149
15021st August 2007 John Allison (opengl-V09-00-00)
151- Removed redundant G4OpenGLXViewerMessenger.
152
15325th May 2007 John Allison (opengl-V08-03-03)
154- G4OpenGLSceneHandler and G4OpenGLXViewerMessenger:
155 Fixed gcc-4.1.2 compiler warnings.
156
15725th May 2007 John Allison (opengl-V08-03-02)
158- G4OpenGLXViewer: Trapped glXMakeCurrent in Initialise function.
159
16024th May 2007 John Allison (opengl-V08-03-01)
161- Fixes for SUN.
162
16316th May 2007 John Allison (opengl-V08-03-00)
164- Fix compiler warnings on SLC4.
165- Bug fixes:
166 o Correct path /vis/ogl/set/printMode.
167 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
168 and "/vis/ogl/printEPS").
169
1708th May 2007 John Allison (opengl-V08-02-06)
171- Moved vectored PostScript printing to G4OpenGLViewer.
172- /vis/ogl/printEPS should work for all viewers, including Win32.
173- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
174 effective on X windows (and still somewhat buggy).
175
1764th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
177- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
178 for OGL*Win32. Still doesn't work for OGL*Xm.
179
1803rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
181- G4OpenGLStoredSceneHandler:
182 o Re-organised display lists on a per-primitive basis, i.e., one
183 display list per primitive. (This is so that, except for text,
184 the colour - or, rather, intensity - can be brought out of the
185 display list into the TOList (Transient Object List) and
186 controlled for the Display-by-Time feature. Previously, if more
187 than one primitive were drawn between BeginPrimitives and
188 EndPrimitives, it would finish up all in one display list, colour
189 commands included. Rationalises and fixes a rare bug in the
190 Display-by-Time feature - see August 2006.)
191 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
192 one primoitive to fit with the above re-organisation.
193- Implemented picking for OGLIX.
194
19525th March 2007 John Allison (opengl-V08-02-03)
196- Fix compiler warnings.
197
1988th February 2007 John Allison (opengl-V08-02-02)
199- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
200- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
201 .but not switched back. Not serious, because context was always set
202 before normal drawing.)
203
2049th January 2007 John Allison (opengl-V08-02-01)
205- Implemented bitmap markers for MarkerSizeType == screen. (The old
206 polygon implementation remains for MarkerSizeType == world.)
207- Added G4OpenGLBitMapStore to assist the above.
208- G4OpenGLXViewer::CreateGLXContext:
209 o Bug fix: Added missing break in colormap lookup routine.
210
2115th January 2007 John Allison (opengl-V08-02-00)
212- G4OpenGLSceneHandler.cc:
213 o Followed change of signature of GetLineWidth in visman-V08-02-00.
214 o Minor efficiency improvements.
215
21621st November 2006 John Allison (opengl-V08-01-09)
217- Fixed compiler warnings.
218
2191st November 2006 John Allison (opengl-V08-01-08)
220- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
221 actually initiates a print, rather than set a flag for printing.
222
22324th October 2006 John Allison (opengl-V08-01-07)
224- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
225- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
226
22719th September 2006 John Allison (opengl-V08-01-06)
228- Added time origin for light front.
229- Added /vis/ogl/set/transparency.
230- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
231
2324th September 2006 John Allison (opengl-V08-01-05)
233- Implement cutaways.
234- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
235 primitives (see detector being drawn).
236- /vis/oglx/set/printEPS: change parameter default to true.
237
23830th August 2006 John Allison (opengl-V08-01-04)
239- G4OpenGLSceneHandler:
240 o Implemented line width.
241 o Switched off back face culling when clipping so that the inside of
242 volumes can be seen.
243 o Added CreateSection/CutawayPolyhedron to exploit generic
244 sectioning (DCUT) and cutaways. Currently not activated due to
245 instabilities in BooleanProcessor. Local sectioning still active
246 but broken (at least on Mac) due to apparent change in effect of
247 clipping planes (polyhedron edges not reconstructed).
248 o Rationalised calculation of marker size.
249- G4OpenGLStoredSceneHandler:
250 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
251 o Pick up time range from G4VisAttributes.
252- G4OpenGLViewer(Messenger):
253 o Added position and colour to /vis/ogl/set/displayHeadTime.
254 o Added /vis/ogl/set/displayLightFront.
255- G4OpenGLStoredViewer.cc:
256 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
257 o Added position and colour to DisplayHeadTime.
258 o Added DisplayLightFront.
259
26016th August 2006 John Allison (opengl-V08-01-03)
261- Corrected Solaris compilation error.
262- Added /vis/ogl/set/fade and displayHeadTime.
263
26414th August 2006 John Allison (opengl-V08-01-02)
265- Needs visman-V08-01-02.
266- G4OpenGLStored: Implemented display-by-time. Only available in
267 stored mode at present. Only implemented for circle, square,
268 polyline and polymarker at present, enough for currently available
269 trajectory models. Time is communicated via G4AttValues.
270- Added G4OpenGLViewerMessenger.
271- Added /vis/ogl/set/startTime and endTime of displayed objects.
272- All factories: Instantiated G4OpenGLViewerMessenger.
273- G4OpenGLViewer: Added fStart/EndTime.
274- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
275 spewPrimitiveEPS and spewSortedFeedback.
276
27717th July John Allison (opengl-V08-01-01)
278- Added /vis/oglx/set/printEPS (prints eps file on every update).
279
2803rd July 2006 John Allison (opengl-V08-01-00)
281- Elimination of redundant variable doublebuffer and implementation of
282 FinishView in all viewers.
283
28430th May 2006 Joseph Perl (opengl-V08-00-08)
285- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
286 variable seems to have random behavior and should be assumed false for
287 this viewer.
288
28929th May 2006 Joseph Perl (opengl-V08-00-07)
290- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
291 Removed common FinishView and instead made separate FinishView for the two different
292 versions of this viewer since each wants a different buffer swapping behaviour.
293
29412th May 2006 John Allison (opengl-V08-00-06)
295- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
296
29728th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
298- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
299 recomputing transients.
300
30124th April 2006 John Allison (opengl-V08-00-04)
302- Fixed compilation problem on Windows.
303
30419th April 2006 John Allison (opengl-V08-00-03)
305- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
306 G4OpenGLImmediateSceneHandler:
307 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
308 greps-V08-00-02).
309 o Migrated to direct access to G4PhysicalVolumeModel.
310- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
311 of display lists in DrawView.
312
31314th March 2006 John Allison (opengl-V08-00-02)
314- Refined display list building and re-drawing algorithm.
315 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
316 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
317- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
318 re-use algorithm. In test19 with global culling off, numbers of
319 display lists used are:
320 o 191 No re-use:
321 o 73 Before this change: re-use except replicas (includes parameterised).
322 o 33 After this change: re-use except parameterised and replicas in radius.
323
32426th January 2006 John Allison (opengl-V08-00-01)
325- Coworks with visman-V08-00-04 (removed fModified).
326- Removed references to fModified.
327- Tidying: Removed unnecessary ClearView.
328- G4OpenGLSceneHandler.cc: Added some (commented out) code for
329 possible future implementation of 2D drawing.
330- G4OpenGLXViewer.cc: Improved exception printing.
331
33211th January 2006 John Allison (opengl-V08-00-00)
333- Improved efficiency: all DrawView's:
334 o Don't call ClearView.
335 o Set flag so SetView will not be called in ProcessView.
336 o Leave background colour to ClearView.
337- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
338- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
339 for current viewer.
340
34124th November 2005 John Allison (opengl-V07-01-09)
342- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
343
34422nd November 2005 John Allison (opengl-V07-01-08)
345- Added G4OpenGLXmViewerMessenger.
346- Corrected text position.
347- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
348
34917th November 2005 Gabriele Cosmo
350- Fixed settings of background style for WIN32 viewers.
351
35213th November 2005 John Allison (opengl-V07-01-07)
353- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
354
35513th October 2005 John Allison (opengl-V07-01-06)
356- Allowed any colour background.
357- Implemented non-uniform scaling.
358- Migration to <sstream>.
359
36029th September 2005 John Allison (opengl-V07-01-05)
361- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
362 scene handler.
363- Re-implemented transparency button in OpenGLXm.
364
36513th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
366- Implemented white background for all OGL viewers.
367- G4OpenGLSceneHandler.cc:
368 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
369 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
370 o Corrected GetTextColour(text).
371 o Corrected GetColour(polyhedron).
372
3735th September 2005 John Allison (opengl-V07-01-03)
374- Bug fix: stored transparent objects were being lost.
375
3762nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
377- Bug fix: edgeflags problem introduced with smooth shading in
378 opengl-V07-01-00.
379- Implementation of a "better algorithm" for the rendering of
380 transparent polyhedron objects. It renders all opaque objects
381 first, then renders the transparent objects with the depth buffer in
382 read-only mode (see OpenGL Programming Guide). It uses the new
383 facility in G4VSceneHandler::ProcessScene for an optional second pass
384 of the run-duration models in the scene. Note this algorithm is
385 still only an approximation. It will still give the wrong blended
386 colour if two transparent objects are rendered front first. For
387 nested transparent objects, this is unfortunate, because
388 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
389 in such a way that mothers come first. Also, there is no guaranteed
390 relationship between the order of rendering and the depth of two
391 transparent objects if they are at the same level or in different
392 branches of the hierarchy. Still, the only error will be an
393 incorrect colour - the objects will still give the appearance of
394 transparency, so it's a pretty good algorithm. (An even better
395 algorithm would be to attempt to render the facets in depth order,
396 deepest first. But how do you calculate the depth - centre of area,
397 deepest corner? One can still imagine pathalogical cases that would
398 sometimes give the wrong colour. Also, for stored mode, the order
399 is fixed in a display list so when the user rotates the view, one
400 would lose the depth ordering. I think we have to accept that
401 blending in OpenGL is only ever an approximation. For accurate
402 blending, use RayTracer.)
403
40428th August 2005 John Allison (opengl-V07-01-01)
405- Half-way implementation of rendering of transparent polyhedron
406 objects. In this implementation, no account is taken of the order
407 of rendering. Transparent objects are rendered with depth testing
408 off so that objects behind can still be seen. But this means that
409 opaque objects in front do not obscure them - and they jolly well
410 should! A better algorithm is to render all opaque objects first,
411 then render the transparent objects with the depth buffer in
412 read-only mode (see OpenGL Programming Guide). This is going to
413 take a little more thought - see opengl-V07-01-02.
414
41520th July 2005 John Allison (opengl-V07-01-00)
416- Introduced smooth shading, taking advantage of hitherto un-noticed
417 feature of HepPolyhedron::GetNextFacet that calculates the normals
418 at each vertex so that curved surfaces are rendered more
419 realistically (Gouraud shading).
420- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
421- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
422 the default window size. It used to be 400x400, hardcoded in
423 G4OpenGLXmViewer.cc, but now it picks up the
424 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
425 The user may change it on the command line, e.g:
426 /vis/open OGLSXm 500
427 or
428 /vis/viewer/create ! ! 500
429
43030th May 2005 John Allison (opengl-V07-00-03)
431- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
432 map of vectors in G4OpenGLFontBaseStore.)
433
4344th May 2005 John Allison (opengl-V07-00-02)
435- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
436 was taken out to prevent recursive calling, but that seems to be OK,
437 and it is needed to implement refresh at end of event/run.)
438
43922nd April 2005 John Allison (opengl-V07-00-01)
440- Rationalised work of opengl-V07-00-00. Functionality unchanged.
441 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
442 o In all concrete viewers, added call to CreateFontLists().
443 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
444 o There is no longer a need to implement in the XmViewer, since it
445 now inherits. Thus the font code now only appears once for X.
446 o Awaiting implementation for WIN32.
447
44817th April 2005 John Allison (opengl-V07-00-00)
449- Based on vis-V07-00-13.
450- Implemented text for X-Windows viewers. Uses glXUseXFont, which
451 creates display lists for nominated fonts. Simple-minded scheme in
452 which each viewer creates its own font display lists for a variety
453 of sizes, which are accessed by the scene handler through a new
454 class, G4OpenGLFontBaseStore. Affected methods:
455 G4OpenGLXViewer::CreateMainWindow()
456 G4OpenGLXmViewer::CreateMainWindow()
457 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)

45918th November 2004 John Allison (opengl-V06-02-07)
460- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
461
46215th November 2004 Guy Barrand
463- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
464 to see trajectories (for example with N03). Correct so that
465 ShowView do a FinishView that does : glFlush, wglSwapBuffer
466 and empty the Windows message queue.
467
46822nd September 2004 John Allison (opengl-V06-02-06)
469- doxygen output to tmp area.
470- Trap non-regular polyhedrons.
471
47213th September 2004 Gabriele Cosmo (opengl-V06-02-05)
473- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
474 to allow for porting on CLHEP-1.9.X series.
475
47623rd July 2004 John Allison
477- Draws auxiliary edges if required.
478- Added auxiliary edge button.

481- Refinements to hidden line, hidden surface removal.
482
48314th July 2004 John Allison (opengl-V06-02-03)
484- Removed superfluous #include "G4VisManager.hh" from G4OpenGLXmViewer.cc.

490- Fixed long-standing problem with hidden line removal.
491- Improved messages on failure to get visual.
492- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
493 systems provided by default anyway, so no effect.
494
4951st July 2004 John Allison (opengl-V06-02-00)
496- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
497- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.

5017th June 2004 Gabriele Cosmo (vis-V06-01-02)
502- GNUmakefile and disclaimer changes - see visualization/History.
503
5049th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
505- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
506
5077th April 2004 Guy Barrand
508- visualization/OpenGL/* : use the G4OpenGL.hh file.
509- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
510 the include of gl/gl.h and gl/glu.h that may be platform dependant.
511 It permits to rm some #ifdef WIN32 spread in the code. It opens also
512 the way to the usage of the Apple OpenGL on a Mac.
513
51417th February 2004 John Allison (opengl-V06-00-00)
515- Fixed bug #581: wrong order of statements in
516 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
517
5184th October 2003 Gabriele Cosmo (vis-V05-02-01)
519- GNUmakefile:
520 o replaced "digits+hits" with "digits_hits".
521- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".

538 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
539 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
540 since declared 'obsolete' in WIN32 platforms.
541
54227th November 2002 John Allison (vis-V04-01-08)

567
56824th August 2001 John Allison (vis-V03-02-13)
569- Limited the printing of warnings in
570 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
571
57214th August 2001 John Allison (vis-V03-02-11)
573- Improved KernelVisitDecision.
574- Fixed a few small bugs in multiple "stored" viewers, but see next item.
575- There's an outstanding bug in OpenGL Stored. If there is more than
576 one viewer controlled by a scene handler, after a ClearStore on the
577 scene handler, e.g., with /vis/scene/notifyHandlers, the first
578 viewer to get refreshed should trigger the display list rebuild, but
579 the second need not. However, when the second viewer's turn comes,
580 the display lists are there, and are called, e.g.,
581 G4OpenGLStoredXViewer::DrawView calls
582 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
583 nothing appears on the screen. To overcome this there is some
584 temporary code in G4VViewer::NeedKernelVisit which marks *all*
585 viewers to force a rebuild. To see the symptoms, comment out that
586 temporary code and issue these commands:
587 /vis/verbose c
588 /control/verbose 2
589 /vis/scene/create
590 /vis/scene/add/volume
591 /vis/sceneHandler/create OGLSX
592 /vis/viewer/create ! ! 1
593 /run/beamOn
594 /vis/viewer/create ! ! 1
595 /vis/viewer/select viewer-0
596 /vis/viewer/viewpointThetaPhi 20 20
597 /vis/viewer/select viewer-1
598 /vis/viewer/viewpointThetaPhi 40 40
599 /vis/viewer/set/style surface
600 /vis/viewer/refresh
601 /vis/viewer/select viewer-0
602 /vis/viewer/refresh
603 /vis/viewer/select viewer-1
604 /vis/viewer/set/style wireframe
605 /vis/scene/notifyHandlers
606 You may have to do this too:
607 /vis/viewer/select viewer-0
608 /vis/scene/notifyHandlers
609 One of the viewers is empty. Curious!!
610
6119th August 2001 John Allison (vis-V03-02-10-00)
612- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
613- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
614 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
615 picked up by inheritance anyway.
616- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
617- Corrected order of calling base class functions in
618 G4OpenGLStoredSceneHandler::Begin/EndModeling.
619
62024th July 2001 John Allison (vis-V03-02-06)
621- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
622
62314th July 2001 John Allison (opengl-V03-02-00)
624- Fixed crash in optimised mode: added Initialise() to viewers so
625 that windows are opened after viewers are fully constructed.
626
6272nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
628- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
629
6307th March 2001 John Allison
631- Changed char* to const char* in many places and that gave problems in
632 calls to Xt and Xm. Hope all's OK. Differences:
633 cvs diff -r vis-V03-00-06 vis-V03-00-07
634
63525th January 2001 John Allison (opengl-V03-00-00)
636- Implemented running re-calculation of up-vector in the case of "object
637 rotation" (lights move with camera) to prevent "flipping" of view when
638 camera passes through up-vector. Note that the default is "camera
639 rotation" (lights do not move with camera, i.e., remain fixed relative
640 to object) so the default is that this "flipping" can happen. To set
641 "object rotation" (lights move with camera) use
642 /vis/lights/move_with_camera true (soon to be
643 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
644 on Rotation Panel in OpenGLXm mode.
645- Changed some objects to references for efficiency. E.g.:
646 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
647
64822nd May 2000 John Allison (opengl-V01-01-00)
649- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
650 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
651 static XVisualInfo* vi_single_buffer;
652 static XVisualInfo* vi_double_buffer;
653- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
654 G4OpenGLXViewer.
655- Protected double deletion of window in destructors of G4OpenGLXmViewer
656 and G4OpenGLXViewer (Guy Barrand).
657- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
658- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
659 constructors.
