385 and "/vis/ogl/printEPS").
386
3878th May 2007 John Allison (opengl-V08-02-06)
388- Moved vectored PostScript printing to G4OpenGLViewer.
389- /vis/ogl/printEPS should work for all viewers, including Win32.
390- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
391 effective on X windows (and still somewhat buggy).
392
3934th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
394- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
395 for OGL*Win32. Still doesn't work for OGL*Xm.
396
3973rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
398- G4OpenGLStoredSceneHandler:
399 o Re-organised display lists on a per-primitive basis, i.e., one
400 display list per primitive. (This is so that, except for text,
401 the colour - or, rather, intensity - can be brought out of the
402 display list into the TOList (Transient Object List) and
403 controlled for the Display-by-Time feature. Previously, if more
404 than one primitive were drawn between BeginPrimitives and
405 EndPrimitives, it would finish up all in one display list, colour
406 commands included. Rationalises and fixes a rare bug in the
407 Display-by-Time feature - see August 2006.)
408 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
409 one primoitive to fit with the above re-organisation.
410- Implemented picking for OGLIX.
411
41225th March 2007 John Allison (opengl-V08-02-03)
413- Fix compiler warnings.
414
4158th February 2007 John Allison (opengl-V08-02-02)
416- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
417- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
418 .but not switched back. Not serious, because context was always set
419 before normal drawing.)
420
4219th January 2007 John Allison (opengl-V08-02-01)
422- Implemented bitmap markers for MarkerSizeType == screen. (The old
423 polygon implementation remains for MarkerSizeType == world.)
424- Added G4OpenGLBitMapStore to assist the above.
425- G4OpenGLXViewer::CreateGLXContext:
426 o Bug fix: Added missing break in colormap lookup routine.
427
4285th January 2007 John Allison (opengl-V08-02-00)
429- G4OpenGLSceneHandler.cc:
430 o Followed change of signature of GetLineWidth in visman-V08-02-00.
431 o Minor efficiency improvements.
432
43321st November 2006 John Allison (opengl-V08-01-09)
434- Fixed compiler warnings.
435
4361st November 2006 John Allison (opengl-V08-01-08)
437- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
438 actually initiates a print, rather than set a flag for printing.
439
44024th October 2006 John Allison (opengl-V08-01-07)
441- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

448
4494th September 2006 John Allison (opengl-V08-01-05)
450- Implement cutaways.
451- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
452 primitives (see detector being drawn).
453- /vis/oglx/set/printEPS: change parameter default to true.
454
45530th August 2006 John Allison (opengl-V08-01-04)
456- G4OpenGLSceneHandler:
457 o Implemented line width.
458 o Switched off back face culling when clipping so that the inside of
459 volumes can be seen.
460 o Added CreateSection/CutawayPolyhedron to exploit generic
461 sectioning (DCUT) and cutaways. Currently not activated due to
462 instabilities in BooleanProcessor. Local sectioning still active
463 but broken (at least on Mac) due to apparent change in effect of
464 clipping planes (polyhedron edges not reconstructed).
465 o Rationalised calculation of marker size.
466- G4OpenGLStoredSceneHandler:
467 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
468 o Pick up time range from G4VisAttributes.
469- G4OpenGLViewer(Messenger):
470 o Added position and colour to /vis/ogl/set/displayHeadTime.
471 o Added /vis/ogl/set/displayLightFront.
472- G4OpenGLStoredViewer.cc:
473 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
474 o Added position and colour to DisplayHeadTime.
475 o Added DisplayLightFront.
476
47716th August 2006 John Allison (opengl-V08-01-03)
478- Corrected Solaris compilation error.
479- Added /vis/ogl/set/fade and displayHeadTime.
480
48114th August 2006 John Allison (opengl-V08-01-02)
482- Needs visman-V08-01-02.
483- G4OpenGLStored: Implemented display-by-time. Only available in
484 stored mode at present. Only implemented for circle, square,
485 polyline and polymarker at present, enough for currently available
486 trajectory models. Time is communicated via G4AttValues.
487- Added G4OpenGLViewerMessenger.
488- Added /vis/ogl/set/startTime and endTime of displayed objects.
489- All factories: Instantiated G4OpenGLViewerMessenger.
490- G4OpenGLViewer: Added fStart/EndTime.
491- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
492 spewPrimitiveEPS and spewSortedFeedback.
493
49417th July John Allison (opengl-V08-01-01)
495- Added /vis/oglx/set/printEPS (prints eps file on every update).
496
4973rd July 2006 John Allison (opengl-V08-01-00)
498- Elimination of redundant variable doublebuffer and implementation of
499 FinishView in all viewers.
500
50130th May 2006 Joseph Perl (opengl-V08-00-08)
502- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
503 variable seems to have random behavior and should be assumed false for
504 this viewer.
505
50629th May 2006 Joseph Perl (opengl-V08-00-07)
507- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
508 Removed common FinishView and instead made separate FinishView for the two different
509 versions of this viewer since each wants a different buffer swapping behaviour.
510
51112th May 2006 John Allison (opengl-V08-00-06)
512- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
513
51428th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
515- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
516 recomputing transients.
517
51824th April 2006 John Allison (opengl-V08-00-04)
519- Fixed compilation problem on Windows.
520
52119th April 2006 John Allison (opengl-V08-00-03)
522- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
523 G4OpenGLImmediateSceneHandler:
524 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
525 greps-V08-00-02).
526 o Migrated to direct access to G4PhysicalVolumeModel.
527- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
528 of display lists in DrawView.
529
53014th March 2006 John Allison (opengl-V08-00-02)
531- Refined display list building and re-drawing algorithm.
532 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
533 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
534- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
535 re-use algorithm. In test19 with global culling off, numbers of
536 display lists used are:
537 o 191 No re-use:
538 o 73 Before this change: re-use except replicas (includes parameterised).
539 o 33 After this change: re-use except parameterised and replicas in radius.
540
54126th January 2006 John Allison (opengl-V08-00-01)
542- Coworks with visman-V08-00-04 (removed fModified).
543- Removed references to fModified.
544- Tidying: Removed unnecessary ClearView.
545- G4OpenGLSceneHandler.cc: Added some (commented out) code for
546 possible future implementation of 2D drawing.
547- G4OpenGLXViewer.cc: Improved exception printing.
548
54911th January 2006 John Allison (opengl-V08-00-00)
550- Improved efficiency: all DrawView's:
551 o Don't call ClearView.
552 o Set flag so SetView will not be called in ProcessView.
553 o Leave background colour to ClearView.
554- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
555- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
556 for current viewer.
557
55824th November 2005 John Allison (opengl-V07-01-09)
559- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
560
56122nd November 2005 John Allison (opengl-V07-01-08)
562- Added G4OpenGLXmViewerMessenger.
563- Corrected text position.
564- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
565
56617th November 2005 Gabriele Cosmo
567- Fixed settings of background style for WIN32 viewers.
568
56913th November 2005 John Allison (opengl-V07-01-07)
570- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
571
57213th October 2005 John Allison (opengl-V07-01-06)
573- Allowed any colour background.
574- Implemented non-uniform scaling.
575- Migration to <sstream>.
576
57729th September 2005 John Allison (opengl-V07-01-05)
578- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
579 scene handler.
580- Re-implemented transparency button in OpenGLXm.
581
58213th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
583- Implemented white background for all OGL viewers.
584- G4OpenGLSceneHandler.cc:
585 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
586 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
587 o Corrected GetTextColour(text).
588 o Corrected GetColour(polyhedron).
589
5905th September 2005 John Allison (opengl-V07-01-03)
591- Bug fix: stored transparent objects were being lost.
592
5932nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
594- Bug fix: edgeflags problem introduced with smooth shading in
595 opengl-V07-01-00.
596- Implementation of a "better algorithm" for the rendering of
597 transparent polyhedron objects. It renders all opaque objects
598 first, then renders the transparent objects with the depth buffer in
599 read-only mode (see OpenGL Programming Guide). It uses the new
600 facility in G4VSceneHandler::ProcessScene for an optional second pass
601 of the run-duration models in the scene. Note this algorithm is
602 still only an approximation. It will still give the wrong blended
603 colour if two transparent objects are rendered front first. For
604 nested transparent objects, this is unfortunate, because
605 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
606 in such a way that mothers come first. Also, there is no guaranteed
607 relationship between the order of rendering and the depth of two
608 transparent objects if they are at the same level or in different
609 branches of the hierarchy. Still, the only error will be an
610 incorrect colour - the objects will still give the appearance of
611 transparency, so it's a pretty good algorithm. (An even better
612 algorithm would be to attempt to render the facets in depth order,
613 deepest first. But how do you calculate the depth - centre of area,
614 deepest corner? One can still imagine pathalogical cases that would
615 sometimes give the wrong colour. Also, for stored mode, the order
616 is fixed in a display list so when the user rotates the view, one
617 would lose the depth ordering. I think we have to accept that
618 blending in OpenGL is only ever an approximation. For accurate
619 blending, use RayTracer.)
620
62128th August 2005 John Allison (opengl-V07-01-01)
622- Half-way implementation of rendering of transparent polyhedron
623 objects. In this implementation, no account is taken of the order
624 of rendering. Transparent objects are rendered with depth testing
625 off so that objects behind can still be seen. But this means that
626 opaque objects in front do not obscure them - and they jolly well
627 should! A better algorithm is to render all opaque objects first,
628 then render the transparent objects with the depth buffer in
629 read-only mode (see OpenGL Programming Guide). This is going to
630 take a little more thought - see opengl-V07-01-02.
631
63220th July 2005 John Allison (opengl-V07-01-00)
633- Introduced smooth shading, taking advantage of hitherto un-noticed
634 feature of HepPolyhedron::GetNextFacet that calculates the normals
635 at each vertex so that curved surfaces are rendered more
636 realistically (Gouraud shading).
637- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
638- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
639 the default window size. It used to be 400x400, hardcoded in
640 G4OpenGLXmViewer.cc, but now it picks up the
641 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
642 The user may change it on the command line, e.g:
643 /vis/open OGLSXm 500
644 or
645 /vis/viewer/create ! ! 500
646
64730th May 2005 John Allison (opengl-V07-00-03)
648- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
649 map of vectors in G4OpenGLFontBaseStore.)
650
6514th May 2005 John Allison (opengl-V07-00-02)
652- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
653 was taken out to prevent recursive calling, but that seems to be OK,
654 and it is needed to implement refresh at end of event/run.)
655
65622nd April 2005 John Allison (opengl-V07-00-01)
657- Rationalised work of opengl-V07-00-00. Functionality unchanged.
658 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
659 o In all concrete viewers, added call to CreateFontLists().
660 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
661 o There is no longer a need to implement in the XmViewer, since it
662 now inherits. Thus the font code now only appears once for X.
663 o Awaiting implementation for WIN32.
664
66517th April 2005 John Allison (opengl-V07-00-00)
666- Based on vis-V07-00-13.
667- Implemented text for X-Windows viewers. Uses glXUseXFont, which
668 creates display lists for nominated fonts. Simple-minded scheme in
669 which each viewer creates its own font display lists for a variety
670 of sizes, which are accessed by the scene handler through a new
671 class, G4OpenGLFontBaseStore. Affected methods:
672 G4OpenGLXViewer::CreateMainWindow()
673 G4OpenGLXmViewer::CreateMainWindow()
674 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
675
67618th November 2004 John Allison (opengl-V06-02-07)
677- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
678
67915th November 2004 Guy Barrand
680- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
681 to see trajectories (for example with N03). Correct so that
682 ShowView do a FinishView that does : glFlush, wglSwapBuffer
683 and empty the Windows message queue.
684
68522nd September 2004 John Allison (opengl-V06-02-06)
686- doxygen output to tmp area.
687- Trap non-regular polyhedrons.
688
68913th September 2004 Gabriele Cosmo (opengl-V06-02-05)
690- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
691 to allow for porting on CLHEP-1.9.X series.
692
69323rd July 2004 John Allison
694- Draws auxiliary edges if required.
695- Added auxiliary edge button.
696
69716th July 2004 John Allison (opengl-V06-02-04)
698- Refinements to hidden line, hidden surface removal.
699
70014th July 2004 John Allison (opengl-V06-02-03)
701- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
702
70313th July 2004 John Allison (opengl-V06-02-02)
704- Hidden line *and* hidden surface removal now works.
705
7069th July 2004 John Allison (opengl-V06-02-01)
707- Fixed long-standing problem with hidden line removal.
708- Improved messages on failure to get visual.
709- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
710 systems provided by default anyway, so no effect.
711
7121st July 2004 John Allison (opengl-V06-02-00)
713- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
714- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
715
71618th June 2004 Gunter Folger (geant4-06-02)
7179th June 2004 Gabriele Cosmo (vis-V06-01-03)
7187th June 2004 Gabriele Cosmo (vis-V06-01-02)
719- GNUmakefile and disclaimer changes - see visualization/History.
720
7219th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
722- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
723
7247th April 2004 Guy Barrand
725- visualization/OpenGL/* : use the G4OpenGL.hh file.
726- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
727 the include of gl/gl.h and gl/glu.h that may be platform dependant.
728 It permits to rm some #ifdef WIN32 spread in the code. It opens also
729 the way to the usage of the Apple OpenGL on a Mac.
730
73117th February 2004 John Allison (opengl-V06-00-00)
732- Fixed bug #581: wrong order of statements in
733 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
734
7354th October 2003 Gabriele Cosmo (vis-V05-02-01)
736- GNUmakefile:
737 o replaced "digits+hits" with "digits_hits".
738- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
739
74022nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
741- Cosmetic change to regularise names:
742 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
743 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
744
74523rd June 2003 Guy Barrand (opengl-V05-01-02)
746- Commit a first implementation of G4OpenGLWin32Viewer.
747
74810th June 2003 Gabriele Cosmo (opengl-V05-01-01)
749- More fixes for warnings in viewers classes.
750- Added inclusion of <windows.h> for WIN32 platforms when GL headers
751 are included.
752
75305th June 2003 Gabriele Cosmo (opengl-V05-01-00)
754- Fixes for porting compilation on WIN32:
755 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
756 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
757 since declared 'obsolete' in WIN32 platforms.
758
75927th November 2002 John Allison (vis-V04-01-08)
760- Improved algorithm of CompareForKernelVisit.
761
76211th November 2002 John Allison (opengl-V04-01-02)
763- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
764- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
765 call default but there as a marker and encourager.
766- Added tracking and digits+hits/hits to GNUmakefile.
767
76816th October 2002 John Allison (opengl-V04-01-01)
769- Fix for WIN32. Now compiles but viewer not implemented.
770
77124th June 2002 John Allison (opengl-V04-01-00)
772- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
773
77410th June 2002 John Allison (opengl-V04-00-03)
775- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
776
7776th June 2002 John Allison (opengl-V04-00-02)
778- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
779
78023rd February 2002 John Allison (opengl-V04-00-01)
781- Changes to encourage compilation on Windows in preparation for
782 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
783 glx.h, unistd.h and assert.h.
784
78524th August 2001 John Allison (vis-V03-02-13)
786- Limited the printing of warnings in
787 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
788
78914th August 2001 John Allison (vis-V03-02-11)
790- Improved KernelVisitDecision.
791- Fixed a few small bugs in multiple "stored" viewers, but see next item.
792- There's an outstanding bug in OpenGL Stored. If there is more than
793 one viewer controlled by a scene handler, after a ClearStore on the
794 scene handler, e.g., with /vis/scene/notifyHandlers, the first
795 viewer to get refreshed should trigger the display list rebuild, but
796 the second need not. However, when the second viewer's turn comes,
797 the display lists are there, and are called, e.g.,
798 G4OpenGLStoredXViewer::DrawView calls
799 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
800 nothing appears on the screen. To overcome this there is some
801 temporary code in G4VViewer::NeedKernelVisit which marks *all*
802 viewers to force a rebuild. To see the symptoms, comment out that
803 temporary code and issue these commands:
804 /vis/verbose c
805 /control/verbose 2
806 /vis/scene/create
807 /vis/scene/add/volume
808 /vis/sceneHandler/create OGLSX
809 /vis/viewer/create ! ! 1
810 /run/beamOn
811 /vis/viewer/create ! ! 1
812 /vis/viewer/select viewer-0
813 /vis/viewer/viewpointThetaPhi 20 20
814 /vis/viewer/select viewer-1
815 /vis/viewer/viewpointThetaPhi 40 40
816 /vis/viewer/set/style surface
817 /vis/viewer/refresh
818 /vis/viewer/select viewer-0
819 /vis/viewer/refresh
820 /vis/viewer/select viewer-1
821 /vis/viewer/set/style wireframe
822 /vis/scene/notifyHandlers
823 You may have to do this too:
824 /vis/viewer/select viewer-0
825 /vis/scene/notifyHandlers
826 One of the viewers is empty. Curious!!
827
8289th August 2001 John Allison (vis-V03-02-10-00)
829- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
830- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
831 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
832 picked up by inheritance anyway.
833- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
834- Corrected order of calling base class functions in
835 G4OpenGLStoredSceneHandler::Begin/EndModeling.
836
83724th July 2001 John Allison (vis-V03-02-06)
838- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
839
84014th July 2001 John Allison (opengl-V03-02-00)
841- Fixed crash in optimised mode: added Initialise() to viewers so
842 that windows are opened after viewers are fully constructed.
843
8442nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
845- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
846
8477th March 2001 John Allison
848- Changed char* to const char* in many places and that gave problems in
849 calls to Xt and Xm. Hope all's OK. Differences:
850 cvs diff -r vis-V03-00-06 vis-V03-00-07
851
85225th January 2001 John Allison (opengl-V03-00-00)
853- Implemented running re-calculation of up-vector in the case of "object
854 rotation" (lights move with camera) to prevent "flipping" of view when
855 camera passes through up-vector. Note that the default is "camera
856 rotation" (lights do not move with camera, i.e., remain fixed relative
857 to object) so the default is that this "flipping" can happen. To set
858 "object rotation" (lights move with camera) use
859 /vis/lights/move_with_camera true (soon to be
860 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
861 on Rotation Panel in OpenGLXm mode.
862- Changed some objects to references for efficiency. E.g.:
863 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
864
86522nd May 2000 John Allison (opengl-V01-01-00)
866- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
867 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
868 static XVisualInfo* vi_single_buffer;
869 static XVisualInfo* vi_double_buffer;
870- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
871 G4OpenGLXViewer.
872- Protected double deletion of window in destructors of G4OpenGLXmViewer
873 and G4OpenGLXViewer (Guy Barrand).
874- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
875- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
876 constructors.
Note: See TracBrowser for help on using the repository browser.
