328    and "/vis/ogl/printEPS").
329
3308th May 2007  John Allison  (opengl-V08-02-06)
331- Moved vectored PostScript printing to G4OpenGLViewer.
332- /vis/ogl/printEPS should work for all viewers, including Win32.
333- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
334  effective on X windows (and still somewhat buggy).
335
3364th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
337- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
338  for OGL*Win32.  Still doesn't work for OGL*Xm.
339
3403rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
341- G4OpenGLStoredSceneHandler:
342  o Re-organised display lists on a per-primitive basis, i.e., one
343    display list per primitive.  (This is so that, except for text,
344    the colour - or, rather, intensity - can be brought out of the
345    display list into the TOList (Transient Object List) and
346    controlled for the Display-by-Time feature.  Previously, if more
347    than one primitive were drawn between BeginPrimitives and
348    EndPrimitives, it would finish up all in one display list, colour
349    commands included. Rationalises and fixes a rare bug in the
350    Display-by-Time feature - see August 2006.)
351  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
352    one primoitive to fit with the above re-organisation.
353- Implemented picking for OGLIX.
354
35525th March 2007  John Allison  (opengl-V08-02-03)
356- Fix compiler warnings.
357
3588th February 2007  John Allison  (opengl-V08-02-02)
359- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
360- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
361  .but not switched back.  Not serious, because context was always set
362  before normal drawing.)
363
3649th January 2007  John Allison  (opengl-V08-02-01)
365- Implemented bitmap markers for MarkerSizeType == screen.  (The old
366  polygon implementation remains for MarkerSizeType == world.)
367- Added G4OpenGLBitMapStore to assist the above.
368- G4OpenGLXViewer::CreateGLXContext:
369  o Bug fix: Added missing break in colormap lookup routine.
370
3715th January 2007  John Allison  (opengl-V08-02-00)
372- G4OpenGLSceneHandler.cc:
373  o Followed change of signature of GetLineWidth in visman-V08-02-00.
374  o Minor efficiency improvements.
375

377- Fixed compiler warnings.
378
3791st November 2006  John Allison  (opengl-V08-01-08)
380- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
381  actually initiates a print, rather than set a flag for printing.
382
38324th October 2006  John Allison  (opengl-V08-01-07)
384- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

386
38719th September 2006  John Allison  (opengl-V08-01-06)
388- Added time origin for light front.
389- Added /vis/ogl/set/transparency.
390- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
391
3924th September 2006  John Allison  (opengl-V08-01-05)
393- Implement cutaways.
394- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
395  primitives (see detector being drawn).
396- /vis/oglx/set/printEPS: change parameter default to true.
397
39830th August 2006  John Allison  (opengl-V08-01-04)
399- G4OpenGLSceneHandler:
400  o Implemented line width.
401  o Switched off back face culling when clipping so that the inside of
402    volumes can be seen.
403  o Added CreateSection/CutawayPolyhedron to exploit generic
404    sectioning (DCUT) and cutaways.  Currently not activated due to
405    instabilities in BooleanProcessor.  Local sectioning still active
406    but broken (at least on Mac) due to apparent change in effect of
407    clipping planes (polyhedron edges not reconstructed).
408  o Rationalised calculation of marker size.
409- G4OpenGLStoredSceneHandler:
410  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
411  o Pick up time range from G4VisAttributes.
412- G4OpenGLViewer(Messenger):
413  o Added position and colour to /vis/ogl/set/displayHeadTime.
414  o Added /vis/ogl/set/displayLightFront.
415- G4OpenGLStoredViewer.cc:
416  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
417  o Added position and colour to DisplayHeadTime.
418  o Added DisplayLightFront.
419 
42016th August 2006  John Allison  (opengl-V08-01-03)
421- Corrected Solaris compilation error.
422- Added /vis/ogl/set/fade and displayHeadTime.
423
42414th August 2006  John Allison  (opengl-V08-01-02)
425- Needs visman-V08-01-02.
426- G4OpenGLStored: Implemented display-by-time.  Only available in
427  stored mode at present.  Only implemented for circle, square,
428  polyline and polymarker at present, enough for currently available
429  trajectory models.  Time is communicated via G4AttValues.
430- Added G4OpenGLViewerMessenger.
431- Added /vis/ogl/set/startTime and endTime of displayed objects.
432- All factories: Instantiated G4OpenGLViewerMessenger.
433- G4OpenGLViewer: Added fStart/EndTime.
434- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
435  spewPrimitiveEPS and spewSortedFeedback.
436
43717th July  John Allison  (opengl-V08-01-01)
438- Added /vis/oglx/set/printEPS (prints eps file on every update).
439
4403rd July 2006  John Allison  (opengl-V08-01-00)
441- Elimination of redundant variable doublebuffer and implementation of
442  FinishView in all viewers.

445- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
446  variable seems to have random behavior and should be assumed false for
447  this viewer.
448
44929th May 2006  Joseph Perl  (opengl-V08-00-07)
450- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
451  Removed common FinishView and instead made separate FinishView for the two different
452  versions of this viewer since each wants a different buffer swapping behaviour.
453
45412th May 2006  John Allison  (opengl-V08-00-06)
455- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
456
45728th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
458- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
459  recomputing transients.
460
46124th April 2006  John Allison  (opengl-V08-00-04)
462- Fixed compilation problem on Windows.
463
46419th April 2006  John Allison  (opengl-V08-00-03)
465- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
466  G4OpenGLImmediateSceneHandler:
467  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
468    greps-V08-00-02).
469  o Migrated to direct access to G4PhysicalVolumeModel.
470- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
471  of display lists in DrawView.
472
47314th March 2006  John Allison  (opengl-V08-00-02)
474- Refined display list building and re-drawing algorithm.
475  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
476  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
477- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
478  re-use algorithm.  In test19 with global culling off, numbers of
479  display lists used are:
480  o 191  No re-use:
481  o  73  Before this change: re-use except replicas (includes parameterised).
482  o  33  After this change: re-use except parameterised and replicas in radius.
483
48426th January 2006  John Allison  (opengl-V08-00-01)
485- Coworks with visman-V08-00-04 (removed fModified).
486- Removed references to fModified.
487- Tidying: Removed unnecessary ClearView.
488- G4OpenGLSceneHandler.cc: Added some (commented out) code for
489  possible future implementation of 2D drawing.
490- G4OpenGLXViewer.cc: Improved exception printing.
491
49211th January 2006  John Allison  (opengl-V08-00-00)
493- Improved efficiency: all DrawView's:
494  o Don't call ClearView.
495  o Set flag so SetView will not be called in ProcessView.
496  o Leave background colour to ClearView.
497- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
498- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
499  for current viewer.
500
50124th November 2005  John Allison  (opengl-V07-01-09)
502- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
503
50422nd November 2005  John Allison  (opengl-V07-01-08)
505- Added G4OpenGLXmViewerMessenger.
506- Corrected text position.
507- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
508
50917th November 2005  Gabriele Cosmo
510- Fixed settings of background style for WIN32 viewers.
511
51213th November 2005  John Allison  (opengl-V07-01-07)
513- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
514
51513th October 2005  John Allison  (opengl-V07-01-06)
516- Allowed any colour background.
517- Implemented non-uniform scaling.
518- Migration to <sstream>.
519
52029th September 2005  John Allison  (opengl-V07-01-05)
521- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
522  scene handler.
523- Re-implemented transparency button in OpenGLXm.
524
52513th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
526- Implemented white background for all OGL viewers.
527- G4OpenGLSceneHandler.cc:
528  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
529  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
530  o Corrected GetTextColour(text).
531  o Corrected GetColour(polyhedron).
532
5335th September 2005  John Allison  (opengl-V07-01-03)
534- Bug fix: stored transparent objects were being lost.
535
5362nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
537- Bug fix: edgeflags problem introduced with smooth shading in
538  opengl-V07-01-00.
539- Implementation of a "better algorithm" for the rendering of
540  transparent polyhedron objects.  It renders all opaque objects
541  first, then renders the transparent objects with the depth buffer in
542  read-only mode (see OpenGL Programming Guide).  It uses the new
543  facility in G4VSceneHandler::ProcessScene for an optional second pass
544  of the run-duration models in the scene.  Note this algorithm is
545  still only an approximation.  It will still give the wrong blended
546  colour if two transparent objects are rendered front first.  For
547  nested transparent objects, this is unfortunate, because
548  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
549  in such a way that mothers come first.  Also, there is no guaranteed
550  relationship between the order of rendering and the depth of two
551  transparent objects if they are at the same level or in different
552  branches of the hierarchy.  Still, the only error will be an
553  incorrect colour - the objects will still give the appearance of
554  transparency, so it's a pretty good algorithm.  (An even better
555  algorithm would be to attempt to render the facets in depth order,
556  deepest first.  But how do you calculate the depth - centre of area,
557  deepest corner?  One can still imagine pathalogical cases that would
558  sometimes give the wrong colour.  Also, for stored mode, the order
559  is fixed in a display list so when the user rotates the view, one
560  would lose the depth ordering.  I think we have to accept that
561  blending in OpenGL is only ever an approximation.  For accurate
562  blending, use RayTracer.)
563
56428th August 2005  John Allison  (opengl-V07-01-01)
565- Half-way implementation of rendering of transparent polyhedron
566  objects.  In this implementation, no account is taken of the order
567  of rendering.  Transparent objects are rendered with depth testing
568  off so that objects behind can still be seen.  But this means that
569  opaque objects in front do not obscure them - and they jolly well
570  should!  A better algorithm is to render all opaque objects first,
571  then render the transparent objects with the depth buffer in
572  read-only mode (see OpenGL Programming Guide).  This is going to
573  take a little more thought - see opengl-V07-01-02.
574
57520th July 2005  John Allison  (opengl-V07-01-00)
576- Introduced smooth shading, taking advantage of hitherto un-noticed
577  feature of HepPolyhedron::GetNextFacet that calculates the normals
578  at each vertex so that curved surfaces are rendered more
579  realistically (Gouraud shading).
580- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
581- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
582  the default window size.  It used to be 400x400, hardcoded in
583  G4OpenGLXmViewer.cc, but now it picks up the
584  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
585  The user may change it on the command line, e.g:
586    /vis/open OGLSXm 500
587  or
588    /vis/viewer/create ! ! 500
589
59030th May 2005  John Allison  (opengl-V07-00-03)
591- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
592  map of vectors in G4OpenGLFontBaseStore.)
593
5944th May 2005  John Allison  (opengl-V07-00-02)
595- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
596  was taken out to prevent recursive calling, but that seems to be OK,
597  and it is needed to implement refresh at end of event/run.)
598
59922nd April 2005  John Allison  (opengl-V07-00-01)
600- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
601  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
602  o In all concrete viewers, added call to CreateFontLists().
603  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
604  o There is no longer a need to implement in the XmViewer, since it
605    now inherits.  Thus the font code now only appears once for X.
606  o Awaiting implementation for WIN32.
607
60817th April 2005  John Allison  (opengl-V07-00-00)
609- Based on vis-V07-00-13.
610- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
611  creates display lists for nominated fonts.  Simple-minded scheme in
612  which each viewer creates its own font display lists for a variety
613  of sizes, which are accessed by the scene handler through a new
614  class, G4OpenGLFontBaseStore.  Affected methods:
615    G4OpenGLXViewer::CreateMainWindow()
616    G4OpenGLXmViewer::CreateMainWindow()
617    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
618
61918th November 2004  John Allison  (opengl-V06-02-07)
620- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
621
62215th November 2004  Guy Barrand
623- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
624  to see trajectories (for example with N03). Correct so that
625  ShowView do a FinishView that does : glFlush, wglSwapBuffer
626  and empty the Windows message queue.
627
62822nd September 2004  John Allison  (opengl-V06-02-06)
629- doxygen output to tmp area.
630- Trap non-regular polyhedrons.
631
63213th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
633- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
634  to allow for porting on CLHEP-1.9.X series.
635
63623rd July 2004  John Allison
637- Draws auxiliary edges if required.
638- Added auxiliary edge button.
639
64016th July 2004  John Allison  (opengl-V06-02-04)
641- Refinements to hidden line, hidden surface removal.
642
64314th July 2004  John Allison  (opengl-V06-02-03)
644- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
645
64613th July 2004  John Allison  (opengl-V06-02-02)
647- Hidden line *and* hidden surface removal now works.
648
6499th July 2004  John Allison  (opengl-V06-02-01)
650- Fixed long-standing problem with hidden line removal.
651- Improved messages on failure to get visual.
652- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
653  systems provided by default anyway, so no effect.
654
6551st July 2004  John Allison  (opengl-V06-02-00)
656- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
657- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
658
65918th June 2004  Gunter Folger (geant4-06-02)
6609th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6617th June 2004  Gabriele Cosmo  (vis-V06-01-02)
662- GNUmakefile and disclaimer changes - see visualization/History.
663
6649th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
665- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
666
6677th April 2004  Guy Barrand
668- visualization/OpenGL/* : use the G4OpenGL.hh file.
669- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
670  the include of gl/gl.h and gl/glu.h that may be platform dependant.
671  It permits to rm some #ifdef WIN32 spread in the code. It opens also
672  the way to the usage of the Apple OpenGL on a Mac.
673
67417th February 2004  John Allison  (opengl-V06-00-00)
675- Fixed bug #581: wrong order of statements in
676  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
677
6784th October 2003  Gabriele Cosmo  (vis-V05-02-01)
679- GNUmakefile:
680  o replaced "digits+hits" with "digits_hits".
681- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
682
68322nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
684- Cosmetic change to regularise names:
685  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
686  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
687
68823rd June 2003  Guy Barrand  (opengl-V05-01-02)
689- Commit a first implementation of G4OpenGLWin32Viewer.
690
69110th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
692- More fixes for warnings in viewers classes.
693- Added inclusion of <windows.h> for WIN32 platforms when GL headers
694  are included.
695
69605th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
697- Fixes for porting compilation on WIN32:
698  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
699  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
700    since declared 'obsolete' in WIN32 platforms.
701
70227th November 2002  John Allison  (vis-V04-01-08)
703- Improved algorithm of CompareForKernelVisit.
704
70511th November 2002  John Allison  (opengl-V04-01-02)
706- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
707- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
708  call default but there as a marker and encourager.
709- Added tracking and digits+hits/hits to GNUmakefile.
710
71116th October 2002  John Allison  (opengl-V04-01-01)
712- Fix for WIN32.  Now compiles but viewer not implemented.
713
71424th June 2002  John Allison  (opengl-V04-01-00)
715- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
716
71710th June 2002  John Allison  (opengl-V04-00-03)
718- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
719
7206th June 2002  John Allison  (opengl-V04-00-02)
721- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
722
72323rd February 2002  John Allison  (opengl-V04-00-01)
724- Changes to encourage compilation on Windows in preparation for
725  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
726  glx.h, unistd.h and assert.h.
727
72824th August 2001  John Allison  (vis-V03-02-13)
729- Limited the printing of warnings in
730  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
731
73214th August 2001  John Allison  (vis-V03-02-11)
733- Improved KernelVisitDecision.
734- Fixed a few small bugs in multiple "stored" viewers, but see next item.
735- There's an outstanding bug in OpenGL Stored.  If there is more than
736  one viewer controlled by a scene handler, after a ClearStore on the
737  scene handler, e.g., with /vis/scene/notifyHandlers, the first
738  viewer to get refreshed should trigger the display list rebuild, but
739  the second need not.  However, when the second viewer's turn comes,
740  the display lists are there, and are called, e.g.,
741  G4OpenGLStoredXViewer::DrawView calls
742  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
743  nothing appears on the screen.  To overcome this there is some
744  temporary code in G4VViewer::NeedKernelVisit which marks *all*
745  viewers to force a rebuild.  To see the symptoms, comment out that
746  temporary code and issue these commands:
747    /vis/verbose c
748    /control/verbose 2
749    /vis/scene/create
750    /vis/scene/add/volume
751    /vis/sceneHandler/create OGLSX
752    /vis/viewer/create ! ! 1
753    /run/beamOn
754    /vis/viewer/create ! ! 1
755    /vis/viewer/select viewer-0
756    /vis/viewer/viewpointThetaPhi 20 20
757    /vis/viewer/select viewer-1
758    /vis/viewer/viewpointThetaPhi 40 40
759    /vis/viewer/set/style surface
760    /vis/viewer/refresh
761    /vis/viewer/select viewer-0
762    /vis/viewer/refresh
763    /vis/viewer/select viewer-1
764    /vis/viewer/set/style wireframe
765    /vis/scene/notifyHandlers
766  You may have to do this too:
767    /vis/viewer/select viewer-0
768    /vis/scene/notifyHandlers
769  One of the viewers is empty.  Curious!!
770
7719th August 2001  John Allison  (vis-V03-02-10-00)
772- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
773- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
774  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
775  picked up by inheritance anyway.
776- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
777- Corrected order of calling base class functions in
778  G4OpenGLStoredSceneHandler::Begin/EndModeling.
779
78024th July 2001  John Allison  (vis-V03-02-06)
781- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
782
78314th July 2001  John Allison (opengl-V03-02-00)
784- Fixed crash in optimised mode: added Initialise() to viewers so
785  that windows are opened after viewers are fully constructed.
786
7872nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
788- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
789
7907th March 2001  John Allison
791- Changed char* to const char* in many places and that gave problems in
792  calls to Xt and Xm.  Hope all's OK.  Differences:
793    cvs diff -r vis-V03-00-06 vis-V03-00-07
794
79525th January 2001  John Allison  (opengl-V03-00-00)
796- Implemented running re-calculation of up-vector in the case of "object
797  rotation" (lights move with camera) to prevent "flipping" of view when
798  camera passes through up-vector.  Note that the default is "camera
799  rotation" (lights do not move with camera, i.e., remain fixed relative
800  to object) so the default is that this "flipping" can happen.  To set
801  "object rotation" (lights move with camera) use
802  /vis/lights/move_with_camera true (soon to be
803  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
804  on Rotation Panel in OpenGLXm mode.
805- Changed some objects to references for efficiency.  E.g.:
806  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
807
80822nd May 2000  John Allison  (opengl-V01-01-00)
809- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
810  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
811    static XVisualInfo* vi_single_buffer;
812    static XVisualInfo* vi_double_buffer;
813- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
814  G4OpenGLXViewer.
815- Protected double deletion of window in destructors of G4OpenGLXmViewer
816  and G4OpenGLXViewer (Guy Barrand).
817- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
818- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
819  constructors.
Note: See TracBrowser for help on using the repository browser.
