198 and "/vis/ogl/printEPS").
199
2008th May 2007 John Allison (opengl-V08-02-06)
201- Moved vectored PostScript printing to G4OpenGLViewer.
202- /vis/ogl/printEPS should work for all viewers, including Win32.
203- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
204 effective on X windows (and still somewhat buggy).
205
2064th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
207- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
208 for OGL*Win32. Still doesn't work for OGL*Xm.
209
2103rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
211- G4OpenGLStoredSceneHandler:
212 o Re-organised display lists on a per-primitive basis, i.e., one
213 display list per primitive. (This is so that, except for text,
214 the colour - or, rather, intensity - can be brought out of the
215 display list into the TOList (Transient Object List) and
216 controlled for the Display-by-Time feature. Previously, if more
217 than one primitive were drawn between BeginPrimitives and
218 EndPrimitives, it would finish up all in one display list, colour
219 commands included. Rationalises and fixes a rare bug in the
220 Display-by-Time feature - see August 2006.)
221 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
222 one primoitive to fit with the above re-organisation.
223- Implemented picking for OGLIX.
224
22525th March 2007 John Allison (opengl-V08-02-03)
226- Fix compiler warnings.
227
2288th February 2007 John Allison (opengl-V08-02-02)
229- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
230- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
231 .but not switched back. Not serious, because context was always set
232 before normal drawing.)
233
2349th January 2007 John Allison (opengl-V08-02-01)
235- Implemented bitmap markers for MarkerSizeType == screen. (The old
236 polygon implementation remains for MarkerSizeType == world.)
237- Added G4OpenGLBitMapStore to assist the above.
238- G4OpenGLXViewer::CreateGLXContext:
239 o Bug fix: Added missing break in colormap lookup routine.
240
2415th January 2007 John Allison (opengl-V08-02-00)
242- G4OpenGLSceneHandler.cc:
243 o Followed change of signature of GetLineWidth in visman-V08-02-00.
244 o Minor efficiency improvements.
245
24621st November 2006 John Allison (opengl-V08-01-09)
247- Fixed compiler warnings.
248
2491st November 2006 John Allison (opengl-V08-01-08)
250- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
251 actually initiates a print, rather than set a flag for printing.
252
25324th October 2006 John Allison (opengl-V08-01-07)
254- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
255- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
256
25719th September 2006 John Allison (opengl-V08-01-06)

259- Added /vis/ogl/set/transparency.
260- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
261
2624th September 2006 John Allison (opengl-V08-01-05)
263- Implement cutaways.
264- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
265 primitives (see detector being drawn).
266- /vis/oglx/set/printEPS: change parameter default to true.
267
26830th August 2006 John Allison (opengl-V08-01-04)
269- G4OpenGLSceneHandler:
270 o Implemented line width.
271 o Switched off back face culling when clipping so that the inside of
272 volumes can be seen.
273 o Added CreateSection/CutawayPolyhedron to exploit generic
274 sectioning (DCUT) and cutaways. Currently not activated due to
275 instabilities in BooleanProcessor. Local sectioning still active
276 but broken (at least on Mac) due to apparent change in effect of
277 clipping planes (polyhedron edges not reconstructed).
278 o Rationalised calculation of marker size.
279- G4OpenGLStoredSceneHandler:
280 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
281 o Pick up time range from G4VisAttributes.
282- G4OpenGLViewer(Messenger):
283 o Added position and colour to /vis/ogl/set/displayHeadTime.
284 o Added /vis/ogl/set/displayLightFront.
285- G4OpenGLStoredViewer.cc:
286 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
287 o Added position and colour to DisplayHeadTime.
288 o Added DisplayLightFront.
289
29016th August 2006 John Allison (opengl-V08-01-03)
291- Corrected Solaris compilation error.
292- Added /vis/ogl/set/fade and displayHeadTime.
293
29414th August 2006 John Allison (opengl-V08-01-02)
295- Needs visman-V08-01-02.
296- G4OpenGLStored: Implemented display-by-time. Only available in
297 stored mode at present. Only implemented for circle, square,
298 polyline and polymarker at present, enough for currently available
299 trajectory models. Time is communicated via G4AttValues.
300- Added G4OpenGLViewerMessenger.
301- Added /vis/ogl/set/startTime and endTime of displayed objects.
302- All factories: Instantiated G4OpenGLViewerMessenger.
303- G4OpenGLViewer: Added fStart/EndTime.
304- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
305 spewPrimitiveEPS and spewSortedFeedback.
306
30717th July John Allison (opengl-V08-01-01)
308- Added /vis/oglx/set/printEPS (prints eps file on every update).
309
3103rd July 2006 John Allison (opengl-V08-01-00)
311- Elimination of redundant variable doublebuffer and implementation of
312 FinishView in all viewers.
313
31430th May 2006 Joseph Perl (opengl-V08-00-08)
315- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
316 variable seems to have random behavior and should be assumed false for
317 this viewer.
318
31929th May 2006 Joseph Perl (opengl-V08-00-07)
320- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
321 Removed common FinishView and instead made separate FinishView for the two different
322 versions of this viewer since each wants a different buffer swapping behaviour.
323
32412th May 2006 John Allison (opengl-V08-00-06)
325- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
326
32728th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
328- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
329 recomputing transients.
330
33124th April 2006 John Allison (opengl-V08-00-04)
332- Fixed compilation problem on Windows.
333
33419th April 2006 John Allison (opengl-V08-00-03)
335- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
336 G4OpenGLImmediateSceneHandler:
337 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
338 greps-V08-00-02).
339 o Migrated to direct access to G4PhysicalVolumeModel.
340- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
341 of display lists in DrawView.
342
34314th March 2006 John Allison (opengl-V08-00-02)
344- Refined display list building and re-drawing algorithm.
345 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
346 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
347- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
348 re-use algorithm. In test19 with global culling off, numbers of
349 display lists used are:
350 o 191 No re-use:
351 o 73 Before this change: re-use except replicas (includes parameterised).
352 o 33 After this change: re-use except parameterised and replicas in radius.
353
35426th January 2006 John Allison (opengl-V08-00-01)
355- Coworks with visman-V08-00-04 (removed fModified).
356- Removed references to fModified.
357- Tidying: Removed unnecessary ClearView.
358- G4OpenGLSceneHandler.cc: Added some (commented out) code for
359 possible future implementation of 2D drawing.
360- G4OpenGLXViewer.cc: Improved exception printing.
361
36211th January 2006 John Allison (opengl-V08-00-00)
363- Improved efficiency: all DrawView's:
364 o Don't call ClearView.
365 o Set flag so SetView will not be called in ProcessView.
366 o Leave background colour to ClearView.
367- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
368- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
369 for current viewer.
370
37124th November 2005 John Allison (opengl-V07-01-09)
372- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
373
37422nd November 2005 John Allison (opengl-V07-01-08)
375- Added G4OpenGLXmViewerMessenger.
376- Corrected text position.
377- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
378
37917th November 2005 Gabriele Cosmo
380- Fixed settings of background style for WIN32 viewers.
381
38213th November 2005 John Allison (opengl-V07-01-07)
383- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
384
38513th October 2005 John Allison (opengl-V07-01-06)
386- Allowed any colour background.
387- Implemented non-uniform scaling.
388- Migration to <sstream>.
389
39029th September 2005 John Allison (opengl-V07-01-05)
391- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
392 scene handler.
393- Re-implemented transparency button in OpenGLXm.
394
39513th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
396- Implemented white background for all OGL viewers.
397- G4OpenGLSceneHandler.cc:
398 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
399 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
400 o Corrected GetTextColour(text).
401 o Corrected GetColour(polyhedron).
402
4035th September 2005 John Allison (opengl-V07-01-03)
404- Bug fix: stored transparent objects were being lost.
405
4062nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
407- Bug fix: edgeflags problem introduced with smooth shading in
408 opengl-V07-01-00.
409- Implementation of a "better algorithm" for the rendering of
410 transparent polyhedron objects. It renders all opaque objects
411 first, then renders the transparent objects with the depth buffer in
412 read-only mode (see OpenGL Programming Guide). It uses the new
413 facility in G4VSceneHandler::ProcessScene for an optional second pass
414 of the run-duration models in the scene. Note this algorithm is
415 still only an approximation. It will still give the wrong blended
416 colour if two transparent objects are rendered front first. For
417 nested transparent objects, this is unfortunate, because
418 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
419 in such a way that mothers come first. Also, there is no guaranteed
420 relationship between the order of rendering and the depth of two
421 transparent objects if they are at the same level or in different
422 branches of the hierarchy. Still, the only error will be an
423 incorrect colour - the objects will still give the appearance of
424 transparency, so it's a pretty good algorithm. (An even better
425 algorithm would be to attempt to render the facets in depth order,
426 deepest first. But how do you calculate the depth - centre of area,
427 deepest corner? One can still imagine pathalogical cases that would
428 sometimes give the wrong colour. Also, for stored mode, the order
429 is fixed in a display list so when the user rotates the view, one
430 would lose the depth ordering. I think we have to accept that
431 blending in OpenGL is only ever an approximation. For accurate
432 blending, use RayTracer.)
433
43428th August 2005 John Allison (opengl-V07-01-01)
435- Half-way implementation of rendering of transparent polyhedron
436 objects. In this implementation, no account is taken of the order
437 of rendering. Transparent objects are rendered with depth testing
438 off so that objects behind can still be seen. But this means that
439 opaque objects in front do not obscure them - and they jolly well
440 should! A better algorithm is to render all opaque objects first,
441 then render the transparent objects with the depth buffer in
442 read-only mode (see OpenGL Programming Guide). This is going to
443 take a little more thought - see opengl-V07-01-02.
444
44520th July 2005 John Allison (opengl-V07-01-00)
446- Introduced smooth shading, taking advantage of hitherto un-noticed
447 feature of HepPolyhedron::GetNextFacet that calculates the normals
448 at each vertex so that curved surfaces are rendered more
449 realistically (Gouraud shading).
450- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
451- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
452 the default window size. It used to be 400x400, hardcoded in
453 G4OpenGLXmViewer.cc, but now it picks up the
454 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
455 The user may change it on the command line, e.g:
456 /vis/open OGLSXm 500
457 or
458 /vis/viewer/create ! ! 500
459
46030th May 2005 John Allison (opengl-V07-00-03)
461- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
462 map of vectors in G4OpenGLFontBaseStore.)
463
4644th May 2005 John Allison (opengl-V07-00-02)
465- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
466 was taken out to prevent recursive calling, but that seems to be OK,
467 and it is needed to implement refresh at end of event/run.)
468
46922nd April 2005 John Allison (opengl-V07-00-01)
470- Rationalised work of opengl-V07-00-00. Functionality unchanged.
471 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
472 o In all concrete viewers, added call to CreateFontLists().
473 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
474 o There is no longer a need to implement in the XmViewer, since it
475 now inherits. Thus the font code now only appears once for X.
476 o Awaiting implementation for WIN32.
477
47817th April 2005 John Allison (opengl-V07-00-00)
479- Based on vis-V07-00-13.
480- Implemented text for X-Windows viewers. Uses glXUseXFont, which
481 creates display lists for nominated fonts. Simple-minded scheme in
482 which each viewer creates its own font display lists for a variety
483 of sizes, which are accessed by the scene handler through a new
484 class, G4OpenGLFontBaseStore. Affected methods:
485 G4OpenGLXViewer::CreateMainWindow()
486 G4OpenGLXmViewer::CreateMainWindow()
487 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
488
48918th November 2004 John Allison (opengl-V06-02-07)
490- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
491
49215th November 2004 Guy Barrand
493- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
494 to see trajectories (for example with N03). Correct so that
495 ShowView do a FinishView that does : glFlush, wglSwapBuffer
496 and empty the Windows message queue.
497
49822nd September 2004 John Allison (opengl-V06-02-06)
499- doxygen output to tmp area.
500- Trap non-regular polyhedrons.
501
50213th September 2004 Gabriele Cosmo (opengl-V06-02-05)
503- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
504 to allow for porting on CLHEP-1.9.X series.
505
50623rd July 2004 John Allison
507- Draws auxiliary edges if required.
508- Added auxiliary edge button.
509
51016th July 2004 John Allison (opengl-V06-02-04)
511- Refinements to hidden line, hidden surface removal.
512
51314th July 2004 John Allison (opengl-V06-02-03)
514- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
515
51613th July 2004 John Allison (opengl-V06-02-02)
517- Hidden line *and* hidden surface removal now works.
518
5199th July 2004 John Allison (opengl-V06-02-01)
520- Fixed long-standing problem with hidden line removal.
521- Improved messages on failure to get visual.
522- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
523 systems provided by default anyway, so no effect.
524
5251st July 2004 John Allison (opengl-V06-02-00)
526- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
527- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
528
52918th June 2004 Gunter Folger (geant4-06-02)
5309th June 2004 Gabriele Cosmo (vis-V06-01-03)
5317th June 2004 Gabriele Cosmo (vis-V06-01-02)
532- GNUmakefile and disclaimer changes - see visualization/History.
533
5349th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
535- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
536
5377th April 2004 Guy Barrand
538- visualization/OpenGL/* : use the G4OpenGL.hh file.
539- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
540 the include of gl/gl.h and gl/glu.h that may be platform dependant.
541 It permits to rm some #ifdef WIN32 spread in the code. It opens also
542 the way to the usage of the Apple OpenGL on a Mac.
543
54417th February 2004 John Allison (opengl-V06-00-00)
545- Fixed bug #581: wrong order of statements in
546 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
547
5484th October 2003 Gabriele Cosmo (vis-V05-02-01)
549- GNUmakefile:
550 o replaced "digits+hits" with "digits_hits".
551- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
552
55322nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
554- Cosmetic change to regularise names:
555 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
556 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
557
55823rd June 2003 Guy Barrand (opengl-V05-01-02)
559- Commit a first implementation of G4OpenGLWin32Viewer.
560
56110th June 2003 Gabriele Cosmo (opengl-V05-01-01)
562- More fixes for warnings in viewers classes.
563- Added inclusion of <windows.h> for WIN32 platforms when GL headers
564 are included.
565
56605th June 2003 Gabriele Cosmo (opengl-V05-01-00)
567- Fixes for porting compilation on WIN32:
568 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
569 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
570 since declared 'obsolete' in WIN32 platforms.
571
57227th November 2002 John Allison (vis-V04-01-08)
573- Improved algorithm of CompareForKernelVisit.
574
57511th November 2002 John Allison (opengl-V04-01-02)
576- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
577- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
578 call default but there as a marker and encourager.
579- Added tracking and digits+hits/hits to GNUmakefile.
580
58116th October 2002 John Allison (opengl-V04-01-01)
582- Fix for WIN32. Now compiles but viewer not implemented.
583
58424th June 2002 John Allison (opengl-V04-01-00)
585- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
586
58710th June 2002 John Allison (opengl-V04-00-03)
588- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
589
5906th June 2002 John Allison (opengl-V04-00-02)
591- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
592
59323rd February 2002 John Allison (opengl-V04-00-01)
594- Changes to encourage compilation on Windows in preparation for
595 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
596 glx.h, unistd.h and assert.h.
597
59824th August 2001 John Allison (vis-V03-02-13)
599- Limited the printing of warnings in
600 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
601
60214th August 2001 John Allison (vis-V03-02-11)
603- Improved KernelVisitDecision.
604- Fixed a few small bugs in multiple "stored" viewers, but see next item.
605- There's an outstanding bug in OpenGL Stored. If there is more than
606 one viewer controlled by a scene handler, after a ClearStore on the
607 scene handler, e.g., with /vis/scene/notifyHandlers, the first
608 viewer to get refreshed should trigger the display list rebuild, but
609 the second need not. However, when the second viewer's turn comes,
610 the display lists are there, and are called, e.g.,
611 G4OpenGLStoredXViewer::DrawView calls
612 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
613 nothing appears on the screen. To overcome this there is some
614 temporary code in G4VViewer::NeedKernelVisit which marks *all*
615 viewers to force a rebuild. To see the symptoms, comment out that
616 temporary code and issue these commands:
617 /vis/verbose c
618 /control/verbose 2
619 /vis/scene/create
620 /vis/scene/add/volume
621 /vis/sceneHandler/create OGLSX
622 /vis/viewer/create ! ! 1
623 /run/beamOn
624 /vis/viewer/create ! ! 1
625 /vis/viewer/select viewer-0
626 /vis/viewer/viewpointThetaPhi 20 20
627 /vis/viewer/select viewer-1
628 /vis/viewer/viewpointThetaPhi 40 40
629 /vis/viewer/set/style surface
630 /vis/viewer/refresh
631 /vis/viewer/select viewer-0
632 /vis/viewer/refresh
633 /vis/viewer/select viewer-1
634 /vis/viewer/set/style wireframe
635 /vis/scene/notifyHandlers
636 You may have to do this too:
637 /vis/viewer/select viewer-0
638 /vis/scene/notifyHandlers
639 One of the viewers is empty. Curious!!
640
6419th August 2001 John Allison (vis-V03-02-10-00)
642- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
643- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
644 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
645 picked up by inheritance anyway.
646- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
647- Corrected order of calling base class functions in
648 G4OpenGLStoredSceneHandler::Begin/EndModeling.
649
65024th July 2001 John Allison (vis-V03-02-06)
651- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
652
65314th July 2001 John Allison (opengl-V03-02-00)
654- Fixed crash in optimised mode: added Initialise() to viewers so
655 that windows are opened after viewers are fully constructed.
656
6572nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
658- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
659
6607th March 2001 John Allison
661- Changed char* to const char* in many places and that gave problems in
662 calls to Xt and Xm. Hope all's OK. Differences:
663 cvs diff -r vis-V03-00-06 vis-V03-00-07
664
66525th January 2001 John Allison (opengl-V03-00-00)
666- Implemented running re-calculation of up-vector in the case of "object
667 rotation" (lights move with camera) to prevent "flipping" of view when
668 camera passes through up-vector. Note that the default is "camera
669 rotation" (lights do not move with camera, i.e., remain fixed relative
670 to object) so the default is that this "flipping" can happen. To set
671 "object rotation" (lights move with camera) use
672 /vis/lights/move_with_camera true (soon to be
673 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
674 on Rotation Panel in OpenGLXm mode.
675- Changed some objects to references for efficiency. E.g.:
676 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
677
67822nd May 2000 John Allison (opengl-V01-01-00)
679- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
680 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
681 static XVisualInfo* vi_single_buffer;
682 static XVisualInfo* vi_double_buffer;
683- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
684 G4OpenGLXViewer.
685- Protected double deletion of window in destructors of G4OpenGLXmViewer
686 and G4OpenGLXViewer (Guy Barrand).
687- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
688- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
689 constructors.
