/OpenGL/* : use the G4OpenGL.hh file.
829- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
830 the include of gl/gl.h and gl/glu.h that may be platform dependant.
831 It permits to rm some #ifdef WIN32 spread in the code. It opens also
832 the way to the usage of the Apple OpenGL on a Mac.
833
83417th February 2004 John Allison (opengl-V06-00-00)
835- Fixed bug #581: wrong order of statements in
836 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
837
8384th October 2003 Gabriele Cosmo (vis-V05-02-01)
839- GNUmakefile:
840 o replaced "digits+hits" with "digits_hits".
841- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
842
84322nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
844- Cosmetic change to regularise names:
845 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
846 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
847
84823rd June 2003 Guy Barrand (opengl-V05-01-02)
849- Commit a first implementation of G4OpenGLWin32Viewer.
850
85110th June 2003 Gabriele Cosmo (opengl-V05-01-01)
852- More fixes for warnings in viewers classes.
853- Added inclusion of <windows.h> for WIN32 platforms when GL headers
854 are included.
855
85605th June 2003 Gabriele Cosmo (opengl-V05-01-00)
857- Fixes for porting compilation on WIN32:
858 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
859 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
860 since declared 'obsolete' in WIN32 platforms.
861
86227th November 2002 John Allison (vis-V04-01-08)
863- Improved algorithm of CompareForKernelVisit.
864
86511th November 2002 John Allison (opengl-V04-01-02)
866- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
867- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
868 call default but there as a marker and encourager.
869- Added tracking and digits+hits/hits to GNUmakefile.
870
87116th October 2002 John Allison (opengl-V04-01-01)
872- Fix for WIN32. Now compiles but viewer not implemented.
873
87424th June 2002 John Allison (opengl-V04-01-00)
875- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
876
87710th June 2002 John Allison (opengl-V04-00-03)
878- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
879
8806th June 2002 John Allison (opengl-V04-00-02)
881- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
882
88323rd February 2002 John Allison (opengl-V04-00-01)
884- Changes to encourage compilation on Windows in preparation for
885 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
886 glx.h, unistd.h and assert.h.
887
88824th August 2001 John Allison (vis-V03-02-13)
889- Limited the printing of warnings in
890 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
891
89214th August 2001 John Allison (vis-V03-02-11)
893- Improved KernelVisitDecision.
894- Fixed a few small bugs in multiple "stored" viewers, but see next item.
895- There's an outstanding bug in OpenGL Stored. If there is more than
896 one viewer controlled by a scene handler, after a ClearStore on the
897 scene handler, e.g., with /vis/scene/notifyHandlers, the first
898 viewer to get refreshed should trigger the display list rebuild, but
899 the second need not. However, when the second viewer's turn comes,
900 the display lists are there, and are called, e.g.,
901 G4OpenGLStoredXViewer::DrawView calls
902 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
903 nothing appears on the screen. To overcome this there is some
904 temporary code in G4VViewer::NeedKernelVisit which marks *all*
905 viewers to force a rebuild. To see the symptoms, comment out that
906 temporary code and issue these commands:
907 /vis/verbose c
908 /control/verbose 2
909 /vis/scene/create
910 /vis/scene/add/volume
911 /vis/sceneHandler/create OGLSX
912 /vis/viewer/create ! ! 1
913 /run/beamOn
914 /vis/viewer/create ! ! 1
915 /vis/viewer/select viewer-0
916 /vis/viewer/viewpointThetaPhi 20 20
917 /vis/viewer/select viewer-1

926 You may have to do this too:

929 One of the viewers is empty. Curious!!

9319th August 2001 John Allison (vis-V03-02-10-00)
932- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
933- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
934 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
935 picked up by inheritance anyway.
936- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
937- Corrected order of calling base class functions in
938 G4OpenGLStoredSceneHandler::Begin/EndModeling.
939
94024th July 2001 John Allison (vis-V03-02-06)
941- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
942
94314th July 2001 John Allison (opengl-V03-02-00)
944- Fixed crash in optimised mode: added Initialise() to viewers so
945 that windows are opened after viewers are fully constructed.

9472nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
948- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
949
9507th March 2001 John Allison
951- Changed char* to const char* in many places and that gave problems in
952 calls to Xt and Xm. Hope all's OK. Differences:

95525th January 2001 John Allison (opengl-V03-00-00)
956- Implemented running re-calculation of up-vector in the case of "object
957 rotation" (lights move with camera) to prevent "flipping" of view when
958 camera passes through up-vector. Note that the default is "camera
959 rotation" (lights do not move with camera, i.e., remain fixed relative
960 to object) so the default is that this "flipping" can happen. To set
961 "object rotation" (lights move with camera) use
962 /vis/lights/move_with_camera true (soon to be
963 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
964 on Rotation Panel in OpenGLXm mode.
965- Changed some objects to references for efficiency. E.g.:
966 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
967
96822nd May 2000 John Allison (opengl-V01-01-00)
969- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
970 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
971 static XVisualInfo* vi_single_buffer;
972 static XVisualInfo* vi_double_buffer;
973- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
974 G4OpenGLXViewer.
975- Protected double deletion of window in destructors of G4OpenGLXmViewer
976 and G4OpenGLXViewer (Guy Barrand).
977- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
978- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
979 constructors.
