321
32225th May 2007 John Allison (opengl-V08-03-03)

337 and "/vis/ogl/printEPS").
338
3398th May 2007 John Allison (opengl-V08-02-06)
340- Moved vectored PostScript printing to G4OpenGLViewer.
341- /vis/ogl/printEPS should work for all viewers, including Win32.
342- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
343 effective on X windows (and still somewhat buggy).
344
3454th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
346- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
347 for OGL*Win32. Still doesn't work for OGL*Xm.
348
3493rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
350- G4OpenGLStoredSceneHandler:
351 o Re-organised display lists on a per-primitive basis, i.e., one
352 display list per primitive. (This is so that, except for text,
353 the colour - or, rather, intensity - can be brought out of the
354 display list into the TOList (Transient Object List) and
355 controlled for the Display-by-Time feature. Previously, if more
356 than one primitive were drawn between BeginPrimitives and
357 EndPrimitives, it would finish up all in one display list, colour
358 commands included. Rationalises and fixes a rare bug in the
359 Display-by-Time feature - see August 2006.)
360 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
361 one primoitive to fit with the above re-organisation.
362- Implemented picking for OGLIX.
363
36425th March 2007 John Allison (opengl-V08-02-03)
365- Fix compiler warnings.
366
3678th February 2007 John Allison (opengl-V08-02-02)
368- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
369- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
370 .but not switched back. Not serious, because context was always set
371 before normal drawing.)
372
3739th January 2007 John Allison (opengl-V08-02-01)
374- Implemented bitmap markers for MarkerSizeType == screen. (The old
375 polygon implementation remains for MarkerSizeType == world.)
376- Added G4OpenGLBitMapStore to assist the above.
377- G4OpenGLXViewer::CreateGLXContext:
378 o Bug fix: Added missing break in colormap lookup routine.
379
3805th January 2007 John Allison (opengl-V08-02-00)
381- G4OpenGLSceneHandler.cc:
382 o Followed change of signature of GetLineWidth in visman-V08-02-00.
383 o Minor efficiency improvements.
384
38521st November 2006 John Allison (opengl-V08-01-09)
386- Fixed compiler warnings.
387
3881st November 2006 John Allison (opengl-V08-01-08)
389- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
390 actually initiates a print, rather than set a flag for printing.
391
39224th October 2006 John Allison (opengl-V08-01-07)
393- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
394- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
395
39619th September 2006 John Allison (opengl-V08-01-06)

400
4014th September 2006 John Allison (opengl-V08-01-05)
402- Implement cutaways.
403- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
404 primitives (see detector being drawn).
405- /vis/oglx/set/printEPS: change parameter default to true.
406
40730th August 2006 John Allison (opengl-V08-01-04)
408- G4OpenGLSceneHandler:
409 o Implemented line width.
410 o Switched off back face culling when clipping so that the inside of
411 volumes can be seen.
412 o Added CreateSection/CutawayPolyhedron to exploit generic
413 sectioning (DCUT) and cutaways. Currently not activated due to
414 instabilities in BooleanProcessor. Local sectioning still active
415 but broken (at least on Mac) due to apparent change in effect of
416 clipping planes (polyhedron edges not reconstructed).
417 o Rationalised calculation of marker size.
418- G4OpenGLStoredSceneHandler:
419 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
420 o Pick up time range from G4VisAttributes.
421- G4OpenGLViewer(Messenger):
422 o Added position and colour to /vis/ogl/set/displayHeadTime.
423 o Added /vis/ogl/set/displayLightFront.
424- G4OpenGLStoredViewer.cc:
425 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
426 o Added position and colour to DisplayHeadTime.
427 o Added DisplayLightFront.
428
42916th August 2006 John Allison (opengl-V08-01-03)
430- Corrected Solaris compilation error.
431- Added /vis/ogl/set/fade and displayHeadTime.
432
43314th August 2006 John Allison (opengl-V08-01-02)
434- Needs visman-V08-01-02.
435- G4OpenGLStored: Implemented display-by-time. Only available in
436 stored mode at present. Only implemented for circle, square,
437 polyline and polymarker at present, enough for currently available
438 trajectory models. Time is communicated via G4AttValues.
439- Added G4OpenGLViewerMessenger.
440- Added /vis/ogl/set/startTime and endTime of displayed objects.
441- All factories: Instantiated G4OpenGLViewerMessenger.
442- G4OpenGLViewer: Added fStart/EndTime.
443- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
444 spewPrimitiveEPS and spewSortedFeedback.
445
44617th July John Allison (opengl-V08-01-01)
447- Added /vis/oglx/set/printEPS (prints eps file on every update).
448
4493rd July 2006 John Allison (opengl-V08-01-00)
450- Elimination of redundant variable doublebuffer and implementation of
451 FinishView in all viewers.
452
45330th May 2006 Joseph Perl (opengl-V08-00-08)
454- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
455 variable seems to have random behavior and should be assumed false for
456 this viewer.
457
45829th May 2006 Joseph Perl (opengl-V08-00-07)
459- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
460 Removed common FinishView and instead made separate FinishView for the two different
461 versions of this viewer since each wants a different buffer swapping behaviour.
462
46312th May 2006 John Allison (opengl-V08-00-06)
464- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
465
46628th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
467- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
468 recomputing transients.
469
47024th April 2006 John Allison (opengl-V08-00-04)
471- Fixed compilation problem on Windows.
472
47319th April 2006 John Allison (opengl-V08-00-03)
474- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
475 G4OpenGLImmediateSceneHandler:
476 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
477 greps-V08-00-02).
478 o Migrated to direct access to G4PhysicalVolumeModel.
479- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
480 of display lists in DrawView.
481
48214th March 2006 John Allison (opengl-V08-00-02)
483- Refined display list building and re-drawing algorithm.
484 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
485 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
486- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
487 re-use algorithm. In test19 with global culling off, numbers of
488 display lists used are:
489 o 191 No re-use:
490 o 73 Before this change: re-use except replicas (includes parameterised).
491 o 33 After this change: re-use except parameterised and replicas in radius.
492
49326th January 2006 John Allison (opengl-V08-00-01)
494- Coworks with visman-V08-00-04 (removed fModified).
495- Removed references to fModified.
496- Tidying: Removed unnecessary ClearView.
497- G4OpenGLSceneHandler.cc: Added some (commented out) code for
498 possible future implementation of 2D drawing.
499- G4OpenGLXViewer.cc: Improved exception printing.
500
50111th January 2006 John Allison (opengl-V08-00-00)
502- Improved efficiency: all DrawView's:
503 o Don't call ClearView.
504 o Set flag so SetView will not be called in ProcessView.
505 o Leave background colour to ClearView.
506- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
507- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
508 for current viewer.
509
51024th November 2005 John Allison (opengl-V07-01-09)
511- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
512
51322nd November 2005 John Allison (opengl-V07-01-08)
514- Added G4OpenGLXmViewerMessenger.
515- Corrected text position.
516- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
517
51817th November 2005 Gabriele Cosmo
519- Fixed settings of background style for WIN32 viewers.
520
52113th November 2005 John Allison (opengl-V07-01-07)
522- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
523
52413th October 2005 John Allison (opengl-V07-01-06)
525- Allowed any colour background.
526- Implemented non-uniform scaling.
527- Migration to <sstream>.
528
52929th September 2005 John Allison (opengl-V07-01-05)
530- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
531 scene handler.
532- Re-implemented transparency button in OpenGLXm.
533
53413th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
535- Implemented white background for all OGL viewers.
536- G4OpenGLSceneHandler.cc:
537 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
538 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
539 o Corrected GetTextColour(text).
540 o Corrected GetColour(polyhedron).
541
5425th September 2005 John Allison (opengl-V07-01-03)
543- Bug fix: stored transparent objects were being lost.
544
5452nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
546- Bug fix: edgeflags problem introduced with smooth shading in
547 opengl-V07-01-00.
548- Implementation of a "better algorithm" for the rendering of
549 transparent polyhedron objects. It renders all opaque objects
550 first, then renders the transparent objects with the depth buffer in
551 read-only mode (see OpenGL Programming Guide). It uses the new
552 facility in G4VSceneHandler::ProcessScene for an optional second pass
553 of the run-duration models in the scene. Note this algorithm is
554 still only an approximation. It will still give the wrong blended
555 colour if two transparent objects are rendered front first. For
556 nested transparent objects, this is unfortunate, because
557 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
558 in such a way that mothers come first. Also, there is no guaranteed
559 relationship between the order of rendering and the depth of two
560 transparent objects if they are at the same level or in different
561 branches of the hierarchy. Still, the only error will be an
562 incorrect colour - the objects will still give the appearance of
563 transparency, so it's a pretty good algorithm. (An even better
564 algorithm would be to attempt to render the facets in depth order,
565 deepest first. But how do you calculate the depth - centre of area,
566 deepest corner? One can still imagine pathalogical cases that would
567 sometimes give the wrong colour. Also, for stored mode, the order
568 is fixed in a display list so when the user rotates the view, one
569 would lose the depth ordering. I think we have to accept that
570 blending in OpenGL is only ever an approximation. For accurate
571 blending, use RayTracer.)
572
57328th August 2005 John Allison (opengl-V07-01-01)
574- Half-way implementation of rendering of transparent polyhedron
575 objects. In this implementation, no account is taken of the order
576 of rendering. Transparent objects are rendered with depth testing
577 off so that objects behind can still be seen. But this means that
578 opaque objects in front do not obscure them - and they jolly well
579 should! A better algorithm is to render all opaque objects first,
580 then render the transparent objects with the depth buffer in
581 read-only mode (see OpenGL Programming Guide). This is going to
582 take a little more thought - see opengl-V07-01-02.
583
58420th July 2005 John Allison (opengl-V07-01-00)
585- Introduced smooth shading, taking advantage of hitherto un-noticed
586 feature of HepPolyhedron::GetNextFacet that calculates the normals
587 at each vertex so that curved surfaces are rendered more
588 realistically (Gouraud shading).
589- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
590- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
591 the default window size. It used to be 400x400, hardcoded in
592 G4OpenGLXmViewer.cc, but now it picks up the
593 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
594 The user may change it on the command line, e.g:
595 /vis/open OGLSXm 500
596 or
597 /vis/viewer/create ! ! 500
598
59930th May 2005 John Allison (opengl-V07-00-03)
600- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
601 map of vectors in G4OpenGLFontBaseStore.)
602
6034th May 2005 John Allison (opengl-V07-00-02)
604- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
605 was taken out to prevent recursive calling, but that seems to be OK,
606 and it is needed to implement refresh at end of event/run.)
607
60822nd April 2005 John Allison (opengl-V07-00-01)
609- Rationalised work of opengl-V07-00-00. Functionality unchanged.
610 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
611 o In all concrete viewers, added call to CreateFontLists().
612 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
613 o There is no longer a need to implement in the XmViewer, since it
614 now inherits. Thus the font code now only appears once for X.
615 o Awaiting implementation for WIN32.
616
61717th April 2005 John Allison (opengl-V07-00-00)
618- Based on vis-V07-00-13.
619- Implemented text for X-Windows viewers. Uses glXUseXFont, which
620 creates display lists for nominated fonts. Simple-minded scheme in
621 which each viewer creates its own font display lists for a variety
622 of sizes, which are accessed by the scene handler through a new
623 class, G4OpenGLFontBaseStore. Affected methods:
624 G4OpenGLXViewer::CreateMainWindow()
625 G4OpenGLXmViewer::CreateMainWindow()
626 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
627
62818th November 2004 John Allison (opengl-V06-02-07)
629- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
630
63115th November 2004 Guy Barrand
632- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
633 to see trajectories (for example with N03). Correct so that
634 ShowView do a FinishView that does : glFlush, wglSwapBuffer
635 and empty the Windows message queue.
636
63722nd September 2004 John Allison (opengl-V06-02-06)
638- doxygen output to tmp area.
639- Trap non-regular polyhedrons.
640
64113th September 2004 Gabriele Cosmo (opengl-V06-02-05)
642- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
643 to allow for porting on CLHEP-1.9.X series.
644
64523rd July 2004 John Allison
646- Draws auxiliary edges if required.
647- Added auxiliary edge button.
648
64916th July 2004 John Allison (opengl-V06-02-04)
650- Refinements to hidden line, hidden surface removal.
651
65214th July 2004 John Allison (opengl-V06-02-03)
653- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
654
65513th July 2004 John Allison (opengl-V06-02-02)
656- Hidden line *and* hidden surface removal now works.
657
6589th July 2004 John Allison (opengl-V06-02-01)
659- Fixed long-standing problem with hidden line removal.
660- Improved messages on failure to get visual.
661- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
662 systems provided by default anyway, so no effect.
663
6641st July 2004 John Allison (opengl-V06-02-00)
665- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
666- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
667
66818th June 2004 Gunter Folger (geant4-06-02)
6699th June 2004 Gabriele Cosmo (vis-V06-01-03)
6707th June 2004 Gabriele Cosmo (vis-V06-01-02)
671- GNUmakefile and disclaimer changes - see visualization/History.
672
6739th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
674- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
675
6767th April 2004 Guy Barrand
677- visualization/OpenGL/* : use the G4OpenGL.hh file.
678- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
679 the include of gl/gl.h and gl/glu.h that may be platform dependant.
680 It permits to rm some #ifdef WIN32 spread in the code. It opens also
681 the way to the usage of the Apple OpenGL on a Mac.
682
68317th February 2004 John Allison (opengl-V06-00-00)
684- Fixed bug #581: wrong order of statements in
685 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
686
6874th October 2003 Gabriele Cosmo (vis-V05-02-01)
688- GNUmakefile:
689 o replaced "digits+hits" with "digits_hits".
690- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
691
69222nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
693- Cosmetic change to regularise names:
694 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
695 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
696
69723rd June 2003 Guy Barrand (opengl-V05-01-02)
698- Commit a first implementation of G4OpenGLWin32Viewer.
699
70010th June 2003 Gabriele Cosmo (opengl-V05-01-01)
701- More fixes for warnings in viewers classes.
702- Added inclusion of <windows.h> for WIN32 platforms when GL headers
703 are included.
704
70505th June 2003 Gabriele Cosmo (opengl-V05-01-00)
706- Fixes for porting compilation on WIN32:
707 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
708 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
709 since declared 'obsolete' in WIN32 platforms.
710
71127th November 2002 John Allison (vis-V04-01-08)
712- Improved algorithm of CompareForKernelVisit.
713
71411th November 2002 John Allison (opengl-V04-01-02)
715- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
716- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
717 call default but there as a marker and encourager.
718- Added tracking and digits+hits/hits to GNUmakefile.
719
72016th October 2002 John Allison (opengl-V04-01-01)
721- Fix for WIN32. Now compiles but viewer not implemented.
722
72324th June 2002 John Allison (opengl-V04-01-00)
724- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
725
72610th June 2002 John Allison (opengl-V04-00-03)
727- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
728
7296th June 2002 John Allison (opengl-V04-00-02)
730- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
731
73223rd February 2002 John Allison (opengl-V04-00-01)
733- Changes to encourage compilation on Windows in preparation for
734 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
735 glx.h, unistd.h and assert.h.
736
73724th August 2001 John Allison (vis-V03-02-13)
738- Limited the printing of warnings in
739 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
740
74114th August 2001 John Allison (vis-V03-02-11)
742- Improved KernelVisitDecision.
743- Fixed a few small bugs in multiple "stored" viewers, but see next item.
744- There's an outstanding bug in OpenGL Stored. If there is more than
745 one viewer controlled by a scene handler, after a ClearStore on the
746 scene handler, e.g., with /vis/scene/notifyHandlers, the first
747 viewer to get refreshed should trigger the display list rebuild, but
748 the second need not. However, when the second viewer's turn comes,
749 the display lists are there, and are called, e.g.,
750 G4OpenGLStoredXViewer::DrawView calls
751 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
752 nothing appears on the screen. To overcome this there is some
753 temporary code in G4VViewer::NeedKernelVisit which marks *all*
754 viewers to force a rebuild. To see the symptoms, comment out that
755 temporary code and issue these commands:
756 /vis/verbose c
757 /control/verbose 2
758 /vis/scene/create
759 /vis/scene/add/volume
760 /vis/sceneHandler/create OGLSX
761 /vis/viewer/create ! ! 1
762 /run/beamOn
763 /vis/viewer/create ! ! 1
764 /vis/viewer/select viewer-0
765 /vis/viewer/viewpointThetaPhi 20 20
766 /vis/viewer/select viewer-1
767 /vis/viewer/viewpointThetaPhi 40 40
768 /vis/viewer/set/style surface
769 /vis/viewer/refresh
770 /vis/viewer/select viewer-0
771 /vis/viewer/refresh
772 /vis/viewer/select viewer-1
773 /vis/viewer/set/style wireframe
774 /vis/scene/notifyHandlers
775 You may have to do this too:
776 /vis/viewer/select viewer-0
777 /vis/scene/notifyHandlers
778 One of the viewers is empty. Curious!!
779
7809th August 2001 John Allison (vis-V03-02-10-00)
781- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
782- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
783 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
784 picked up by inheritance anyway.
785- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
786- Corrected order of calling base class functions in
787 G4OpenGLStoredSceneHandler::Begin/EndModeling.
788
78924th July 2001 John Allison (vis-V03-02-06)
790- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
791
79214th July 2001 John Allison (opengl-V03-02-00)
793- Fixed crash in optimised mode: added Initialise() to viewers so
794 that windows are opened after viewers are fully constructed.
795
7962nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
797- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
798
7997th March 2001 John Allison
800- Changed char* to const char* in many places and that gave problems in
801 calls to Xt and Xm. Hope all's OK. Differences:
802 cvs diff -r vis-V03-00-06 vis-V03-00-07
803
80425th January 2001 John Allison (opengl-V03-00-00)
805- Implemented running re-calculation of up-vector in the case of "object
806 rotation" (lights move with camera) to prevent "flipping" of view when
807 camera passes through up-vector. Note that the default is "camera
808 rotation" (lights do not move with camera, i.e., remain fixed relative
809 to object) so the default is that this "flipping" can happen. To set
810 "object rotation" (lights move with camera) use
811 /vis/lights/move_with_camera true (soon to be
812 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
813 on Rotation Panel in OpenGLXm mode.
814- Changed some objects to references for efficiency. E.g.:
815 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
816
81722nd May 2000 John Allison (opengl-V01-01-00)
818- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
819 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
820 static XVisualInfo* vi_single_buffer;
821 static XVisualInfo* vi_double_buffer;
822- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
823 G4OpenGLXViewer.
824- Protected double deletion of window in destructors of G4OpenGLXmViewer
825 and G4OpenGLXViewer (Guy Barrand).
826- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
827- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
828 constructors.
Note: See TracBrowser for help on using the repository browser.
