215 and "/vis/ogl/printEPS").
216
2178th May 2007 John Allison (opengl-V08-02-06)
218- Moved vectored PostScript printing to G4OpenGLViewer.
219- /vis/ogl/printEPS should work for all viewers, including Win32.
220- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
221 effective on X windows (and still somewhat buggy).
222
2234th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
224- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
225 for OGL*Win32. Still doesn't work for OGL*Xm.
226
2273rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
228- G4OpenGLStoredSceneHandler:
229 o Re-organised display lists on a per-primitive basis, i.e., one
230 display list per primitive. (This is so that, except for text,
231 the colour - or, rather, intensity - can be brought out of the
232 display list into the TOList (Transient Object List) and
233 controlled for the Display-by-Time feature. Previously, if more
234 than one primitive were drawn between BeginPrimitives and
235 EndPrimitives, it would finish up all in one display list, colour
236 commands included. Rationalises and fixes a rare bug in the
237 Display-by-Time feature - see August 2006.)
238 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
239 one primoitive to fit with the above re-organisation.
240- Implemented picking for OGLIX.
241
24225th March 2007 John Allison (opengl-V08-02-03)
243- Fix compiler warnings.
244
2458th February 2007 John Allison (opengl-V08-02-02)
246- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
247- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
248 .but not switched back. Not serious, because context was always set
249 before normal drawing.)
250
2519th January 2007 John Allison (opengl-V08-02-01)
252- Implemented bitmap markers for MarkerSizeType == screen. (The old
253 polygon implementation remains for MarkerSizeType == world.)
254- Added G4OpenGLBitMapStore to assist the above.
255- G4OpenGLXViewer::CreateGLXContext:
256 o Bug fix: Added missing break in colormap lookup routine.
257
2585th January 2007 John Allison (opengl-V08-02-00)
259- G4OpenGLSceneHandler.cc:
260 o Followed change of signature of GetLineWidth in visman-V08-02-00.
261 o Minor efficiency improvements.
262
26321st November 2006 John Allison (opengl-V08-01-09)
264- Fixed compiler warnings.
265
2661st November 2006 John Allison (opengl-V08-01-08)
267- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
268 actually initiates a print, rather than set a flag for printing.
269
27024th October 2006 John Allison (opengl-V08-01-07)
271- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.

277- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
278
2794th September 2006 John Allison (opengl-V08-01-05)
280- Implement cutaways.
281- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
282 primitives (see detector being drawn).
283- /vis/oglx/set/printEPS: change parameter default to true.
284
28530th August 2006 John Allison (opengl-V08-01-04)
286- G4OpenGLSceneHandler:
287 o Implemented line width.
288 o Switched off back face culling when clipping so that the inside of
289 volumes can be seen.
290 o Added CreateSection/CutawayPolyhedron to exploit generic
291 sectioning (DCUT) and cutaways. Currently not activated due to
292 instabilities in BooleanProcessor. Local sectioning still active
293 but broken (at least on Mac) due to apparent change in effect of
294 clipping planes (polyhedron edges not reconstructed).
295 o Rationalised calculation of marker size.
296- G4OpenGLStoredSceneHandler:
297 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
298 o Pick up time range from G4VisAttributes.
299- G4OpenGLViewer(Messenger):
300 o Added position and colour to /vis/ogl/set/displayHeadTime.
301 o Added /vis/ogl/set/displayLightFront.
302- G4OpenGLStoredViewer.cc:
303 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
304 o Added position and colour to DisplayHeadTime.
305 o Added DisplayLightFront.
306
30716th August 2006 John Allison (opengl-V08-01-03)
308- Corrected Solaris compilation error.
309- Added /vis/ogl/set/fade and displayHeadTime.
310
31114th August 2006 John Allison (opengl-V08-01-02)
312- Needs visman-V08-01-02.
313- G4OpenGLStored: Implemented display-by-time. Only available in
314 stored mode at present. Only implemented for circle, square,
315 polyline and polymarker at present, enough for currently available
316 trajectory models. Time is communicated via G4AttValues.
317- Added G4OpenGLViewerMessenger.
318- Added /vis/ogl/set/startTime and endTime of displayed objects.
319- All factories: Instantiated G4OpenGLViewerMessenger.
320- G4OpenGLViewer: Added fStart/EndTime.
321- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
322 spewPrimitiveEPS and spewSortedFeedback.
323
32417th July John Allison (opengl-V08-01-01)
325- Added /vis/oglx/set/printEPS (prints eps file on every update).
326
3273rd July 2006 John Allison (opengl-V08-01-00)
328- Elimination of redundant variable doublebuffer and implementation of
329 FinishView in all viewers.
330
33130th May 2006 Joseph Perl (opengl-V08-00-08)
332- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
333 variable seems to have random behavior and should be assumed false for
334 this viewer.
335
33629th May 2006 Joseph Perl (opengl-V08-00-07)
337- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
338 Removed common FinishView and instead made separate FinishView for the two different
339 versions of this viewer since each wants a different buffer swapping behaviour.
340
34112th May 2006 John Allison (opengl-V08-00-06)
342- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
343
34428th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
345- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
346 recomputing transients.
347
34824th April 2006 John Allison (opengl-V08-00-04)
349- Fixed compilation problem on Windows.
350
35119th April 2006 John Allison (opengl-V08-00-03)
352- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
353 G4OpenGLImmediateSceneHandler:
354 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
355 greps-V08-00-02).
356 o Migrated to direct access to G4PhysicalVolumeModel.
357- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
358 of display lists in DrawView.
359
36014th March 2006 John Allison (opengl-V08-00-02)
361- Refined display list building and re-drawing algorithm.
362 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
363 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
364- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
365 re-use algorithm. In test19 with global culling off, numbers of
366 display lists used are:
367 o 191 No re-use:
368 o 73 Before this change: re-use except replicas (includes parameterised).
369 o 33 After this change: re-use except parameterised and replicas in radius.
370
37126th January 2006 John Allison (opengl-V08-00-01)
372- Coworks with visman-V08-00-04 (removed fModified).
373- Removed references to fModified.
374- Tidying: Removed unnecessary ClearView.
375- G4OpenGLSceneHandler.cc: Added some (commented out) code for
376 possible future implementation of 2D drawing.
377- G4OpenGLXViewer.cc: Improved exception printing.
378
37911th January 2006 John Allison (opengl-V08-00-00)
380- Improved efficiency: all DrawView's:
381 o Don't call ClearView.
382 o Set flag so SetView will not be called in ProcessView.
383 o Leave background colour to ClearView.
384- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
385- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
386 for current viewer.
387
38824th November 2005 John Allison (opengl-V07-01-09)
389- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
390

408- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
409 scene handler.
410- Re-implemented transparency button in OpenGLXm.
411
41213th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
413- Implemented white background for all OGL viewers.
414- G4OpenGLSceneHandler.cc:
415 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
416 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
417 o Corrected GetTextColour(text).
418 o Corrected GetColour(polyhedron).
419
4205th September 2005 John Allison (opengl-V07-01-03)
421- Bug fix: stored transparent objects were being lost.
422
4232nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
424- Bug fix: edgeflags problem introduced with smooth shading in
425 opengl-V07-01-00.
426- Implementation of a "better algorithm" for the rendering of
427 transparent polyhedron objects. It renders all opaque objects
428 first, then renders the transparent objects with the depth buffer in
429 read-only mode (see OpenGL Programming Guide). It uses the new
430 facility in G4VSceneHandler::ProcessScene for an optional second pass
431 of the run-duration models in the scene. Note this algorithm is
432 still only an approximation. It will still give the wrong blended
433 colour if two transparent objects are rendered front first. For
434 nested transparent objects, this is unfortunate, because
435 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
436 in such a way that mothers come first. Also, there is no guaranteed
437 relationship between the order of rendering and the depth of two
438 transparent objects if they are at the same level or in different
439 branches of the hierarchy. Still, the only error will be an
440 incorrect colour - the objects will still give the appearance of
441 transparency, so it's a pretty good algorithm. (An even better
442 algorithm would be to attempt to render the facets in depth order,
443 deepest first. But how do you calculate the depth - centre of area,
444 deepest corner? One can still imagine pathalogical cases that would
445 sometimes give the wrong colour. Also, for stored mode, the order
446 is fixed in a display list so when the user rotates the view, one
447 would lose the depth ordering. I think we have to accept that
448 blending in OpenGL is only ever an approximation. For accurate
449 blending, use RayTracer.)
450
45128th August 2005 John Allison (opengl-V07-01-01)
452- Half-way implementation of rendering of transparent polyhedron
453 objects. In this implementation, no account is taken of the order
454 of rendering. Transparent objects are rendered with depth testing
455 off so that objects behind can still be seen. But this means that
456 opaque objects in front do not obscure them - and they jolly well
457 should! A better algorithm is to render all opaque objects first,
458 then render the transparent objects with the depth buffer in
459 read-only mode (see OpenGL Programming Guide). This is going to
460 take a little more thought - see opengl-V07-01-02.
461
46220th July 2005 John Allison (opengl-V07-01-00)
463- Introduced smooth shading, taking advantage of hitherto un-noticed
464 feature of HepPolyhedron::GetNextFacet that calculates the normals
465 at each vertex so that curved surfaces are rendered more
466 realistically (Gouraud shading).
467- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
468- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
469 the default window size. It used to be 400x400, hardcoded in
470 G4OpenGLXmViewer.cc, but now it picks up the
471 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
472 The user may change it on the command line, e.g:
473 /vis/open OGLSXm 500
474 or
475 /vis/viewer/create ! ! 500
476
47730th May 2005 John Allison (opengl-V07-00-03)
478- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
479 map of vectors in G4OpenGLFontBaseStore.)
480
4814th May 2005 John Allison (opengl-V07-00-02)
482- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
483 was taken out to prevent recursive calling, but that seems to be OK,
484 and it is needed to implement refresh at end of event/run.)
485
48622nd April 2005 John Allison (opengl-V07-00-01)
487- Rationalised work of opengl-V07-00-00. Functionality unchanged.
488 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
489 o In all concrete viewers, added call to CreateFontLists().
490 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
491 o There is no longer a need to implement in the XmViewer, since it
492 now inherits. Thus the font code now only appears once for X.
493 o Awaiting implementation for WIN32.
494
49517th April 2005 John Allison (opengl-V07-00-00)
496- Based on vis-V07-00-13.
497- Implemented text for X-Windows viewers. Uses glXUseXFont, which
498 creates display lists for nominated fonts. Simple-minded scheme in
499 which each viewer creates its own font display lists for a variety
500 of sizes, which are accessed by the scene handler through a new
501 class, G4OpenGLFontBaseStore. Affected methods:
502 G4OpenGLXViewer::CreateMainWindow()
503 G4OpenGLXmViewer::CreateMainWindow()
504 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
505
50618th November 2004 John Allison (opengl-V06-02-07)
507- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
508
50915th November 2004 Guy Barrand
510- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
511 to see trajectories (for example with N03). Correct so that
512 ShowView do a FinishView that does : glFlush, wglSwapBuffer
513 and empty the Windows message queue.
514
51522nd September 2004 John Allison (opengl-V06-02-06)
516- doxygen output to tmp area.
517- Trap non-regular polyhedrons.
518
51913th September 2004 Gabriele Cosmo (opengl-V06-02-05)
520- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
521 to allow for porting on CLHEP-1.9.X series.
522
52323rd July 2004 John Allison
524- Draws auxiliary edges if required.
525- Added auxiliary edge button.
526
52716th July 2004 John Allison (opengl-V06-02-04)
528- Refinements to hidden line, hidden surface removal.
529
53014th July 2004 John Allison (opengl-V06-02-03)
531- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
532
53313th July 2004 John Allison (opengl-V06-02-02)
534- Hidden line *and* hidden surface removal now works.
535
5369th July 2004 John Allison (opengl-V06-02-01)
537- Fixed long-standing problem with hidden line removal.
538- Improved messages on failure to get visual.
539- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
540 systems provided by default anyway, so no effect.
541
5421st July 2004 John Allison (opengl-V06-02-00)
543- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
544- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
545
54618th June 2004 Gunter Folger (geant4-06-02)
5479th June 2004 Gabriele Cosmo (vis-V06-01-03)
5487th June 2004 Gabriele Cosmo (vis-V06-01-02)
549- GNUmakefile and disclaimer changes - see visualization/History.
550
5519th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
552- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
553
5547th April 2004 Guy Barrand
555- visualization/OpenGL/* : use the G4OpenGL.hh file.
556- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
557 the include of gl/gl.h and gl/glu.h that may be platform dependant.
558 It permits to rm some #ifdef WIN32 spread in the code. It opens also
559 the way to the usage of the Apple OpenGL on a Mac.
560
56117th February 2004 John Allison (opengl-V06-00-00)
562- Fixed bug #581: wrong order of statements in
563 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
564
5654th October 2003 Gabriele Cosmo (vis-V05-02-01)
566- GNUmakefile:
567 o replaced "digits+hits" with "digits_hits".
568- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
569
57022nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
571- Cosmetic change to regularise names:
572 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
573 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
574
57523rd June 2003 Guy Barrand (opengl-V05-01-02)
576- Commit a first implementation of G4OpenGLWin32Viewer.
577
57810th June 2003 Gabriele Cosmo (opengl-V05-01-01)
579- More fixes for warnings in viewers classes.
580- Added inclusion of <windows.h> for WIN32 platforms when GL headers
581 are included.
582
58305th June 2003 Gabriele Cosmo (opengl-V05-01-00)
584- Fixes for porting compilation on WIN32:
585 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
586 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
587 since declared 'obsolete' in WIN32 platforms.
588
58927th November 2002 John Allison (vis-V04-01-08)
590- Improved algorithm of CompareForKernelVisit.
591
59211th November 2002 John Allison (opengl-V04-01-02)
593- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
594- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
595 call default but there as a marker and encourager.
596- Added tracking and digits+hits/hits to GNUmakefile.
597
59816th October 2002 John Allison (opengl-V04-01-01)
599- Fix for WIN32. Now compiles but viewer not implemented.
600
60124th June 2002 John Allison (opengl-V04-01-00)
602- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
603
60410th June 2002 John Allison (opengl-V04-00-03)
605- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
606
6076th June 2002 John Allison (opengl-V04-00-02)
608- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
609
61023rd February 2002 John Allison (opengl-V04-00-01)
611- Changes to encourage compilation on Windows in preparation for
612 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
613 glx.h, unistd.h and assert.h.
614
61524th August 2001 John Allison (vis-V03-02-13)
616- Limited the printing of warnings in
617 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
618
61914th August 2001 John Allison (vis-V03-02-11)
620- Improved KernelVisitDecision.
621- Fixed a few small bugs in multiple "stored" viewers, but see next item.
622- There's an outstanding bug in OpenGL Stored. If there is more than
623 one viewer controlled by a scene handler, after a ClearStore on the
624 scene handler, e.g., with /vis/scene/notifyHandlers, the first
625 viewer to get refreshed should trigger the display list rebuild, but
626 the second need not. However, when the second viewer's turn comes,
627 the display lists are there, and are called, e.g.,
628 G4OpenGLStoredXViewer::DrawView calls
629 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
630 nothing appears on the screen. To overcome this there is some
631 temporary code in G4VViewer::NeedKernelVisit which marks *all*
632 viewers to force a rebuild. To see the symptoms, comment out that
633 temporary code and issue these commands:
634 /vis/verbose c
635 /control/verbose 2
636 /vis/scene/create
637 /vis/scene/add/volume
638 /vis/sceneHandler/create OGLSX
639 /vis/viewer/create ! ! 1
640 /run/beamOn
641 /vis/viewer/create ! ! 1
642 /vis/viewer/select viewer-0
643 /vis/viewer/viewpointThetaPhi 20 20
644 /vis/viewer/select viewer-1
645 /vis/viewer/viewpointThetaPhi 40 40
646 /vis/viewer/set/style surface
647 /vis/viewer/refresh
648 /vis/viewer/select viewer-0
649 /vis/viewer/refresh
650 /vis/viewer/select viewer-1
651 /vis/viewer/set/style wireframe
652 /vis/scene/notifyHandlers
653 You may have to do this too:
654 /vis/viewer/select viewer-0
655 /vis/scene/notifyHandlers
656 One of the viewers is empty. Curious!!
657
6589th August 2001 John Allison (vis-V03-02-10-00)
659- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
660- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
661 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
662 picked up by inheritance anyway.
663- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
664- Corrected order of calling base class functions in
665 G4OpenGLStoredSceneHandler::Begin/EndModeling.
666
66724th July 2001 John Allison (vis-V03-02-06)
668- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
669
67014th July 2001 John Allison (opengl-V03-02-00)
671- Fixed crash in optimised mode: added Initialise() to viewers so
672 that windows are opened after viewers are fully constructed.
673
6742nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
675- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
676
6777th March 2001 John Allison
678- Changed char* to const char* in many places and that gave problems in
679 calls to Xt and Xm. Hope all's OK. Differences:
680 cvs diff -r vis-V03-00-06 vis-V03-00-07
681
68225th January 2001 John Allison (opengl-V03-00-00)
683- Implemented running re-calculation of up-vector in the case of "object
684 rotation" (lights move with camera) to prevent "flipping" of view when
685 camera passes through up-vector. Note that the default is "camera
686 rotation" (lights do not move with camera, i.e., remain fixed relative
687 to object) so the default is that this "flipping" can happen. To set
688 "object rotation" (lights move with camera) use
689 /vis/lights/move_with_camera true (soon to be
690 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
691 on Rotation Panel in OpenGLXm mode.
692- Changed some objects to references for efficiency. E.g.:
693 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
694
69522nd May 2000 John Allison (opengl-V01-01-00)
696- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
697 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
698 static XVisualInfo* vi_single_buffer;
699 static XVisualInfo* vi_double_buffer;
700- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
701 G4OpenGLXViewer.
702- Protected double deletion of window in destructors of G4OpenGLXmViewer
703 and G4OpenGLXViewer (Guy Barrand).
704- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
705- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
706 constructors.
Note: See TracBrowser for help on using the repository browser.
