302 and "/vis/ogl/printEPS").
303
3048th May 2007 John Allison (opengl-V08-02-06)
305- Moved vectored PostScript printing to G4OpenGLViewer.
306- /vis/ogl/printEPS should work for all viewers, including Win32.
307- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
308 effective on X windows (and still somewhat buggy).
309
3104th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
311- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
312 for OGL*Win32. Still doesn't work for OGL*Xm.
313
3143rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
315- G4OpenGLStoredSceneHandler:
316 o Re-organised display lists on a per-primitive basis, i.e., one
317 display list per primitive. (This is so that, except for text,
318 the colour - or, rather, intensity - can be brought out of the
319 display list into the TOList (Transient Object List) and
320 controlled for the Display-by-Time feature. Previously, if more
321 than one primitive were drawn between BeginPrimitives and
322 EndPrimitives, it would finish up all in one display list, colour
323 commands included. Rationalises and fixes a rare bug in the
324 Display-by-Time feature - see August 2006.)
325 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
326 one primoitive to fit with the above re-organisation.
327- Implemented picking for OGLIX.
328
32925th March 2007 John Allison (opengl-V08-02-03)
330- Fix compiler warnings.
331
3328th February 2007 John Allison (opengl-V08-02-02)
333- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
334- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
335 .but not switched back. Not serious, because context was always set
336 before normal drawing.)
337
3389th January 2007 John Allison (opengl-V08-02-01)
339- Implemented bitmap markers for MarkerSizeType == screen. (The old
340 polygon implementation remains for MarkerSizeType == world.)
341- Added G4OpenGLBitMapStore to assist the above.
342- G4OpenGLXViewer::CreateGLXContext:
343 o Bug fix: Added missing break in colormap lookup routine.
344
3455th January 2007 John Allison (opengl-V08-02-00)
346- G4OpenGLSceneHandler.cc:
347 o Followed change of signature of GetLineWidth in visman-V08-02-00.
348 o Minor efficiency improvements.
349
35021st November 2006 John Allison (opengl-V08-01-09)
351- Fixed compiler warnings.
352
3531st November 2006 John Allison (opengl-V08-01-08)
354- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
355 actually initiates a print, rather than set a flag for printing.
356
35724th October 2006 John Allison (opengl-V08-01-07)
358- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
359- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
360
36119th September 2006 John Allison (opengl-V08-01-06)

364- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
365
3664th September 2006 John Allison (opengl-V08-01-05)
367- Implement cutaways.
368- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
369 primitives (see detector being drawn).
370- /vis/oglx/set/printEPS: change parameter default to true.
371
37230th August 2006 John Allison (opengl-V08-01-04)
373- G4OpenGLSceneHandler:
374 o Implemented line width.
375 o Switched off back face culling when clipping so that the inside of
376 volumes can be seen.
377 o Added CreateSection/CutawayPolyhedron to exploit generic
378 sectioning (DCUT) and cutaways. Currently not activated due to
379 instabilities in BooleanProcessor. Local sectioning still active
380 but broken (at least on Mac) due to apparent change in effect of
381 clipping planes (polyhedron edges not reconstructed).
382 o Rationalised calculation of marker size.
383- G4OpenGLStoredSceneHandler:
384 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
385 o Pick up time range from G4VisAttributes.
386- G4OpenGLViewer(Messenger):
387 o Added position and colour to /vis/ogl/set/displayHeadTime.
388 o Added /vis/ogl/set/displayLightFront.
389- G4OpenGLStoredViewer.cc:
390 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
391 o Added position and colour to DisplayHeadTime.
392 o Added DisplayLightFront.
393
39416th August 2006 John Allison (opengl-V08-01-03)
395- Corrected Solaris compilation error.
396- Added /vis/ogl/set/fade and displayHeadTime.
397
39814th August 2006 John Allison (opengl-V08-01-02)
399- Needs visman-V08-01-02.
400- G4OpenGLStored: Implemented display-by-time. Only available in
401 stored mode at present. Only implemented for circle, square,
402 polyline and polymarker at present, enough for currently available
403 trajectory models. Time is communicated via G4AttValues.
404- Added G4OpenGLViewerMessenger.
405- Added /vis/ogl/set/startTime and endTime of displayed objects.
406- All factories: Instantiated G4OpenGLViewerMessenger.
407- G4OpenGLViewer: Added fStart/EndTime.
408- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
409 spewPrimitiveEPS and spewSortedFeedback.
410
41117th July John Allison (opengl-V08-01-01)
412- Added /vis/oglx/set/printEPS (prints eps file on every update).
413
4143rd July 2006 John Allison (opengl-V08-01-00)
415- Elimination of redundant variable doublebuffer and implementation of
416 FinishView in all viewers.
417
41830th May 2006 Joseph Perl (opengl-V08-00-08)
419- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
420 variable seems to have random behavior and should be assumed false for
421 this viewer.
422
42329th May 2006 Joseph Perl (opengl-V08-00-07)
424- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
425 Removed common FinishView and instead made separate FinishView for the two different
426 versions of this viewer since each wants a different buffer swapping behaviour.
427
42812th May 2006 John Allison (opengl-V08-00-06)
429- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
430
43128th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
432- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
433 recomputing transients.
434
43524th April 2006 John Allison (opengl-V08-00-04)
436- Fixed compilation problem on Windows.
437
43819th April 2006 John Allison (opengl-V08-00-03)
439- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
440 G4OpenGLImmediateSceneHandler:
441 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
442 greps-V08-00-02).
443 o Migrated to direct access to G4PhysicalVolumeModel.
444- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
445 of display lists in DrawView.
446
44714th March 2006 John Allison (opengl-V08-00-02)
448- Refined display list building and re-drawing algorithm.
449 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
450 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
451- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
452 re-use algorithm. In test19 with global culling off, numbers of
453 display lists used are:
454 o 191 No re-use:
455 o 73 Before this change: re-use except replicas (includes parameterised).
456 o 33 After this change: re-use except parameterised and replicas in radius.
457
45826th January 2006 John Allison (opengl-V08-00-01)
459- Coworks with visman-V08-00-04 (removed fModified).
460- Removed references to fModified.
461- Tidying: Removed unnecessary ClearView.
462- G4OpenGLSceneHandler.cc: Added some (commented out) code for
463 possible future implementation of 2D drawing.
464- G4OpenGLXViewer.cc: Improved exception printing.
465
46611th January 2006 John Allison (opengl-V08-00-00)
467- Improved efficiency: all DrawView's:
468 o Don't call ClearView.
469 o Set flag so SetView will not be called in ProcessView.
470 o Leave background colour to ClearView.
471- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
472- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
473 for current viewer.
474
47524th November 2005 John Allison (opengl-V07-01-09)
476- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
477
47822nd November 2005 John Allison (opengl-V07-01-08)
479- Added G4OpenGLXmViewerMessenger.
480- Corrected text position.
481- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
482
48317th November 2005 Gabriele Cosmo
484- Fixed settings of background style for WIN32 viewers.
485
48613th November 2005 John Allison (opengl-V07-01-07)
487- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
488
48913th October 2005 John Allison (opengl-V07-01-06)
490- Allowed any colour background.
491- Implemented non-uniform scaling.
492- Migration to <sstream>.
493
49429th September 2005 John Allison (opengl-V07-01-05)
495- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
496 scene handler.
497- Re-implemented transparency button in OpenGLXm.
498
49913th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
500- Implemented white background for all OGL viewers.
501- G4OpenGLSceneHandler.cc:
502 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
503 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
504 o Corrected GetTextColour(text).
505 o Corrected GetColour(polyhedron).
506
5075th September 2005 John Allison (opengl-V07-01-03)
508- Bug fix: stored transparent objects were being lost.
509
5102nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
511- Bug fix: edgeflags problem introduced with smooth shading in
512 opengl-V07-01-00.
513- Implementation of a "better algorithm" for the rendering of
514 transparent polyhedron objects. It renders all opaque objects
515 first, then renders the transparent objects with the depth buffer in
516 read-only mode (see OpenGL Programming Guide). It uses the new
517 facility in G4VSceneHandler::ProcessScene for an optional second pass
518 of the run-duration models in the scene. Note this algorithm is
519 still only an approximation. It will still give the wrong blended
520 colour if two transparent objects are rendered front first. For
521 nested transparent objects, this is unfortunate, because
522 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
523 in such a way that mothers come first. Also, there is no guaranteed
524 relationship between the order of rendering and the depth of two
525 transparent objects if they are at the same level or in different
526 branches of the hierarchy. Still, the only error will be an
527 incorrect colour - the objects will still give the appearance of
528 transparency, so it's a pretty good algorithm. (An even better
529 algorithm would be to attempt to render the facets in depth order,
530 deepest first. But how do you calculate the depth - centre of area,
531 deepest corner? One can still imagine pathalogical cases that would
532 sometimes give the wrong colour. Also, for stored mode, the order
533 is fixed in a display list so when the user rotates the view, one
534 would lose the depth ordering. I think we have to accept that
535 blending in OpenGL is only ever an approximation. For accurate
536 blending, use RayTracer.)
537
53828th August 2005 John Allison (opengl-V07-01-01)
539- Half-way implementation of rendering of transparent polyhedron
540 objects. In this implementation, no account is taken of the order
541 of rendering. Transparent objects are rendered with depth testing
542 off so that objects behind can still be seen. But this means that
543 opaque objects in front do not obscure them - and they jolly well
544 should! A better algorithm is to render all opaque objects first,
545 then render the transparent objects with the depth buffer in
546 read-only mode (see OpenGL Programming Guide). This is going to
547 take a little more thought - see opengl-V07-01-02.
548
54920th July 2005 John Allison (opengl-V07-01-00)
550- Introduced smooth shading, taking advantage of hitherto un-noticed
551 feature of HepPolyhedron::GetNextFacet that calculates the normals
552 at each vertex so that curved surfaces are rendered more
553 realistically (Gouraud shading).
554- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
555- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
556 the default window size. It used to be 400x400, hardcoded in
557 G4OpenGLXmViewer.cc, but now it picks up the
558 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
559 The user may change it on the command line, e.g:
560 /vis/open OGLSXm 500
561 or
562 /vis/viewer/create ! ! 500
563
56430th May 2005 John Allison (opengl-V07-00-03)
565- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
566 map of vectors in G4OpenGLFontBaseStore.)
567
5684th May 2005 John Allison (opengl-V07-00-02)
569- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
570 was taken out to prevent recursive calling, but that seems to be OK,
571 and it is needed to implement refresh at end of event/run.)
572
57322nd April 2005 John Allison (opengl-V07-00-01)
574- Rationalised work of opengl-V07-00-00. Functionality unchanged.
575 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
576 o In all concrete viewers, added call to CreateFontLists().
577 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
578 o There is no longer a need to implement in the XmViewer, since it
579 now inherits. Thus the font code now only appears once for X.
580 o Awaiting implementation for WIN32.
581
58217th April 2005 John Allison (opengl-V07-00-00)
583- Based on vis-V07-00-13.
584- Implemented text for X-Windows viewers. Uses glXUseXFont, which
585 creates display lists for nominated fonts. Simple-minded scheme in
586 which each viewer creates its own font display lists for a variety
587 of sizes, which are accessed by the scene handler through a new
588 class, G4OpenGLFontBaseStore. Affected methods:
589 G4OpenGLXViewer::CreateMainWindow()
590 G4OpenGLXmViewer::CreateMainWindow()
591 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
592
59318th November 2004 John Allison (opengl-V06-02-07)
594- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
595
59615th November 2004 Guy Barrand
597- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
598 to see trajectories (for example with N03). Correct so that
599 ShowView do a FinishView that does : glFlush, wglSwapBuffer
600 and empty the Windows message queue.
601
60222nd September 2004 John Allison (opengl-V06-02-06)
603- doxygen output to tmp area.
604- Trap non-regular polyhedrons.
605
60613th September 2004 Gabriele Cosmo (opengl-V06-02-05)
607- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
608 to allow for porting on CLHEP-1.9.X series.
609
61023rd July 2004 John Allison
611- Draws auxiliary edges if required.
612- Added auxiliary edge button.
613
61416th July 2004 John Allison (opengl-V06-02-04)
615- Refinements to hidden line, hidden surface removal.
616
61714th July 2004 John Allison (opengl-V06-02-03)
618- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
619
62013th July 2004 John Allison (opengl-V06-02-02)
621- Hidden line *and* hidden surface removal now works.
622
6239th July 2004 John Allison (opengl-V06-02-01)
624- Fixed long-standing problem with hidden line removal.
625- Improved messages on failure to get visual.
626- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
627 systems provided by default anyway, so no effect.
628
6291st July 2004 John Allison (opengl-V06-02-00)
630- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
631- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
632
63318th June 2004 Gunter Folger (geant4-06-02)
6349th June 2004 Gabriele Cosmo (vis-V06-01-03)
6357th June 2004 Gabriele Cosmo (vis-V06-01-02)
636- GNUmakefile and disclaimer changes - see visualization/History.
637
6389th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
639- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
640
6417th April 2004 Guy Barrand
642- visualization/OpenGL/* : use the G4OpenGL.hh file.
643- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
644 the include of gl/gl.h and gl/glu.h that may be platform dependant.
645 It permits to rm some #ifdef WIN32 spread in the code. It opens also
646 the way to the usage of the Apple OpenGL on a Mac.
647
64817th February 2004 John Allison (opengl-V06-00-00)
649- Fixed bug #581: wrong order of statements in
650 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
651
6524th October 2003 Gabriele Cosmo (vis-V05-02-01)
653- GNUmakefile:
654 o replaced "digits+hits" with "digits_hits".
655- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
656
65722nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
658- Cosmetic change to regularise names:
659 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
660 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
661
66223rd June 2003 Guy Barrand (opengl-V05-01-02)
663- Commit a first implementation of G4OpenGLWin32Viewer.
664
66510th June 2003 Gabriele Cosmo (opengl-V05-01-01)
666- More fixes for warnings in viewers classes.
667- Added inclusion of <windows.h> for WIN32 platforms when GL headers
668 are included.
669
67005th June 2003 Gabriele Cosmo (opengl-V05-01-00)
671- Fixes for porting compilation on WIN32:
672 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
673 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
674 since declared 'obsolete' in WIN32 platforms.
675
67627th November 2002 John Allison (vis-V04-01-08)
677- Improved algorithm of CompareForKernelVisit.
678
67911th November 2002 John Allison (opengl-V04-01-02)
680- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
681- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
682 call default but there as a marker and encourager.
683- Added tracking and digits+hits/hits to GNUmakefile.
684
68516th October 2002 John Allison (opengl-V04-01-01)
686- Fix for WIN32. Now compiles but viewer not implemented.
687
68824th June 2002 John Allison (opengl-V04-01-00)
689- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
690
69110th June 2002 John Allison (opengl-V04-00-03)
692- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
693
6946th June 2002 John Allison (opengl-V04-00-02)
695- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
696
69723rd February 2002 John Allison (opengl-V04-00-01)
698- Changes to encourage compilation on Windows in preparation for
699 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
700 glx.h, unistd.h and assert.h.
701
70224th August 2001 John Allison (vis-V03-02-13)
703- Limited the printing of warnings in
704 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
705
70614th August 2001 John Allison (vis-V03-02-11)
707- Improved KernelVisitDecision.
708- Fixed a few small bugs in multiple "stored" viewers, but see next item.
709- There's an outstanding bug in OpenGL Stored. If there is more than
710 one viewer controlled by a scene handler, after a ClearStore on the
711 scene handler, e.g., with /vis/scene/notifyHandlers, the first
712 viewer to get refreshed should trigger the display list rebuild, but
713 the second need not. However, when the second viewer's turn comes,
714 the display lists are there, and are called, e.g.,
715 G4OpenGLStoredXViewer::DrawView calls
716 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
717 nothing appears on the screen. To overcome this there is some
718 temporary code in G4VViewer::NeedKernelVisit which marks *all*
719 viewers to force a rebuild. To see the symptoms, comment out that
720 temporary code and issue these commands:
721 /vis/verbose c
722 /control/verbose 2
723 /vis/scene/create
724 /vis/scene/add/volume
725 /vis/sceneHandler/create OGLSX
726 /vis/viewer/create ! ! 1
727 /run/beamOn
728 /vis/viewer/create ! ! 1
729 /vis/viewer/select viewer-0
730 /vis/viewer/viewpointThetaPhi 20 20
731 /vis/viewer/select viewer-1
732 /vis/viewer/viewpointThetaPhi 40 40
733 /vis/viewer/set/style surface
734 /vis/viewer/refresh
735 /vis/viewer/select viewer-0
736 /vis/viewer/refresh
737 /vis/viewer/select viewer-1
738 /vis/viewer/set/style wireframe
739 /vis/scene/notifyHandlers
740 You may have to do this too:
741 /vis/viewer/select viewer-0
742 /vis/scene/notifyHandlers
743 One of the viewers is empty. Curious!!
744
7459th August 2001 John Allison (vis-V03-02-10-00)
746- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
747- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
748 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
749 picked up by inheritance anyway.
750- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
751- Corrected order of calling base class functions in
752 G4OpenGLStoredSceneHandler::Begin/EndModeling.
753
75424th July 2001 John Allison (vis-V03-02-06)
755- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
756
75714th July 2001 John Allison (opengl-V03-02-00)
758- Fixed crash in optimised mode: added Initialise() to viewers so
759 that windows are opened after viewers are fully constructed.
760
7612nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
762- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
763
7647th March 2001 John Allison
765- Changed char* to const char* in many places and that gave problems in
766 calls to Xt and Xm. Hope all's OK. Differences:
767 cvs diff -r vis-V03-00-06 vis-V03-00-07
768
76925th January 2001 John Allison (opengl-V03-00-00)
770- Implemented running re-calculation of up-vector in the case of "object
771 rotation" (lights move with camera) to prevent "flipping" of view when
772 camera passes through up-vector. Note that the default is "camera
773 rotation" (lights do not move with camera, i.e., remain fixed relative
774 to object) so the default is that this "flipping" can happen. To set
775 "object rotation" (lights move with camera) use
776 /vis/lights/move_with_camera true (soon to be
777 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
778 on Rotation Panel in OpenGLXm mode.
779- Changed some objects to references for efficiency. E.g.:
780 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
781
78222nd May 2000 John Allison (opengl-V01-01-00)
783- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
784 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
785 static XVisualInfo* vi_single_buffer;
786 static XVisualInfo* vi_double_buffer;
787- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
788 G4OpenGLXViewer.
789- Protected double deletion of window in destructors of G4OpenGLXmViewer
790 and G4OpenGLXViewer (Guy Barrand).
791- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
792- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
793 constructors.
Note: See TracBrowser for help on using the repository browser.
