255  o Correct path /vis/ogl/set/printMode.
256  o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
257    and "/vis/ogl/printEPS").
258
2598th May 2007  John Allison  (opengl-V08-02-06)
260- Moved vectored PostScript printing to G4OpenGLViewer.
261- /vis/ogl/printEPS should work for all viewers, including Win32.
262- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
263  effective on X windows (and still somewhat buggy).
264
2654th April 2007  John Allison  (opengl-V08-02-05 - needs visman-V08-02-04)
266- Implemented picking for OGLSX ( as well as OGLIX).  Hopefully works
267  for OGL*Win32.  Still doesn't work for OGL*Xm.
268
2693rd April 2007  John Allison  (opengl-V08-02-04 - needs visman-V08-02-03)
270- G4OpenGLStoredSceneHandler:
271  o Re-organised display lists on a per-primitive basis, i.e., one
272    display list per primitive.  (This is so that, except for text,
273    the colour - or, rather, intensity - can be brought out of the
274    display list into the TOList (Transient Object List) and
275    controlled for the Display-by-Time feature.  Previously, if more
276    than one primitive were drawn between BeginPrimitives and
277    EndPrimitives, it would finish up all in one display list, colour
278    commands included. Rationalises and fixes a rare bug in the
279    Display-by-Time feature - see August 2006.)
280  o Added AddPrimitive(const G4Polymarker&) so that it is treated as
281    one primoitive to fit with the above re-organisation.
282- Implemented picking for OGLIX.
283
28425th March 2007  John Allison  (opengl-V08-02-03)
285- Fix compiler warnings.
286
2878th February 2007  John Allison  (opengl-V08-02-02)
288- Fixed Windows problem with DBL_MAX.  (Introduced G4OPENGL_DBL_MAX.)
289- G4OpenGLXViewer.cc: Small bug fix in print().  (Context was switched
290  .but not switched back.  Not serious, because context was always set
291  before normal drawing.)
292
2939th January 2007  John Allison  (opengl-V08-02-01)
294- Implemented bitmap markers for MarkerSizeType == screen.  (The old
295  polygon implementation remains for MarkerSizeType == world.)
296- Added G4OpenGLBitMapStore to assist the above.
297- G4OpenGLXViewer::CreateGLXContext:
298  o Bug fix: Added missing break in colormap lookup routine.
299
3005th January 2007  John Allison  (opengl-V08-02-00)
301- G4OpenGLSceneHandler.cc:
302  o Followed change of signature of GetLineWidth in visman-V08-02-00.
303  o Minor efficiency improvements.
304
30521st November 2006  John Allison  (opengl-V08-01-09)
306- Fixed compiler warnings.
307
3081st November 2006  John Allison  (opengl-V08-01-08)
309- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS.  The new command
310  actually initiates a print, rather than set a flag for printing.
311
31224th October 2006  John Allison  (opengl-V08-01-07)
313- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
314- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
315
31619th September 2006  John Allison  (opengl-V08-01-06)
317- Added time origin for light front.
318- Added /vis/ogl/set/transparency.
319- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
320
3214th September 2006  John Allison  (opengl-V08-01-05)
322- Implement cutaways.
323- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
324  primitives (see detector being drawn).
325- /vis/oglx/set/printEPS: change parameter default to true.
326
32730th August 2006  John Allison  (opengl-V08-01-04)
328- G4OpenGLSceneHandler:
329  o Implemented line width.
330  o Switched off back face culling when clipping so that the inside of
331    volumes can be seen.
332  o Added CreateSection/CutawayPolyhedron to exploit generic
333    sectioning (DCUT) and cutaways.  Currently not activated due to
334    instabilities in BooleanProcessor.  Local sectioning still active
335    but broken (at least on Mac) due to apparent change in effect of
336    clipping planes (polyhedron edges not reconstructed).
337  o Rationalised calculation of marker size.
338- G4OpenGLStoredSceneHandler:
339  o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
340  o Pick up time range from G4VisAttributes.
341- G4OpenGLViewer(Messenger):
342  o Added position and colour to /vis/ogl/set/displayHeadTime.
343  o Added /vis/ogl/set/displayLightFront.
344- G4OpenGLStoredViewer.cc:
345  o Rationalised CompareForKernelVisit.  (Local sectioning still active.)
346  o Added position and colour to DisplayHeadTime.
347  o Added DisplayLightFront.
348 
34916th August 2006  John Allison  (opengl-V08-01-03)
350- Corrected Solaris compilation error.
351- Added /vis/ogl/set/fade and displayHeadTime.
352
35314th August 2006  John Allison  (opengl-V08-01-02)
354- Needs visman-V08-01-02.
355- G4OpenGLStored: Implemented display-by-time.  Only available in
356  stored mode at present.  Only implemented for circle, square,
357  polyline and polymarker at present, enough for currently available
358  trajectory models.  Time is communicated via G4AttValues.
359- Added G4OpenGLViewerMessenger.
360- Added /vis/ogl/set/startTime and endTime of displayed objects.
361- All factories: Instantiated G4OpenGLViewerMessenger.
362- G4OpenGLViewer: Added fStart/EndTime.
363- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
364  spewPrimitiveEPS and spewSortedFeedback.
365
36617th July  John Allison  (opengl-V08-01-01)
367- Added /vis/oglx/set/printEPS (prints eps file on every update).
368
3693rd July 2006  John Allison  (opengl-V08-01-00)
370- Elimination of redundant variable doublebuffer and implementation of
371  FinishView in all viewers.
372
37330th May 2006  Joseph Perl  (opengl-V08-00-08)
374- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
375  variable seems to have random behavior and should be assumed false for
376  this viewer.
377
37829th May 2006  Joseph Perl  (opengl-V08-00-07)
379- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
380  Removed common FinishView and instead made separate FinishView for the two different
381  versions of this viewer since each wants a different buffer swapping behaviour.
382
38312th May 2006  John Allison  (opengl-V08-00-06)
384- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
385
38628th April 2006  John Allison  (opengl-V08-00-05 - needs visman-V08-00-14)
387- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
388  recomputing transients.
389
39024th April 2006  John Allison  (opengl-V08-00-04)
391- Fixed compilation problem on Windows.
392
39319th April 2006  John Allison  (opengl-V08-00-03)
394- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
395  G4OpenGLImmediateSceneHandler:
396  o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
397    greps-V08-00-02).
398  o Migrated to direct access to G4PhysicalVolumeModel.
399- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
400  of display lists in DrawView.
401
40214th March 2006  John Allison  (opengl-V08-00-02)
403- Refined display list building and re-drawing algorithm.
404  o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
405  o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
406- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
407  re-use algorithm.  In test19 with global culling off, numbers of
408  display lists used are:
409  o 191  No re-use:
410  o  73  Before this change: re-use except replicas (includes parameterised).
411  o  33  After this change: re-use except parameterised and replicas in radius.
412
41326th January 2006  John Allison  (opengl-V08-00-01)
414- Coworks with visman-V08-00-04 (removed fModified).

420
42111th January 2006  John Allison  (opengl-V08-00-00)
422- Improved efficiency: all DrawView's:
423  o Don't call ClearView.
424  o Set flag so SetView will not be called in ProcessView.
425  o Leave background colour to ClearView.
426- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
427- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
428  for current viewer.
429
43024th November 2005  John Allison  (opengl-V07-01-09)

442- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
443
44413th October 2005  John Allison  (opengl-V07-01-06)
445- Allowed any colour background.
446- Implemented non-uniform scaling.
447- Migration to <sstream>.
448
44929th September 2005  John Allison  (opengl-V07-01-05)
450- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
451  scene handler.
452- Re-implemented transparency button in OpenGLXm.
453
45413th September 2005  John Allison  (opengl-V07-01-04 - needs visman-V07-01-02)
455- Implemented white background for all OGL viewers.
456- G4OpenGLSceneHandler.cc:
457  o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
458  o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
459  o Corrected GetTextColour(text).
460  o Corrected GetColour(polyhedron).
461
4625th September 2005  John Allison  (opengl-V07-01-03)
463- Bug fix: stored transparent objects were being lost.
464
4652nd September 2005  John Allison  (opengl-V07-01-02 - needs visman-V07-01-01)
466- Bug fix: edgeflags problem introduced with smooth shading in
467  opengl-V07-01-00.
468- Implementation of a "better algorithm" for the rendering of
469  transparent polyhedron objects.  It renders all opaque objects
470  first, then renders the transparent objects with the depth buffer in
471  read-only mode (see OpenGL Programming Guide).  It uses the new
472  facility in G4VSceneHandler::ProcessScene for an optional second pass
473  of the run-duration models in the scene.  Note this algorithm is
474  still only an approximation.  It will still give the wrong blended
475  colour if two transparent objects are rendered front first.  For
476  nested transparent objects, this is unfortunate, because
477  G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
478  in such a way that mothers come first.  Also, there is no guaranteed
479  relationship between the order of rendering and the depth of two
480  transparent objects if they are at the same level or in different
481  branches of the hierarchy.  Still, the only error will be an
482  incorrect colour - the objects will still give the appearance of
483  transparency, so it's a pretty good algorithm.  (An even better
484  algorithm would be to attempt to render the facets in depth order,
485  deepest first.  But how do you calculate the depth - centre of area,
486  deepest corner?  One can still imagine pathalogical cases that would
487  sometimes give the wrong colour.  Also, for stored mode, the order
488  is fixed in a display list so when the user rotates the view, one
489  would lose the depth ordering.  I think we have to accept that
490  blending in OpenGL is only ever an approximation.  For accurate
491  blending, use RayTracer.)
492
49328th August 2005  John Allison  (opengl-V07-01-01)
494- Half-way implementation of rendering of transparent polyhedron
495  objects.  In this implementation, no account is taken of the order
496  of rendering.  Transparent objects are rendered with depth testing
497  off so that objects behind can still be seen.  But this means that
498  opaque objects in front do not obscure them - and they jolly well
499  should!  A better algorithm is to render all opaque objects first,
500  then render the transparent objects with the depth buffer in
501  read-only mode (see OpenGL Programming Guide).  This is going to
502  take a little more thought - see opengl-V07-01-02.
503
50420th July 2005  John Allison  (opengl-V07-01-00)
505- Introduced smooth shading, taking advantage of hitherto un-noticed
506  feature of HepPolyhedron::GetNextFacet that calculates the normals
507  at each vertex so that curved surfaces are rendered more
508  realistically (Gouraud shading).
509- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
510- G4OpenGLXmViewer.cc: Fixed to use window size hints.  This changes
511  the default window size.  It used to be 400x400, hardcoded in
512  G4OpenGLXmViewer.cc, but now it picks up the
513  G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
514  The user may change it on the command line, e.g:
515    /vis/open OGLSXm 500
516  or
517    /vis/viewer/create ! ! 500
518
51930th May 2005  John Allison  (opengl-V07-00-03)
520- Fixed compilation problem in OpenGL on SUN.  (Replaced multimap by
521  map of vectors in G4OpenGLFontBaseStore.)
522
5234th May 2005  John Allison  (opengl-V07-00-02)
524- Restored sequence Set/Clear/DrawView in ClearTransientStore.  (It
525  was taken out to prevent recursive calling, but that seems to be OK,
526  and it is needed to implement refresh at end of event/run.)
527
52822nd April 2005  John Allison  (opengl-V07-00-01)
529- Rationalised work of opengl-V07-00-00.  Functionality unchanged.
530  o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
531  o In all concrete viewers, added call to CreateFontLists().
532  o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
533  o There is no longer a need to implement in the XmViewer, since it
534    now inherits.  Thus the font code now only appears once for X.
535  o Awaiting implementation for WIN32.
536
53717th April 2005  John Allison  (opengl-V07-00-00)
538- Based on vis-V07-00-13.
539- Implemented text for X-Windows viewers.  Uses glXUseXFont, which
540  creates display lists for nominated fonts.  Simple-minded scheme in
541  which each viewer creates its own font display lists for a variety
542  of sizes, which are accessed by the scene handler through a new
543  class, G4OpenGLFontBaseStore.  Affected methods:
544    G4OpenGLXViewer::CreateMainWindow()
545    G4OpenGLXmViewer::CreateMainWindow()
546    G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
547
54818th November 2004  John Allison  (opengl-V06-02-07)
549- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
550
55115th November 2004  Guy Barrand
552- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
553  to see trajectories (for example with N03). Correct so that
554  ShowView do a FinishView that does : glFlush, wglSwapBuffer
555  and empty the Windows message queue.
556
55722nd September 2004  John Allison  (opengl-V06-02-06)
558- doxygen output to tmp area.
559- Trap non-regular polyhedrons.
560
56113th September 2004  Gabriele Cosmo  (opengl-V06-02-05)
562- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
563  to allow for porting on CLHEP-1.9.X series.
564
56523rd July 2004  John Allison
566- Draws auxiliary edges if required.
567- Added auxiliary edge button.
568
56916th July 2004  John Allison  (opengl-V06-02-04)
570- Refinements to hidden line, hidden surface removal.
571
57214th July 2004  John Allison  (opengl-V06-02-03)
573- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
574
57513th July 2004  John Allison  (opengl-V06-02-02)
576- Hidden line *and* hidden surface removal now works.
577
5789th July 2004  John Allison  (opengl-V06-02-01)
579- Fixed long-standing problem with hidden line removal.
580- Improved messages on failure to get visual.
581- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
582  systems provided by default anyway, so no effect.
583
5841st July 2004  John Allison  (opengl-V06-02-00)
585- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
586- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
587
58818th June 2004  Gunter Folger (geant4-06-02)
5899th June 2004  Gabriele Cosmo  (vis-V06-01-03)
5907th June 2004  Gabriele Cosmo  (vis-V06-01-02)
591- GNUmakefile and disclaimer changes - see visualization/History.
592
5939th April 2004  John Allison  (vis-V06-01-01 + interfaces-V06-01-00)
594- Tagged OpenGL as below.  Joint with interfaces-V06-01-00.
595
5967th April 2004  Guy Barrand
597- visualization/OpenGL/* : use the G4OpenGL.hh file.
598- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
599  the include of gl/gl.h and gl/glu.h that may be platform dependant.
600  It permits to rm some #ifdef WIN32 spread in the code. It opens also
601  the way to the usage of the Apple OpenGL on a Mac.
602
60317th February 2004  John Allison  (opengl-V06-00-00)
604- Fixed bug #581: wrong order of statements in
605  G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
606
6074th October 2003  Gabriele Cosmo  (vis-V05-02-01)
608- GNUmakefile:
609  o replaced "digits+hits" with "digits_hits".
610- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
611
61222nd September 2003  John Allison  (vis-V05-02-00, greps-V05-02-00)
613- Cosmetic change to regularise names:
614  o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
615  o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
616
61723rd June 2003  Guy Barrand  (opengl-V05-01-02)
618- Commit a first implementation of G4OpenGLWin32Viewer.
619
62010th June 2003  Gabriele Cosmo  (opengl-V05-01-01)
621- More fixes for warnings in viewers classes.
622- Added inclusion of <windows.h> for WIN32 platforms when GL headers
623  are included.
624
62505th June 2003  Gabriele Cosmo  (opengl-V05-01-00)
626- Fixes for porting compilation on WIN32:
627  o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
628  o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
629    since declared 'obsolete' in WIN32 platforms.
630
63127th November 2002  John Allison  (vis-V04-01-08)
632- Improved algorithm of CompareForKernelVisit.
633
63411th November 2002  John Allison  (opengl-V04-01-02)
635- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
636- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
637  call default but there as a marker and encourager.
638- Added tracking and digits+hits/hits to GNUmakefile.
639
64016th October 2002  John Allison  (opengl-V04-01-01)
641- Fix for WIN32.  Now compiles but viewer not implemented.
642
64324th June 2002  John Allison  (opengl-V04-01-00)
644- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
645
64610th June 2002  John Allison  (opengl-V04-00-03)
647- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
648
6496th June 2002  John Allison  (opengl-V04-00-02)
650- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
651
65223rd February 2002  John Allison  (opengl-V04-00-01)
653- Changes to encourage compilation on Windows in preparation for
654  implementation of G4OpenGLWin32Viewer.  Removed spurious includes of
655  glx.h, unistd.h and assert.h.
656
65724th August 2001  John Allison  (vis-V03-02-13)
658- Limited the printing of warnings in
659  G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
660
66114th August 2001  John Allison  (vis-V03-02-11)
662- Improved KernelVisitDecision.
663- Fixed a few small bugs in multiple "stored" viewers, but see next item.
664- There's an outstanding bug in OpenGL Stored.  If there is more than
665  one viewer controlled by a scene handler, after a ClearStore on the
666  scene handler, e.g., with /vis/scene/notifyHandlers, the first
667  viewer to get refreshed should trigger the display list rebuild, but
668  the second need not.  However, when the second viewer's turn comes,
669  the display lists are there, and are called, e.g.,
670  G4OpenGLStoredXViewer::DrawView calls
671  G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
672  nothing appears on the screen.  To overcome this there is some
673  temporary code in G4VViewer::NeedKernelVisit which marks *all*
674  viewers to force a rebuild.  To see the symptoms, comment out that
675  temporary code and issue these commands:
676    /vis/verbose c
677    /control/verbose 2
678    /vis/scene/create
679    /vis/scene/add/volume
680    /vis/sceneHandler/create OGLSX
681    /vis/viewer/create ! ! 1
682    /run/beamOn
683    /vis/viewer/create ! ! 1
684    /vis/viewer/select viewer-0
685    /vis/viewer/viewpointThetaPhi 20 20
686    /vis/viewer/select viewer-1
687    /vis/viewer/viewpointThetaPhi 40 40
688    /vis/viewer/set/style surface
689    /vis/viewer/refresh
690    /vis/viewer/select viewer-0
691    /vis/viewer/refresh
692    /vis/viewer/select viewer-1
693    /vis/viewer/set/style wireframe
694    /vis/scene/notifyHandlers
695  You may have to do this too:
696    /vis/viewer/select viewer-0
697    /vis/scene/notifyHandlers
698  One of the viewers is empty.  Curious!!
699
7009th August 2001  John Allison  (vis-V03-02-10-00)
701- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
702- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
703  invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
704  picked up by inheritance anyway.
705- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
706- Corrected order of calling base class functions in
707  G4OpenGLStoredSceneHandler::Begin/EndModeling.
708
70924th July 2001  John Allison  (vis-V03-02-06)
710- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
711
71214th July 2001  John Allison (opengl-V03-02-00)
713- Fixed crash in optimised mode: added Initialise() to viewers so
714  that windows are opened after viewers are fully constructed.
715
7162nd April 2001  John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
717- Tidied G4OpenGLXmViewer callback code.  Removed superfluous header files.
718
7197th March 2001  John Allison
720- Changed char* to const char* in many places and that gave problems in
721  calls to Xt and Xm.  Hope all's OK.  Differences:
722    cvs diff -r vis-V03-00-06 vis-V03-00-07
723
72425th January 2001  John Allison  (opengl-V03-00-00)
725- Implemented running re-calculation of up-vector in the case of "object
726  rotation" (lights move with camera) to prevent "flipping" of view when
727  camera passes through up-vector.  Note that the default is "camera
728  rotation" (lights do not move with camera, i.e., remain fixed relative
729  to object) so the default is that this "flipping" can happen.  To set
730  "object rotation" (lights move with camera) use
731  /vis/lights/move_with_camera true (soon to be
732  /vis/viewer/set/lights move-with-camera) or click "Object" radio button
733  on Rotation Panel in OpenGLXm mode.
734- Changed some objects to references for efficiency.  E.g.:
735  const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
736
73722nd May 2000  John Allison  (opengl-V01-01-00)
738- Fixed slow response of 2nd window of OpenGLXm.  Worked around Mesa bug
739  by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
740    static XVisualInfo* vi_single_buffer;
741    static XVisualInfo* vi_double_buffer;
742- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
743  G4OpenGLXViewer.
744- Protected double deletion of window in destructors of G4OpenGLXmViewer
745  and G4OpenGLXViewer (Guy Barrand).
746- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
747- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
748  constructors.
Note: See TracBrowser for help on using the repository browser.
