331    and "/vis/ogl/printEPS").
332
3338th May 2007  John Allison  (opengl-V08-02-06)
334- Moved vectored PostScript printing to G4OpenGLViewer.
335- /vis/ogl/printEPS should work for all viewers, including Win32.
336- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
337  effective on X windows (and still somewhat buggy).
338
3394th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
340- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
341  for OGL*Win32.  Still doesn't work for OGL*Xm.
342
3433rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
344- G4OpenGLStoredSceneHandler:
345  o Re-organised display lists on a per-primitive basis, i.e., one
346    display list per primitive.  (This is so that, except for text,
347    the colour - or, rather, intensity - can be brought out of the
348    display list into the TOList (Transient Object List) and
349    controlled for the Display-by-Time feature.  Previously, if more
350    than one primitive were drawn between BeginPrimitives and
351    EndPrimitives, it would finish up all in one display list, colour
352    commands included. Rationalises and fixes a rare bug in the
353    Display-by-Time feature - see August 2006.)
354  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
355    one primoitive to fit with the above re-organisation.
356- Implemented picking for OGLIX.
357
35825th March 2007  John Allison  (opengl-V08-02-03)
359- Fix compiler warnings.
360
3618th February 2007  John Allison  (opengl-V08-02-02)
362- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
363- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
364  .but not switched back.  Not serious, because context was always set
365  before normal drawing.)
366
3679th January 2007  John Allison  (opengl-V08-02-01)
368- Implemented bitmap markers for MarkerSizeType == screen.  (The old
369  polygon implementation remains for MarkerSizeType == world.)
370- Added G4OpenGLBitMapStore to assist the above.
371- G4OpenGLXViewer::CreateGLXContext:
372  o Bug fix: Added missing break in colormap lookup routine.
373
3745th January 2007  John Allison  (opengl-V08-02-00)
375- G4OpenGLSceneHandler.cc:
376  o Followed change of signature of GetLineWidth in visman-V08-02-00.
377  o Minor efficiency improvements.
378

380- Fixed compiler warnings.
381
3821st November 2006  John Allison  (opengl-V08-01-08)
383- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
384  actually initiates a print, rather than set a flag for printing.
385
38624th October 2006  John Allison  (opengl-V08-01-07)
387- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

389
39019th September 2006  John Allison  (opengl-V08-01-06)
391- Added time origin for light front.
392- Added /vis/ogl/set/transparency.
393- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
394
3954th September 2006  John Allison  (opengl-V08-01-05)
396- Implement cutaways.
397- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
398  primitives (see detector being drawn).
399- /vis/oglx/set/printEPS: change parameter default to true.
400
40130th August 2006  John Allison  (opengl-V08-01-04)
402- G4OpenGLSceneHandler:
403  o Implemented line width.
404  o Switched off back face culling when clipping so that the inside of
405    volumes can be seen.
406  o Added CreateSection/CutawayPolyhedron to exploit generic
407    sectioning (DCUT) and cutaways.  Currently not activated due to
408    instabilities in BooleanProcessor.  Local sectioning still active
409    but broken (at least on Mac) due to apparent change in effect of
410    clipping planes (polyhedron edges not reconstructed).
411  o Rationalised calculation of marker size.
412- G4OpenGLStoredSceneHandler:
413  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
414  o Pick up time range from G4VisAttributes.
415- G4OpenGLViewer(Messenger):
416  o Added position and colour to /vis/ogl/set/displayHeadTime.
417  o Added /vis/ogl/set/displayLightFront.
418- G4OpenGLStoredViewer.cc:
419  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
420  o Added position and colour to DisplayHeadTime.
421  o Added DisplayLightFront.
422 
42316th August 2006  John Allison  (opengl-V08-01-03)
424- Corrected Solaris compilation error.
425- Added /vis/ogl/set/fade and displayHeadTime.
426
42714th August 2006  John Allison  (opengl-V08-01-02)
428- Needs visman-V08-01-02.
429- G4OpenGLStored: Implemented display-by-time.  Only available in
430  stored mode at present.  Only implemented for circle, square,
431  polyline and polymarker at present, enough for currently available
432  trajectory models.  Time is communicated via G4AttValues.
433- Added G4OpenGLViewerMessenger.
434- Added /vis/ogl/set/startTime and endTime of displayed objects.
435- All factories: Instantiated G4OpenGLViewerMessenger.
436- G4OpenGLViewer: Added fStart/EndTime.
437- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
438  spewPrimitiveEPS and spewSortedFeedback.
439
44017th July  John Allison  (opengl-V08-01-01)
441- Added /vis/oglx/set/printEPS (prints eps file on every update).

4433rd July 2006  John Allison  (opengl-V08-01-00)
444- Elimination of redundant variable doublebuffer and implementation of
445  FinishView in all viewers.
446
44730th May 2006  Joseph Perl  (opengl-V08-00-08)
448- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
449  variable seems to have random behavior and should be assumed false for
450  this viewer.
451
45229th May 2006  Joseph Perl  (opengl-V08-00-07)
453- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
454  Removed common FinishView and instead made separate FinishView for the two different
455  versions of this viewer since each wants a different buffer swapping behaviour.
456
45712th May 2006  John Allison  (opengl-V08-00-06)
458- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
459
46028th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
461- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
462  recomputing transients.
463
46424th April 2006  John Allison  (opengl-V08-00-04)
465- Fixed compilation problem on Windows.
466
46719th April 2006  John Allison  (opengl-V08-00-03)
468- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
469  G4OpenGLImmediateSceneHandler:
470  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
471    greps-V08-00-02).
472  o Migrated to direct access to G4PhysicalVolumeModel.
473- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
474  of display lists in DrawView.
475
47614th March 2006  John Allison  (opengl-V08-00-02)
477- Refined display list building and re-drawing algorithm.
478  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
479  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
480- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
481  re-use algorithm.  In test19 with global culling off, numbers of
482  display lists used are:
483  o 191  No re-use:
484  o  73  Before this change: re-use except replicas (includes parameterised).
485  o  33  After this change: re-use except parameterised and replicas in radius.
486
48726th January 2006  John Allison  (opengl-V08-00-01)
488- Coworks with visman-V08-00-04 (removed fModified).
489- Removed references to fModified.
490- Tidying: Removed unnecessary ClearView.
491- G4OpenGLSceneHandler.cc: Added some (commented out) code for
492  possible future implementation of 2D drawing.
493- G4OpenGLXViewer.cc: Improved exception printing.
494
49511th January 2006  John Allison  (opengl-V08-00-00)
496- Improved efficiency: all DrawView's:
497  o Don't call ClearView.
498  o Set flag so SetView will not be called in ProcessView.
499  o Leave background colour to ClearView.
500- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
501- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
502  for current viewer.
503
50424th November 2005  John Allison  (opengl-V07-01-09)
505- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
506
50722nd November 2005  John Allison  (opengl-V07-01-08)
508- Added G4OpenGLXmViewerMessenger.
509- Corrected text position.
510- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
511
51217th November 2005  Gabriele Cosmo
513- Fixed settings of background style for WIN32 viewers.
514
51513th November 2005  John Allison  (opengl-V07-01-07)
516- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
517
51813th October 2005  John Allison  (opengl-V07-01-06)
519- Allowed any colour background.
520- Implemented non-uniform scaling.
521- Migration to <sstream>.
522
52329th September 2005  John Allison  (opengl-V07-01-05)
524- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
525  scene handler.
526- Re-implemented transparency button in OpenGLXm.
527
52813th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
529- Implemented white background for all OGL viewers.
530- G4OpenGLSceneHandler.cc:
531  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
532  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
533  o Corrected GetTextColour(text).
534  o Corrected GetColour(polyhedron).
535
5365th September 2005  John Allison  (opengl-V07-01-03)
537- Bug fix: stored transparent objects were being lost.
538
5392nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
540- Bug fix: edgeflags problem introduced with smooth shading in
541  opengl-V07-01-00.
542- Implementation of a "better algorithm" for the rendering of
543  transparent polyhedron objects.  It renders all opaque objects
544  first, then renders the transparent objects with the depth buffer in
545  read-only mode (see OpenGL Programming Guide).  It uses the new
546  facility in G4VSceneHandler::ProcessScene for an optional second pass
547  of the run-duration models in the scene.  Note this algorithm is
548  still only an approximation.  It will still give the wrong blended
549  colour if two transparent objects are rendered front first.  For
550  nested transparent objects, this is unfortunate, because
551  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
552  in such a way that mothers come first.  Also, there is no guaranteed
553  relationship between the order of rendering and the depth of two
554  transparent objects if they are at the same level or in different
555  branches of the hierarchy.  Still, the only error will be an
556  incorrect colour - the objects will still give the appearance of
557  transparency, so it's a pretty good algorithm.  (An even better
558  algorithm would be to attempt to render the facets in depth order,
559  deepest first.  But how do you calculate the depth - centre of area,
560  deepest corner?  One can still imagine pathalogical cases that would
561  sometimes give the wrong colour.  Also, for stored mode, the order
562  is fixed in a display list so when the user rotates the view, one
563  would lose the depth ordering.  I think we have to accept that
564  blending in OpenGL is only ever an approximation.  For accurate
565  blending, use RayTracer.)
566
56728th August 2005  John Allison  (opengl-V07-01-01)
568- Half-way implementation of rendering of transparent polyhedron
569  objects.  In this implementation, no account is taken of the order
570  of rendering.  Transparent objects are rendered with depth testing
571  off so that objects behind can still be seen.  But this means that
572  opaque objects in front do not obscure them - and they jolly well
573  should!  A better algorithm is to render all opaque objects first,
574  then render the transparent objects with the depth buffer in
575  read-only mode (see OpenGL Programming Guide).  This is going to
576  take a little more thought - see opengl-V07-01-02.
577
57820th July 2005  John Allison  (opengl-V07-01-00)
579- Introduced smooth shading, taking advantage of hitherto un-noticed
580  feature of HepPolyhedron::GetNextFacet that calculates the normals
581  at each vertex so that curved surfaces are rendered more
582  realistically (Gouraud shading).
583- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
584- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
585  the default window size.  It used to be 400x400, hardcoded in
586  G4OpenGLXmViewer.cc, but now it picks up the
587  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
588  The user may change it on the command line, e.g:
589    /vis/open OGLSXm 500
590  or
591    /vis/viewer/create ! ! 500
592
59330th May 2005  John Allison  (opengl-V07-00-03)
594- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
595  map of vectors in G4OpenGLFontBaseStore.)
596
5974th May 2005  John Allison  (opengl-V07-00-02)
598- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
599  was taken out to prevent recursive calling, but that seems to be OK,
600  and it is needed to implement refresh at end of event/run.)
601
60222nd April 2005  John Allison  (opengl-V07-00-01)
603- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
604  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
605  o In all concrete viewers, added call to CreateFontLists().
606  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
607  o There is no longer a need to implement in the XmViewer, since it
608    now inherits.  Thus the font code now only appears once for X.
609  o Awaiting implementation for WIN32.
610
61117th April 2005  John Allison  (opengl-V07-00-00)
612- Based on vis-V07-00-13.
613- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
614  creates display lists for nominated fonts.  Simple-minded scheme in
615  which each viewer creates its own font display lists for a variety
616  of sizes, which are accessed by the scene handler through a new
617  class, G4OpenGLFontBaseStore.  Affected methods:
618    G4OpenGLXViewer::CreateMainWindow()
619    G4OpenGLXmViewer::CreateMainWindow()
620    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
621
62218th November 2004  John Allison  (opengl-V06-02-07)
623- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
624
62515th November 2004  Guy Barrand
626- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
627  to see trajectories (for example with N03). Correct so that
628  ShowView do a FinishView that does : glFlush, wglSwapBuffer
629  and empty the Windows message queue.
630
63122nd September 2004  John Allison  (opengl-V06-02-06)
632- doxygen output to tmp area.
633- Trap non-regular polyhedrons.
634
63513th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
636- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
637  to allow for porting on CLHEP-1.9.X series.
638
63923rd July 2004  John Allison
640- Draws auxiliary edges if required.
641- Added auxiliary edge button.
642
64316th July 2004  John Allison  (opengl-V06-02-04)
644- Refinements to hidden line, hidden surface removal.
645
64614th July 2004  John Allison  (opengl-V06-02-03)
647- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
648
64913th July 2004  John Allison  (opengl-V06-02-02)
650- Hidden line *and* hidden surface removal now works.
651
6529th July 2004  John Allison  (opengl-V06-02-01)
653- Fixed long-standing problem with hidden line removal.
654- Improved messages on failure to get visual.
655- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
656  systems provided by default anyway, so no effect.
657
6581st July 2004  John Allison  (opengl-V06-02-00)
659- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
660- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
661
66218th June 2004  Gunter Folger (geant4-06-02)
6639th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6647th June 2004  Gabriele Cosmo  (vis-V06-01-02)
665- GNUmakefile and disclaimer changes - see visualization/History.
666
6679th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
668- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
669
6707th April 2004  Guy Barrand
671- visualization/OpenGL/* : use the G4OpenGL.hh file.
672- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
673  the include of gl/gl.h and gl/glu.h that may be platform dependant.
674  It permits to rm some #ifdef WIN32 spread in the code. It opens also
675  the way to the usage of the Apple OpenGL on a Mac.
676
67717th February 2004  John Allison  (opengl-V06-00-00)
678- Fixed bug #581: wrong order of statements in
679  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
680
6814th October 2003  Gabriele Cosmo  (vis-V05-02-01)
682- GNUmakefile:
683  o replaced "digits+hits" with "digits_hits".
684- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
685
68622nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
687- Cosmetic change to regularise names:
688  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
689  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
690
69123rd June 2003  Guy Barrand  (opengl-V05-01-02)
692- Commit a first implementation of G4OpenGLWin32Viewer.
693
69410th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
695- More fixes for warnings in viewers classes.
696- Added inclusion of <windows.h> for WIN32 platforms when GL headers
697  are included.
698
69905th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
700- Fixes for porting compilation on WIN32:
701  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
702  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
703    since declared 'obsolete' in WIN32 platforms.
704
70527th November 2002  John Allison  (vis-V04-01-08)
706- Improved algorithm of CompareForKernelVisit.
707
70811th November 2002  John Allison  (opengl-V04-01-02)
709- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
710- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
711  call default but there as a marker and encourager.
712- Added tracking and digits+hits/hits to GNUmakefile.
713
71416th October 2002  John Allison  (opengl-V04-01-01)
715- Fix for WIN32.  Now compiles but viewer not implemented.
716
71724th June 2002  John Allison  (opengl-V04-01-00)
718- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
719
72010th June 2002  John Allison  (opengl-V04-00-03)
721- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
722
7236th June 2002  John Allison  (opengl-V04-00-02)
724- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
725
72623rd February 2002  John Allison  (opengl-V04-00-01)
727- Changes to encourage compilation on Windows in preparation for
728  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
729  glx.h, unistd.h and assert.h.
730
73124th August 2001  John Allison  (vis-V03-02-13)
732- Limited the printing of warnings in
733  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
734
73514th August 2001  John Allison  (vis-V03-02-11)
736- Improved KernelVisitDecision.
737- Fixed a few small bugs in multiple "stored" viewers, but see next item.
738- There's an outstanding bug in OpenGL Stored.  If there is more than
739  one viewer controlled by a scene handler, after a ClearStore on the
740  scene handler, e.g., with /vis/scene/notifyHandlers, the first
741  viewer to get refreshed should trigger the display list rebuild, but
742  the second need not.  However, when the second viewer's turn comes,
743  the display lists are there, and are called, e.g.,
744  G4OpenGLStoredXViewer::DrawView calls
745  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
746  nothing appears on the screen.  To overcome this there is some
747  temporary code in G4VViewer::NeedKernelVisit which marks *all*
748  viewers to force a rebuild.  To see the symptoms, comment out that
749  temporary code and issue these commands:
750    /vis/verbose c
751    /control/verbose 2
752    /vis/scene/create
753    /vis/scene/add/volume
754    /vis/sceneHandler/create OGLSX
755    /vis/viewer/create ! ! 1
756    /run/beamOn
757    /vis/viewer/create ! ! 1
758    /vis/viewer/select viewer-0
759    /vis/viewer/viewpointThetaPhi 20 20
760    /vis/viewer/select viewer-1
761    /vis/viewer/viewpointThetaPhi 40 40
762    /vis/viewer/set/style surface
763    /vis/viewer/refresh
764    /vis/viewer/select viewer-0
765    /vis/viewer/refresh
766    /vis/viewer/select viewer-1
767    /vis/viewer/set/style wireframe
768    /vis/scene/notifyHandlers
769  You may have to do this too:
770    /vis/viewer/select viewer-0
771    /vis/scene/notifyHandlers
772  One of the viewers is empty.  Curious!!
773
7749th August 2001  John Allison  (vis-V03-02-10-00)
775- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
776- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
777  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
778  picked up by inheritance anyway.
779- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
780- Corrected order of calling base class functions in
781  G4OpenGLStoredSceneHandler::Begin/EndModeling.
782
78324th July 2001  John Allison  (vis-V03-02-06)
784- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
785
78614th July 2001  John Allison (opengl-V03-02-00)
787- Fixed crash in optimised mode: added Initialise() to viewers so
788  that windows are opened after viewers are fully constructed.
789
7902nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
791- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
792
7937th March 2001  John Allison
794- Changed char* to const char* in many places and that gave problems in
795  calls to Xt and Xm.  Hope all's OK.  Differences:
796    cvs diff -r vis-V03-00-06 vis-V03-00-07
797
79825th January 2001  John Allison  (opengl-V03-00-00)
799- Implemented running re-calculation of up-vector in the case of "object
800  rotation" (lights move with camera) to prevent "flipping" of view when
801  camera passes through up-vector.  Note that the default is "camera
802  rotation" (lights do not move with camera, i.e., remain fixed relative
803  to object) so the default is that this "flipping" can happen.  To set
804  "object rotation" (lights move with camera) use
805  /vis/lights/move_with_camera true (soon to be
806  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
807  on Rotation Panel in OpenGLXm mode.
808- Changed some objects to references for efficiency.  E.g.:
809  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
810
81122nd May 2000  John Allison  (opengl-V01-01-00)
812- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
813  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
814    static XVisualInfo* vi_single_buffer;
815    static XVisualInfo* vi_double_buffer;
816- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
817  G4OpenGLXViewer.
818- Protected double deletion of window in destructors of G4OpenGLXmViewer
819  and G4OpenGLXViewer (Guy Barrand).
820- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
821- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
822  constructors.
Note: See TracBrowser for help on using the repository browser.
