295  o Correct path /vis/ogl/set/printMode.
296  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
297    and "/vis/ogl/printEPS").
298
2998th May 2007  John Allison  (opengl-V08-02-06)
300- Moved vectored PostScript printing to G4OpenGLViewer.
301- /vis/ogl/printEPS should work for all viewers, including Win32.
302- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
303  effective on X windows (and still somewhat buggy).
304
3054th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
306- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
307  for OGL*Win32.  Still doesn't work for OGL*Xm.
308
3093rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
310- G4OpenGLStoredSceneHandler:
311  o Re-organised display lists on a per-primitive basis, i.e., one
312    display list per primitive.  (This is so that, except for text,
313    the colour - or, rather, intensity - can be brought out of the
314    display list into the TOList (Transient Object List) and
315    controlled for the Display-by-Time feature.  Previously, if more
316    than one primitive were drawn between BeginPrimitives and
317    EndPrimitives, it would finish up all in one display list, colour
318    commands included. Rationalises and fixes a rare bug in the
319    Display-by-Time feature - see August 2006.)
320  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
321    one primoitive to fit with the above re-organisation.
322- Implemented picking for OGLIX.
323
32425th March 2007  John Allison  (opengl-V08-02-03)
325- Fix compiler warnings.
326
3278th February 2007  John Allison  (opengl-V08-02-02)
328- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
329- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
330  .but not switched back.  Not serious, because context was always set
331  before normal drawing.)
332
3339th January 2007  John Allison  (opengl-V08-02-01)
334- Implemented bitmap markers for MarkerSizeType == screen.  (The old
335  polygon implementation remains for MarkerSizeType == world.)
336- Added G4OpenGLBitMapStore to assist the above.
337- G4OpenGLXViewer::CreateGLXContext:
338  o Bug fix: Added missing break in colormap lookup routine.
339
3405th January 2007  John Allison  (opengl-V08-02-00)
341- G4OpenGLSceneHandler.cc:
342  o Followed change of signature of GetLineWidth in visman-V08-02-00.
343  o Minor efficiency improvements.
344
34521st November 2006  John Allison  (opengl-V08-01-09)
346- Fixed compiler warnings.
347
3481st November 2006  John Allison  (opengl-V08-01-08)
349- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
350  actually initiates a print, rather than set a flag for printing.
351
35224th October 2006  John Allison  (opengl-V08-01-07)
353- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

355
35619th September 2006  John Allison  (opengl-V08-01-06)
357- Added time origin for light front.
358- Added /vis/ogl/set/transparency.
359- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
360
3614th September 2006  John Allison  (opengl-V08-01-05)
362- Implement cutaways.
363- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
364  primitives (see detector being drawn).
365- /vis/oglx/set/printEPS: change parameter default to true.
366
36730th August 2006  John Allison  (opengl-V08-01-04)
368- G4OpenGLSceneHandler:
369  o Implemented line width.
370  o Switched off back face culling when clipping so that the inside of
371    volumes can be seen.
372  o Added CreateSection/CutawayPolyhedron to exploit generic
373    sectioning (DCUT) and cutaways.  Currently not activated due to
374    instabilities in BooleanProcessor.  Local sectioning still active
375    but broken (at least on Mac) due to apparent change in effect of
376    clipping planes (polyhedron edges not reconstructed).
377  o Rationalised calculation of marker size.
378- G4OpenGLStoredSceneHandler:
379  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
380  o Pick up time range from G4VisAttributes.
381- G4OpenGLViewer(Messenger):
382  o Added position and colour to /vis/ogl/set/displayHeadTime.
383  o Added /vis/ogl/set/displayLightFront.
384- G4OpenGLStoredViewer.cc:
385  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
386  o Added position and colour to DisplayHeadTime.
387  o Added DisplayLightFront.
388 
38916th August 2006  John Allison  (opengl-V08-01-03)
390- Corrected Solaris compilation error.
391- Added /vis/ogl/set/fade and displayHeadTime.
392
39314th August 2006  John Allison  (opengl-V08-01-02)
394- Needs visman-V08-01-02.
395- G4OpenGLStored: Implemented display-by-time.  Only available in
396  stored mode at present.  Only implemented for circle, square,
397  polyline and polymarker at present, enough for currently available
398  trajectory models.  Time is communicated via G4AttValues.
399- Added G4OpenGLViewerMessenger.
400- Added /vis/ogl/set/startTime and endTime of displayed objects.
401- All factories: Instantiated G4OpenGLViewerMessenger.
402- G4OpenGLViewer: Added fStart/EndTime.
403- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
404  spewPrimitiveEPS and spewSortedFeedback.
405
40617th July  John Allison  (opengl-V08-01-01)
407- Added /vis/oglx/set/printEPS (prints eps file on every update).
408
4093rd July 2006  John Allison  (opengl-V08-01-00)
410- Elimination of redundant variable doublebuffer and implementation of
411  FinishView in all viewers.
412
41330th May 2006  Joseph Perl  (opengl-V08-00-08)
414- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
415  variable seems to have random behavior and should be assumed false for
416  this viewer.
417
41829th May 2006  Joseph Perl  (opengl-V08-00-07)
419- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
420  Removed common FinishView and instead made separate FinishView for the two different
421  versions of this viewer since each wants a different buffer swapping behaviour.
422
42312th May 2006  John Allison  (opengl-V08-00-06)
424- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
425
42628th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
427- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
428  recomputing transients.

434- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
435  G4OpenGLImmediateSceneHandler:
436  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
437    greps-V08-00-02).
438  o Migrated to direct access to G4PhysicalVolumeModel.
439- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
440  of display lists in DrawView.
441
44214th March 2006  John Allison  (opengl-V08-00-02)
443- Refined display list building and re-drawing algorithm.
444  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
445  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
446- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
447  re-use algorithm.  In test19 with global culling off, numbers of
448  display lists used are:
449  o 191  No re-use:
450  o  73  Before this change: re-use except replicas (includes parameterised).
451  o  33  After this change: re-use except parameterised and replicas in radius.
452
45326th January 2006  John Allison  (opengl-V08-00-01)
454- Coworks with visman-V08-00-04 (removed fModified).
455- Removed references to fModified.
456- Tidying: Removed unnecessary ClearView.
457- G4OpenGLSceneHandler.cc: Added some (commented out) code for
458  possible future implementation of 2D drawing.
459- G4OpenGLXViewer.cc: Improved exception printing.
460
46111th January 2006  John Allison  (opengl-V08-00-00)
462- Improved efficiency: all DrawView's:
463  o Don't call ClearView.
464  o Set flag so SetView will not be called in ProcessView.
465  o Leave background colour to ClearView.
466- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
467- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
468  for current viewer.
469
47024th November 2005  John Allison  (opengl-V07-01-09)
471- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
472
47322nd November 2005  John Allison  (opengl-V07-01-08)
474- Added G4OpenGLXmViewerMessenger.
475- Corrected text position.
476- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
477
47817th November 2005  Gabriele Cosmo
479- Fixed settings of background style for WIN32 viewers.
480
48113th November 2005  John Allison  (opengl-V07-01-07)
482- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
483
48413th October 2005  John Allison  (opengl-V07-01-06)
485- Allowed any colour background.
486- Implemented non-uniform scaling.
487- Migration to <sstream>.
488
48929th September 2005  John Allison  (opengl-V07-01-05)
490- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
491  scene handler.
492- Re-implemented transparency button in OpenGLXm.
493
49413th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
495- Implemented white background for all OGL viewers.
496- G4OpenGLSceneHandler.cc:
497  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
498  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
499  o Corrected GetTextColour(text).
500  o Corrected GetColour(polyhedron).
501
5025th September 2005  John Allison  (opengl-V07-01-03)
503- Bug fix: stored transparent objects were being lost.
504
5052nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
506- Bug fix: edgeflags problem introduced with smooth shading in
507  opengl-V07-01-00.
508- Implementation of a "better algorithm" for the rendering of
509  transparent polyhedron objects.  It renders all opaque objects
510  first, then renders the transparent objects with the depth buffer in
511  read-only mode (see OpenGL Programming Guide).  It uses the new
512  facility in G4VSceneHandler::ProcessScene for an optional second pass
513  of the run-duration models in the scene.  Note this algorithm is
514  still only an approximation.  It will still give the wrong blended
515  colour if two transparent objects are rendered front first.  For
516  nested transparent objects, this is unfortunate, because
517  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
518  in such a way that mothers come first.  Also, there is no guaranteed
519  relationship between the order of rendering and the depth of two
520  transparent objects if they are at the same level or in different
521  branches of the hierarchy.  Still, the only error will be an
522  incorrect colour - the objects will still give the appearance of
523  transparency, so it's a pretty good algorithm.  (An even better
524  algorithm would be to attempt to render the facets in depth order,
525  deepest first.  But how do you calculate the depth - centre of area,
526  deepest corner?  One can still imagine pathalogical cases that would
527  sometimes give the wrong colour.  Also, for stored mode, the order
528  is fixed in a display list so when the user rotates the view, one
529  would lose the depth ordering.  I think we have to accept that
530  blending in OpenGL is only ever an approximation.  For accurate
531  blending, use RayTracer.)
532
53328th August 2005  John Allison  (opengl-V07-01-01)
534- Half-way implementation of rendering of transparent polyhedron
535  objects.  In this implementation, no account is taken of the order
536  of rendering.  Transparent objects are rendered with depth testing
537  off so that objects behind can still be seen.  But this means that
538  opaque objects in front do not obscure them - and they jolly well
539  should!  A better algorithm is to render all opaque objects first,
540  then render the transparent objects with the depth buffer in
541  read-only mode (see OpenGL Programming Guide).  This is going to
542  take a little more thought - see opengl-V07-01-02.
543
54420th July 2005  John Allison  (opengl-V07-01-00)
545- Introduced smooth shading, taking advantage of hitherto un-noticed
546  feature of HepPolyhedron::GetNextFacet that calculates the normals
547  at each vertex so that curved surfaces are rendered more
548  realistically (Gouraud shading).
549- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
550- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
551  the default window size.  It used to be 400x400, hardcoded in
552  G4OpenGLXmViewer.cc, but now it picks up the
553  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
554  The user may change it on the command line, e.g:
555    /vis/open OGLSXm 500
556  or
557    /vis/viewer/create ! ! 500
558
55930th May 2005  John Allison  (opengl-V07-00-03)
560- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
561  map of vectors in G4OpenGLFontBaseStore.)
562
5634th May 2005  John Allison  (opengl-V07-00-02)
564- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
565  was taken out to prevent recursive calling, but that seems to be OK,
566  and it is needed to implement refresh at end of event/run.)
567
56822nd April 2005  John Allison  (opengl-V07-00-01)
569- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
570  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
571  o In all concrete viewers, added call to CreateFontLists().
572  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
573  o There is no longer a need to implement in the XmViewer, since it
574    now inherits.  Thus the font code now only appears once for X.
575  o Awaiting implementation for WIN32.
576
57717th April 2005  John Allison  (opengl-V07-00-00)
578- Based on vis-V07-00-13.
579- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
580  creates display lists for nominated fonts.  Simple-minded scheme in
581  which each viewer creates its own font display lists for a variety
582  of sizes, which are accessed by the scene handler through a new
583  class, G4OpenGLFontBaseStore.  Affected methods:
584    G4OpenGLXViewer::CreateMainWindow()
585    G4OpenGLXmViewer::CreateMainWindow()
586    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
587
58818th November 2004  John Allison  (opengl-V06-02-07)
589- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
590
59115th November 2004  Guy Barrand
592- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
593  to see trajectories (for example with N03). Correct so that
594  ShowView do a FinishView that does : glFlush, wglSwapBuffer
595  and empty the Windows message queue.
596
59722nd September 2004  John Allison  (opengl-V06-02-06)
598- doxygen output to tmp area.
599- Trap non-regular polyhedrons.
600
60113th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
602- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
603  to allow for porting on CLHEP-1.9.X series.
604
60523rd July 2004  John Allison
606- Draws auxiliary edges if required.
607- Added auxiliary edge button.
608
60916th July 2004  John Allison  (opengl-V06-02-04)
610- Refinements to hidden line, hidden surface removal.
611
61214th July 2004  John Allison  (opengl-V06-02-03)
613- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
614
61513th July 2004  John Allison  (opengl-V06-02-02)
616- Hidden line *and* hidden surface removal now works.
617
6189th July 2004  John Allison  (opengl-V06-02-01)
619- Fixed long-standing problem with hidden line removal.
620- Improved messages on failure to get visual.
621- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
622  systems provided by default anyway, so no effect.
623
6241st July 2004  John Allison  (opengl-V06-02-00)
625- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
626- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
627
62818th June 2004  Gunter Folger (geant4-06-02)
6299th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6307th June 2004  Gabriele Cosmo  (vis-V06-01-02)
631- GNUmakefile and disclaimer changes - see visualization/History.
632
6339th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
634- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
635
6367th April 2004  Guy Barrand
637- visualization/OpenGL/* : use the G4OpenGL.hh file.
638- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
639  the include of gl/gl.h and gl/glu.h that may be platform dependant.
640  It permits to rm some #ifdef WIN32 spread in the code. It opens also
641  the way to the usage of the Apple OpenGL on a Mac.
642
64317th February 2004  John Allison  (opengl-V06-00-00)
644- Fixed bug #581: wrong order of statements in
645  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
646
6474th October 2003  Gabriele Cosmo  (vis-V05-02-01)
648- GNUmakefile:
649  o replaced "digits+hits" with "digits_hits".
650- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
651
65222nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
653- Cosmetic change to regularise names:
654  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
655  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
656
65723rd June 2003  Guy Barrand  (opengl-V05-01-02)
658- Commit a first implementation of G4OpenGLWin32Viewer.
659
66010th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
661- More fixes for warnings in viewers classes.
662- Added inclusion of <windows.h> for WIN32 platforms when GL headers
663  are included.
664
66505th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
666- Fixes for porting compilation on WIN32:
667  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
668  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
669    since declared 'obsolete' in WIN32 platforms.
670
67127th November 2002  John Allison  (vis-V04-01-08)
672- Improved algorithm of CompareForKernelVisit.
673
67411th November 2002  John Allison  (opengl-V04-01-02)
675- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
676- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
677  call default but there as a marker and encourager.
678- Added tracking and digits+hits/hits to GNUmakefile.
679
68016th October 2002  John Allison  (opengl-V04-01-01)
681- Fix for WIN32.  Now compiles but viewer not implemented.
682
68324th June 2002  John Allison  (opengl-V04-01-00)
684- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
685
68610th June 2002  John Allison  (opengl-V04-00-03)
687- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
688
6896th June 2002  John Allison  (opengl-V04-00-02)
690- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
691
69223rd February 2002  John Allison  (opengl-V04-00-01)
693- Changes to encourage compilation on Windows in preparation for
694  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
695  glx.h, unistd.h and assert.h.
696
69724th August 2001  John Allison  (vis-V03-02-13)
698- Limited the printing of warnings in
699  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
700
70114th August 2001  John Allison  (vis-V03-02-11)
702- Improved KernelVisitDecision.
703- Fixed a few small bugs in multiple "stored" viewers, but see next item.
704- There's an outstanding bug in OpenGL Stored.  If there is more than
705  one viewer controlled by a scene handler, after a ClearStore on the
706  scene handler, e.g., with /vis/scene/notifyHandlers, the first
707  viewer to get refreshed should trigger the display list rebuild, but
708  the second need not.  However, when the second viewer's turn comes,
709  the display lists are there, and are called, e.g.,
710  G4OpenGLStoredXViewer::DrawView calls
711  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
712  nothing appears on the screen.  To overcome this there is some
713  temporary code in G4VViewer::NeedKernelVisit which marks *all*
714  viewers to force a rebuild.  To see the symptoms, comment out that
715  temporary code and issue these commands:
716    /vis/verbose c
717    /control/verbose 2
718    /vis/scene/create
719    /vis/scene/add/volume
720    /vis/sceneHandler/create OGLSX
721    /vis/viewer/create ! ! 1
722    /run/beamOn
723    /vis/viewer/create ! ! 1
724    /vis/viewer/select viewer-0
725    /vis/viewer/viewpointThetaPhi 20 20
726    /vis/viewer/select viewer-1
727    /vis/viewer/viewpointThetaPhi 40 40
728    /vis/viewer/set/style surface
729    /vis/viewer/refresh
730    /vis/viewer/select viewer-0
731    /vis/viewer/refresh
732    /vis/viewer/select viewer-1
733    /vis/viewer/set/style wireframe
734    /vis/scene/notifyHandlers
735  You may have to do this too:
736    /vis/viewer/select viewer-0
737    /vis/scene/notifyHandlers
738  One of the viewers is empty.  Curious!!
739
7409th August 2001  John Allison  (vis-V03-02-10-00)
741- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
742- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
743  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
744  picked up by inheritance anyway.
745- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
746- Corrected order of calling base class functions in
747  G4OpenGLStoredSceneHandler::Begin/EndModeling.
748
74924th July 2001  John Allison  (vis-V03-02-06)
750- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
751
75214th July 2001  John Allison (opengl-V03-02-00)
753- Fixed crash in optimised mode: added Initialise() to viewers so
754  that windows are opened after viewers are fully constructed.
755
7562nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
757- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
758
7597th March 2001  John Allison
760- Changed char* to const char* in many places and that gave problems in
761  calls to Xt and Xm.  Hope all's OK.  Differences:
762    cvs diff -r vis-V03-00-06 vis-V03-00-07
763
76425th January 2001  John Allison  (opengl-V03-00-00)
765- Implemented running re-calculation of up-vector in the case of "object
766  rotation" (lights move with camera) to prevent "flipping" of view when
767  camera passes through up-vector.  Note that the default is "camera
768  rotation" (lights do not move with camera, i.e., remain fixed relative
769  to object) so the default is that this "flipping" can happen.  To set
770  "object rotation" (lights move with camera) use
771  /vis/lights/move_with_camera true (soon to be
772  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
773  on Rotation Panel in OpenGLXm mode.
774- Changed some objects to references for efficiency.  E.g.:
775  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
776
77722nd May 2000  John Allison  (opengl-V01-01-00)
778- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
779  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
780    static XVisualInfo* vi_single_buffer;
781    static XVisualInfo* vi_double_buffer;
782- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
783  G4OpenGLXViewer.
784- Protected double deletion of window in destructors of G4OpenGLXmViewer
785  and G4OpenGLXViewer (Guy Barrand).
786- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
787- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
788  constructors.
Note: See TracBrowser for help on using the repository browser.
