191 o Correct path /vis/ogl/set/printMode.
192 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
193 and "/vis/ogl/printEPS").
194
1958th May 2007 John Allison (opengl-V08-02-06)
196- Moved vectored PostScript printing to G4OpenGLViewer.
197- /vis/ogl/printEPS should work for all viewers, including Win32.
198- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
199 effective on X windows (and still somewhat buggy).
200
2014th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
202- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
203 for OGL*Win32. Still doesn't work for OGL*Xm.
204
2053rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
206- G4OpenGLStoredSceneHandler:
207 o Re-organised display lists on a per-primitive basis, i.e., one
208 display list per primitive. (This is so that, except for text,
209 the colour - or, rather, intensity - can be brought out of the
210 display list into the TOList (Transient Object List) and
211 controlled for the Display-by-Time feature. Previously, if more
212 than one primitive were drawn between BeginPrimitives and
213 EndPrimitives, it would finish up all in one display list, colour
214 commands included. Rationalises and fixes a rare bug in the
215 Display-by-Time feature - see August 2006.)
216 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
217 one primoitive to fit with the above re-organisation.
218- Implemented picking for OGLIX.
219
22025th March 2007 John Allison (opengl-V08-02-03)
221- Fix compiler warnings.
222
2238th February 2007 John Allison (opengl-V08-02-02)
224- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
225- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
226 .but not switched back. Not serious, because context was always set
227 before normal drawing.)
228
2299th January 2007 John Allison (opengl-V08-02-01)
230- Implemented bitmap markers for MarkerSizeType == screen. (The old
231 polygon implementation remains for MarkerSizeType == world.)
232- Added G4OpenGLBitMapStore to assist the above.
233- G4OpenGLXViewer::CreateGLXContext:
234 o Bug fix: Added missing break in colormap lookup routine.
235
2365th January 2007 John Allison (opengl-V08-02-00)
237- G4OpenGLSceneHandler.cc:
238 o Followed change of signature of GetLineWidth in visman-V08-02-00.
239 o Minor efficiency improvements.
240
24121st November 2006 John Allison (opengl-V08-01-09)
242- Fixed compiler warnings.
243
2441st November 2006 John Allison (opengl-V08-01-08)
245- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
246 actually initiates a print, rather than set a flag for printing.
247
24824th October 2006 John Allison (opengl-V08-01-07)
249- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
250- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
251
25219th September 2006 John Allison (opengl-V08-01-06)

254- Added /vis/ogl/set/transparency.
255- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
256
2574th September 2006 John Allison (opengl-V08-01-05)
258- Implement cutaways.
259- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
260 primitives (see detector being drawn).
261- /vis/oglx/set/printEPS: change parameter default to true.
262
26330th August 2006 John Allison (opengl-V08-01-04)
264- G4OpenGLSceneHandler:
265 o Implemented line width.
266 o Switched off back face culling when clipping so that the inside of
267 volumes can be seen.
268 o Added CreateSection/CutawayPolyhedron to exploit generic
269 sectioning (DCUT) and cutaways. Currently not activated due to
270 instabilities in BooleanProcessor. Local sectioning still active
271 but broken (at least on Mac) due to apparent change in effect of
272 clipping planes (polyhedron edges not reconstructed).
273 o Rationalised calculation of marker size.
274- G4OpenGLStoredSceneHandler:
275 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
276 o Pick up time range from G4VisAttributes.
277- G4OpenGLViewer(Messenger):
278 o Added position and colour to /vis/ogl/set/displayHeadTime.
279 o Added /vis/ogl/set/displayLightFront.
280- G4OpenGLStoredViewer.cc:
281 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
282 o Added position and colour to DisplayHeadTime.
283 o Added DisplayLightFront.
284
28516th August 2006 John Allison (opengl-V08-01-03)
286- Corrected Solaris compilation error.
287- Added /vis/ogl/set/fade and displayHeadTime.
288
28914th August 2006 John Allison (opengl-V08-01-02)
290- Needs visman-V08-01-02.
291- G4OpenGLStored: Implemented display-by-time. Only available in
292 stored mode at present. Only implemented for circle, square,
293 polyline and polymarker at present, enough for currently available
294 trajectory models. Time is communicated via G4AttValues.
295- Added G4OpenGLViewerMessenger.
296- Added /vis/ogl/set/startTime and endTime of displayed objects.
297- All factories: Instantiated G4OpenGLViewerMessenger.
298- G4OpenGLViewer: Added fStart/EndTime.
299- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
300 spewPrimitiveEPS and spewSortedFeedback.
301
30217th July John Allison (opengl-V08-01-01)
303- Added /vis/oglx/set/printEPS (prints eps file on every update).
304
3053rd July 2006 John Allison (opengl-V08-01-00)
306- Elimination of redundant variable doublebuffer and implementation of
307 FinishView in all viewers.
308
30930th May 2006 Joseph Perl (opengl-V08-00-08)
310- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
311 variable seems to have random behavior and should be assumed false for
312 this viewer.
313
31429th May 2006 Joseph Perl (opengl-V08-00-07)
315- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
316 Removed common FinishView and instead made separate FinishView for the two different
317 versions of this viewer since each wants a different buffer swapping behaviour.
318
31912th May 2006 John Allison (opengl-V08-00-06)
320- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
321
32228th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
323- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
324 recomputing transients.
325
32624th April 2006 John Allison (opengl-V08-00-04)
327- Fixed compilation problem on Windows.
328
32919th April 2006 John Allison (opengl-V08-00-03)
330- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
331 G4OpenGLImmediateSceneHandler:
332 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
333 greps-V08-00-02).
334 o Migrated to direct access to G4PhysicalVolumeModel.
335- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
336 of display lists in DrawView.
337
33814th March 2006 John Allison (opengl-V08-00-02)
339- Refined display list building and re-drawing algorithm.
340 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
341 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
342- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
343 re-use algorithm. In test19 with global culling off, numbers of
344 display lists used are:
345 o 191 No re-use:
346 o 73 Before this change: re-use except replicas (includes parameterised).
347 o 33 After this change: re-use except parameterised and replicas in radius.
348
34926th January 2006 John Allison (opengl-V08-00-01)
350- Coworks with visman-V08-00-04 (removed fModified).
351- Removed references to fModified.
352- Tidying: Removed unnecessary ClearView.
353- G4OpenGLSceneHandler.cc: Added some (commented out) code for
354 possible future implementation of 2D drawing.
355- G4OpenGLXViewer.cc: Improved exception printing.
356
35711th January 2006 John Allison (opengl-V08-00-00)
358- Improved efficiency: all DrawView's:
359 o Don't call ClearView.
360 o Set flag so SetView will not be called in ProcessView.
361 o Leave background colour to ClearView.
362- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
363- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
364 for current viewer.
365
36624th November 2005 John Allison (opengl-V07-01-09)
367- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
368
36922nd November 2005 John Allison (opengl-V07-01-08)
370- Added G4OpenGLXmViewerMessenger.
371- Corrected text position.
372- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
373
37417th November 2005 Gabriele Cosmo
375- Fixed settings of background style for WIN32 viewers.
376
37713th November 2005 John Allison (opengl-V07-01-07)
378- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
379
38013th October 2005 John Allison (opengl-V07-01-06)
381- Allowed any colour background.
382- Implemented non-uniform scaling.
383- Migration to <sstream>.
384
38529th September 2005 John Allison (opengl-V07-01-05)
386- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
387 scene handler.
388- Re-implemented transparency button in OpenGLXm.
389
39013th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
391- Implemented white background for all OGL viewers.
392- G4OpenGLSceneHandler.cc:
393 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
394 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
395 o Corrected GetTextColour(text).
396 o Corrected GetColour(polyhedron).
397
3985th September 2005 John Allison (opengl-V07-01-03)
399- Bug fix: stored transparent objects were being lost.
400
4012nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
402- Bug fix: edgeflags problem introduced with smooth shading in
403 opengl-V07-01-00.
404- Implementation of a "better algorithm" for the rendering of
405 transparent polyhedron objects. It renders all opaque objects
406 first, then renders the transparent objects with the depth buffer in
407 read-only mode (see OpenGL Programming Guide). It uses the new
408 facility in G4VSceneHandler::ProcessScene for an optional second pass
409 of the run-duration models in the scene. Note this algorithm is
410 still only an approximation. It will still give the wrong blended
411 colour if two transparent objects are rendered front first. For
412 nested transparent objects, this is unfortunate, because
413 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
414 in such a way that mothers come first. Also, there is no guaranteed
415 relationship between the order of rendering and the depth of two
416 transparent objects if they are at the same level or in different
417 branches of the hierarchy. Still, the only error will be an
418 incorrect colour - the objects will still give the appearance of
419 transparency, so it's a pretty good algorithm. (An even better
420 algorithm would be to attempt to render the facets in depth order,
421 deepest first. But how do you calculate the depth - centre of area,
422 deepest corner? One can still imagine pathalogical cases that would
423 sometimes give the wrong colour. Also, for stored mode, the order
424 is fixed in a display list so when the user rotates the view, one
425 would lose the depth ordering. I think we have to accept that
426 blending in OpenGL is only ever an approximation. For accurate
427 blending, use RayTracer.)
428
42928th August 2005 John Allison (opengl-V07-01-01)
430- Half-way implementation of rendering of transparent polyhedron
431 objects. In this implementation, no account is taken of the order
432 of rendering. Transparent objects are rendered with depth testing
433 off so that objects behind can still be seen. But this means that
434 opaque objects in front do not obscure them - and they jolly well
435 should! A better algorithm is to render all opaque objects first,
436 then render the transparent objects with the depth buffer in
437 read-only mode (see OpenGL Programming Guide). This is going to
438 take a little more thought - see opengl-V07-01-02.
439
44020th July 2005 John Allison (opengl-V07-01-00)
441- Introduced smooth shading, taking advantage of hitherto un-noticed
442 feature of HepPolyhedron::GetNextFacet that calculates the normals
443 at each vertex so that curved surfaces are rendered more
444 realistically (Gouraud shading).
445- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
446- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
447 the default window size. It used to be 400x400, hardcoded in
448 G4OpenGLXmViewer.cc, but now it picks up the
449 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
450 The user may change it on the command line, e.g:
451 /vis/open OGLSXm 500
452 or
453 /vis/viewer/create ! ! 500
454
45530th May 2005 John Allison (opengl-V07-00-03)
456- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
457 map of vectors in G4OpenGLFontBaseStore.)
458
4594th May 2005 John Allison (opengl-V07-00-02)
460- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
461 was taken out to prevent recursive calling, but that seems to be OK,
462 and it is needed to implement refresh at end of event/run.)
463
46422nd April 2005 John Allison (opengl-V07-00-01)
465- Rationalised work of opengl-V07-00-00. Functionality unchanged.
466 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
467 o In all concrete viewers, added call to CreateFontLists().
468 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
469 o There is no longer a need to implement in the XmViewer, since it
470 now inherits. Thus the font code now only appears once for X.
471 o Awaiting implementation for WIN32.
472
47317th April 2005 John Allison (opengl-V07-00-00)
474- Based on vis-V07-00-13.
475- Implemented text for X-Windows viewers. Uses glXUseXFont, which
476 creates display lists for nominated fonts. Simple-minded scheme in
477 which each viewer creates its own font display lists for a variety
478 of sizes, which are accessed by the scene handler through a new
479 class, G4OpenGLFontBaseStore. Affected methods:
480 G4OpenGLXViewer::CreateMainWindow()
481 G4OpenGLXmViewer::CreateMainWindow()
482 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
483
48418th November 2004 John Allison (opengl-V06-02-07)
485- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
486
48715th November 2004 Guy Barrand
488- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
489 to see trajectories (for example with N03). Correct so that
490 ShowView do a FinishView that does : glFlush, wglSwapBuffer
491 and empty the Windows message queue.
492
49322nd September 2004 John Allison (opengl-V06-02-06)
494- doxygen output to tmp area.
495- Trap non-regular polyhedrons.
496
49713th September 2004 Gabriele Cosmo (opengl-V06-02-05)
498- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
499 to allow for porting on CLHEP-1.9.X series.
500
50123rd July 2004 John Allison
502- Draws auxiliary edges if required.
503- Added auxiliary edge button.
504
50516th July 2004 John Allison (opengl-V06-02-04)
506- Refinements to hidden line, hidden surface removal.
507
50814th July 2004 John Allison (opengl-V06-02-03)
509- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
510
51113th July 2004 John Allison (opengl-V06-02-02)
512- Hidden line *and* hidden surface removal now works.
513
5149th July 2004 John Allison (opengl-V06-02-01)
515- Fixed long-standing problem with hidden line removal.
516- Improved messages on failure to get visual.
517- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
518 systems provided by default anyway, so no effect.
519
5201st July 2004 John Allison (opengl-V06-02-00)
521- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
522- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
523
52418th June 2004 Gunter Folger (geant4-06-02)
5259th June 2004 Gabriele Cosmo (vis-V06-01-03)
5267th June 2004 Gabriele Cosmo (vis-V06-01-02)
527- GNUmakefile and disclaimer changes - see visualization/History.
528
5299th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
530- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
531
5327th April 2004 Guy Barrand
533- visualization/OpenGL/* : use the G4OpenGL.hh file.
534- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
535 the include of gl/gl.h and gl/glu.h that may be platform dependant.
536 It permits to rm some #ifdef WIN32 spread in the code. It opens also
537 the way to the usage of the Apple OpenGL on a Mac.
538
53917th February 2004 John Allison (opengl-V06-00-00)
540- Fixed bug #581: wrong order of statements in
541 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
542
5434th October 2003 Gabriele Cosmo (vis-V05-02-01)
544- GNUmakefile:
545 o replaced "digits+hits" with "digits_hits".
546- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
547
54822nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
549- Cosmetic change to regularise names:
550 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
551 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
552
55323rd June 2003 Guy Barrand (opengl-V05-01-02)
554- Commit a first implementation of G4OpenGLWin32Viewer.
555
55610th June 2003 Gabriele Cosmo (opengl-V05-01-01)
557- More fixes for warnings in viewers classes.
558- Added inclusion of <windows.h> for WIN32 platforms when GL headers
559 are included.
560
56105th June 2003 Gabriele Cosmo (opengl-V05-01-00)
562- Fixes for porting compilation on WIN32:
563 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
564 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
565 since declared 'obsolete' in WIN32 platforms.
566
56727th November 2002 John Allison (vis-V04-01-08)
568- Improved algorithm of CompareForKernelVisit.
569
57011th November 2002 John Allison (opengl-V04-01-02)
571- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
572- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
573 call default but there as a marker and encourager.
574- Added tracking and digits+hits/hits to GNUmakefile.
575
57616th October 2002 John Allison (opengl-V04-01-01)
577- Fix for WIN32. Now compiles but viewer not implemented.
578
57924th June 2002 John Allison (opengl-V04-01-00)
580- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
581
58210th June 2002 John Allison (opengl-V04-00-03)
583- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
584
5856th June 2002 John Allison (opengl-V04-00-02)
586- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
587
58823rd February 2002 John Allison (opengl-V04-00-01)
589- Changes to encourage compilation on Windows in preparation for
590 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
591 glx.h, unistd.h and assert.h.
592
59324th August 2001 John Allison (vis-V03-02-13)
594- Limited the printing of warnings in
595 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
596
59714th August 2001 John Allison (vis-V03-02-11)
598- Improved KernelVisitDecision.
599- Fixed a few small bugs in multiple "stored" viewers, but see next item.
600- There's an outstanding bug in OpenGL Stored. If there is more than
601 one viewer controlled by a scene handler, after a ClearStore on the
602 scene handler, e.g., with /vis/scene/notifyHandlers, the first
603 viewer to get refreshed should trigger the display list rebuild, but
604 the second need not. However, when the second viewer's turn comes,
605 the display lists are there, and are called, e.g.,
606 G4OpenGLStoredXViewer::DrawView calls
607 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
608 nothing appears on the screen. To overcome this there is some
609 temporary code in G4VViewer::NeedKernelVisit which marks *all*
610 viewers to force a rebuild. To see the symptoms, comment out that
611 temporary code and issue these commands:
612 /vis/verbose c
613 /control/verbose 2
614 /vis/scene/create
615 /vis/scene/add/volume
616 /vis/sceneHandler/create OGLSX
617 /vis/viewer/create ! ! 1
618 /run/beamOn
619 /vis/viewer/create ! ! 1
620 /vis/viewer/select viewer-0
621 /vis/viewer/viewpointThetaPhi 20 20
622 /vis/viewer/select viewer-1
623 /vis/viewer/viewpointThetaPhi 40 40
624 /vis/viewer/set/style surface
625 /vis/viewer/refresh
626 /vis/viewer/select viewer-0
627 /vis/viewer/refresh
628 /vis/viewer/select viewer-1
629 /vis/viewer/set/style wireframe
630 /vis/scene/notifyHandlers
631 You may have to do this too:
632 /vis/viewer/select viewer-0
633 /vis/scene/notifyHandlers
634 One of the viewers is empty. Curious!!
635
6369th August 2001 John Allison (vis-V03-02-10-00)
637- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
638- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
639 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
640 picked up by inheritance anyway.
641- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
642- Corrected order of calling base class functions in
643 G4OpenGLStoredSceneHandler::Begin/EndModeling.
644
64524th July 2001 John Allison (vis-V03-02-06)
646- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
647
64814th July 2001 John Allison (opengl-V03-02-00)
649- Fixed crash in optimised mode: added Initialise() to viewers so
650 that windows are opened after viewers are fully constructed.
651
6522nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
653- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
654
6557th March 2001 John Allison
656- Changed char* to const char* in many places and that gave problems in
657 calls to Xt and Xm. Hope all's OK. Differences:
658 cvs diff -r vis-V03-00-06 vis-V03-00-07
659
66025th January 2001 John Allison (opengl-V03-00-00)
661- Implemented running re-calculation of up-vector in the case of "object
662 rotation" (lights move with camera) to prevent "flipping" of view when
663 camera passes through up-vector. Note that the default is "camera
664 rotation" (lights do not move with camera, i.e., remain fixed relative
665 to object) so the default is that this "flipping" can happen. To set
666 "object rotation" (lights move with camera) use
667 /vis/lights/move_with_camera true (soon to be
668 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
669 on Rotation Panel in OpenGLXm mode.
670- Changed some objects to references for efficiency. E.g.:
671 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
672
67322nd May 2000 John Allison (opengl-V01-01-00)
674- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
675 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
676 static XVisualInfo* vi_single_buffer;
677 static XVisualInfo* vi_double_buffer;
678- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
679 G4OpenGLXViewer.
680- Protected double deletion of window in destructors of G4OpenGLXmViewer
681 and G4OpenGLXViewer (Guy Barrand).
682- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
683- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
684 constructors.
Note: See TracBrowser for help on using the repository browser.
