269- Bug fixes:
270 o Correct path /vis/ogl/set/printMode.
271 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
272 and "/vis/ogl/printEPS").
273
2748th May 2007 John Allison (opengl-V08-02-06)
275- Moved vectored PostScript printing to G4OpenGLViewer.
276- /vis/ogl/printEPS should work for all viewers, including Win32.
277- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
278 effective on X windows (and still somewhat buggy).
279
2804th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
281- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
282 for OGL*Win32. Still doesn't work for OGL*Xm.
283
2843rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
285- G4OpenGLStoredSceneHandler:
286 o Re-organised display lists on a per-primitive basis, i.e., one
287 display list per primitive. (This is so that, except for text,
288 the colour - or, rather, intensity - can be brought out of the
289 display list into the TOList (Transient Object List) and
290 controlled for the Display-by-Time feature. Previously, if more
291 than one primitive were drawn between BeginPrimitives and
292 EndPrimitives, it would finish up all in one display list, colour
293 commands included. Rationalises and fixes a rare bug in the
294 Display-by-Time feature - see August 2006.)
295 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
296 one primoitive to fit with the above re-organisation.
297- Implemented picking for OGLIX.
298
29925th March 2007 John Allison (opengl-V08-02-03)
300- Fix compiler warnings.
301
3028th February 2007 John Allison (opengl-V08-02-02)
303- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
304- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
305 .but not switched back. Not serious, because context was always set
306 before normal drawing.)
307
3089th January 2007 John Allison (opengl-V08-02-01)
309- Implemented bitmap markers for MarkerSizeType == screen. (The old
310 polygon implementation remains for MarkerSizeType == world.)
311- Added G4OpenGLBitMapStore to assist the above.
312- G4OpenGLXViewer::CreateGLXContext:
313 o Bug fix: Added missing break in colormap lookup routine.
314
3155th January 2007 John Allison (opengl-V08-02-00)
316- G4OpenGLSceneHandler.cc:
317 o Followed change of signature of GetLineWidth in visman-V08-02-00.
318 o Minor efficiency improvements.
319
32021st November 2006 John Allison (opengl-V08-01-09)
321- Fixed compiler warnings.
322
3231st November 2006 John Allison (opengl-V08-01-08)
324- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
325 actually initiates a print, rather than set a flag for printing.
326
32724th October 2006 John Allison (opengl-V08-01-07)
328- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
329- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
330
33119th September 2006 John Allison (opengl-V08-01-06)
332- Added time origin for light front.
333- Added /vis/ogl/set/transparency.
334- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
335
3364th September 2006 John Allison (opengl-V08-01-05)
337- Implement cutaways.
338- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
339 primitives (see detector being drawn).
340- /vis/oglx/set/printEPS: change parameter default to true.
341
34230th August 2006 John Allison (opengl-V08-01-04)
343- G4OpenGLSceneHandler:
344 o Implemented line width.
345 o Switched off back face culling when clipping so that the inside of
346 volumes can be seen.
347 o Added CreateSection/CutawayPolyhedron to exploit generic
348 sectioning (DCUT) and cutaways. Currently not activated due to
349 instabilities in BooleanProcessor. Local sectioning still active
350 but broken (at least on Mac) due to apparent change in effect of
351 clipping planes (polyhedron edges not reconstructed).
352 o Rationalised calculation of marker size.
353- G4OpenGLStoredSceneHandler:
354 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
355 o Pick up time range from G4VisAttributes.
356- G4OpenGLViewer(Messenger):
357 o Added position and colour to /vis/ogl/set/displayHeadTime.
358 o Added /vis/ogl/set/displayLightFront.
359- G4OpenGLStoredViewer.cc:
360 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
361 o Added position and colour to DisplayHeadTime.
362 o Added DisplayLightFront.
363
36416th August 2006 John Allison (opengl-V08-01-03)
365- Corrected Solaris compilation error.
366- Added /vis/ogl/set/fade and displayHeadTime.
367
36814th August 2006 John Allison (opengl-V08-01-02)
369- Needs visman-V08-01-02.
370- G4OpenGLStored: Implemented display-by-time. Only available in
371 stored mode at present. Only implemented for circle, square,
372 polyline and polymarker at present, enough for currently available
373 trajectory models. Time is communicated via G4AttValues.
374- Added G4OpenGLViewerMessenger.
375- Added /vis/ogl/set/startTime and endTime of displayed objects.
376- All factories: Instantiated G4OpenGLViewerMessenger.
377- G4OpenGLViewer: Added fStart/EndTime.
378- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
379 spewPrimitiveEPS and spewSortedFeedback.
380
38117th July John Allison (opengl-V08-01-01)
382- Added /vis/oglx/set/printEPS (prints eps file on every update).
383
3843rd July 2006 John Allison (opengl-V08-01-00)
385- Elimination of redundant variable doublebuffer and implementation of
386 FinishView in all viewers.
387
38830th May 2006 Joseph Perl (opengl-V08-00-08)
389- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
390 variable seems to have random behavior and should be assumed false for
391 this viewer.
392
39329th May 2006 Joseph Perl (opengl-V08-00-07)
394- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
395 Removed common FinishView and instead made separate FinishView for the two different
396 versions of this viewer since each wants a different buffer swapping behaviour.
397
39812th May 2006 John Allison (opengl-V08-00-06)
399- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
400
40128th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
402- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
403 recomputing transients.
404
40524th April 2006 John Allison (opengl-V08-00-04)
406- Fixed compilation problem on Windows.
407
40819th April 2006 John Allison (opengl-V08-00-03)
409- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
410 G4OpenGLImmediateSceneHandler:
411 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
412 greps-V08-00-02).
413 o Migrated to direct access to G4PhysicalVolumeModel.
414- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
415 of display lists in DrawView.
416
41714th March 2006 John Allison (opengl-V08-00-02)
418- Refined display list building and re-drawing algorithm.
419 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
420 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
421- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
422 re-use algorithm. In test19 with global culling off, numbers of
423 display lists used are:
424 o 191 No re-use:
425 o 73 Before this change: re-use except replicas (includes parameterised).
426 o 33 After this change: re-use except parameterised and replicas in radius.
427
42826th January 2006 John Allison (opengl-V08-00-01)
429- Coworks with visman-V08-00-04 (removed fModified).
430- Removed references to fModified.
431- Tidying: Removed unnecessary ClearView.
432- G4OpenGLSceneHandler.cc: Added some (commented out) code for
433 possible future implementation of 2D drawing.

435
43611th January 2006 John Allison (opengl-V08-00-00)
437- Improved efficiency: all DrawView's:
438 o Don't call ClearView.
439 o Set flag so SetView will not be called in ProcessView.
440 o Leave background colour to ClearView.
441- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
442- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
443 for current viewer.
444
44524th November 2005 John Allison (opengl-V07-01-09)

466 scene handler.
467- Re-implemented transparency button in OpenGLXm.
468
46913th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
470- Implemented white background for all OGL viewers.
471- G4OpenGLSceneHandler.cc:
472 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
473 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
474 o Corrected GetTextColour(text).
475 o Corrected GetColour(polyhedron).
476
4775th September 2005 John Allison (opengl-V07-01-03)
478- Bug fix: stored transparent objects were being lost.
479
4802nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
481- Bug fix: edgeflags problem introduced with smooth shading in
482 opengl-V07-01-00.
483- Implementation of a "better algorithm" for the rendering of
484 transparent polyhedron objects. It renders all opaque objects
485 first, then renders the transparent objects with the depth buffer in
486 read-only mode (see OpenGL Programming Guide). It uses the new
487 facility in G4VSceneHandler::ProcessScene for an optional second pass
488 of the run-duration models in the scene. Note this algorithm is
489 still only an approximation. It will still give the wrong blended
490 colour if two transparent objects are rendered front first. For
491 nested transparent objects, this is unfortunate, because
492 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
493 in such a way that mothers come first. Also, there is no guaranteed
494 relationship between the order of rendering and the depth of two
495 transparent objects if they are at the same level or in different
496 branches of the hierarchy. Still, the only error will be an
497 incorrect colour - the objects will still give the appearance of
498 transparency, so it's a pretty good algorithm. (An even better
499 algorithm would be to attempt to render the facets in depth order,
500 deepest first. But how do you calculate the depth - centre of area,
501 deepest corner? One can still imagine pathalogical cases that would
502 sometimes give the wrong colour. Also, for stored mode, the order
503 is fixed in a display list so when the user rotates the view, one
504 would lose the depth ordering. I think we have to accept that
505 blending in OpenGL is only ever an approximation. For accurate
506 blending, use RayTracer.)
507
50828th August 2005 John Allison (opengl-V07-01-01)
509- Half-way implementation of rendering of transparent polyhedron
510 objects. In this implementation, no account is taken of the order
511 of rendering. Transparent objects are rendered with depth testing
512 off so that objects behind can still be seen. But this means that
513 opaque objects in front do not obscure them - and they jolly well
514 should! A better algorithm is to render all opaque objects first,
515 then render the transparent objects with the depth buffer in
516 read-only mode (see OpenGL Programming Guide). This is going to
517 take a little more thought - see opengl-V07-01-02.
518
51920th July 2005 John Allison (opengl-V07-01-00)
520- Introduced smooth shading, taking advantage of hitherto un-noticed
521 feature of HepPolyhedron::GetNextFacet that calculates the normals
522 at each vertex so that curved surfaces are rendered more
523 realistically (Gouraud shading).
524- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
525- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
526 the default window size. It used to be 400x400, hardcoded in
527 G4OpenGLXmViewer.cc, but now it picks up the
528 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
529 The user may change it on the command line, e.g:
530 /vis/open OGLSXm 500
531 or
532 /vis/viewer/create ! ! 500
533
53430th May 2005 John Allison (opengl-V07-00-03)
535- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
536 map of vectors in G4OpenGLFontBaseStore.)
537
5384th May 2005 John Allison (opengl-V07-00-02)
539- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
540 was taken out to prevent recursive calling, but that seems to be OK,
541 and it is needed to implement refresh at end of event/run.)
542
54322nd April 2005 John Allison (opengl-V07-00-01)
544- Rationalised work of opengl-V07-00-00. Functionality unchanged.
545 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
546 o In all concrete viewers, added call to CreateFontLists().
547 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
548 o There is no longer a need to implement in the XmViewer, since it
549 now inherits. Thus the font code now only appears once for X.
550 o Awaiting implementation for WIN32.
551
55217th April 2005 John Allison (opengl-V07-00-00)
553- Based on vis-V07-00-13.
554- Implemented text for X-Windows viewers. Uses glXUseXFont, which
555 creates display lists for nominated fonts. Simple-minded scheme in
556 which each viewer creates its own font display lists for a variety
557 of sizes, which are accessed by the scene handler through a new
558 class, G4OpenGLFontBaseStore. Affected methods:
559 G4OpenGLXViewer::CreateMainWindow()
560 G4OpenGLXmViewer::CreateMainWindow()
561 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
562
56318th November 2004 John Allison (opengl-V06-02-07)
564- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
565
56615th November 2004 Guy Barrand
567- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
568 to see trajectories (for example with N03). Correct so that
569 ShowView do a FinishView that does : glFlush, wglSwapBuffer
570 and empty the Windows message queue.
571
57222nd September 2004 John Allison (opengl-V06-02-06)
573- doxygen output to tmp area.
574- Trap non-regular polyhedrons.
575
57613th September 2004 Gabriele Cosmo (opengl-V06-02-05)
577- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
578 to allow for porting on CLHEP-1.9.X series.
579
58023rd July 2004 John Allison
581- Draws auxiliary edges if required.
582- Added auxiliary edge button.
583
58416th July 2004 John Allison (opengl-V06-02-04)
585- Refinements to hidden line, hidden surface removal.
586
58714th July 2004 John Allison (opengl-V06-02-03)
588- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
589
59013th July 2004 John Allison (opengl-V06-02-02)
591- Hidden line *and* hidden surface removal now works.
592
5939th July 2004 John Allison (opengl-V06-02-01)
594- Fixed long-standing problem with hidden line removal.
595- Improved messages on failure to get visual.
596- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
597 systems provided by default anyway, so no effect.
598
5991st July 2004 John Allison (opengl-V06-02-00)
600- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
601- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
602
60318th June 2004 Gunter Folger (geant4-06-02)
6049th June 2004 Gabriele Cosmo (vis-V06-01-03)
6057th June 2004 Gabriele Cosmo (vis-V06-01-02)
606- GNUmakefile and disclaimer changes - see visualization/History.
607
6089th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
609- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
610
6117th April 2004 Guy Barrand
612- visualization/OpenGL/* : use the G4OpenGL.hh file.
613- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
614 the include of gl/gl.h and gl/glu.h that may be platform dependant.
615 It permits to rm some #ifdef WIN32 spread in the code. It opens also
616 the way to the usage of the Apple OpenGL on a Mac.
617
61817th February 2004 John Allison (opengl-V06-00-00)
619- Fixed bug #581: wrong order of statements in
620 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
621
6224th October 2003 Gabriele Cosmo (vis-V05-02-01)
623- GNUmakefile:
624 o replaced "digits+hits" with "digits_hits".
625- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
626
62722nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
628- Cosmetic change to regularise names:
629 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
630 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
631
63223rd June 2003 Guy Barrand (opengl-V05-01-02)
633- Commit a first implementation of G4OpenGLWin32Viewer.
634
63510th June 2003 Gabriele Cosmo (opengl-V05-01-01)
636- More fixes for warnings in viewers classes.
637- Added inclusion of <windows.h> for WIN32 platforms when GL headers
638 are included.
639
64005th June 2003 Gabriele Cosmo (opengl-V05-01-00)
641- Fixes for porting compilation on WIN32:
642 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
643 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
644 since declared 'obsolete' in WIN32 platforms.
645
64627th November 2002 John Allison (vis-V04-01-08)
647- Improved algorithm of CompareForKernelVisit.
648
64911th November 2002 John Allison (opengl-V04-01-02)
650- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
651- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
652 call default but there as a marker and encourager.
653- Added tracking and digits+hits/hits to GNUmakefile.
654
65516th October 2002 John Allison (opengl-V04-01-01)
656- Fix for WIN32. Now compiles but viewer not implemented.
657
65824th June 2002 John Allison (opengl-V04-01-00)
659- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
660
66110th June 2002 John Allison (opengl-V04-00-03)
662- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
663
6646th June 2002 John Allison (opengl-V04-00-02)
665- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
666
66723rd February 2002 John Allison (opengl-V04-00-01)
668- Changes to encourage compilation on Windows in preparation for
669 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
670 glx.h, unistd.h and assert.h.
671
67224th August 2001 John Allison (vis-V03-02-13)
673- Limited the printing of warnings in
674 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
675
67614th August 2001 John Allison (vis-V03-02-11)
677- Improved KernelVisitDecision.
678- Fixed a few small bugs in multiple "stored" viewers, but see next item.
679- There's an outstanding bug in OpenGL Stored. If there is more than
680 one viewer controlled by a scene handler, after a ClearStore on the
681 scene handler, e.g., with /vis/scene/notifyHandlers, the first
682 viewer to get refreshed should trigger the display list rebuild, but
683 the second need not. However, when the second viewer's turn comes,
684 the display lists are there, and are called, e.g.,
685 G4OpenGLStoredXViewer::DrawView calls
686 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
687 nothing appears on the screen. To overcome this there is some
688 temporary code in G4VViewer::NeedKernelVisit which marks *all*
689 viewers to force a rebuild. To see the symptoms, comment out that
690 temporary code and issue these commands:
691 /vis/verbose c
692 /control/verbose 2
693 /vis/scene/create
694 /vis/scene/add/volume
695 /vis/sceneHandler/create OGLSX
696 /vis/viewer/create ! ! 1
697 /run/beamOn
698 /vis/viewer/create ! ! 1
699 /vis/viewer/select viewer-0
700 /vis/viewer/viewpointThetaPhi 20 20
701 /vis/viewer/select viewer-1
702 /vis/viewer/viewpointThetaPhi 40 40
703 /vis/viewer/set/style surface
704 /vis/viewer/refresh
705 /vis/viewer/select viewer-0
706 /vis/viewer/refresh
707 /vis/viewer/select viewer-1
708 /vis/viewer/set/style wireframe
709 /vis/scene/notifyHandlers
710 You may have to do this too:
711 /vis/viewer/select viewer-0
712 /vis/scene/notifyHandlers
713 One of the viewers is empty. Curious!!
714
7159th August 2001 John Allison (vis-V03-02-10-00)
716- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
717- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
718 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
719 picked up by inheritance anyway.
720- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
721- Corrected order of calling base class functions in
722 G4OpenGLStoredSceneHandler::Begin/EndModeling.
723
72424th July 2001 John Allison (vis-V03-02-06)
725- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
726
72714th July 2001 John Allison (opengl-V03-02-00)
728- Fixed crash in optimised mode: added Initialise() to viewers so
729 that windows are opened after viewers are fully constructed.
730
7312nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
732- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
733
7347th March 2001 John Allison
735- Changed char* to const char* in many places and that gave problems in
736 calls to Xt and Xm. Hope all's OK. Differences:
737 cvs diff -r vis-V03-00-06 vis-V03-00-07
738
73925th January 2001 John Allison (opengl-V03-00-00)
740- Implemented running re-calculation of up-vector in the case of "object
741 rotation" (lights move with camera) to prevent "flipping" of view when
742 camera passes through up-vector. Note that the default is "camera
743 rotation" (lights do not move with camera, i.e., remain fixed relative
744 to object) so the default is that this "flipping" can happen. To set
745 "object rotation" (lights move with camera) use
746 /vis/lights/move_with_camera true (soon to be
747 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
748 on Rotation Panel in OpenGLXm mode.
749- Changed some objects to references for efficiency. E.g.:
750 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
751
75222nd May 2000 John Allison (opengl-V01-01-00)
753- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
754 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
755 static XVisualInfo* vi_single_buffer;
756 static XVisualInfo* vi_double_buffer;
757- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
758 G4OpenGLXViewer.
759- Protected double deletion of window in destructors of G4OpenGLXmViewer
760 and G4OpenGLXViewer (Guy Barrand).
761- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
762- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
763 constructors.
Note: See TracBrowser for help on using the repository browser.
