360    and "/vis/ogl/printEPS").
361
3628th May 2007  John Allison  (opengl-V08-02-06)
363- Moved vectored PostScript printing to G4OpenGLViewer.
364- /vis/ogl/printEPS should work for all viewers, including Win32.
365- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
366  effective on X windows (and still somewhat buggy).
367
3684th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
369- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
370  for OGL*Win32.  Still doesn't work for OGL*Xm.
371
3723rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
373- G4OpenGLStoredSceneHandler:
374  o Re-organised display lists on a per-primitive basis, i.e., one
375    display list per primitive.  (This is so that, except for text,
376    the colour - or, rather, intensity - can be brought out of the
377    display list into the TOList (Transient Object List) and
378    controlled for the Display-by-Time feature.  Previously, if more
379    than one primitive were drawn between BeginPrimitives and
380    EndPrimitives, it would finish up all in one display list, colour
381    commands included. Rationalises and fixes a rare bug in the
382    Display-by-Time feature - see August 2006.)
383  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
384    one primoitive to fit with the above re-organisation.
385- Implemented picking for OGLIX.
386
38725th March 2007  John Allison  (opengl-V08-02-03)
388- Fix compiler warnings.
389
3908th February 2007  John Allison  (opengl-V08-02-02)
391- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
392- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
393  .but not switched back.  Not serious, because context was always set
394  before normal drawing.)
395
3969th January 2007  John Allison  (opengl-V08-02-01)
397- Implemented bitmap markers for MarkerSizeType == screen.  (The old
398  polygon implementation remains for MarkerSizeType == world.)
399- Added G4OpenGLBitMapStore to assist the above.
400- G4OpenGLXViewer::CreateGLXContext:
401  o Bug fix: Added missing break in colormap lookup routine.
402
4035th January 2007  John Allison  (opengl-V08-02-00)
404- G4OpenGLSceneHandler.cc:
405  o Followed change of signature of GetLineWidth in visman-V08-02-00.
406  o Minor efficiency improvements.
407
40821st November 2006  John Allison  (opengl-V08-01-09)
409- Fixed compiler warnings.
410
4111st November 2006  John Allison  (opengl-V08-01-08)
412- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
413  actually initiates a print, rather than set a flag for printing.
414
41524th October 2006  John Allison  (opengl-V08-01-07)
416- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
417- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
418
41919th September 2006  John Allison  (opengl-V08-01-06)
420- Added time origin for light front.
421- Added /vis/ogl/set/transparency.
422- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
423
4244th September 2006  John Allison  (opengl-V08-01-05)
425- Implement cutaways.
426- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
427  primitives (see detector being drawn).
428- /vis/oglx/set/printEPS: change parameter default to true.
429
43030th August 2006  John Allison  (opengl-V08-01-04)
431- G4OpenGLSceneHandler:
432  o Implemented line width.
433  o Switched off back face culling when clipping so that the inside of
434    volumes can be seen.
435  o Added CreateSection/CutawayPolyhedron to exploit generic
436    sectioning (DCUT) and cutaways.  Currently not activated due to
437    instabilities in BooleanProcessor.  Local sectioning still active
438    but broken (at least on Mac) due to apparent change in effect of
439    clipping planes (polyhedron edges not reconstructed).
440  o Rationalised calculation of marker size.
441- G4OpenGLStoredSceneHandler:
442  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
443  o Pick up time range from G4VisAttributes.
444- G4OpenGLViewer(Messenger):
445  o Added position and colour to /vis/ogl/set/displayHeadTime.
446  o Added /vis/ogl/set/displayLightFront.
447- G4OpenGLStoredViewer.cc:
448  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
449  o Added position and colour to DisplayHeadTime.
450  o Added DisplayLightFront.
451 
45216th August 2006  John Allison  (opengl-V08-01-03)
453- Corrected Solaris compilation error.
454- Added /vis/ogl/set/fade and displayHeadTime.
455
45614th August 2006  John Allison  (opengl-V08-01-02)
457- Needs visman-V08-01-02.
458- G4OpenGLStored: Implemented display-by-time.  Only available in
459  stored mode at present.  Only implemented for circle, square,
460  polyline and polymarker at present, enough for currently available
461  trajectory models.  Time is communicated via G4AttValues.
462- Added G4OpenGLViewerMessenger.
463- Added /vis/ogl/set/startTime and endTime of displayed objects.
464- All factories: Instantiated G4OpenGLViewerMessenger.
465- G4OpenGLViewer: Added fStart/EndTime.
466- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
467  spewPrimitiveEPS and spewSortedFeedback.
468
46917th July  John Allison  (opengl-V08-01-01)
470- Added /vis/oglx/set/printEPS (prints eps file on every update).
471
4723rd July 2006  John Allison  (opengl-V08-01-00)
473- Elimination of redundant variable doublebuffer and implementation of
474  FinishView in all viewers.
475
47630th May 2006  Joseph Perl  (opengl-V08-00-08)
477- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
478  variable seems to have random behavior and should be assumed false for
479  this viewer.
480
48129th May 2006  Joseph Perl  (opengl-V08-00-07)
482- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
483  Removed common FinishView and instead made separate FinishView for the two different
484  versions of this viewer since each wants a different buffer swapping behaviour.
485
48612th May 2006  John Allison  (opengl-V08-00-06)
487- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
488
48928th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
490- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
491  recomputing transients.
492
49324th April 2006  John Allison  (opengl-V08-00-04)
494- Fixed compilation problem on Windows.
495
49619th April 2006  John Allison  (opengl-V08-00-03)
497- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
498  G4OpenGLImmediateSceneHandler:
499  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
500    greps-V08-00-02).
501  o Migrated to direct access to G4PhysicalVolumeModel.
502- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
503  of display lists in DrawView.
504
50514th March 2006  John Allison  (opengl-V08-00-02)
506- Refined display list building and re-drawing algorithm.
507  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
508  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
509- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
510  re-use algorithm.  In test19 with global culling off, numbers of
511  display lists used are:
512  o 191  No re-use:
513  o  73  Before this change: re-use except replicas (includes parameterised).
514  o  33  After this change: re-use except parameterised and replicas in radius.
515
51626th January 2006  John Allison  (opengl-V08-00-01)
517- Coworks with visman-V08-00-04 (removed fModified).
518- Removed references to fModified.
519- Tidying: Removed unnecessary ClearView.
520- G4OpenGLSceneHandler.cc: Added some (commented out) code for
521  possible future implementation of 2D drawing.
522- G4OpenGLXViewer.cc: Improved exception printing.
523
52411th January 2006  John Allison  (opengl-V08-00-00)
525- Improved efficiency: all DrawView's:
526  o Don't call ClearView.
527  o Set flag so SetView will not be called in ProcessView.
528  o Leave background colour to ClearView.
529- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
530- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
531  for current viewer.
532
53324th November 2005  John Allison  (opengl-V07-01-09)
534- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
535
53622nd November 2005  John Allison  (opengl-V07-01-08)
537- Added G4OpenGLXmViewerMessenger.
538- Corrected text position.
539- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
540
54117th November 2005  Gabriele Cosmo
542- Fixed settings of background style for WIN32 viewers.
543
54413th November 2005  John Allison  (opengl-V07-01-07)
545- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
546
54713th October 2005  John Allison  (opengl-V07-01-06)
548- Allowed any colour background.
549- Implemented non-uniform scaling.
550- Migration to <sstream>.
551
55229th September 2005  John Allison  (opengl-V07-01-05)
553- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
554  scene handler.
555- Re-implemented transparency button in OpenGLXm.
556
55713th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
558- Implemented white background for all OGL viewers.
559- G4OpenGLSceneHandler.cc:
560  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
561  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
562  o Corrected GetTextColour(text).
563  o Corrected GetColour(polyhedron).
564
5655th September 2005  John Allison  (opengl-V07-01-03)
566- Bug fix: stored transparent objects were being lost.
567
5682nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
569- Bug fix: edgeflags problem introduced with smooth shading in
570  opengl-V07-01-00.
571- Implementation of a "better algorithm" for the rendering of
572  transparent polyhedron objects.  It renders all opaque objects
573  first, then renders the transparent objects with the depth buffer in
574  read-only mode (see OpenGL Programming Guide).  It uses the new
575  facility in G4VSceneHandler::ProcessScene for an optional second pass
576  of the run-duration models in the scene.  Note this algorithm is
577  still only an approximation.  It will still give the wrong blended
578  colour if two transparent objects are rendered front first.  For
579  nested transparent objects, this is unfortunate, because
580  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
581  in such a way that mothers come first.  Also, there is no guaranteed
582  relationship between the order of rendering and the depth of two
583  transparent objects if they are at the same level or in different
584  branches of the hierarchy.  Still, the only error will be an
585  incorrect colour - the objects will still give the appearance of
586  transparency, so it's a pretty good algorithm.  (An even better
587  algorithm would be to attempt to render the facets in depth order,
588  deepest first.  But how do you calculate the depth - centre of area,
589  deepest corner?  One can still imagine pathalogical cases that would
590  sometimes give the wrong colour.  Also, for stored mode, the order
591  is fixed in a display list so when the user rotates the view, one
592  would lose the depth ordering.  I think we have to accept that
593  blending in OpenGL is only ever an approximation.  For accurate
594  blending, use RayTracer.)
595
59628th August 2005  John Allison  (opengl-V07-01-01)
597- Half-way implementation of rendering of transparent polyhedron
598  objects.  In this implementation, no account is taken of the order
599  of rendering.  Transparent objects are rendered with depth testing
600  off so that objects behind can still be seen.  But this means that
601  opaque objects in front do not obscure them - and they jolly well
602  should!  A better algorithm is to render all opaque objects first,
603  then render the transparent objects with the depth buffer in
604  read-only mode (see OpenGL Programming Guide).  This is going to
605  take a little more thought - see opengl-V07-01-02.
606
60720th July 2005  John Allison  (opengl-V07-01-00)
608- Introduced smooth shading, taking advantage of hitherto un-noticed
609  feature of HepPolyhedron::GetNextFacet that calculates the normals
610  at each vertex so that curved surfaces are rendered more
611  realistically (Gouraud shading).
612- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
613- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
614  the default window size.  It used to be 400x400, hardcoded in
615  G4OpenGLXmViewer.cc, but now it picks up the
616  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
617  The user may change it on the command line, e.g:
618    /vis/open OGLSXm 500
619  or
620    /vis/viewer/create ! ! 500
621
62230th May 2005  John Allison  (opengl-V07-00-03)
623- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
624  map of vectors in G4OpenGLFontBaseStore.)
625
6264th May 2005  John Allison  (opengl-V07-00-02)
627- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
628  was taken out to prevent recursive calling, but that seems to be OK,
629  and it is needed to implement refresh at end of event/run.)
630
63122nd April 2005  John Allison  (opengl-V07-00-01)
632- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
633  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
634  o In all concrete viewers, added call to CreateFontLists().
635  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
636  o There is no longer a need to implement in the XmViewer, since it
637    now inherits.  Thus the font code now only appears once for X.
638  o Awaiting implementation for WIN32.
639
64017th April 2005  John Allison  (opengl-V07-00-00)
641- Based on vis-V07-00-13.
642- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
643  creates display lists for nominated fonts.  Simple-minded scheme in
644  which each viewer creates its own font display lists for a variety
645  of sizes, which are accessed by the scene handler through a new
646  class, G4OpenGLFontBaseStore.  Affected methods:
647    G4OpenGLXViewer::CreateMainWindow()
648    G4OpenGLXmViewer::CreateMainWindow()
649    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
650
65118th November 2004  John Allison  (opengl-V06-02-07)
652- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
653
65415th November 2004  Guy Barrand
655- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
656  to see trajectories (for example with N03). Correct so that
657  ShowView do a FinishView that does : glFlush, wglSwapBuffer
658  and empty the Windows message queue.
659
66022nd September 2004  John Allison  (opengl-V06-02-06)
661- doxygen output to tmp area.
662- Trap non-regular polyhedrons.
663
66413th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
665- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
666  to allow for porting on CLHEP-1.9.X series.
667
66823rd July 2004  John Allison
669- Draws auxiliary edges if required.
670- Added auxiliary edge button.
671
67216th July 2004  John Allison  (opengl-V06-02-04)
673- Refinements to hidden line, hidden surface removal.
674
67514th July 2004  John Allison  (opengl-V06-02-03)
676- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
677
67813th July 2004  John Allison  (opengl-V06-02-02)
679- Hidden line *and* hidden surface removal now works.
680
6819th July 2004  John Allison  (opengl-V06-02-01)
682- Fixed long-standing problem with hidden line removal.
683- Improved messages on failure to get visual.
684- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
685  systems provided by default anyway, so no effect.
686
6871st July 2004  John Allison  (opengl-V06-02-00)
688- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
689- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
690
69118th June 2004  Gunter Folger (geant4-06-02)
6929th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6937th June 2004  Gabriele Cosmo  (vis-V06-01-02)
694- GNUmakefile and disclaimer changes - see visualization/History.
695
6969th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
697- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
698
6997th April 2004  Guy Barrand
700- visualization/OpenGL/* : use the G4OpenGL.hh file.
701- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
702  the include of gl/gl.h and gl/glu.h that may be platform dependant.
703  It permits to rm some #ifdef WIN32 spread in the code. It opens also
704  the way to the usage of the Apple OpenGL on a Mac.
705
70617th February 2004  John Allison  (opengl-V06-00-00)
707- Fixed bug #581: wrong order of statements in
708  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
709
7104th October 2003  Gabriele Cosmo  (vis-V05-02-01)
711- GNUmakefile:
712  o replaced "digits+hits" with "digits_hits".
713- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
714
71522nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
716- Cosmetic change to regularise names:
717  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
718  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
719
72023rd June 2003  Guy Barrand  (opengl-V05-01-02)
721- Commit a first implementation of G4OpenGLWin32Viewer.
722
72310th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
724- More fixes for warnings in viewers classes.
725- Added inclusion of <windows.h> for WIN32 platforms when GL headers
726  are included.
727
72805th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
729- Fixes for porting compilation on WIN32:
730  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
731  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
732    since declared 'obsolete' in WIN32 platforms.
733
73427th November 2002  John Allison  (vis-V04-01-08)
735- Improved algorithm of CompareForKernelVisit.
736
73711th November 2002  John Allison  (opengl-V04-01-02)
738- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
739- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
740  call default but there as a marker and encourager.
741- Added tracking and digits+hits/hits to GNUmakefile.
742
74316th October 2002  John Allison  (opengl-V04-01-01)
744- Fix for WIN32.  Now compiles but viewer not implemented.
745
74624th June 2002  John Allison  (opengl-V04-01-00)
747- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
748
74910th June 2002  John Allison  (opengl-V04-00-03)
750- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
751
7526th June 2002  John Allison  (opengl-V04-00-02)
753- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
754
75523rd February 2002  John Allison  (opengl-V04-00-01)
756- Changes to encourage compilation on Windows in preparation for
757  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
758  glx.h, unistd.h and assert.h.
759
76024th August 2001  John Allison  (vis-V03-02-13)
761- Limited the printing of warnings in
762  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
763
76414th August 2001  John Allison  (vis-V03-02-11)
765- Improved KernelVisitDecision.
766- Fixed a few small bugs in multiple "stored" viewers, but see next item.
767- There's an outstanding bug in OpenGL Stored.  If there is more than
768  one viewer controlled by a scene handler, after a ClearStore on the
769  scene handler, e.g., with /vis/scene/notifyHandlers, the first
770  viewer to get refreshed should trigger the display list rebuild, but
771  the second need not.  However, when the second viewer's turn comes,
772  the display lists are there, and are called, e.g.,
773  G4OpenGLStoredXViewer::DrawView calls
774  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
775  nothing appears on the screen.  To overcome this there is some
776  temporary code in G4VViewer::NeedKernelVisit which marks *all*
777  viewers to force a rebuild.  To see the symptoms, comment out that
778  temporary code and issue these commands:
779    /vis/verbose c
780    /control/verbose 2
781    /vis/scene/create
782    /vis/scene/add/volume
783    /vis/sceneHandler/create OGLSX
784    /vis/viewer/create ! ! 1
785    /run/beamOn
786    /vis/viewer/create ! ! 1
787    /vis/viewer/select viewer-0
788    /vis/viewer/viewpointThetaPhi 20 20
789    /vis/viewer/select viewer-1
790    /vis/viewer/viewpointThetaPhi 40 40
791    /vis/viewer/set/style surface
792    /vis/viewer/refresh
793    /vis/viewer/select viewer-0
794    /vis/viewer/refresh
795    /vis/viewer/select viewer-1
796    /vis/viewer/set/style wireframe
797    /vis/scene/notifyHandlers
798  You may have to do this too:
799    /vis/viewer/select viewer-0
800    /vis/scene/notifyHandlers
801  One of the viewers is empty.  Curious!!
802
8039th August 2001  John Allison  (vis-V03-02-10-00)
804- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
805- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
806  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
807  picked up by inheritance anyway.
808- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
809- Corrected order of calling base class functions in
810  G4OpenGLStoredSceneHandler::Begin/EndModeling.
811
81224th July 2001  John Allison  (vis-V03-02-06)
813- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
814
81514th July 2001  John Allison (opengl-V03-02-00)
816- Fixed crash in optimised mode: added Initialise() to viewers so
817  that windows are opened after viewers are fully constructed.
818
8192nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
820- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
821
8227th March 2001  John Allison
823- Changed char* to const char* in many places and that gave problems in
824  calls to Xt and Xm.  Hope all's OK.  Differences:
825    cvs diff -r vis-V03-00-06 vis-V03-00-07
826
82725th January 2001  John Allison  (opengl-V03-00-00)
828- Implemented running re-calculation of up-vector in the case of "object
829  rotation" (lights move with camera) to prevent "flipping" of view when
830  camera passes through up-vector.  Note that the default is "camera
831  rotation" (lights do not move with camera, i.e., remain fixed relative
832  to object) so the default is that this "flipping" can happen.  To set
833  "object rotation" (lights move with camera) use
834  /vis/lights/move_with_camera true (soon to be
835  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
836  on Rotation Panel in OpenGLXm mode.
837- Changed some objects to references for efficiency.  E.g.:
838  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
839
84022nd May 2000  John Allison  (opengl-V01-01-00)
841- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
842  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
843    static XVisualInfo* vi_single_buffer;
844    static XVisualInfo* vi_double_buffer;
845- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
846  G4OpenGLXViewer.
847- Protected double deletion of window in destructors of G4OpenGLXmViewer
848  and G4OpenGLXViewer (Guy Barrand).
849- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
850- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
851  constructors.
Note: See TracBrowser for help on using the repository browser.
