15421st August 2007 John Allison (opengl-V09-00-00)
155- Removed redundant G4OpenGLXViewerMessenger.
156
15725th May 2007 John Allison (opengl-V08-03-03)
158- G4OpenGLSceneHandler and G4OpenGLXViewerMessenger:
159 Fixed gcc-4.1.2 compiler warnings.
160
16125th May 2007 John Allison (opengl-V08-03-02)
162- G4OpenGLXViewer: Trapped glXMakeCurrent in Initialise function.
163
16424th May 2007 John Allison (opengl-V08-03-01)
165- Fixes for SUN.
166
16716th May 2007 John Allison (opengl-V08-03-00)
168- Fix compiler warnings on SLC4.
169- Bug fixes:
170 o Correct path /vis/ogl/set/printMode.
171 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
172 and "/vis/ogl/printEPS").
173
1748th May 2007 John Allison (opengl-V08-02-06)
175- Moved vectored PostScript printing to G4OpenGLViewer.
176- /vis/ogl/printEPS should work for all viewers, including Win32.
177- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
178 effective on X windows (and still somewhat buggy).
179
1804th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
181- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
182 for OGL*Win32. Still doesn't work for OGL*Xm.
183
1843rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
185- G4OpenGLStoredSceneHandler:
186 o Re-organised display lists on a per-primitive basis, i.e., one
187 display list per primitive. (This is so that, except for text,
188 the colour - or, rather, intensity - can be brought out of the
189 display list into the TOList (Transient Object List) and
190 controlled for the Display-by-Time feature. Previously, if more
191 than one primitive were drawn between BeginPrimitives and
192 EndPrimitives, it would finish up all in one display list, colour
193 commands included. Rationalises and fixes a rare bug in the
194 Display-by-Time feature - see August 2006.)
195 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
196 one primoitive to fit with the above re-organisation.
197- Implemented picking for OGLIX.
198
19925th March 2007 John Allison (opengl-V08-02-03)
200- Fix compiler warnings.
201
2028th February 2007 John Allison (opengl-V08-02-02)
203- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
204- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
205 .but not switched back. Not serious, because context was always set
206 before normal drawing.)
207
2089th January 2007 John Allison (opengl-V08-02-01)
209- Implemented bitmap markers for MarkerSizeType == screen. (The old
210 polygon implementation remains for MarkerSizeType == world.)
211- Added G4OpenGLBitMapStore to assist the above.
212- G4OpenGLXViewer::CreateGLXContext:
213 o Bug fix: Added missing break in colormap lookup routine.
214
2155th January 2007 John Allison (opengl-V08-02-00)
216- G4OpenGLSceneHandler.cc:
217 o Followed change of signature of GetLineWidth in visman-V08-02-00.
218 o Minor efficiency improvements.
219
22021st November 2006 John Allison (opengl-V08-01-09)
221- Fixed compiler warnings.
222
2231st November 2006 John Allison (opengl-V08-01-08)
224- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
225 actually initiates a print, rather than set a flag for printing.
226
22724th October 2006 John Allison (opengl-V08-01-07)
228- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
229- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
230
23119th September 2006 John Allison (opengl-V08-01-06)
232- Added time origin for light front.
233- Added /vis/ogl/set/transparency.
234- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
235
2364th September 2006 John Allison (opengl-V08-01-05)
237- Implement cutaways.
238- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
239 primitives (see detector being drawn).
240- /vis/oglx/set/printEPS: change parameter default to true.
241
24230th August 2006 John Allison (opengl-V08-01-04)
243- G4OpenGLSceneHandler:
244 o Implemented line width.
245 o Switched off back face culling when clipping so that the inside of
246 volumes can be seen.
247 o Added CreateSection/CutawayPolyhedron to exploit generic
248 sectioning (DCUT) and cutaways. Currently not activated due to
249 instabilities in BooleanProcessor. Local sectioning still active
250 but broken (at least on Mac) due to apparent change in effect of
251 clipping planes (polyhedron edges not reconstructed).
252 o Rationalised calculation of marker size.
253- G4OpenGLStoredSceneHandler:
254 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
255 o Pick up time range from G4VisAttributes.
256- G4OpenGLViewer(Messenger):
257 o Added position and colour to /vis/ogl/set/displayHeadTime.
258 o Added /vis/ogl/set/displayLightFront.
259- G4OpenGLStoredViewer.cc:
260 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
261 o Added position and colour to DisplayHeadTime.
262 o Added DisplayLightFront.
263
26416th August 2006 John Allison (opengl-V08-01-03)
265- Corrected Solaris compilation error.
266- Added /vis/ogl/set/fade and displayHeadTime.
267
26814th August 2006 John Allison (opengl-V08-01-02)
269- Needs visman-V08-01-02.
270- G4OpenGLStored: Implemented display-by-time. Only available in
271 stored mode at present. Only implemented for circle, square,
272 polyline and polymarker at present, enough for currently available
273 trajectory models. Time is communicated via G4AttValues.
274- Added G4OpenGLViewerMessenger.
275- Added /vis/ogl/set/startTime and endTime of displayed objects.
276- All factories: Instantiated G4OpenGLViewerMessenger.
277- G4OpenGLViewer: Added fStart/EndTime.
278- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
279 spewPrimitiveEPS and spewSortedFeedback.
280
28117th July John Allison (opengl-V08-01-01)
282- Added /vis/oglx/set/printEPS (prints eps file on every update).
283
2843rd July 2006 John Allison (opengl-V08-01-00)
285- Elimination of redundant variable doublebuffer and implementation of
286 FinishView in all viewers.
287
28830th May 2006 Joseph Perl (opengl-V08-00-08)
289- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
290 variable seems to have random behavior and should be assumed false for
291 this viewer.
292
29329th May 2006 Joseph Perl (opengl-V08-00-07)
294- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
295 Removed common FinishView and instead made separate FinishView for the two different
296 versions of this viewer since each wants a different buffer swapping behaviour.
297
29812th May 2006 John Allison (opengl-V08-00-06)
299- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
300
30128th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
302- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
303 recomputing transients.
304
30524th April 2006 John Allison (opengl-V08-00-04)
306- Fixed compilation problem on Windows.
307
30819th April 2006 John Allison (opengl-V08-00-03)
309- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
310 G4OpenGLImmediateSceneHandler:
311 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
312 greps-V08-00-02).
313 o Migrated to direct access to G4PhysicalVolumeModel.
314- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
315 of display lists in DrawView.
316
31714th March 2006 John Allison (opengl-V08-00-02)
318- Refined display list building and re-drawing algorithm.
319 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
320 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
321- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
322 re-use algorithm. In test19 with global culling off, numbers of
323 display lists used are:
324 o 191 No re-use:
325 o 73 Before this change: re-use except replicas (includes parameterised).
326 o 33 After this change: re-use except parameterised and replicas in radius.
327
32826th January 2006 John Allison (opengl-V08-00-01)
329- Coworks with visman-V08-00-04 (removed fModified).
330- Removed references to fModified.
331- Tidying: Removed unnecessary ClearView.
332- G4OpenGLSceneHandler.cc: Added some (commented out) code for
333 possible future implementation of 2D drawing.
334- G4OpenGLXViewer.cc: Improved exception printing.
335
33611th January 2006 John Allison (opengl-V08-00-00)
337- Improved efficiency: all DrawView's:
338 o Don't call ClearView.
339 o Set flag so SetView will not be called in ProcessView.
340 o Leave background colour to ClearView.
341- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
342- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
343 for current viewer.
344
34524th November 2005 John Allison (opengl-V07-01-09)
346- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
347
34822nd November 2005 John Allison (opengl-V07-01-08)
349- Added G4OpenGLXmViewerMessenger.
350- Corrected text position.
351- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
352
35317th November 2005 Gabriele Cosmo
354- Fixed settings of background style for WIN32 viewers.
355
35613th November 2005 John Allison (opengl-V07-01-07)
357- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
358
35913th October 2005 John Allison (opengl-V07-01-06)
360- Allowed any colour background.
361- Implemented non-uniform scaling.
362- Migration to <sstream>.
363
36429th September 2005 John Allison (opengl-V07-01-05)
365- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
366 scene handler.
367- Re-implemented transparency button in OpenGLXm.
368
36913th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
370- Implemented white background for all OGL viewers.
371- G4OpenGLSceneHandler.cc:
372 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
373 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
374 o Corrected GetTextColour(text).
375 o Corrected GetColour(polyhedron).
376
3775th September 2005 John Allison (opengl-V07-01-03)
378- Bug fix: stored transparent objects were being lost.
379
3802nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
381- Bug fix: edgeflags problem introduced with smooth shading in
382 opengl-V07-01-00.
383- Implementation of a "better algorithm" for the rendering of
384 transparent polyhedron objects. It renders all opaque objects
385 first, then renders the transparent objects with the depth buffer in
386 read-only mode (see OpenGL Programming Guide). It uses the new
387 facility in G4VSceneHandler::ProcessScene for an optional second pass
388 of the run-duration models in the scene. Note this algorithm is
389 still only an approximation. It will still give the wrong blended
390 colour if two transparent objects are rendered front first. For
391 nested transparent objects, this is unfortunate, because
392 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
393 in such a way that mothers come first. Also, there is no guaranteed
394 relationship between the order of rendering and the depth of two
395 transparent objects if they are at the same level or in different
396 branches of the hierarchy. Still, the only error will be an
397 incorrect colour - the objects will still give the appearance of
398 transparency, so it's a pretty good algorithm. (An even better
399 algorithm would be to attempt to render the facets in depth order,
400 deepest first. But how do you calculate the depth - centre of area,
401 deepest corner? One can still imagine pathalogical cases that would
402 sometimes give the wrong colour. Also, for stored mode, the order
403 is fixed in a display list so when the user rotates the view, one
404 would lose the depth ordering. I think we have to accept that
405 blending in OpenGL is only ever an approximation. For accurate
406 blending, use RayTracer.)
407
40828th August 2005 John Allison (opengl-V07-01-01)
409- Half-way implementation of rendering of transparent polyhedron
410 objects. In this implementation, no account is taken of the order
411 of rendering. Transparent objects are rendered with depth testing
412 off so that objects behind can still be seen. But this means that
413 opaque objects in front do not obscure them - and they jolly well
414 should! A better algorithm is to render all opaque objects first,
415 then render the transparent objects with the depth buffer in
416 read-only mode (see OpenGL Programming Guide). This is going to
417 take a little more thought - see opengl-V07-01-02.
418
41920th July 2005 John Allison (opengl-V07-01-00)
420- Introduced smooth shading, taking advantage of hitherto un-noticed
421 feature of HepPolyhedron::GetNextFacet that calculates the normals
422 at each vertex so that curved surfaces are rendered more
423 realistically (Gouraud shading).
424- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
425- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
426 the default window size. It used to be 400x400, hardcoded in
427 G4OpenGLXmViewer.cc, but now it picks up the
428 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
429 The user may change it on the command line, e.g:
430 /vis/open OGLSXm 500
431 or
432 /vis/viewer/create ! ! 500
433
43430th May 2005 John Allison (opengl-V07-00-03)
435- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
436 map of vectors in G4OpenGLFontBaseStore.)
437
4384th May 2005 John Allison (opengl-V07-00-02)
439- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
440 was taken out to prevent recursive calling, but that seems to be OK,
441 and it is needed to implement refresh at end of event/run.)
442
44322nd April 2005 John Allison (opengl-V07-00-01)
444- Rationalised work of opengl-V07-00-00. Functionality unchanged.
445 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
446 o In all concrete viewers, added call to CreateFontLists().
447 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
448 o There is no longer a need to implement in the XmViewer, since it
449 now inherits. Thus the font code now only appears once for X.
450 o Awaiting implementation for WIN32.
451
45217th April 2005 John Allison (opengl-V07-00-00)
453- Based on vis-V07-00-13.
454- Implemented text for X-Windows viewers. Uses glXUseXFont, which
455 creates display lists for nominated fonts. Simple-minded scheme in
456 which each viewer creates its own font display lists for a variety
457 of sizes, which are accessed by the scene handler through a new
458 class, G4OpenGLFontBaseStore. Affected methods:
459 G4OpenGLXViewer::CreateMainWindow()
460 G4OpenGLXmViewer::CreateMainWindow()

462
46318th November 2004 John Allison (opengl-V06-02-07)
464- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
465
46615th November 2004 Guy Barrand
467- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
468 to see trajectories (for example with N03). Correct so that
469 ShowView do a FinishView that does : glFlush, wglSwapBuffer
470 and empty the Windows message queue.
471
47222nd September 2004 John Allison (opengl-V06-02-06)
473- doxygen output to tmp area.
474- Trap non-regular polyhedrons.
475
47613th September 2004 Gabriele Cosmo (opengl-V06-02-05)
477- G4OpenGLTransform3D.cc: simplified implementation for GetMatrix()
478 to allow for porting on CLHEP-1.9.X series.
479
48023rd July 2004 John Allison
481- Draws auxiliary edges if required.

494- Fixed long-standing problem with hidden line removal.
495- Improved messages on failure to get visual.
496- Added GLX_STENCIL_SIZE explicit request to visual attributes - most
497 systems provided by default anyway, so no effect.
498
4991st July 2004 John Allison (opengl-V06-02-00)
500- Rationalised G4OpenGLSceneHandler ready for hidden line removal.
501- Bug fix in G4OpenGLXmPanningCallbacks.cc for dolly control.

506- GNUmakefile and disclaimer changes - see visualization/History.
507
5089th April 2004 John Allison (vis-V06-01-01 + interfaces-V06-01-00)
509- Tagged OpenGL as below. Joint with interfaces-V06-01-00.
510
5117th April 2004 Guy Barrand
512- visualization/OpenGL/* : use the G4OpenGL.hh file.
513- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
514 the include of gl/gl.h and gl/glu.h that may be platform dependant.
515 It permits to rm some #ifdef WIN32 spread in the code. It opens also
516 the way to the usage of the Apple OpenGL on a Mac.
517
51817th February 2004 John Allison (opengl-V06-00-00)
519- Fixed bug #581: wrong order of statements in
520 G4OpenGLXViewer::~G4OpenGLXViewer (see bug report).
521
5224th October 2003 Gabriele Cosmo (vis-V05-02-01)
523- GNUmakefile:
524 o replaced "digits+hits" with "digits_hits".
525- Coworks with "geometry-V05-02-00" and "digits_hits-V05-02-00".
526
52722nd September 2003 John Allison (vis-V05-02-00, greps-V05-02-00)

542 o G4OpenGLWin32Viewer[.hh.cc]: removed inclusion of <GL/glx.h>.
543 o G4OpenGLViewer.cc: replaced local variables near/far with pnear/pfar
544 since declared 'obsolete' in WIN32 platforms.
545
54627th November 2002 John Allison (vis-V04-01-08)

57224th August 2001 John Allison (vis-V03-02-13)
573- Limited the printing of warnings in
574 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
575
57614th August 2001 John Allison (vis-V03-02-11)
577- Improved KernelVisitDecision.
578- Fixed a few small bugs in multiple "stored" viewers, but see next item.
579- There's an outstanding bug in OpenGL Stored. If there is more than
580 one viewer controlled by a scene handler, after a ClearStore on the
581 scene handler, e.g., with /vis/scene/notifyHandlers, the first
582 viewer to get refreshed should trigger the display list rebuild, but
583 the second need not. However, when the second viewer's turn comes,
584 the display lists are there, and are called, e.g.,
585 G4OpenGLStoredXViewer::DrawView calls
586 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
587 nothing appears on the screen. To overcome this there is some
588 temporary code in G4VViewer::NeedKernelVisit which marks *all*
589 viewers to force a rebuild. To see the symptoms, comment out that
590 temporary code and issue these commands:
591 /vis/verbose c
592 /control/verbose 2
593 /vis/scene/create
594 /vis/scene/add/volume
595 /vis/sceneHandler/create OGLSX
596 /vis/viewer/create ! ! 1
597 /run/beamOn
598 /vis/viewer/create ! ! 1
599 /vis/viewer/select viewer-0
600 /vis/viewer/viewpointThetaPhi 20 20
601 /vis/viewer/select viewer-1
602 /vis/viewer/viewpointThetaPhi 40 40
603 /vis/viewer/set/style surface
604 /vis/viewer/refresh
605 /vis/viewer/select viewer-0
606 /vis/viewer/refresh
607 /vis/viewer/select viewer-1
608 /vis/viewer/set/style wireframe
609 /vis/scene/notifyHandlers
610 You may have to do this too:
611 /vis/viewer/select viewer-0
612 /vis/scene/notifyHandlers
613 One of the viewers is empty. Curious!!
614
6159th August 2001 John Allison (vis-V03-02-10-00)
616- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
617- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
618 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
619 picked up by inheritance anyway.
620- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
621- Corrected order of calling base class functions in
622 G4OpenGLStoredSceneHandler::Begin/EndModeling.
623
62424th July 2001 John Allison (vis-V03-02-06)
625- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
626
62714th July 2001 John Allison (opengl-V03-02-00)
628- Fixed crash in optimised mode: added Initialise() to viewers so
629 that windows are opened after viewers are fully constructed.
630
6312nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
632- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
633
6347th March 2001 John Allison
635- Changed char* to const char* in many places and that gave problems in
636 calls to Xt and Xm. Hope all's OK. Differences:
637 cvs diff -r vis-V03-00-06 vis-V03-00-07
638
63925th January 2001 John Allison (opengl-V03-00-00)
640- Implemented running re-calculation of up-vector in the case of "object
641 rotation" (lights move with camera) to prevent "flipping" of view when
642 camera passes through up-vector. Note that the default is "camera
643 rotation" (lights do not move with camera, i.e., remain fixed relative
644 to object) so the default is that this "flipping" can happen. To set
645 "object rotation" (lights move with camera) use
646 /vis/lights/move_with_camera true (soon to be
647 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
648 on Rotation Panel in OpenGLXm mode.
649- Changed some objects to references for efficiency. E.g.:
650 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
651
65222nd May 2000 John Allison (opengl-V01-01-00)
653- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
654 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
655 static XVisualInfo* vi_single_buffer;
656 static XVisualInfo* vi_double_buffer;
657- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
658 G4OpenGLXViewer.
659- Protected double deletion of window in destructors of G4OpenGLXmViewer
660 and G4OpenGLXViewer (Guy Barrand).
661- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
662- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
663 constructors.
