299- G4OpenGLXViewer: Trapped glXMakeCurrent in Initialise function.
300
30124th May 2007  John Allison  (opengl-V08-03-01)

303
30416th May 2007  John Allison  (opengl-V08-03-00)
305- Fix compiler warnings on SLC4.
306- Bug fixes:
307  o Correct path /vis/ogl/set/printMode.
308  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
309    and "/vis/ogl/printEPS").
310
3118th May 2007  John Allison  (opengl-V08-02-06)
312- Moved vectored PostScript printing to G4OpenGLViewer.
313- /vis/ogl/printEPS should work for all viewers, including Win32.
314- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
315  effective on X windows (and still somewhat buggy).
316
3174th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
318- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
319  for OGL*Win32.  Still doesn't work for OGL*Xm.
320
3213rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
322- G4OpenGLStoredSceneHandler:
323  o Re-organised display lists on a per-primitive basis, i.e., one
324    display list per primitive.  (This is so that, except for text,
325    the colour - or, rather, intensity - can be brought out of the
326    display list into the TOList (Transient Object List) and
327    controlled for the Display-by-Time feature.  Previously, if more
328    than one primitive were drawn between BeginPrimitives and
329    EndPrimitives, it would finish up all in one display list, colour
330    commands included. Rationalises and fixes a rare bug in the
331    Display-by-Time feature - see August 2006.)
332  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
333    one primoitive to fit with the above re-organisation.
334- Implemented picking for OGLIX.
335
33625th March 2007  John Allison  (opengl-V08-02-03)
337- Fix compiler warnings.
338
3398th February 2007  John Allison  (opengl-V08-02-02)
340- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
341- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
342  .but not switched back.  Not serious, because context was always set
343  before normal drawing.)
344
3459th January 2007  John Allison  (opengl-V08-02-01)
346- Implemented bitmap markers for MarkerSizeType == screen.  (The old
347  polygon implementation remains for MarkerSizeType == world.)
348- Added G4OpenGLBitMapStore to assist the above.
349- G4OpenGLXViewer::CreateGLXContext:
350  o Bug fix: Added missing break in colormap lookup routine.
351
3525th January 2007  John Allison  (opengl-V08-02-00)
353- G4OpenGLSceneHandler.cc:
354  o Followed change of signature of GetLineWidth in visman-V08-02-00.
355  o Minor efficiency improvements.
356
35721st November 2006  John Allison  (opengl-V08-01-09)
358- Fixed compiler warnings.
359
3601st November 2006  John Allison  (opengl-V08-01-08)
361- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
362  actually initiates a print, rather than set a flag for printing.
363
36424th October 2006  John Allison  (opengl-V08-01-07)
365- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
366- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
367
36819th September 2006  John Allison  (opengl-V08-01-06)
369- Added time origin for light front.
370- Added /vis/ogl/set/transparency.
371- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
372
3734th September 2006  John Allison  (opengl-V08-01-05)
374- Implement cutaways.
375- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
376  primitives (see detector being drawn).
377- /vis/oglx/set/printEPS: change parameter default to true.
378
37930th August 2006  John Allison  (opengl-V08-01-04)
380- G4OpenGLSceneHandler:
381  o Implemented line width.
382  o Switched off back face culling when clipping so that the inside of
383    volumes can be seen.
384  o Added CreateSection/CutawayPolyhedron to exploit generic
385    sectioning (DCUT) and cutaways.  Currently not activated due to
386    instabilities in BooleanProcessor.  Local sectioning still active
387    but broken (at least on Mac) due to apparent change in effect of
388    clipping planes (polyhedron edges not reconstructed).
389  o Rationalised calculation of marker size.
390- G4OpenGLStoredSceneHandler:
391  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
392  o Pick up time range from G4VisAttributes.
393- G4OpenGLViewer(Messenger):
394  o Added position and colour to /vis/ogl/set/displayHeadTime.
395  o Added /vis/ogl/set/displayLightFront.
396- G4OpenGLStoredViewer.cc:
397  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
398  o Added position and colour to DisplayHeadTime.
399  o Added DisplayLightFront.
400 
40116th August 2006  John Allison  (opengl-V08-01-03)
402- Corrected Solaris compilation error.
403- Added /vis/ogl/set/fade and displayHeadTime.
404
40514th August 2006  John Allison  (opengl-V08-01-02)
406- Needs visman-V08-01-02.
407- G4OpenGLStored: Implemented display-by-time.  Only available in
408  stored mode at present.  Only implemented for circle, square,
409  polyline and polymarker at present, enough for currently available
410  trajectory models.  Time is communicated via G4AttValues.
411- Added G4OpenGLViewerMessenger.
412- Added /vis/ogl/set/startTime and endTime of displayed objects.
413- All factories: Instantiated G4OpenGLViewerMessenger.
414- G4OpenGLViewer: Added fStart/EndTime.
415- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
416  spewPrimitiveEPS and spewSortedFeedback.
417
41817th July  John Allison  (opengl-V08-01-01)
419- Added /vis/oglx/set/printEPS (prints eps file on every update).
420
4213rd July 2006  John Allison  (opengl-V08-01-00)
422- Elimination of redundant variable doublebuffer and implementation of
423  FinishView in all viewers.
424
42530th May 2006  Joseph Perl  (opengl-V08-00-08)
426- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
427  variable seems to have random behavior and should be assumed false for
428  this viewer.
429
43029th May 2006  Joseph Perl  (opengl-V08-00-07)
431- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
432  Removed common FinishView and instead made separate FinishView for the two different
433  versions of this viewer since each wants a different buffer swapping behaviour.
434
43512th May 2006  John Allison  (opengl-V08-00-06)
436- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
437
43828th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
439- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
440  recomputing transients.
441
44224th April 2006  John Allison  (opengl-V08-00-04)
443- Fixed compilation problem on Windows.
444
44519th April 2006  John Allison  (opengl-V08-00-03)
446- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
447  G4OpenGLImmediateSceneHandler:
448  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
449    greps-V08-00-02).
450  o Migrated to direct access to G4PhysicalVolumeModel.
451- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
452  of display lists in DrawView.
453
45414th March 2006  John Allison  (opengl-V08-00-02)
455- Refined display list building and re-drawing algorithm.
456  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
457  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
458- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
459  re-use algorithm.  In test19 with global culling off, numbers of
460  display lists used are:
461  o 191  No re-use:
462  o  73  Before this change: re-use except replicas (includes parameterised).
463  o  33  After this change: re-use except parameterised and replicas in radius.
464
46526th January 2006  John Allison  (opengl-V08-00-01)
466- Coworks with visman-V08-00-04 (removed fModified).
467- Removed references to fModified.
468- Tidying: Removed unnecessary ClearView.
469- G4OpenGLSceneHandler.cc: Added some (commented out) code for
470  possible future implementation of 2D drawing.
471- G4OpenGLXViewer.cc: Improved exception printing.
472
47311th January 2006  John Allison  (opengl-V08-00-00)
474- Improved efficiency: all DrawView's:
475  o Don't call ClearView.
476  o Set flag so SetView will not be called in ProcessView.
477  o Leave background colour to ClearView.
478- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
479- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
480  for current viewer.
481
48224th November 2005  John Allison  (opengl-V07-01-09)
483- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
484
48522nd November 2005  John Allison  (opengl-V07-01-08)
486- Added G4OpenGLXmViewerMessenger.
487- Corrected text position.
488- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
489
49017th November 2005  Gabriele Cosmo
491- Fixed settings of background style for WIN32 viewers.
492
49313th November 2005  John Allison  (opengl-V07-01-07)
494- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
495
49613th October 2005  John Allison  (opengl-V07-01-06)
497- Allowed any colour background.
498- Implemented non-uniform scaling.
499- Migration to <sstream>.
500
50129th September 2005  John Allison  (opengl-V07-01-05)
502- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
503  scene handler.
504- Re-implemented transparency button in OpenGLXm.
505
50613th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
507- Implemented white background for all OGL viewers.
508- G4OpenGLSceneHandler.cc:
509  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
510  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
511  o Corrected GetTextColour(text).
512  o Corrected GetColour(polyhedron).
513
5145th September 2005  John Allison  (opengl-V07-01-03)
515- Bug fix: stored transparent objects were being lost.
516
5172nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
518- Bug fix: edgeflags problem introduced with smooth shading in
519  opengl-V07-01-00.
520- Implementation of a "better algorithm" for the rendering of
521  transparent polyhedron objects.  It renders all opaque objects
522  first, then renders the transparent objects with the depth buffer in
523  read-only mode (see OpenGL Programming Guide).  It uses the new
524  facility in G4VSceneHandler::ProcessScene for an optional second pass
525  of the run-duration models in the scene.  Note this algorithm is
526  still only an approximation.  It will still give the wrong blended
527  colour if two transparent objects are rendered front first.  For
528  nested transparent objects, this is unfortunate, because
529  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
530  in such a way that mothers come first.  Also, there is no guaranteed
531  relationship between the order of rendering and the depth of two
532  transparent objects if they are at the same level or in different
533  branches of the hierarchy.  Still, the only error will be an
534  incorrect colour - the objects will still give the appearance of
535  transparency, so it's a pretty good algorithm.  (An even better
536  algorithm would be to attempt to render the facets in depth order,
537  deepest first.  But how do you calculate the depth - centre of area,
538  deepest corner?  One can still imagine pathalogical cases that would
539  sometimes give the wrong colour.  Also, for stored mode, the order
540  is fixed in a display list so when the user rotates the view, one
541  would lose the depth ordering.  I think we have to accept that
542  blending in OpenGL is only ever an approximation.  For accurate
543  blending, use RayTracer.)
544
54528th August 2005  John Allison  (opengl-V07-01-01)
546- Half-way implementation of rendering of transparent polyhedron
547  objects.  In this implementation, no account is taken of the order
548  of rendering.  Transparent objects are rendered with depth testing
549  off so that objects behind can still be seen.  But this means that
550  opaque objects in front do not obscure them - and they jolly well
551  should!  A better algorithm is to render all opaque objects first,
552  then render the transparent objects with the depth buffer in
553  read-only mode (see OpenGL Programming Guide).  This is going to
554  take a little more thought - see opengl-V07-01-02.
555
55620th July 2005  John Allison  (opengl-V07-01-00)
557- Introduced smooth shading, taking advantage of hitherto un-noticed
558  feature of HepPolyhedron::GetNextFacet that calculates the normals
559  at each vertex so that curved surfaces are rendered more
560  realistically (Gouraud shading).
561- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
562- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
563  the default window size.  It used to be 400x400, hardcoded in
564  G4OpenGLXmViewer.cc, but now it picks up the
565  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
566  The user may change it on the command line, e.g:
567    /vis/open OGLSXm 500
568  or
569    /vis/viewer/create ! ! 500
570
57130th May 2005  John Allison  (opengl-V07-00-03)
572- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
573  map of vectors in G4OpenGLFontBaseStore.)
574
5754th May 2005  John Allison  (opengl-V07-00-02)
576- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
577  was taken out to prevent recursive calling, but that seems to be OK,
578  and it is needed to implement refresh at end of event/run.)
579
58022nd April 2005  John Allison  (opengl-V07-00-01)
581- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
582  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
583  o In all concrete viewers, added call to CreateFontLists().
584  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
585  o There is no longer a need to implement in the XmViewer, since it
586    now inherits.  Thus the font code now only appears once for X.
587  o Awaiting implementation for WIN32.
588
58917th April 2005  John Allison  (opengl-V07-00-00)
590- Based on vis-V07-00-13.
591- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
592  creates display lists for nominated fonts.  Simple-minded scheme in
593  which each viewer creates its own font display lists for a variety
594  of sizes, which are accessed by the scene handler through a new
595  class, G4OpenGLFontBaseStore.  Affected methods:
596    G4OpenGLXViewer::CreateMainWindow()
597    G4OpenGLXmViewer::CreateMainWindow()
598    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
599
60018th November 2004  John Allison  (opengl-V06-02-07)
601- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
602
60315th November 2004  Guy Barrand
604- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
605  to see trajectories (for example with N03). Correct so that
606  ShowView do a FinishView that does : glFlush, wglSwapBuffer
607  and empty the Windows message queue.
608
60922nd September 2004  John Allison  (opengl-V06-02-06)
610- doxygen output to tmp area.
611- Trap non-regular polyhedrons.
612
61313th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
614- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
615  to allow for porting on CLHEP-1.9.X series.
616
61723rd July 2004  John Allison
618- Draws auxiliary edges if required.
619- Added auxiliary edge button.
620
62116th July 2004  John Allison  (opengl-V06-02-04)
622- Refinements to hidden line, hidden surface removal.
623
62414th July 2004  John Allison  (opengl-V06-02-03)
625- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
626
62713th July 2004  John Allison  (opengl-V06-02-02)
628- Hidden line *and* hidden surface removal now works.
629
6309th July 2004  John Allison  (opengl-V06-02-01)
631- Fixed long-standing problem with hidden line removal.
632- Improved messages on failure to get visual.
633- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
634  systems provided by default anyway, so no effect.
635
6361st July 2004  John Allison  (opengl-V06-02-00)
637- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
638- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
639
64018th June 2004  Gunter Folger (geant4-06-02)
6419th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6427th June 2004  Gabriele Cosmo  (vis-V06-01-02)
643- GNUmakefile and disclaimer changes - see visualization/History.
644
6459th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
646- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
647
6487th April 2004  Guy Barrand
649- visualization/OpenGL/* : use the G4OpenGL.hh file.
650- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
651  the include of gl/gl.h and gl/glu.h that may be platform dependant.
652  It permits to rm some #ifdef WIN32 spread in the code. It opens also
653  the way to the usage of the Apple OpenGL on a Mac.
654
65517th February 2004  John Allison  (opengl-V06-00-00)
656- Fixed bug #581: wrong order of statements in
657  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
658
6594th October 2003  Gabriele Cosmo  (vis-V05-02-01)
660- GNUmakefile:
661  o replaced "digits+hits" with "digits_hits".
662- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
663
66422nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
665- Cosmetic change to regularise names:
666  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
667  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
668
66923rd June 2003  Guy Barrand  (opengl-V05-01-02)
670- Commit a first implementation of G4OpenGLWin32Viewer.
671
67210th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
673- More fixes for warnings in viewers classes.
674- Added inclusion of <windows.h> for WIN32 platforms when GL headers
675  are included.
676
67705th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
678- Fixes for porting compilation on WIN32:
679  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
680  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
681    since declared 'obsolete' in WIN32 platforms.
682
68327th November 2002  John Allison  (vis-V04-01-08)
684- Improved algorithm of CompareForKernelVisit.
685
68611th November 2002  John Allison  (opengl-V04-01-02)
687- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
688- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
689  call default but there as a marker and encourager.
690- Added tracking and digits+hits/hits to GNUmakefile.
691
69216th October 2002  John Allison  (opengl-V04-01-01)
693- Fix for WIN32.  Now compiles but viewer not implemented.
694
69524th June 2002  John Allison  (opengl-V04-01-00)
696- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
697
69810th June 2002  John Allison  (opengl-V04-00-03)
699- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
700
7016th June 2002  John Allison  (opengl-V04-00-02)
702- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
703
70423rd February 2002  John Allison  (opengl-V04-00-01)
705- Changes to encourage compilation on Windows in preparation for
706  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
707  glx.h, unistd.h and assert.h.
708
70924th August 2001  John Allison  (vis-V03-02-13)
710- Limited the printing of warnings in
711  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
712
71314th August 2001  John Allison  (vis-V03-02-11)
714- Improved KernelVisitDecision.
715- Fixed a few small bugs in multiple "stored" viewers, but see next item.
716- There's an outstanding bug in OpenGL Stored.  If there is more than
717  one viewer controlled by a scene handler, after a ClearStore on the
718  scene handler, e.g., with /vis/scene/notifyHandlers, the first
719  viewer to get refreshed should trigger the display list rebuild, but
720  the second need not.  However, when the second viewer's turn comes,
721  the display lists are there, and are called, e.g.,
722  G4OpenGLStoredXViewer::DrawView calls
723  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
724  nothing appears on the screen.  To overcome this there is some
725  temporary code in G4VViewer::NeedKernelVisit which marks *all*
726  viewers to force a rebuild.  To see the symptoms, comment out that
727  temporary code and issue these commands:
728    /vis/verbose c
729    /control/verbose 2
730    /vis/scene/create
731    /vis/scene/add/volume
732    /vis/sceneHandler/create OGLSX
733    /vis/viewer/create ! ! 1
734    /run/beamOn
735    /vis/viewer/create ! ! 1
736    /vis/viewer/select viewer-0
737    /vis/viewer/viewpointThetaPhi 20 20
738    /vis/viewer/select viewer-1
739    /vis/viewer/viewpointThetaPhi 40 40
740    /vis/viewer/set/style surface
741    /vis/viewer/refresh
742    /vis/viewer/select viewer-0
743    /vis/viewer/refresh
744    /vis/viewer/select viewer-1
745    /vis/viewer/set/style wireframe
746    /vis/scene/notifyHandlers
747  You may have to do this too:
748    /vis/viewer/select viewer-0
749    /vis/scene/notifyHandlers
750  One of the viewers is empty.  Curious!!
751
7529th August 2001  John Allison  (vis-V03-02-10-00)
753- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
754- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
755  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
756  picked up by inheritance anyway.
757- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
758- Corrected order of calling base class functions in
759  G4OpenGLStoredSceneHandler::Begin/EndModeling.
760
76124th July 2001  John Allison  (vis-V03-02-06)
762- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
763
76414th July 2001  John Allison (opengl-V03-02-00)
765- Fixed crash in optimised mode: added Initialise() to viewers so
766  that windows are opened after viewers are fully constructed.
767
7682nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
769- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
770
7717th March 2001  John Allison
772- Changed char* to const char* in many places and that gave problems in
773  calls to Xt and Xm.  Hope all's OK.  Differences:
774    cvs diff -r vis-V03-00-06 vis-V03-00-07
775
77625th January 2001  John Allison  (opengl-V03-00-00)
777- Implemented running re-calculation of up-vector in the case of "object
778  rotation" (lights move with camera) to prevent "flipping" of view when
779  camera passes through up-vector.  Note that the default is "camera
780  rotation" (lights do not move with camera, i.e., remain fixed relative
781  to object) so the default is that this "flipping" can happen.  To set
782  "object rotation" (lights move with camera) use
783  /vis/lights/move_with_camera true (soon to be
784  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
785  on Rotation Panel in OpenGLXm mode.
786- Changed some objects to references for efficiency.  E.g.:
787  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
788
78922nd May 2000  John Allison  (opengl-V01-01-00)
790- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
791  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
792    static XVisualInfo* vi_single_buffer;
793    static XVisualInfo* vi_double_buffer;
794- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
795  G4OpenGLXViewer.
796- Protected double deletion of window in destructors of G4OpenGLXmViewer
797  and G4OpenGLXViewer (Guy Barrand).
798- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
799- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
800  constructors.
Note: See TracBrowser for help on using the repository browser.
