24 - G4OpenGLViewer.cc : Fix a problem with printing. On mac OSX version
25   > 10.5.7? or Ubuntu > 9.04? AND with user account configure in french
26   (or canadian I believe), the decimal point character was defined by
27   "," (see LC_NUMERIC). This cause a problem on reading eps files.
28   Changed "," to "."

300- Removed redundant G4OpenGLXViewerMessenger.
301
30225th May 2007  John Allison  (opengl-V08-03-03)
303- G4OpenGLSceneHandler and G4OpenGLXViewerMessenger:
304  Fixed gcc-4.1.2 compiler warnings.
305
30625th May 2007  John Allison  (opengl-V08-03-02)
307- G4OpenGLXViewer: Trapped glXMakeCurrent in Initialise function.
308
30924th May 2007  John Allison  (opengl-V08-03-01)
310- Fixes for SUN.
311
31216th May 2007  John Allison  (opengl-V08-03-00)
313- Fix compiler warnings on SLC4.
314- Bug fixes:
315  o Correct path /vis/ogl/set/printMode.
316  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
317    and "/vis/ogl/printEPS").
318
3198th May 2007  John Allison  (opengl-V08-02-06)
320- Moved vectored PostScript printing to G4OpenGLViewer.
321- /vis/ogl/printEPS should work for all viewers, including Win32.
322- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
323  effective on X windows (and still somewhat buggy).
324
3254th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
326- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
327  for OGL*Win32.  Still doesn't work for OGL*Xm.
328
3293rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
330- G4OpenGLStoredSceneHandler:
331  o Re-organised display lists on a per-primitive basis, i.e., one
332    display list per primitive.  (This is so that, except for text,
333    the colour - or, rather, intensity - can be brought out of the
334    display list into the TOList (Transient Object List) and
335    controlled for the Display-by-Time feature.  Previously, if more
336    than one primitive were drawn between BeginPrimitives and
337    EndPrimitives, it would finish up all in one display list, colour
338    commands included. Rationalises and fixes a rare bug in the
339    Display-by-Time feature - see August 2006.)
340  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
341    one primoitive to fit with the above re-organisation.
342- Implemented picking for OGLIX.
343
34425th March 2007  John Allison  (opengl-V08-02-03)
345- Fix compiler warnings.
346
3478th February 2007  John Allison  (opengl-V08-02-02)
348- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
349- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
350  .but not switched back.  Not serious, because context was always set
351  before normal drawing.)
352
3539th January 2007  John Allison  (opengl-V08-02-01)
354- Implemented bitmap markers for MarkerSizeType == screen.  (The old
355  polygon implementation remains for MarkerSizeType == world.)
356- Added G4OpenGLBitMapStore to assist the above.
357- G4OpenGLXViewer::CreateGLXContext:
358  o Bug fix: Added missing break in colormap lookup routine.
359
3605th January 2007  John Allison  (opengl-V08-02-00)
361- G4OpenGLSceneHandler.cc:
362  o Followed change of signature of GetLineWidth in visman-V08-02-00.
363  o Minor efficiency improvements.
364
36521st November 2006  John Allison  (opengl-V08-01-09)
366- Fixed compiler warnings.
367
3681st November 2006  John Allison  (opengl-V08-01-08)
369- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
370  actually initiates a print, rather than set a flag for printing.
371
37224th October 2006  John Allison  (opengl-V08-01-07)
373- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
374- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
375
37619th September 2006  John Allison  (opengl-V08-01-06)
377- Added time origin for light front.
378- Added /vis/ogl/set/transparency.
379- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
380
3814th September 2006  John Allison  (opengl-V08-01-05)
382- Implement cutaways.
383- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
384  primitives (see detector being drawn).
385- /vis/oglx/set/printEPS: change parameter default to true.
386
38730th August 2006  John Allison  (opengl-V08-01-04)
388- G4OpenGLSceneHandler:
389  o Implemented line width.
390  o Switched off back face culling when clipping so that the inside of
391    volumes can be seen.
392  o Added CreateSection/CutawayPolyhedron to exploit generic
393    sectioning (DCUT) and cutaways.  Currently not activated due to
394    instabilities in BooleanProcessor.  Local sectioning still active
395    but broken (at least on Mac) due to apparent change in effect of
396    clipping planes (polyhedron edges not reconstructed).
397  o Rationalised calculation of marker size.
398- G4OpenGLStoredSceneHandler:
399  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
400  o Pick up time range from G4VisAttributes.
401- G4OpenGLViewer(Messenger):
402  o Added position and colour to /vis/ogl/set/displayHeadTime.
403  o Added /vis/ogl/set/displayLightFront.
404- G4OpenGLStoredViewer.cc:
405  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
406  o Added position and colour to DisplayHeadTime.
407  o Added DisplayLightFront.
408 
40916th August 2006  John Allison  (opengl-V08-01-03)
410- Corrected Solaris compilation error.
411- Added /vis/ogl/set/fade and displayHeadTime.
412
41314th August 2006  John Allison  (opengl-V08-01-02)
414- Needs visman-V08-01-02.
415- G4OpenGLStored: Implemented display-by-time.  Only available in
416  stored mode at present.  Only implemented for circle, square,
417  polyline and polymarker at present, enough for currently available
418  trajectory models.  Time is communicated via G4AttValues.
419- Added G4OpenGLViewerMessenger.
420- Added /vis/ogl/set/startTime and endTime of displayed objects.
421- All factories: Instantiated G4OpenGLViewerMessenger.
422- G4OpenGLViewer: Added fStart/EndTime.
423- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
424  spewPrimitiveEPS and spewSortedFeedback.
425
42617th July  John Allison  (opengl-V08-01-01)
427- Added /vis/oglx/set/printEPS (prints eps file on every update).
428
4293rd July 2006  John Allison  (opengl-V08-01-00)
430- Elimination of redundant variable doublebuffer and implementation of
431  FinishView in all viewers.
432
43330th May 2006  Joseph Perl  (opengl-V08-00-08)
434- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
435  variable seems to have random behavior and should be assumed false for
436  this viewer.
437
43829th May 2006  Joseph Perl  (opengl-V08-00-07)
439- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
440  Removed common FinishView and instead made separate FinishView for the two different
441  versions of this viewer since each wants a different buffer swapping behaviour.

445
44628th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
447- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
448  recomputing transients.
449
45024th April 2006  John Allison  (opengl-V08-00-04)
451- Fixed compilation problem on Windows.
452
45319th April 2006  John Allison  (opengl-V08-00-03)
454- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
455  G4OpenGLImmediateSceneHandler:
456  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
457    greps-V08-00-02).
458  o Migrated to direct access to G4PhysicalVolumeModel.
459- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
460  of display lists in DrawView.
461
46214th March 2006  John Allison  (opengl-V08-00-02)
463- Refined display list building and re-drawing algorithm.
464  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
465  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
466- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
467  re-use algorithm.  In test19 with global culling off, numbers of
468  display lists used are:
469  o 191  No re-use:
470  o  73  Before this change: re-use except replicas (includes parameterised).
471  o  33  After this change: re-use except parameterised and replicas in radius.
472
47326th January 2006  John Allison  (opengl-V08-00-01)
474- Coworks with visman-V08-00-04 (removed fModified).
475- Removed references to fModified.
476- Tidying: Removed unnecessary ClearView.
477- G4OpenGLSceneHandler.cc: Added some (commented out) code for
478  possible future implementation of 2D drawing.
479- G4OpenGLXViewer.cc: Improved exception printing.
480
48111th January 2006  John Allison  (opengl-V08-00-00)
482- Improved efficiency: all DrawView's:
483  o Don't call ClearView.
484  o Set flag so SetView will not be called in ProcessView.
485  o Leave background colour to ClearView.
486- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
487- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
488  for current viewer.
489
49024th November 2005  John Allison  (opengl-V07-01-09)
491- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
492
49322nd November 2005  John Allison  (opengl-V07-01-08)
494- Added G4OpenGLXmViewerMessenger.
495- Corrected text position.
496- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
497
49817th November 2005  Gabriele Cosmo
499- Fixed settings of background style for WIN32 viewers.
500
50113th November 2005  John Allison  (opengl-V07-01-07)
502- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
503
50413th October 2005  John Allison  (opengl-V07-01-06)
505- Allowed any colour background.
506- Implemented non-uniform scaling.
507- Migration to <sstream>.
508
50929th September 2005  John Allison  (opengl-V07-01-05)
510- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
511  scene handler.
512- Re-implemented transparency button in OpenGLXm.
513
51413th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
515- Implemented white background for all OGL viewers.
516- G4OpenGLSceneHandler.cc:
517  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
518  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
519  o Corrected GetTextColour(text).
520  o Corrected GetColour(polyhedron).
521
5225th September 2005  John Allison  (opengl-V07-01-03)
523- Bug fix: stored transparent objects were being lost.
524
5252nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
526- Bug fix: edgeflags problem introduced with smooth shading in
527  opengl-V07-01-00.
528- Implementation of a "better algorithm" for the rendering of
529  transparent polyhedron objects.  It renders all opaque objects
530  first, then renders the transparent objects with the depth buffer in
531  read-only mode (see OpenGL Programming Guide).  It uses the new
532  facility in G4VSceneHandler::ProcessScene for an optional second pass
533  of the run-duration models in the scene.  Note this algorithm is
534  still only an approximation.  It will still give the wrong blended
535  colour if two transparent objects are rendered front first.  For
536  nested transparent objects, this is unfortunate, because
537  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
538  in such a way that mothers come first.  Also, there is no guaranteed
539  relationship between the order of rendering and the depth of two
540  transparent objects if they are at the same level or in different
541  branches of the hierarchy.  Still, the only error will be an
542  incorrect colour - the objects will still give the appearance of
543  transparency, so it's a pretty good algorithm.  (An even better
544  algorithm would be to attempt to render the facets in depth order,
545  deepest first.  But how do you calculate the depth - centre of area,
546  deepest corner?  One can still imagine pathalogical cases that would
547  sometimes give the wrong colour.  Also, for stored mode, the order
548  is fixed in a display list so when the user rotates the view, one
549  would lose the depth ordering.  I think we have to accept that
550  blending in OpenGL is only ever an approximation.  For accurate
551  blending, use RayTracer.)
552
55328th August 2005  John Allison  (opengl-V07-01-01)
554- Half-way implementation of rendering of transparent polyhedron
555  objects.  In this implementation, no account is taken of the order
556  of rendering.  Transparent objects are rendered with depth testing
557  off so that objects behind can still be seen.  But this means that
558  opaque objects in front do not obscure them - and they jolly well
559  should!  A better algorithm is to render all opaque objects first,
560  then render the transparent objects with the depth buffer in
561  read-only mode (see OpenGL Programming Guide).  This is going to
562  take a little more thought - see opengl-V07-01-02.
563
56420th July 2005  John Allison  (opengl-V07-01-00)
565- Introduced smooth shading, taking advantage of hitherto un-noticed
566  feature of HepPolyhedron::GetNextFacet that calculates the normals
567  at each vertex so that curved surfaces are rendered more
568  realistically (Gouraud shading).
569- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
570- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
571  the default window size.  It used to be 400x400, hardcoded in
572  G4OpenGLXmViewer.cc, but now it picks up the
573  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
574  The user may change it on the command line, e.g:
575    /vis/open OGLSXm 500
576  or
577    /vis/viewer/create ! ! 500
578
57930th May 2005  John Allison  (opengl-V07-00-03)
580- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
581  map of vectors in G4OpenGLFontBaseStore.)
582
5834th May 2005  John Allison  (opengl-V07-00-02)
584- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
585  was taken out to prevent recursive calling, but that seems to be OK,
586  and it is needed to implement refresh at end of event/run.)
587
58822nd April 2005  John Allison  (opengl-V07-00-01)
589- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
590  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
591  o In all concrete viewers, added call to CreateFontLists().
592  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
593  o There is no longer a need to implement in the XmViewer, since it
594    now inherits.  Thus the font code now only appears once for X.
595  o Awaiting implementation for WIN32.
596
59717th April 2005  John Allison  (opengl-V07-00-00)
598- Based on vis-V07-00-13.
599- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
600  creates display lists for nominated fonts.  Simple-minded scheme in
601  which each viewer creates its own font display lists for a variety
602  of sizes, which are accessed by the scene handler through a new
603  class, G4OpenGLFontBaseStore.  Affected methods:
604    G4OpenGLXViewer::CreateMainWindow()
605    G4OpenGLXmViewer::CreateMainWindow()
606    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
607
60818th November 2004  John Allison  (opengl-V06-02-07)
609- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
610
61115th November 2004  Guy Barrand
612- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
613  to see trajectories (for example with N03). Correct so that
614  ShowView do a FinishView that does : glFlush, wglSwapBuffer
615  and empty the Windows message queue.
616
61722nd September 2004  John Allison  (opengl-V06-02-06)
618- doxygen output to tmp area.
619- Trap non-regular polyhedrons.
620
62113th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
622- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
623  to allow for porting on CLHEP-1.9.X series.
624
62523rd July 2004  John Allison
626- Draws auxiliary edges if required.
627- Added auxiliary edge button.
628
62916th July 2004  John Allison  (opengl-V06-02-04)
630- Refinements to hidden line, hidden surface removal.
631
63214th July 2004  John Allison  (opengl-V06-02-03)
633- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
634
63513th July 2004  John Allison  (opengl-V06-02-02)
636- Hidden line *and* hidden surface removal now works.
637
6389th July 2004  John Allison  (opengl-V06-02-01)
639- Fixed long-standing problem with hidden line removal.
640- Improved messages on failure to get visual.
641- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
642  systems provided by default anyway, so no effect.
643
6441st July 2004  John Allison  (opengl-V06-02-00)
645- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
646- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
647
64818th June 2004  Gunter Folger (geant4-06-02)
6499th June 2004  Gabriele Cosmo  (vis-V06-01-03)
6507th June 2004  Gabriele Cosmo  (vis-V06-01-02)
651- GNUmakefile and disclaimer changes - see visualization/History.
652
6539th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
654- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
655
6567th April 2004  Guy Barrand
657- visualization/OpenGL/* : use the G4OpenGL.hh file.
658- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
659  the include of gl/gl.h and gl/glu.h that may be platform dependant.
660  It permits to rm some #ifdef WIN32 spread in the code. It opens also
661  the way to the usage of the Apple OpenGL on a Mac.
662
66317th February 2004  John Allison  (opengl-V06-00-00)
664- Fixed bug #581: wrong order of statements in
665  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
666
6674th October 2003  Gabriele Cosmo  (vis-V05-02-01)
668- GNUmakefile:
669  o replaced "digits+hits" with "digits_hits".
670- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
671
67222nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
673- Cosmetic change to regularise names:
674  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
675  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
676
67723rd June 2003  Guy Barrand  (opengl-V05-01-02)
678- Commit a first implementation of G4OpenGLWin32Viewer.
679
68010th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
681- More fixes for warnings in viewers classes.
682- Added inclusion of <windows.h> for WIN32 platforms when GL headers
683  are included.
684
68505th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
686- Fixes for porting compilation on WIN32:
687  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
688  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
689    since declared 'obsolete' in WIN32 platforms.
690
69127th November 2002  John Allison  (vis-V04-01-08)
692- Improved algorithm of CompareForKernelVisit.
693
69411th November 2002  John Allison  (opengl-V04-01-02)
695- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
696- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
697  call default but there as a marker and encourager.
698- Added tracking and digits+hits/hits to GNUmakefile.
699
70016th October 2002  John Allison  (opengl-V04-01-01)
701- Fix for WIN32.  Now compiles but viewer not implemented.
702
70324th June 2002  John Allison  (opengl-V04-01-00)
704- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
705
70610th June 2002  John Allison  (opengl-V04-00-03)
707- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
708
7096th June 2002  John Allison  (opengl-V04-00-02)
710- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
711
71223rd February 2002  John Allison  (opengl-V04-00-01)
713- Changes to encourage compilation on Windows in preparation for
714  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
715  glx.h, unistd.h and assert.h.
716
71724th August 2001  John Allison  (vis-V03-02-13)
718- Limited the printing of warnings in
719  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
720
72114th August 2001  John Allison  (vis-V03-02-11)
722- Improved KernelVisitDecision.
723- Fixed a few small bugs in multiple "stored" viewers, but see next item.
724- There's an outstanding bug in OpenGL Stored.  If there is more than
725  one viewer controlled by a scene handler, after a ClearStore on the
726  scene handler, e.g., with /vis/scene/notifyHandlers, the first
727  viewer to get refreshed should trigger the display list rebuild, but
728  the second need not.  However, when the second viewer's turn comes,
729  the display lists are there, and are called, e.g.,
730  G4OpenGLStoredXViewer::DrawView calls
731  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
732  nothing appears on the screen.  To overcome this there is some
733  temporary code in G4VViewer::NeedKernelVisit which marks *all*
734  viewers to force a rebuild.  To see the symptoms, comment out that
735  temporary code and issue these commands:
736    /vis/verbose c
737    /control/verbose 2
738    /vis/scene/create
739    /vis/scene/add/volume
740    /vis/sceneHandler/create OGLSX
741    /vis/viewer/create ! ! 1
742    /run/beamOn
743    /vis/viewer/create ! ! 1
744    /vis/viewer/select viewer-0
745    /vis/viewer/viewpointThetaPhi 20 20
746    /vis/viewer/select viewer-1
747    /vis/viewer/viewpointThetaPhi 40 40
748    /vis/viewer/set/style surface
749    /vis/viewer/refresh
750    /vis/viewer/select viewer-0
751    /vis/viewer/refresh
752    /vis/viewer/select viewer-1
753    /vis/viewer/set/style wireframe
754    /vis/scene/notifyHandlers
755  You may have to do this too:
756    /vis/viewer/select viewer-0
757    /vis/scene/notifyHandlers
758  One of the viewers is empty.  Curious!!
759
7609th August 2001  John Allison  (vis-V03-02-10-00)
761- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
762- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
763  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
764  picked up by inheritance anyway.
765- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
766- Corrected order of calling base class functions in
767  G4OpenGLStoredSceneHandler::Begin/EndModeling.
768
76924th July 2001  John Allison  (vis-V03-02-06)
770- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
771
77214th July 2001  John Allison (opengl-V03-02-00)
773- Fixed crash in optimised mode: added Initialise() to viewers so
774  that windows are opened after viewers are fully constructed.
775
7762nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
777- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
778
7797th March 2001  John Allison
780- Changed char* to const char* in many places and that gave problems in
781  calls to Xt and Xm.  Hope all's OK.  Differences:
782    cvs diff -r vis-V03-00-06 vis-V03-00-07
783
78425th January 2001  John Allison  (opengl-V03-00-00)
785- Implemented running re-calculation of up-vector in the case of "object
786  rotation" (lights move with camera) to prevent "flipping" of view when
787  camera passes through up-vector.  Note that the default is "camera
788  rotation" (lights do not move with camera, i.e., remain fixed relative
789  to object) so the default is that this "flipping" can happen.  To set
790  "object rotation" (lights move with camera) use
791  /vis/lights/move_with_camera true (soon to be
792  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
793  on Rotation Panel in OpenGLXm mode.
794- Changed some objects to references for efficiency.  E.g.:
795  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
796
79722nd May 2000  John Allison  (opengl-V01-01-00)
798- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
799  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
800    static XVisualInfo* vi_single_buffer;
801    static XVisualInfo* vi_double_buffer;
802- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
803  G4OpenGLXViewer.
804- Protected double deletion of window in destructors of G4OpenGLXmViewer
805  and G4OpenGLXViewer (Guy Barrand).
806- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
807- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
808  constructors.
Note: See TracBrowser for help on using the repository browser.
