236 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
237 and "/vis/ogl/printEPS").
238
2398th May 2007 John Allison (opengl-V08-02-06)
240- Moved vectored PostScript printing to G4OpenGLViewer.
241- /vis/ogl/printEPS should work for all viewers, including Win32.
242- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
243 effective on X windows (and still somewhat buggy).
244
2454th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
246- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
247 for OGL*Win32. Still doesn't work for OGL*Xm.
248
2493rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
250- G4OpenGLStoredSceneHandler:
251 o Re-organised display lists on a per-primitive basis, i.e., one
252 display list per primitive. (This is so that, except for text,
253 the colour - or, rather, intensity - can be brought out of the
254 display list into the TOList (Transient Object List) and
255 controlled for the Display-by-Time feature. Previously, if more
256 than one primitive were drawn between BeginPrimitives and
257 EndPrimitives, it would finish up all in one display list, colour
258 commands included. Rationalises and fixes a rare bug in the
259 Display-by-Time feature - see August 2006.)
260 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
261 one primoitive to fit with the above re-organisation.
262- Implemented picking for OGLIX.
263
26425th March 2007 John Allison (opengl-V08-02-03)
265- Fix compiler warnings.
266
2678th February 2007 John Allison (opengl-V08-02-02)
268- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
269- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
270 .but not switched back. Not serious, because context was always set
271 before normal drawing.)
272
2739th January 2007 John Allison (opengl-V08-02-01)
274- Implemented bitmap markers for MarkerSizeType == screen. (The old
275 polygon implementation remains for MarkerSizeType == world.)
276- Added G4OpenGLBitMapStore to assist the above.
277- G4OpenGLXViewer::CreateGLXContext:
278 o Bug fix: Added missing break in colormap lookup routine.
279
2805th January 2007 John Allison (opengl-V08-02-00)
281- G4OpenGLSceneHandler.cc:
282 o Followed change of signature of GetLineWidth in visman-V08-02-00.
283 o Minor efficiency improvements.
284
28521st November 2006 John Allison (opengl-V08-01-09)
286- Fixed compiler warnings.
287
2881st November 2006 John Allison (opengl-V08-01-08)
289- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
290 actually initiates a print, rather than set a flag for printing.
291
29224th October 2006 John Allison (opengl-V08-01-07)
293- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
294- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
295
29619th September 2006 John Allison (opengl-V08-01-06)
297- Added time origin for light front.
298- Added /vis/ogl/set/transparency.
299- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
300
3014th September 2006 John Allison (opengl-V08-01-05)
302- Implement cutaways.
303- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
304 primitives (see detector being drawn).
305- /vis/oglx/set/printEPS: change parameter default to true.
306
30730th August 2006 John Allison (opengl-V08-01-04)
308- G4OpenGLSceneHandler:
309 o Implemented line width.
310 o Switched off back face culling when clipping so that the inside of
311 volumes can be seen.
312 o Added CreateSection/CutawayPolyhedron to exploit generic
313 sectioning (DCUT) and cutaways. Currently not activated due to
314 instabilities in BooleanProcessor. Local sectioning still active
315 but broken (at least on Mac) due to apparent change in effect of
316 clipping planes (polyhedron edges not reconstructed).
317 o Rationalised calculation of marker size.
318- G4OpenGLStoredSceneHandler:
319 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
320 o Pick up time range from G4VisAttributes.
321- G4OpenGLViewer(Messenger):
322 o Added position and colour to /vis/ogl/set/displayHeadTime.
323 o Added /vis/ogl/set/displayLightFront.
324- G4OpenGLStoredViewer.cc:
325 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
326 o Added position and colour to DisplayHeadTime.
327 o Added DisplayLightFront.
328
32916th August 2006 John Allison (opengl-V08-01-03)
330- Corrected Solaris compilation error.
331- Added /vis/ogl/set/fade and displayHeadTime.
332
33314th August 2006 John Allison (opengl-V08-01-02)
334- Needs visman-V08-01-02.
335- G4OpenGLStored: Implemented display-by-time. Only available in
336 stored mode at present. Only implemented for circle, square,
337 polyline and polymarker at present, enough for currently available
338 trajectory models. Time is communicated via G4AttValues.
339- Added G4OpenGLViewerMessenger.
340- Added /vis/ogl/set/startTime and endTime of displayed objects.
341- All factories: Instantiated G4OpenGLViewerMessenger.
342- G4OpenGLViewer: Added fStart/EndTime.
343- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
344 spewPrimitiveEPS and spewSortedFeedback.
345
34617th July John Allison (opengl-V08-01-01)
347- Added /vis/oglx/set/printEPS (prints eps file on every update).
348
3493rd July 2006 John Allison (opengl-V08-01-00)
350- Elimination of redundant variable doublebuffer and implementation of
351 FinishView in all viewers.
352
35330th May 2006 Joseph Perl (opengl-V08-00-08)
354- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
355 variable seems to have random behavior and should be assumed false for
356 this viewer.
357
35829th May 2006 Joseph Perl (opengl-V08-00-07)
359- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
360 Removed common FinishView and instead made separate FinishView for the two different
361 versions of this viewer since each wants a different buffer swapping behaviour.
362
36312th May 2006 John Allison (opengl-V08-00-06)
364- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
365
36628th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
367- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
368 recomputing transients.
369
37024th April 2006 John Allison (opengl-V08-00-04)
371- Fixed compilation problem on Windows.
372
37319th April 2006 John Allison (opengl-V08-00-03)
374- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
375 G4OpenGLImmediateSceneHandler:
376 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
377 greps-V08-00-02).
378 o Migrated to direct access to G4PhysicalVolumeModel.
379- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
380 of display lists in DrawView.
381
38214th March 2006 John Allison (opengl-V08-00-02)
383- Refined display list building and re-drawing algorithm.
384 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
385 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
386- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
387 re-use algorithm. In test19 with global culling off, numbers of
388 display lists used are:
389 o 191 No re-use:
390 o 73 Before this change: re-use except replicas (includes parameterised).
391 o 33 After this change: re-use except parameterised and replicas in radius.
392
39326th January 2006 John Allison (opengl-V08-00-01)
394- Coworks with visman-V08-00-04 (removed fModified).
395- Removed references to fModified.
396- Tidying: Removed unnecessary ClearView.
397- G4OpenGLSceneHandler.cc: Added some (commented out) code for
398 possible future implementation of 2D drawing.
399- G4OpenGLXViewer.cc: Improved exception printing.
400
40111th January 2006 John Allison (opengl-V08-00-00)
402- Improved efficiency: all DrawView's:
403 o Don't call ClearView.
404 o Set flag so SetView will not be called in ProcessView.
405 o Leave background colour to ClearView.
406- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
407- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
408 for current viewer.
409
41024th November 2005 John Allison (opengl-V07-01-09)
411- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
412

430- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
431 scene handler.
432- Re-implemented transparency button in OpenGLXm.
433
43413th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
435- Implemented white background for all OGL viewers.
436- G4OpenGLSceneHandler.cc:
437 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
438 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
439 o Corrected GetTextColour(text).
440 o Corrected GetColour(polyhedron).
441
4425th September 2005 John Allison (opengl-V07-01-03)
443- Bug fix: stored transparent objects were being lost.
444
4452nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
446- Bug fix: edgeflags problem introduced with smooth shading in
447 opengl-V07-01-00.
448- Implementation of a "better algorithm" for the rendering of
449 transparent polyhedron objects. It renders all opaque objects
450 first, then renders the transparent objects with the depth buffer in
451 read-only mode (see OpenGL Programming Guide). It uses the new
452 facility in G4VSceneHandler::ProcessScene for an optional second pass
453 of the run-duration models in the scene. Note this algorithm is
454 still only an approximation. It will still give the wrong blended
455 colour if two transparent objects are rendered front first. For
456 nested transparent objects, this is unfortunate, because
457 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
458 in such a way that mothers come first. Also, there is no guaranteed
459 relationship between the order of rendering and the depth of two
460 transparent objects if they are at the same level or in different
461 branches of the hierarchy. Still, the only error will be an
462 incorrect colour - the objects will still give the appearance of
463 transparency, so it's a pretty good algorithm. (An even better
464 algorithm would be to attempt to render the facets in depth order,
465 deepest first. But how do you calculate the depth - centre of area,
466 deepest corner? One can still imagine pathalogical cases that would
467 sometimes give the wrong colour. Also, for stored mode, the order
468 is fixed in a display list so when the user rotates the view, one
469 would lose the depth ordering. I think we have to accept that
470 blending in OpenGL is only ever an approximation. For accurate
471 blending, use RayTracer.)
472
47328th August 2005 John Allison (opengl-V07-01-01)
474- Half-way implementation of rendering of transparent polyhedron
475 objects. In this implementation, no account is taken of the order
476 of rendering. Transparent objects are rendered with depth testing
477 off so that objects behind can still be seen. But this means that
478 opaque objects in front do not obscure them - and they jolly well
479 should! A better algorithm is to render all opaque objects first,
480 then render the transparent objects with the depth buffer in
481 read-only mode (see OpenGL Programming Guide). This is going to
482 take a little more thought - see opengl-V07-01-02.
483
48420th July 2005 John Allison (opengl-V07-01-00)
485- Introduced smooth shading, taking advantage of hitherto un-noticed
486 feature of HepPolyhedron::GetNextFacet that calculates the normals
487 at each vertex so that curved surfaces are rendered more
488 realistically (Gouraud shading).
489- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
490- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
491 the default window size. It used to be 400x400, hardcoded in
492 G4OpenGLXmViewer.cc, but now it picks up the
493 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
494 The user may change it on the command line, e.g:
495 /vis/open OGLSXm 500
496 or
497 /vis/viewer/create ! ! 500
498
49930th May 2005 John Allison (opengl-V07-00-03)
500- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
501 map of vectors in G4OpenGLFontBaseStore.)
502
5034th May 2005 John Allison (opengl-V07-00-02)
504- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
505 was taken out to prevent recursive calling, but that seems to be OK,
506 and it is needed to implement refresh at end of event/run.)
507
50822nd April 2005 John Allison (opengl-V07-00-01)
509- Rationalised work of opengl-V07-00-00. Functionality unchanged.
510 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
511 o In all concrete viewers, added call to CreateFontLists().
512 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
513 o There is no longer a need to implement in the XmViewer, since it
514 now inherits. Thus the font code now only appears once for X.
515 o Awaiting implementation for WIN32.
516
51717th April 2005 John Allison (opengl-V07-00-00)
518- Based on vis-V07-00-13.
519- Implemented text for X-Windows viewers. Uses glXUseXFont, which
520 creates display lists for nominated fonts. Simple-minded scheme in
521 which each viewer creates its own font display lists for a variety
522 of sizes, which are accessed by the scene handler through a new
523 class, G4OpenGLFontBaseStore. Affected methods:
524 G4OpenGLXViewer::CreateMainWindow()
525 G4OpenGLXmViewer::CreateMainWindow()
526 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
527
52818th November 2004 John Allison (opengl-V06-02-07)
529- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
530
53115th November 2004 Guy Barrand
532- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
533 to see trajectories (for example with N03). Correct so that
534 ShowView do a FinishView that does : glFlush, wglSwapBuffer
535 and empty the Windows message queue.
536
53722nd September 2004 John Allison (opengl-V06-02-06)
538- doxygen output to tmp area.
539- Trap non-regular polyhedrons.
540
54113th September 2004 Gabriele Cosmo (opengl-V06-02-05)
542- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
543 to allow for porting on CLHEP-1.9.X series.
544
54523rd July 2004 John Allison
546- Draws auxiliary edges if required.
547- Added auxiliary edge button.
548
54916th July 2004 John Allison (opengl-V06-02-04)
550- Refinements to hidden line, hidden surface removal.
551
55214th July 2004 John Allison (opengl-V06-02-03)
553- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.
554
55513th July 2004 John Allison (opengl-V06-02-02)
556- Hidden line *and* hidden surface removal now works.
557
5589th July 2004 John Allison (opengl-V06-02-01)
559- Fixed long-standing problem with hidden line removal.
560- Improved messages on failure to get visual.
561- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
562 systems provided by default anyway, so no effect.
563
5641st July 2004 John Allison (opengl-V06-02-00)
565- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
566- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.
567
56818th June 2004 Gunter Folger (geant4-06-02)
5699th June 2004 Gabriele Cosmo (vis-V06-01-03)
5707th June 2004 Gabriele Cosmo (vis-V06-01-02)
571- GNUmakefile and disclaimer changes - see visualization/History.
572
5739th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
574- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
575
5767th April 2004 Guy Barrand
577- visualization/OpenGL/* : use the G4OpenGL.hh file.
578- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
579 the include of gl/gl.h and gl/glu.h that may be platform dependant.
580 It permits to rm some #ifdef WIN32 spread in the code. It opens also
581 the way to the usage of the Apple OpenGL on a Mac.
582
58317th February 2004 John Allison (opengl-V06-00-00)
584- Fixed bug #581: wrong order of statements in
585 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
586
5874th October 2003 Gabriele Cosmo (vis-V05-02-01)
588- GNUmakefile:
589 o replaced "digits+hits" with "digits_hits".
590- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
591
59222nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)
593- Cosmetic change to regularise names:
594 o changed _Feedback3Dcolo to G4OpenGLXViewerFeedback3Dcolor.
595 o changed _DepthIndex to G4OpenGLXViewerDepthIndex.
596
59723rd June 2003 Guy Barrand (opengl-V05-01-02)
598- Commit a first implementation of G4OpenGLWin32Viewer.
599
60010th June 2003 Gabriele Cosmo (opengl-V05-01-01)
601- More fixes for warnings in viewers classes.
602- Added inclusion of <windows.h> for WIN32 platforms when GL headers
603 are included.
604
60505th June 2003 Gabriele Cosmo (opengl-V05-01-00)
606- Fixes for porting compilation on WIN32:
607 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
608 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
609 since declared 'obsolete' in WIN32 platforms.
610
61127th November 2002 John Allison (vis-V04-01-08)
612- Improved algorithm of CompareForKernelVisit.
613
61411th November 2002 John Allison (opengl-V04-01-02)
615- Corrected inclusion of G4OpenGLXViewer #ifdef X_DRIVER.
616- Added G4OpenGLSceneHandler::AddThis for trajectories and hits - simply
617 call default but there as a marker and encourager.
618- Added tracking and digits+hits/hits to GNUmakefile.
619
62016th October 2002 John Allison (opengl-V04-01-01)
621- Fix for WIN32. Now compiles but viewer not implemented.
622
62324th June 2002 John Allison (opengl-V04-01-00)
624- Further cosmetic changes in G4OpenGLXViewer.cc for DEC compiler.
625
62610th June 2002 John Allison (opengl-V04-00-03)
627- Cosmetic changes for SUN-CC in G4OpenGLXmConvenienceRoutines.cc.
628
6296th June 2002 John Allison (opengl-V04-00-02)
630- Cosmetic changes for GNU compiler in G4OpenGLXViewer.cc.
631
63223rd February 2002 John Allison (opengl-V04-00-01)
633- Changes to encourage compilation on Windows in preparation for
634 implementation of G4OpenGLWin32Viewer. Removed spurious includes of
635 glx.h, unistd.h and assert.h.
636
63724th August 2001 John Allison (vis-V03-02-13)
638- Limited the printing of warnings in
639 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
640
64114th August 2001 John Allison (vis-V03-02-11)
642- Improved KernelVisitDecision.
643- Fixed a few small bugs in multiple "stored" viewers, but see next item.
644- There's an outstanding bug in OpenGL Stored. If there is more than
645 one viewer controlled by a scene handler, after a ClearStore on the
646 scene handler, e.g., with /vis/scene/notifyHandlers, the first
647 viewer to get refreshed should trigger the display list rebuild, but
648 the second need not. However, when the second viewer's turn comes,
649 the display lists are there, and are called, e.g.,
650 G4OpenGLStoredXViewer::DrawView calls
651 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
652 nothing appears on the screen. To overcome this there is some
653 temporary code in G4VViewer::NeedKernelVisit which marks *all*
654 viewers to force a rebuild. To see the symptoms, comment out that
655 temporary code and issue these commands:
656 /vis/verbose c
657 /control/verbose 2
658 /vis/scene/create
659 /vis/scene/add/volume
660 /vis/sceneHandler/create OGLSX
661 /vis/viewer/create ! ! 1
662 /run/beamOn
663 /vis/viewer/create ! ! 1
664 /vis/viewer/select viewer-0
665 /vis/viewer/viewpointThetaPhi 20 20
666 /vis/viewer/select viewer-1
667 /vis/viewer/viewpointThetaPhi 40 40
668 /vis/viewer/set/style surface
669 /vis/viewer/refresh
670 /vis/viewer/select viewer-0
671 /vis/viewer/refresh
672 /vis/viewer/select viewer-1
673 /vis/viewer/set/style wireframe
674 /vis/scene/notifyHandlers
675 You may have to do this too:
676 /vis/viewer/select viewer-0
677 /vis/scene/notifyHandlers
678 One of the viewers is empty. Curious!!
679
6809th August 2001 John Allison (vis-V03-02-10-00)
681- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
682- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
683 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
684 picked up by inheritance anyway.
685- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
686- Corrected order of calling base class functions in
687 G4OpenGLStoredSceneHandler::Begin/EndModeling.
688
68924th July 2001 John Allison (vis-V03-02-06)
690- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
691
69214th July 2001 John Allison (opengl-V03-02-00)
693- Fixed crash in optimised mode: added Initialise() to viewers so
694 that windows are opened after viewers are fully constructed.
695
6962nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
697- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
698
6997th March 2001 John Allison
700- Changed char* to const char* in many places and that gave problems in
701 calls to Xt and Xm. Hope all's OK. Differences:
702 cvs diff -r vis-V03-00-06 vis-V03-00-07
703
70425th January 2001 John Allison (opengl-V03-00-00)
705- Implemented running re-calculation of up-vector in the case of "object
706 rotation" (lights move with camera) to prevent "flipping" of view when
707 camera passes through up-vector. Note that the default is "camera
708 rotation" (lights do not move with camera, i.e., remain fixed relative
709 to object) so the default is that this "flipping" can happen. To set
710 "object rotation" (lights move with camera) use
711 /vis/lights/move_with_camera true (soon to be
712 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
713 on Rotation Panel in OpenGLXm mode.
714- Changed some objects to references for efficiency. E.g.:
715 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
716
71722nd May 2000 John Allison (opengl-V01-01-00)
718- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
719 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
720 static XVisualInfo* vi_single_buffer;
721 static XVisualInfo* vi_double_buffer;
722- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
723 G4OpenGLXViewer.
724- Protected double deletion of window in destructors of G4OpenGLXmViewer
725 and G4OpenGLXViewer (Guy Barrand).
726- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
727- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
728 constructors.
Note: See TracBrowser for help on using the repository browser.
