54 # History entries prior to 11.0
55
56 18 November 2021 John Allison (raytracer-V10-07-06)
57 - G4RayTracer.cc: Coverity fix: un-initialised data member.
58
59 12 November 2021 - Ben Morgan (raytracer-V10-07-05)
60 - Retire G4VIS_... preprocessor symbols in toolkit build, only required
61 by obsolete GNUmake system
62
63 25 October 2021 Guy Barrand (raytracer-V10-07-04)
64 - G4RayTracerSceneHandler.hh: to quiet g++ about "AddPrimitive(G4Plotter&)", have:
65 using G4VSceneHandler::AddPrimitive;
66
67 30 September 2021 John Allison (raytracer-V10-07-03)
68 - Remove instantiation of G4The(MT)RayTracer from G4RayTracer.
69 - G4RayTracer is/should be a "pure factory". Its job is to instantiate
70 a scene handler or viewer on request. G4The(MT)RayTracer should/need
71 only be instantiated when the viewer is instantiated.
72 - It is somewhat complicated by the need(?) for G4TheMTRayTracer to be
73 a singleton - is that really required? Cannot G4RTRun simply get the
74 current ray tracer? Anyway, singleton nature is preserved.
75
76 24 September 2021 John Allison (raytracer-V10-07-02)
77 - Make RayTracerX viewers "auto refresh".
78 - This means the ray tracer will start tracing immediately on opening
79 (`/vis/open RayTracerX`) and on any change of view parameters.
80 - In the past it was thought better to refresh manually, to give opportunity
81 of adjusting the view first, but with the introduction of using the
82 view parameters of the previously existing viewer (visman-V10-07-20),
83 it is easy to choose a view with an OpenGL viewer, say, then simply open
84 the ray tracer viewer.
85 - Also, with the advent of multithreading, ray tracing is faster, so
86 adjusting and re-viewing is less tedious.
87 - This only affects RayTracerX - plain RayTracer is not affected.
88 - You may switch this feature off with `/vis/viewer/set/auto-refresh false`.
89
90 30 June 2021 John Allison (raytracer-V10-07-01)
91 - Requires greps-V10-07-09, modeling-V10-07-11 and visman-V10-07-11.
92 - Revise vis models. See visualization/modeling/History for more details.
93 - Consequent changes:
94 o AddPrimitive(const G4Scale&) has been removed from all scene handlers.
95
96 15th April 2021 Ben Morgan (raytracer-V10-07-00)
97 - Migrate to modular CMake build
98
99 20th October 2020 Jonathan Madsen (raytracer-V10-06-03)
100 - Implemented G4RunManagerFactory::GetMasterRunManager()
101
102 10th August 2020 John Allison (raytracer-V10-06-02)
103 - G4TheMTRayTracer.cc:
104 o Suppress printing during RayTracer run. Keep current verbosity and
105 printProgress, then
106 G4UImanager::GetUIpointer()->ApplyCommand("/run/verbose 0");
107 G4UImanager::GetUIpointer()->ApplyCommand("/run/printProgress 0");
108 then restore after.
109
110 31 May 2020 Ben Morgan (raytracer-V10-06-01)
111 - Use add_definitions to set PRIVATE-level compile add_definitions
112 for compatibility between old and new CMake systems
113
114 12 December 2019 Ben Morgan (raytracer-V10-06-00)
115 - Cleanup CMake build, removing obsolete granular library option and
116 explicit include_directories.
117
118 15th November 2019, Gabriele Cosmo (raytracer-V10-05-01)
119 - Fixed cases of implicit type conversions from size_t to G4int.
120
121 25th October 2019 Ben Morgan (raytracer-V10-05-00)
122 - Link to X11 imported targets when building X11 driver
123
124 9th November 2018 Gabriele Cosmo (raytracer-V10-04-04)
125 - G4RTMessenger: fixed printout typos.
126
127 24th October 2018 John Allison (raytracer-V10-04-03)
128 - G4RayTracerSceneHandler::BuildVisAttsMap:
129 o Use name,copyNo constructor of G4ModelingParameters::PVPointerCopyNo.
130 (The nodeID constructor was removed in modeling-V10-04-15).
131
132 17th May 2018 Jonathan Madsen (raytracer-V10-04-01)
133 - updated "thread-local-static-var" model to
134 "function-returning-thread-local-static-reference" model
135 which fixes Windows DLL + MT
136
137 20th March 2018 Makoto Asai (raytracer-V10-04-00)
138 - G4RayTrajectory.cc
139 o Use HyperStep of G4ParallelWorldProcess to draw volumes
140 defined in a parallel world.
141 o sources.cmake and GNUmakefile are modified accordingly.
142
143 7th May 2017 John Allison (raytracer-V10-03-04)
144 - G4RayTracerViewer.cc:
145 o Expanded filename numbering to 4 digits, zero filled, e.g.,
146 g4RayTracer.viewer-1_0000.jpeg
147 g4RayTracer.viewer-1_0001.jpeg
148 etc.
149 o Useful for producing many files for a movie.
150
151 5th May 2017 John Allison (raytracer-V10-03-03)
152 - Pick up vis attributes of the geometry from the vis scene (G4Scene).
153 Make a map of the vis attributes by touchable path from the G4Scene in
154 G4RayTracerSceneHandler. When a touchable is encountered in the Ray
155 Tracer, pick up the vis attributes from the map instead of from the
156 geometry tree. For simple use, for example
157 /vis/open RayTracer # or RayTracerX
158 /vis/drawVolume
159 /vis/viewer/flush
160 the result will be the same as before. But when a user selects a
161 sub-component, for example
162 /vs/drawVolume Shape1
163 the Ray Tracer will now draw only Shape1. The Ray Tracer will also
164 follow changes made in other viewers by copying the view. For example
165 the user can chose a viewing angle and zoom, and change the visibility
166 and colour of volumes, using, say, a Qt viewer (say viewer-0), and see
167 the effect in the Ray Tracer:
168 /vis/open RayTracer # Gets the same scene as the Qt viewer
169 /vis/viewer/copyViewFrom viewer-0 # Copies camera parameters, or...
170 /vis/viewer/set/all viewer-0 # ...copies all parameters
171 /vis/viewerflush
172
173 19th February 2017 John Allison (raytracer-V10-03-02)
174 - G4RTXScanner.cc:
175 o Changed back to XA_RGB_BEST_MAP. (I don't know what was going on
176 but it seems OK now.)
177 - G4RayTracer.cc and G4RayTracerViewer.cc:
178 o The ray tracer pointer is now passed from G4RayTracer to
179 G4RayTracerViewer so that there is no need to instantiate it there.
180 This works for both sequential and MT modes. (G4RayTracerViewer.cc
181 no longer has any need for special action for G4MULTITHREADED - it
182 is all done in G4RayTracer.cc.)
183 o Introduced G4RayTracerViewer::Initialise. Fixes a bug whereby the
184 jpeg for RayTracer was always 600x600.
185
186 22nd February 2017 John Allison (raytracer-V10-03-00)
187 - G4RTXScanner.cc: Changed XA_RGB_BEST_MAP to XA_RGB_DEFAULT_MAP.
188 (It seems XA_RGB_BEST_MAP no longer available on Mac XQuartz 2.7.11.)
189
190 31st August 2016 John Allison (raytracer-V10-02-01)
191 - Fix G4Orb and G4Ellipsoid hiding warnings.
192

230
231 5th July 2012 Gabriele Cosmo (raytracer-V09-05-05)
232 - Explicitly use inclusion of headers for system of units and physical
233 constants, in plan to remove implicit inclusion from globals.hh.

240
241 8th June 2012 John Allison (raytracer-V09-05-02)
242 - Shadow clean.
243
244 8th February 2012 John Allison (raytracer-V09-05-01)
245 - G4RayTracerViewer.cc, G4TheRayTracer.hh/cc:
246 Adopt fix proposed by jasondet@gmail.com to fix Bug #1274.
247 - G4RayTracerViewer.cc:
248 o Move window size hints to constructor from SetView, so that
249 NColumn/Row are never changed, even if window size hints change
250 (e.g., as a result of /vis/viewer/set/all). It is not possible to
251 change NColumn/Row after instantiation.
252 - G4TheRayTracer.cc:
253 o Ensure unit vector for the ray shooter. (Otherwise it can cause a
254 G4Exception in G4ParticleChange::CheckIt.)
255
256 7th February 2012 John Allison (raytracer-V09-05-00)
257 - G4RayTracerViewer.cc:
258 o G4RayTracerViewer::SetView: Fix up-vector bug #1274.
259 o Move window size hints to constructor from SetView, so that
260 NColumn/Row are never changed, even if window size hints change
261 (e.g., as a result of /vis/viewer/set/all). It is not possible to
262 change NColumn/Row after instantiation.
263 - G4TheRayTracer.cc:
264 o Ensure unit vector for the ray shooter. (Otherwise it can cause a
265 G4Exception in G4ParticleChange::CheckIt.)
266
267 17th June 2011 Ben Morgan (raytracer-V09-04-04)
268 - sources.cmake : Changed to use GEANT4_USE_RAYTRACER_X11 variable.
269
270 24th May 2011 Ben Morgan (raytracer-V09-04-03)
271 - sources.cmake : Added additional includes, definitions and link libraries
272 to build X11 component of RayTracer, if it's enabled by the user.
273 CMake functionality added to trunk at revision 49996.
274
275 20th May 2011 Ben Morgan (raytracer-V09-04-02)
276 - CMakeLists.txt : Added G4VIS_ALLOC_EXPORT compiler definition via
277 add_definitions so it's applied to all sources in this module. We
278 don't add this definition at the visualization category level because
279 only raytracer uses it. It can be moved higher later.
280
281 2nd March 2011 John Allison (raytracer-V09-04-01)
282 - Fix bug introduced by fix to Coverity warnings.
283
284 1st March 2011 John Allison (raytracer-V09-04-00)
285 - G4RayTracerViewer::DrawView: Trap recursive calls, thus avoiding
286 warning messages for each pixel when endOfEventAction is "refresh".
287 EndOfEventAction is not relevant for Ray Tracer. At the present
288 time, Ray Tracer takes no notice of the scene. Perhaps in future,
289 it will, but G4RayTracerViewer should still ignore those recursive
290 calls.
291 - Fix Coverity warnings.
292
293 23, December L. Garnier
294 - GNUmakefile : Remove OpenGL/Qt stuff from Makefile
295
296 27th October 2010 Gabriele Cosmo (raytracer-V09-03-04)
297 - Restored DLL setup as originally. Withdrawn changes in last tag.
298
299 19th October 2010 Gabriele Cosmo (raytracer-V09-03-03)
300 - Replaced G4VIS_ALLOC_EXPORT flag with G4ALLOC_EXPORT for DLL exported
301 symbols.
302
303 14th June 2010 Gabriele Cosmo (raytracer-V09-03-02)
304 - Added missing virtual destructor to G4VRTScanner, G4RTXScanner and
305 G4RTSimpleScanner.
306
307 30th May 2010 John Allison (raytracer-V09-03-01)
308 - G4RayTracerSceneHandler: Added AddCompound(const G4VDigi&).
309
310 29th May 2010 John Allison (raytracer-V09-03-00)
311 - G4RayTrajectory.hh: Added DrawTrajectory() ready for i_mode migration.
312
313 15th November 2009 John Allison (raytracer-V09-02-02)
314 - Formal tag to record fixing of bugzilla Problem 1072.
315 o There is no change of source code.
316 o This was actullay fixed in raytracer-V09-02-00, which is already accepted.
317
318 21st October 2009 John Allison (raytracer-V09-02-01 coworks greps-V09-02-02)
319 - Added AddCompound (const G4THitsMap<G4double>&) methods.
320 o Prevents warnings about hiding - calls G4VSceneHandler base class.
321
322 16 September 2009 John Allison (raytracer-V09-02-00)
323 - Cosmetic adjustments and tagging.
324
325 19 August 2009 Laurent Garnier
326 - G4RayTracerViewer.cc, G4RayTracerXViewer.cc : Fix an bad use of fVP
327 parameters [bugzilla Problem 1072]
328

333 4th April 2008 John Allison (raytracer-V09-01-00)
334 - Fixed gcc-4.3.0 compiler warnings.
335
336 14th June 2007 John Allison (raytracer-V08-03-01)
337 - Fixed memory leak in G4RayTracer (wrapper class).
338
339 22nd May 2007 John Allison (raytracer-V08-03-00)
340 - Fixed for dubious ValGrind diagnostic showing apparent memory leak in
341 G4RTSimpleScanner and G4RTXScanner.

344 - Bug fix: use of window size hints.
345
346 17th November 2006 Joseph Perl (raytracer-V08-01-02)
347 - Deprecate /vis/rayTracer/backgroundColour.
348 - Hasn't worked for some time anyway.
349 - Users are instead referred to /vis/viewer/set/background.
350
351 14th November 2006 John Allison (raytracer-V08-01-01)
352 - Merged raytracer-V08-01-00-branch onto main branch.
353
354 11th November 2006 John Allison (raytracer-V08-01-00-00)
355 - Followed change to G4Scene.
356
357 14th August 2006 John Allison (raytracer-V08-01-00)
358 - G4RayTracerSceneHandler.cc: Added world to dummy scene to improve
359 robustness when under control of vis manager.
360
361 12th May 2006 John Allison (raytracer-V08-00-04)
362 - SetRecomputeTransients(false).

372 - G4TheRayTracer: Advance work for possible inclusion of
373 anti-aliasing. Currently no change of functionality.
374
375 11th January 2006 John Allison (raytracer-V08-00-00)
376 - Reorganisation (needs visman-V08-00-02):
377 o Allowed multiple ray tracers.
378 o Separated out the original ray tracer into G4TheRayTracer, to be
379 used by viewers.
380 o Made G4RTMessenger a smart singleton that queries the vis manager
381 for tracers.
382 o Caused G4RayTracer to instantiate a default ray tracer if the user
383 wants to use /vis/rayTracer commands without the benefit of the
384 vis system (scene handlers and viewers).
385
386 4th December 2005 Makoto Asai (raytracer-V07-01-08)
387 - Correct initialization of G4RTTrackingAction and G4RTSteppingAction
388
389 28th November 2005 Jane Tinslay (raytracer-V07-01-07)
390 - Remove names of unused parameters to stop compiler warnings
391
392 18th November 2005 John Allison (raytracer-V07-01-06)
393 - Merged in raytracer-V07-01-04 - see below.
394 - Implemented window positioning.
395
396 28th October 2005 Makoto Asai (raytracer-V07-01-05)
397 - Working tag for merging "envelope" into G4Region.
398 - This tag does not contain raytracer-V07-01-04 tag that might be
399 already done by J. Allison but does not yet appear on this file.
400
401 13th October September 2005 John Allison (raytracer-V07-01-04)
402 (On branch raytracer-V07-01-01-branch; changes *not* merged into head -
403 need to cvs update -j raytracer-V07-01-02 -j raytracer-V07-01-01-branch.)
404 - Migrated to <sstream>.
405 - Default background black - can be changed by /vis/viewer/set/background.
406 - GNUmakefile: Removed temporary CPPFLAGS += -DG4VIS_BUILD_RAYTRACERX_DRIVER.
407
408 30th September 2005 Joseph Perl (raytracer-V07-01-03)
409 New tag to include change Makoto made an hour after V07-01-02 was tagged.
410 Change seems to just involve passing pWorld to material list where no argument was passed in previous version.
411
412 16th September 2005 John Allison (raytracer-V07-01-02)
413 (On branch raytracer-V07-01-01-branch; changes merged into head.)
414 - Bug fix (black holes): Made small epsilon push into world to ensure inside.
415
416 20th July 2005 John Allison (raytracer-V07-01-01)
417 - Protected RayTracerX by G4VIS macro.
418
419 17th July 2005 John Allison (raytracer-V07-01-00)
420 - Introduced RayTracerX. RayTracerX opens an X window and builds up
421 the picture, refining it gradually. Already calculated pixels are
422 not recalculated, so it is as efficient as a top-to-bottom raster
423 scan. It produces a jpeg file as well, just like RayTracer.
424
425 11th June 2004 Gabriele Cosmo (raytracer-V06-01-00)
426 - Use global flag G4VIS_ALLOC_EXPORT to export extern symbols for DLLs.
427 Modified GNUmakefile and rearranged usage of extern symbols in classes.
428
429 12th November 2003 Mark Donszelmann
430 - GNUmakefile: added Modeling/include directory to compile on Windows.
431
432 6th November 2003 John Allison (raytracer-V05-02-04, vis-V05-02-03)
