144
14521st August 2007 John Allison (opengl-V09-00-00)
146- Removed redundant G4OpenGLXViewerMessenger.
147
14825th May 2007 John Allison (opengl-V08-03-03)
149- G4OpenGLSceneHandler and G4OpenGLXViewerMessenger:
150 Fixed gcc-4.1.2 compiler warnings.
151
15225th May 2007 John Allison (opengl-V08-03-02)
153- G4OpenGLXViewer: Trapped glXMakeCurrent in Initialise function.
154
15524th May 2007 John Allison (opengl-V08-03-01)
156- Fixes for SUN.
157
15816th May 2007 John Allison (opengl-V08-03-00)
159- Fix compiler warnings on SLC4.
160- Bug fixes:
161 o Correct path /vis/ogl/set/printMode.
162 o Add SetView to pixmap screen dump ("/vis/ogl/set/printMode pixmap"
163 and "/vis/ogl/printEPS").
164
1658th May 2007 John Allison (opengl-V08-02-06)
166- Moved vectored PostScript printing to G4OpenGLViewer.
167- /vis/ogl/printEPS should work for all viewers, including Win32.
168- Introduced /vis/ogl/set/printMode vectored|pixmap, currently only
169 effective on X windows (and still somewhat buggy).
170
1714th April 2007 John Allison (opengl-V08-02-05 - needs visman-V08-02-04)
172- Implemented picking for OGLSX ( as well as OGLIX). Hopefully works
173 for OGL*Win32. Still doesn't work for OGL*Xm.
174
1753rd April 2007 John Allison (opengl-V08-02-04 - needs visman-V08-02-03)
176- G4OpenGLStoredSceneHandler:
177 o Re-organised display lists on a per-primitive basis, i.e., one
178 display list per primitive. (This is so that, except for text,
179 the colour - or, rather, intensity - can be brought out of the
180 display list into the TOList (Transient Object List) and
181 controlled for the Display-by-Time feature. Previously, if more
182 than one primitive were drawn between BeginPrimitives and
183 EndPrimitives, it would finish up all in one display list, colour
184 commands included. Rationalises and fixes a rare bug in the
185 Display-by-Time feature - see August 2006.)
186 o Added AddPrimitive(const G4Polymarker&) so that it is treated as
187 one primoitive to fit with the above re-organisation.
188- Implemented picking for OGLIX.
189
19025th March 2007 John Allison (opengl-V08-02-03)
191- Fix compiler warnings.
192
1938th February 2007 John Allison (opengl-V08-02-02)
194- Fixed Windows problem with DBL_MAX. (Introduced G4OPENGL_DBL_MAX.)
195- G4OpenGLXViewer.cc: Small bug fix in print(). (Context was switched
196 .but not switched back. Not serious, because context was always set
197 before normal drawing.)
198
1999th January 2007 John Allison (opengl-V08-02-01)
200- Implemented bitmap markers for MarkerSizeType == screen. (The old
201 polygon implementation remains for MarkerSizeType == world.)
202- Added G4OpenGLBitMapStore to assist the above.
203- G4OpenGLXViewer::CreateGLXContext:
204 o Bug fix: Added missing break in colormap lookup routine.
205
2065th January 2007 John Allison (opengl-V08-02-00)
207- G4OpenGLSceneHandler.cc:
208 o Followed change of signature of GetLineWidth in visman-V08-02-00.
209 o Minor efficiency improvements.
210
21121st November 2006 John Allison (opengl-V08-01-09)
212- Fixed compiler warnings.
213
2141st November 2006 John Allison (opengl-V08-01-08)
215- Replace /vis/oglx/set/printEPS by /vis/oglx/printEPS. The new command
216 actually initiates a print, rather than set a flag for printing.
217
21824th October 2006 John Allison (opengl-V08-01-07)
219- G4OpenGLStoredViewer.cc: Calculate light front horizon properly.
220- G4OpenGLViewerMessenger.cc: Make refresh depend on auto-refresh.
221
22219th September 2006 John Allison (opengl-V08-01-06)
223- Added time origin for light front.
224- Added /vis/ogl/set/transparency.
225- G4OpenGLStoredViewer.cc: Bug fix in time range acceptance.
226
2274th September 2006 John Allison (opengl-V08-01-05)
228- Implement cutaways.
229- Immediate mode: G4OpenGLImmediateSceneHandler.cc: Flush all
230 primitives (see detector being drawn).
231- /vis/oglx/set/printEPS: change parameter default to true.
232
23330th August 2006 John Allison (opengl-V08-01-04)
234- G4OpenGLSceneHandler:
235 o Implemented line width.
236 o Switched off back face culling when clipping so that the inside of
237 volumes can be seen.
238 o Added CreateSection/CutawayPolyhedron to exploit generic
239 sectioning (DCUT) and cutaways. Currently not activated due to
240 instabilities in BooleanProcessor. Local sectioning still active
241 but broken (at least on Mac) due to apparent change in effect of
242 clipping planes (polyhedron edges not reconstructed).
243 o Rationalised calculation of marker size.
244- G4OpenGLStoredSceneHandler:
245 o Fixed bug due to recursive calls of AddPrimitive (polymarkers -> markers).
246 o Pick up time range from G4VisAttributes.
247- G4OpenGLViewer(Messenger):
248 o Added position and colour to /vis/ogl/set/displayHeadTime.
249 o Added /vis/ogl/set/displayLightFront.
250- G4OpenGLStoredViewer.cc:
251 o Rationalised CompareForKernelVisit. (Local sectioning still active.)
252 o Added position and colour to DisplayHeadTime.
253 o Added DisplayLightFront.
254
25516th August 2006 John Allison (opengl-V08-01-03)
256- Corrected Solaris compilation error.
257- Added /vis/ogl/set/fade and displayHeadTime.
258
25914th August 2006 John Allison (opengl-V08-01-02)
260- Needs visman-V08-01-02.
261- G4OpenGLStored: Implemented display-by-time. Only available in
262 stored mode at present. Only implemented for circle, square,
263 polyline and polymarker at present, enough for currently available
264 trajectory models. Time is communicated via G4AttValues.
265- Added G4OpenGLViewerMessenger.
266- Added /vis/ogl/set/startTime and endTime of displayed objects.
267- All factories: Instantiated G4OpenGLViewerMessenger.
268- G4OpenGLViewer: Added fStart/EndTime.
269- G4OpenGLXViewer.cc: Graceful recovery from unexpected tokens in
270 spewPrimitiveEPS and spewSortedFeedback.
271
27217th July John Allison (opengl-V08-01-01)
273- Added /vis/oglx/set/printEPS (prints eps file on every update).
274
2753rd July 2006 John Allison (opengl-V08-01-00)
276- Elimination of redundant variable doublebuffer and implementation of
277 FinishView in all viewers.
278
27930th May 2006 Joseph Perl (opengl-V08-00-08)
280- G4OpenGLImmediateWin32Viewer: Removed tests on doublebuffer since that
281 variable seems to have random behavior and should be assumed false for
282 this viewer.
283
28429th May 2006 Joseph Perl (opengl-V08-00-07)
285- G4OpenGLWin32Viewer, G4OpenGLImmediateWin32Viewer, G4OpenGLStoredWin32Viewer:
286 Removed common FinishView and instead made separate FinishView for the two different
287 versions of this viewer since each wants a different buffer swapping behaviour.
288
28912th May 2006 John Allison (opengl-V08-00-06)
290- G4OpenGLWin32Viewer: Fixed buffer swapping behaviour.
291
29228th April 2006 John Allison (opengl-V08-00-05 - needs visman-V08-00-14)
293- G4OpenGLStoredX/Xm/Win32Viewer.cc: Fixed buffer swapping problem when
294 recomputing transients.
295
29624th April 2006 John Allison (opengl-V08-00-04)
297- Fixed compilation problem on Windows.
298
29919th April 2006 John Allison (opengl-V08-00-03)
300- G4OpenGLSceneHandler, G4OpenGLStoredSceneHandler and
301 G4OpenGLImmediateSceneHandler:
302 o Implemented Begin/EndPrimitives2D (needs visman-V08-00-12 and
303 greps-V08-00-02).
304 o Migrated to direct access to G4PhysicalVolumeModel.
305- G4OpenGLStoredX/Xm/Win32Viewer.cc: bug fix for conditional drawing
306 of display lists in DrawView.
307
30814th March 2006 John Allison (opengl-V08-00-02)
309- Refined display list building and re-drawing algorithm.
310 o G4OpenGLStoredSceneHandler::EndModeling: Changed to GL_COMPILE_AND_EXECUTE.
311 o Avoided unnecessary re-execution in DrawView (X, Xm and Win32).
312- G4OpenGLStoredSceneHandler::RequestPrimitives: Refined display list
313 re-use algorithm. In test19 with global culling off, numbers of
314 display lists used are:
315 o 191 No re-use:
316 o 73 Before this change: re-use except replicas (includes parameterised).
317 o 33 After this change: re-use except parameterised and replicas in radius.
318
31926th January 2006 John Allison (opengl-V08-00-01)
320- Coworks with visman-V08-00-04 (removed fModified).
321- Removed references to fModified.
322- Tidying: Removed unnecessary ClearView.
323- G4OpenGLSceneHandler.cc: Added some (commented out) code for
324 possible future implementation of 2D drawing.
325- G4OpenGLXViewer.cc: Improved exception printing.
326
32711th January 2006 John Allison (opengl-V08-00-00)
328- Improved efficiency: all DrawView's:
329 o Don't call ClearView.
330 o Set flag so SetView will not be called in ProcessView.
331 o Leave background colour to ClearView.
332- Used dynamic_cast<G4OpenGLViewer*>, no need for G4OpenGLViewerDataStore.
333- G4OpenGLXmViewerMessenger: Made a smart singleton; interrogates vis manager
334 for current viewer.
335
33624th November 2005 John Allison (opengl-V07-01-09)
337- Protected G4OpenGLXmViewerMessenger with #ifdef G4VIS_BUILD_OPENGLXM_DRIVER.
338
33922nd November 2005 John Allison (opengl-V07-01-08)
340- Added G4OpenGLXmViewerMessenger.
341- Corrected text position.
342- Made depth test for polyhedron GL_LEQUAL (slightly dominant).
343
34417th November 2005 Gabriele Cosmo
345- Fixed settings of background style for WIN32 viewers.
346
34713th November 2005 John Allison (opengl-V07-01-07)
348- Implemented X-Window-style geometry hints in G4OpenGLXViewer.
349
35013th October 2005 John Allison (opengl-V07-01-06)
351- Allowed any colour background.
352- Implemented non-uniform scaling.
353- Migration to <sstream>.
354
35529th September 2005 John Allison (opengl-V07-01-05)
356- Added G4OpenGLViewerDataStore to facilitate access of viewer data by
357 scene handler.
358- Re-implemented transparency button in OpenGLXm.
359
36013th September 2005 John Allison (opengl-V07-01-04 - needs visman-V07-01-02)
361- Implemented white background for all OGL viewers.
362- G4OpenGLSceneHandler.cc:
363 o Fixed hidden line removal (bug introduced in opengl-V07-01-02).
364 o Fixed treatment of triangular polygons for drawing of auxiliary/soft lines.
365 o Corrected GetTextColour(text).
366 o Corrected GetColour(polyhedron).
367
3685th September 2005 John Allison (opengl-V07-01-03)
369- Bug fix: stored transparent objects were being lost.
370
3712nd September 2005 John Allison (opengl-V07-01-02 - needs visman-V07-01-01)
372- Bug fix: edgeflags problem introduced with smooth shading in
373 opengl-V07-01-00.
374- Implementation of a "better algorithm" for the rendering of
375 transparent polyhedron objects. It renders all opaque objects
376 first, then renders the transparent objects with the depth buffer in
377 read-only mode (see OpenGL Programming Guide). It uses the new
378 facility in G4VSceneHandler::ProcessScene for an optional second pass
379 of the run-duration models in the scene. Note this algorithm is
380 still only an approximation. It will still give the wrong blended
381 colour if two transparent objects are rendered front first. For
382 nested transparent objects, this is unfortunate, because
383 G4PhysicalVolumeModel traverses Geant4's mother-daughter hierarchy
384 in such a way that mothers come first. Also, there is no guaranteed
385 relationship between the order of rendering and the depth of two
386 transparent objects if they are at the same level or in different
387 branches of the hierarchy. Still, the only error will be an
388 incorrect colour - the objects will still give the appearance of
389 transparency, so it's a pretty good algorithm. (An even better
390 algorithm would be to attempt to render the facets in depth order,
391 deepest first. But how do you calculate the depth - centre of area,
392 deepest corner? One can still imagine pathalogical cases that would
393 sometimes give the wrong colour. Also, for stored mode, the order
394 is fixed in a display list so when the user rotates the view, one
395 would lose the depth ordering. I think we have to accept that
396 blending in OpenGL is only ever an approximation. For accurate
397 blending, use RayTracer.)
398
39928th August 2005 John Allison (opengl-V07-01-01)
400- Half-way implementation of rendering of transparent polyhedron
401 objects. In this implementation, no account is taken of the order
402 of rendering. Transparent objects are rendered with depth testing
403 off so that objects behind can still be seen. But this means that
404 opaque objects in front do not obscure them - and they jolly well
405 should! A better algorithm is to render all opaque objects first,
406 then render the transparent objects with the depth buffer in
407 read-only mode (see OpenGL Programming Guide). This is going to
408 take a little more thought - see opengl-V07-01-02.
409
41020th July 2005 John Allison (opengl-V07-01-00)
411- Introduced smooth shading, taking advantage of hitherto un-noticed
412 feature of HepPolyhedron::GetNextFacet that calculates the normals
413 at each vertex so that curved surfaces are rendered more
414 realistically (Gouraud shading).
415- G4OpenGLImmediateSceneHandler.cc: Removed unnecessary #include's.
416- G4OpenGLXmViewer.cc: Fixed to use window size hints. This changes
417 the default window size. It used to be 400x400, hardcoded in
418 G4OpenGLXmViewer.cc, but now it picks up the
419 G4ViewParameters::GetWindowSizeHintX/Y, which defaults to 600x600.
420 The user may change it on the command line, e.g:
421 /vis/open OGLSXm 500
422 or
423 /vis/viewer/create ! ! 500
424
42530th May 2005 John Allison (opengl-V07-00-03)
426- Fixed compilation problem in OpenGL on SUN. (Replaced multimap by
427 map of vectors in G4OpenGLFontBaseStore.)
428
4294th May 2005 John Allison (opengl-V07-00-02)
430- Restored sequence Set/Clear/DrawView in ClearTransientStore. (It
431 was taken out to prevent recursive calling, but that seems to be OK,
432 and it is needed to implement refresh at end of event/run.)
433
43422nd April 2005 John Allison (opengl-V07-00-01)
435- Rationalised work of opengl-V07-00-00. Functionality unchanged.
436 o G4OpenGLViewer.hh: Created virtual void CreateFontLists(){}.
437 o In all concrete viewers, added call to CreateFontLists().
438 o Moved font code for X to G4OpenGLXViewer::CreateFontLists().
439 o There is no longer a need to implement in the XmViewer, since it
440 now inherits. Thus the font code now only appears once for X.
441 o Awaiting implementation for WIN32.
442
44317th April 2005 John Allison (opengl-V07-00-00)
444- Based on vis-V07-00-13.
445- Implemented text for X-Windows viewers. Uses glXUseXFont, which
446 creates display lists for nominated fonts. Simple-minded scheme in
447 which each viewer creates its own font display lists for a variety
448 of sizes, which are accessed by the scene handler through a new
449 class, G4OpenGLFontBaseStore. Affected methods:
450 G4OpenGLXViewer::CreateMainWindow()
451 G4OpenGLXmViewer::CreateMainWindow()
452 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text)
453
45418th November 2004 John Allison (opengl-V06-02-07)
455- Removed redundant fLastVP from G4OpenGLStoredSceneHandler.
456
45715th November 2004 Guy Barrand
458- G4OpenGLWin32Viewer::ShowView : glFlush was not sufficient
459 to see trajectories (for example with N03). Correct so that
460 ShowView do a FinishView that does : glFlush, wglSwapBuffer

501
5027th April 2004 Guy Barrand
503- visualization/OpenGL/* : use the G4OpenGL.hh file.
504- Added : visualization/OpenGL/include/G4OpenGL.hh to encapsulate
505 the include of gl/gl.h and gl/glu.h that may be platform dependant.
506 It permits to rm some #ifdef WIN32 spread in the code. It opens also
507 the way to the usage of the Apple OpenGL on a Mac.
508

56324th August 2001 John Allison (vis-V03-02-13)
564- Limited the printing of warnings in
565 G4OpenGLSceneHandler::AddPrimitive (const G4Text& text).
566
56714th August 2001 John Allison (vis-V03-02-11)
568- Improved KernelVisitDecision.
569- Fixed a few small bugs in multiple "stored" viewers, but see next item.
570- There's an outstanding bug in OpenGL Stored. If there is more than
571 one viewer controlled by a scene handler, after a ClearStore on the
572 scene handler, e.g., with /vis/scene/notifyHandlers, the first
573 viewer to get refreshed should trigger the display list rebuild, but
574 the second need not. However, when the second viewer's turn comes,
575 the display lists are there, and are called, e.g.,
576 G4OpenGLStoredXViewer::DrawView calls
577 G4OpenGLStoredViewer::DrawDisplayLists that calls glCallList, but
578 nothing appears on the screen. To overcome this there is some
579 temporary code in G4VViewer::NeedKernelVisit which marks *all*
580 viewers to force a rebuild. To see the symptoms, comment out that
581 temporary code and issue these commands:
582 /vis/verbose c
583 /control/verbose 2
584 /vis/scene/create
585 /vis/scene/add/volume
586 /vis/sceneHandler/create OGLSX
587 /vis/viewer/create ! ! 1
588 /run/beamOn
589 /vis/viewer/create ! ! 1
590 /vis/viewer/select viewer-0
591 /vis/viewer/viewpointThetaPhi 20 20
592 /vis/viewer/select viewer-1
593 /vis/viewer/viewpointThetaPhi 40 40
594 /vis/viewer/set/style surface
595 /vis/viewer/refresh
596 /vis/viewer/select viewer-0
597 /vis/viewer/refresh
598 /vis/viewer/select viewer-1
599 /vis/viewer/set/style wireframe
600 /vis/scene/notifyHandlers
601 You may have to do this too:
602 /vis/viewer/select viewer-0
603 /vis/scene/notifyHandlers
604 One of the viewers is empty. Curious!!
605
6069th August 2001 John Allison (vis-V03-02-10-00)
607- Implemented G4OpenGLStoredSceneHandler::ClearTransientStore()
608- Removed G4OpenGLSceneHandler::AddPrimitive (const G4Polymarker&) (it only
609 invoked G4VSceneHandler::AddPrimitive (const G4Polymarker&) which is
610 picked up by inheritance anyway.
611- Removed lots of unnecessary header files from G4OpenGLStoredSceneHandler.cc.
612- Corrected order of calling base class functions in
613 G4OpenGLStoredSceneHandler::Begin/EndModeling.
614
61524th July 2001 John Allison (vis-V03-02-06)
616- G4OpenGLSceneHandler::AddPrimitive (const G4Text&) handles transformation.
617
61814th July 2001 John Allison (opengl-V03-02-00)
619- Fixed crash in optimised mode: added Initialise() to viewers so
620 that windows are opened after viewers are fully constructed.
621
6222nd April 2001 John Allison (opengl-V03-00-01 wrt vis-V03-00-09)
623- Tidied G4OpenGLXmViewer callback code. Removed superfluous header files.
624
6257th March 2001 John Allison
626- Changed char* to const char* in many places and that gave problems in
627 calls to Xt and Xm. Hope all's OK. Differences:
628 cvs diff -r vis-V03-00-06 vis-V03-00-07
629
63025th January 2001 John Allison (opengl-V03-00-00)
631- Implemented running re-calculation of up-vector in the case of "object
632 rotation" (lights move with camera) to prevent "flipping" of view when
633 camera passes through up-vector. Note that the default is "camera
634 rotation" (lights do not move with camera, i.e., remain fixed relative
635 to object) so the default is that this "flipping" can happen. To set
636 "object rotation" (lights move with camera) use
637 /vis/lights/move_with_camera true (soon to be
638 /vis/viewer/set/lights move-with-camera) or click "Object" radio button
639 on Rotation Panel in OpenGLXm mode.
640- Changed some objects to references for efficiency. E.g.:
641 const G4Vector3D& vp = pView->fVP.GetViewpointDirection ().unit ();
642
64322nd May 2000 John Allison (opengl-V01-01-00)
644- Fixed slow response of 2nd window of OpenGLXm. Worked around Mesa bug
645 by sharing static visuals in G4OpenGLXViewer (Guy Barrand):
646 static XVisualInfo* vi_single_buffer;
647 static XVisualInfo* vi_double_buffer;
648- Removed ChooseVisual from G4OpenGLXmViewer.cc - done in base class
649 G4OpenGLXViewer.
650- Protected double deletion of window in destructors of G4OpenGLXmViewer
651 and G4OpenGLXViewer (Guy Barrand).
652- Changed requested bits per colour to r,g,b = 1,1,1 in G4OpenGLViewer.cc.
653- Corrected order of CreateMainWindow() and InitializeGLView() in X*Viewer
654 constructors.
