221 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
222 and "/vis/ogl/printEPS").
223
2248th May 2007 John Allison (opengl-V08-02-06)
225- Moved vectored PostScript printing to G4OpenGLViewer.
226- /vis/ogl/printEPS should work for all viewers, including Win32.
227- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
228 effective on X windows (and still somewhat buggy).
229
2304th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
231- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
232 for OGL*Win32. Still doesn't work for OGL*Xm.
233
2343rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
235- G4OpenGLStoredSceneHandler:
236 o Re-organised display lists on a per-primitive basis, i.e., one
237 display list per primitive. (This is so that, except for text,
238 the colour - or, rather, intensity - can be brought out of the
239 display list into the TOList (Transient Object List) and
240 controlled for the Display-by-Time feature. Previously, if more
241 than one primitive were drawn between BeginPrimitives and
242 EndPrimitives, it would finish up all in one display list, colour
243 commands included. Rationalises and fixes a rare bug in the
244 Display-by-Time feature - see August 2006.)
245 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
246 one primoitive to fit with the above re-organisation.
247- Implemented picking for OGLIX.
248
24925th March 2007 John Allison (opengl-V08-02-03)
250- Fix compiler warnings.
251
2528th February 2007 John Allison (opengl-V08-02-02)
253- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
254- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
255 .but not switched back. Not serious, because context was always set
256 before normal drawing.)
257
2589th January 2007 John Allison (opengl-V08-02-01)
259- Implemented bitmap markers for MarkerSizeType == screen. (The old
260 polygon implementation remains for MarkerSizeType == world.)
261- Added G4OpenGLBitMapStore to assist the above.
262- G4OpenGLXViewer::CreateGLXContext:
263 o Bug fix: Added missing break in colormap lookup routine.
264
2655th January 2007 John Allison (opengl-V08-02-00)
266- G4OpenGLSceneHandler.cc:
267 o Followed change of signature of GetLineWidth in visman-V08-02-00.
268 o Minor efficiency improvements.
269
27021st November 2006 John Allison (opengl-V08-01-09)
271- Fixed compiler warnings.
272
2731st November 2006 John Allison (opengl-V08-01-08)
274- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
275 actually initiates a print, rather than set a flag for printing.
276
27724th October 2006 John Allison (opengl-V08-01-07)
278- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
279- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
280
28119th September 2006 John Allison (opengl-V08-01-06)
282- Added time origin for light front.
283- Added /vis/ogl/set/transparency.
284- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
285
2864th September 2006 John Allison (opengl-V08-01-05)
287- Implement cutaways.
288- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
289 primitives (see detector being drawn).
290- /vis/oglx/set/printEPS: change parameter default to true.
291
29230th August 2006 John Allison (opengl-V08-01-04)
293- G4OpenGLSceneHandler:
294 o Implemented line width.
295 o Switched off back face culling when clipping so that the inside of
296 volumes can be seen.
297 o Added CreateSection/CutawayPolyhedron to exploit generic
298 sectioning (DCUT) and cutaways. Currently not activated due to
299 instabilities in BooleanProcessor. Local sectioning still active
300 but broken (at least on Mac) due to apparent change in effect of
301 clipping planes (polyhedron edges not reconstructed).
302 o Rationalised calculation of marker size.
303- G4OpenGLStoredSceneHandler:
304 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
305 o Pick up time range from G4VisAttributes.
306- G4OpenGLViewer(Messenger):
307 o Added position and colour to /vis/ogl/set/displayHeadTime.
308 o Added /vis/ogl/set/displayLightFront.
309- G4OpenGLStoredViewer.cc:
310 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
311 o Added position and colour to DisplayHeadTime.
312 o Added DisplayLightFront.
313
31416th August 2006 John Allison (opengl-V08-01-03)
315- Corrected Solaris compilation error.
316- Added /vis/ogl/set/fade and displayHeadTime.
317
31814th August 2006 John Allison (opengl-V08-01-02)
319- Needs visman-V08-01-02.
320- G4OpenGLStored: Implemented display-by-time. Only available in
321 stored mode at present. Only implemented for circle, square,
322 polyline and polymarker at present, enough for currently available
323 trajectory models. Time is communicated via G4AttValues.
324- Added G4OpenGLViewerMessenger.
325- Added /vis/ogl/set/startTime and endTime of displayed objects.
326- All factories: Instantiated G4OpenGLViewerMessenger.
327- G4OpenGLViewer: Added fStart/EndTime.
328- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
329 spewPrimitiveEPS and spewSortedFeedback.
330
33117th July John Allison (opengl-V08-01-01)
332- Added /vis/oglx/set/printEPS (prints eps file on every update).
333
3343rd July 2006 John Allison (opengl-V08-01-00)
335- Elimination of redundant variable doublebuffer and implementation of
336 FinishView in all viewers.
337
33830th May 2006 Joseph Perl (opengl-V08-00-08)
339- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
340 variable seems to have random behavior and should be assumed false for
341 this viewer.
342
34329th May 2006 Joseph Perl (opengl-V08-00-07)
344- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
345 Removed common FinishView and instead made separate FinishView for the two different
346 versions of this viewer since each wants a different buffer swapping behaviour.
347
34812th May 2006 John Allison (opengl-V08-00-06)
349- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
350
35128th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
352- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
353 recomputing transients.
354
35524th April 2006 John Allison (opengl-V08-00-04)
356- Fixed compilation problem on Windows.
357
35819th April 2006 John Allison (opengl-V08-00-03)
359- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
360 G4OpenGLImmediateSceneHandler:
361 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
362 greps-V08-00-02).
363 o Migrated to direct access to G4PhysicalVolumeModel.
364- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
365 of display lists in DrawView.
366
36714th March 2006 John Allison (opengl-V08-00-02)
368- Refined display list building and re-drawing algorithm.
369 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
370 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
371- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
372 re-use algorithm. In test19 with global culling off, numbers of
373 display lists used are:
374 o 191 No re-use:
375 o 73 Before this change: re-use except replicas (includes parameterised).
376 o 33 After this change: re-use except parameterised and replicas in radius.
377
37826th January 2006 John Allison (opengl-V08-00-01)
379- Coworks with visman-V08-00-04 (removed fModified).
380- Removed references to fModified.
381- Tidying: Removed unnecessary ClearView.
382- G4OpenGLSceneHandler.cc: Added some (commented out) code for
383 possible future implementation of 2D drawing.
384- G4OpenGLXViewer.cc: Improved exception printing.
385
38611th January 2006 John Allison (opengl-V08-00-00)
387- Improved efficiency: all DrawView's:
388 o Don't call ClearView.
389 o Set flag so SetView will not be called in ProcessView.
390 o Leave background colour to ClearView.
391- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
392- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
393 for current viewer.
394
39524th November 2005 John Allison (opengl-V07-01-09)
396- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
397

415- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
416 scene handler.
417- Re-implemented transparency button in OpenGLXm.
418
41913th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
420- Implemented white background for all OGL viewers.
421- G4OpenGLSceneHandler.cc:
422 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
423 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
424 o Corrected GetTextColour(text).
425 o Corrected GetColour(polyhedron).
426
4275th September 2005 John Allison (opengl-V07-01-03)
428- Bug fix: stored transparent objects were being lost.
429
4302nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
431- Bug fix: edgeflags problem introduced with smooth shading in
432 opengl-V07-01-00.
433- Implementation of a "better algorithm" for the rendering of
434 transparent polyhedron objects. It renders all opaque objects
435 first, then renders the transparent objects with the depth buffer in
436 read-only mode (see OpenGL Programming Guide). It uses the new
437 facility in G4VSceneHandler::ProcessScene for an optional second pass
438 of the run-duration models in the scene. Note this algorithm is
439 still only an approximation. It will still give the wrong blended
440 colour if two transparent objects are rendered front first. For
441 nested transparent objects, this is unfortunate, because
442 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
443 in such a way that mothers come first. Also, there is no guaranteed
444 relationship between the order of rendering and the depth of two
445 transparent objects if they are at the same level or in different
446 branches of the hierarchy. Still, the only error will be an
447 incorrect colour - the objects will still give the appearance of
448 transparency, so it's a pretty good algorithm. (An even better
449 algorithm would be to attempt to render the facets in depth order,
450 deepest first. But how do you calculate the depth - centre of area,
451 deepest corner? One can still imagine pathalogical cases that would
452 sometimes give the wrong colour. Also, for stored mode, the order
453 is fixed in a display list so when the user rotates the view, one
454 would lose the depth ordering. I think we have to accept that
455 blending in OpenGL is only ever an approximation. For accurate
456 blending, use RayTracer.)
457
45828th August 2005 John Allison (opengl-V07-01-01)
459- Half-way implementation of rendering of transparent polyhedron
460 objects. In this implementation, no account is taken of the order
461 of rendering. Transparent objects are rendered with depth testing
462 off so that objects behind can still be seen. But this means that
463 opaque objects in front do not obscure them - and they jolly well
464 should! A better algorithm is to render all opaque objects first,
465 then render the transparent objects with the depth buffer in
466 read-only mode (see OpenGL Programming Guide). This is going to
467 take a little more thought - see opengl-V07-01-02.
468
46920th July 2005 John Allison (opengl-V07-01-00)
470- Introduced smooth shading, taking advantage of hitherto un-noticed
471 feature of HepPolyhedron::GetNextFacet that calculates the normals
472 at each vertex so that curved surfaces are rendered more
473 realistically (Gouraud shading).
474- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
475- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
476 the default window size. It used to be 400x400, hardcoded in
477 G4OpenGLXmViewer.cc, but now it picks up the
478 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
479 The user may change it on the command line, e.g:
480 /vis/open OGLSXm 500
481 or
482 /vis/viewer/create ! ! 500
483
48430th May 2005 John Allison (opengl-V07-00-03)
485- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
486 map of vectors in G4OpenGLFontBaseStore.)
487
4884th May 2005 John Allison (opengl-V07-00-02)
489- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
490 was taken out to prevent recursive calling, but that seems to be OK,
491 and it is needed to implement refresh at end of event/run.)
492
49322nd April 2005 John Allison (opengl-V07-00-01)
494- Rationalised work of opengl-V07-00-00. Functionality unchanged.
495 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
496 o In all concrete viewers, added call to CreateFontLists().
497 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
498 o There is no longer a need to implement in the XmViewer, since it
499 now inherits. Thus the font code now only appears once for X.
500 o Awaiting implementation for WIN32.
501
50217th April 2005 John Allison (opengl-V07-00-00)
503- Based on vis-V07-00-13.
504- Implemented text for X-Windows viewers. Uses glXUseXFont, which
505 creates display lists for nominated fonts. Simple-minded scheme in
506 which each viewer creates its own font display lists for a variety
507 of sizes, which are accessed by the scene handler through a new
508 class, G4OpenGLFontBaseStore. Affected methods:
509 G4OpenGLXViewer::CreateMainWindow()
510 G4OpenGLXmViewer::CreateMainWindow()
511 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
512
51318th November 2004 John Allison (opengl-V06-02-07)
514- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
515
51615th November 2004 Guy Barrand
517- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
518 to see trajectories (for example with N03). Correct so that
519 ShowView do a FinishView that does : glFlush, wglSwapBuffer
520 and empty the Windows message queue.
521
52222nd September 2004 John Allison (opengl-V06-02-06)
523- doxygen output to tmp area.
524- Trap non-regular polyhedrons.
525
52613th September 2004 Gabriele Cosmo (opengl-V06-02-05)
527- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
528 to allow for porting on CLHEP-1.9.X series.
529
53023rd July 2004 John Allison
531- Draws auxiliary edges if required.
532- Added auxiliary edge button.
533
53416th July 2004 John Allison (opengl-V06-02-04)
535- Refinements to hidden line, hidden surface removal.
536
53714th July 2004 John Allison (opengl-V06-02-03)
538- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
539
54013th July 2004 John Allison (opengl-V06-02-02)
541- Hidden line *and* hidden surface removal now works.
542
5439th July 2004 John Allison (opengl-V06-02-01)
544- Fixed long-standing problem with hidden line removal.
545- Improved messages on failure to get visual.
546- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
547 systems provided by default anyway, so no effect.
548
5491st July 2004 John Allison (opengl-V06-02-00)
550- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
551- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
552
55318th June 2004 Gunter Folger (geant4-06-02)
5549th June 2004 Gabriele Cosmo (vis-V06-01-03)
5557th June 2004 Gabriele Cosmo (vis-V06-01-02)
556- GNUmakefile and disclaimer changes - see visualization/History.
557
5589th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
559- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
560
5617th April 2004 Guy Barrand
562- visualization/OpenGL/* : use the G4OpenGL.hh file.
563- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
564 the include of gl/gl.h and gl/glu.h that may be platform dependant.
565 It permits to rm some #ifdef WIN32 spread in the code. It opens also
566 the way to the usage of the Apple OpenGL on a Mac.
567
56817th February 2004 John Allison (opengl-V06-00-00)
569- Fixed bug #581: wrong order of statements in
570 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
571
5724th October 2003 Gabriele Cosmo (vis-V05-02-01)
573- GNUmakefile:
574 o replaced "digits+hits" with "digits_hits".
575- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
576
57722nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
578- Cosmetic change to regularise names:
579 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
580 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
581
58223rd June 2003 Guy Barrand (opengl-V05-01-02)
583- Commit a first implementation of G4OpenGLWin32Viewer.
584
58510th June 2003 Gabriele Cosmo (opengl-V05-01-01)
586- More fixes for warnings in viewers classes.
587- Added inclusion of <windows.h> for WIN32 platforms when GL headers
588 are included.
589
59005th June 2003 Gabriele Cosmo (opengl-V05-01-00)
591- Fixes for porting compilation on WIN32:
592 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
593 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
594 since declared 'obsolete' in WIN32 platforms.
595
59627th November 2002 John Allison (vis-V04-01-08)
597- Improved algorithm of CompareForKernelVisit.
598
59911th November 2002 John Allison (opengl-V04-01-02)
600- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
601- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
602 call default but there as a marker and encourager.
603- Added tracking and digits+hits/hits to GNUmakefile.
604
60516th October 2002 John Allison (opengl-V04-01-01)
606- Fix for WIN32. Now compiles but viewer not implemented.
607
60824th June 2002 John Allison (opengl-V04-01-00)
609- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
610
61110th June 2002 John Allison (opengl-V04-00-03)
612- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
613
6146th June 2002 John Allison (opengl-V04-00-02)
615- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
616
61723rd February 2002 John Allison (opengl-V04-00-01)
618- Changes to encourage compilation on Windows in preparation for
619 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
620 glx.h, unistd.h and assert.h.
621
62224th August 2001 John Allison (vis-V03-02-13)
623- Limited the printing of warnings in
624 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
625
62614th August 2001 John Allison (vis-V03-02-11)
627- Improved KernelVisitDecision.
628- Fixed a few small bugs in multiple "stored" viewers, but see next item.
629- There's an outstanding bug in OpenGL Stored. If there is more than
630 one viewer controlled by a scene handler, after a ClearStore on the
631 scene handler, e.g., with /vis/scene/notifyHandlers, the first
632 viewer to get refreshed should trigger the display list rebuild, but
633 the second need not. However, when the second viewer's turn comes,
634 the display lists are there, and are called, e.g.,
635 G4OpenGLStoredXViewer::DrawView calls
636 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
637 nothing appears on the screen. To overcome this there is some
638 temporary code in G4VViewer::NeedKernelVisit which marks *all*
639 viewers to force a rebuild. To see the symptoms, comment out that
640 temporary code and issue these commands:
641 /vis/verbose c
642 /control/verbose 2
643 /vis/scene/create
644 /vis/scene/add/volume
645 /vis/sceneHandler/create OGLSX
646 /vis/viewer/create ! ! 1
647 /run/beamOn
648 /vis/viewer/create ! ! 1
649 /vis/viewer/select viewer-0
650 /vis/viewer/viewpointThetaPhi 20 20
651 /vis/viewer/select viewer-1
652 /vis/viewer/viewpointThetaPhi 40 40
653 /vis/viewer/set/style surface
654 /vis/viewer/refresh
655 /vis/viewer/select viewer-0
656 /vis/viewer/refresh
657 /vis/viewer/select viewer-1
658 /vis/viewer/set/style wireframe
659 /vis/scene/notifyHandlers
660 You may have to do this too:
661 /vis/viewer/select viewer-0
662 /vis/scene/notifyHandlers
663 One of the viewers is empty. Curious!!
664
6659th August 2001 John Allison (vis-V03-02-10-00)
666- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
667- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
668 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
669 picked up by inheritance anyway.
670- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
671- Corrected order of calling base class functions in
672 G4OpenGLStoredSceneHandler::Begin/EndModeling.
673
67424th July 2001 John Allison (vis-V03-02-06)
675- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
676
67714th July 2001 John Allison (opengl-V03-02-00)
678- Fixed crash in optimised mode: added Initialise() to viewers so
679 that windows are opened after viewers are fully constructed.
680
6812nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
682- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
683
6847th March 2001 John Allison
685- Changed char* to const char* in many places and that gave problems in
686 calls to Xt and Xm. Hope all's OK. Differences:
687 cvs diff -r vis-V03-00-06 vis-V03-00-07
688
68925th January 2001 John Allison (opengl-V03-00-00)
690- Implemented running re-calculation of up-vector in the case of "object
691 rotation" (lights move with camera) to prevent "flipping" of view when
692 camera passes through up-vector. Note that the default is "camera
693 rotation" (lights do not move with camera, i.e., remain fixed relative
694 to object) so the default is that this "flipping" can happen. To set
695 "object rotation" (lights move with camera) use
696 /vis/lights/move_with_camera true (soon to be
697 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
698 on Rotation Panel in OpenGLXm mode.
699- Changed some objects to references for efficiency. E.g.:
700 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
701
70222nd May 2000 John Allison (opengl-V01-01-00)
703- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
704 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
705 static XVisualInfo* vi_single_buffer;
706 static XVisualInfo* vi_double_buffer;
707- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
708 G4OpenGLXViewer.
709- Protected double deletion of window in destructors of G4OpenGLXmViewer
710 and G4OpenGLXViewer (Guy Barrand).
711- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
712- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
713 constructors.
