by obsolete GNUmake system

- G4OpenGLStoredXmViewer destructor:
|
||||
No need to RemoveViewerFromList - this is done in the G4VViewer base class.

- G4OpenGLImmediateSceneHandler.hh: idem as below.
|

- G4OpenGLStoredSceneHandler.hh: idem as below.
|

- G4OpenGLSceneHandler.hh: to quiet g++ about "AddPrimitive(G4Plotter&)", have:
|

using G4VSceneHandler::AddPrimitive;

21 September 2021 Guilherme Amadio (opengl-V10-07-21)
|
||||
- G4OpenGLViewer:
|
||||
o Fix C++20 warnings from GCC 11.2.0.
|
||||
|
||||
06 September 2021 John Allison (opengl-V10-07-20)
|
||||
- G4OpenGLImmediateQtViewer.cc and G4OpenGLStoredQtViewer.cc:
|
||||
o Set jpg as default export format for Qt viewers.
|
||||
. For use with /vis/ogl/export.
|
||||
. jpg is only available for Qt viewers - pdf is the default for
|
||||
other OpenGL viewers.
|
||||
. jpg is more faithful than pdf. For example, pdf, which uses gl2ps,
|
||||
is not good with transparency. Also gl2ps does not do text.
|
||||
. For complicated images - detectors of many tracks - gl2ps creates
|
||||
*huge* files. I have seen some 1000x bigger than the equivalent jpg.

|
||||
- G4OpenGLQtViewer::DrawText:
|
||||
o Fix text alignment issue with a fudge factor.
|
||||
o Specialise fudge factor for __APPLE__. It seems only Mac has this
|
||||
problem. Maybe it's to do with the retina display. Maybe Qt keeps
|
||||
it's own pixel size.
|
||||
|
||||
20 July 2021 John Allison (opengl-V10-07-18)
|
||||
- G4OpenGLViewerMessenger:
|
||||
o Remove /vis/ogl/printEPS.
|
||||
o This command is covered by the more versatile /vis/ogl/export.
|
||||
|
||||
19 July 2021 John Allison (opengl-V10-07-17)
|
||||
- G4OpenGLSceneHandler.cc:
|
||||
o Use C++17 [[fallthrough]] instead of // fallthrough in switch statements.
|
||||
|
||||
17 July 2021 John Allison (opengl-V10-07-16)
|
||||
- Rationalise image exporting in preparation for removing /vis/ogl/printEPS.
|
||||
o G4OpenGLViewer:
|
||||
. Subsume the code in printEPS into exportImage, thereby allowing
|
||||
the removal of the former function. exportImage is the "primary"
|
||||
function, called by the printEPS and export commands and callback
|
||||
functions. It calls printEPS, and is the only function to do so, so
|
||||
to rationalise and avoid confusion, move all the code to exportImage.
|
||||
o G4OpenGLXmViewer::print_callback:
|
||||
. Call exportImage instead of printEPS.
|
||||
|
||||
13 July 2021 John Allison (opengl-V10-07-15)
|
||||
- G4OpenGLStoredSceneHandler.cc, G4OpenGLViewerMessenger.cc:
|
||||
o Increase the default display list limit to 10 million.
|
||||
o The default OpenGL display list limit was 50,000, an archaic value
|
||||
from the days when memory was much more limited than is typical today.
|
||||
This MR increases the default value to 10 million, easily accommodated
|
||||
by modern RAM and GPU memory.
|
||||
o The number can be changed with /vis/ogl/displayListLimit, either to
|
||||
increase it further or lower it, subject to a lower limit of 10,000.
|
||||

- G4OpenGLImmediateXViewer::FinishView()
|
||||
- G4OpenGLImmediateXmViewer::FinishView()
|
||||
- G4OpenGLStoredXViewer::FinishView()
|
||||
- G4OpenGLStoredXmViewer::FinishView()
|
||||
- G4OpenGLXViewer::ShowView()
|
||||
- G4OpenGLXmViewer::ShowView()
|
||||
o Comment out glXWaitGL().
|
||||
. Wait for effects of all previous OpenGL commands to be propagated
|
||||
before progressing.
|
||||
. Commented out July 2021 - slows rendering down in some cases and I
|
||||
don't see any adverse effects.

||||

08 July 2021 John Allison (opengl-V10-07-13)
|
||||
- G4OpenGLSceneHandler.cc:
|
||||
o Disable (comment out) backface culling.
|
||||
- G4OpenGLStoredViewer.cc and G4OpenGLStoredQtViewer.cc:
|
||||
o Suppress kernel visit (no longer needed) for cutaway drawing.
|
||||
- Note 1: Section and Cutaway can reveal back-facing faces. If backface culling
|
||||
is implemented, the image can look strange because the back-facing faces are
|
||||
not there. As described above, we have disabled (commented out) backface
|
||||
culling. It seems not to affect performance - in fact, performance seems to
|
||||
improve it. Maybe the feature is archaic and modern GPUs are simply more
|
||||
efficient if backface culling is not requested.
|
||||
- Note 2: In G4OpenGLStored(Qt)Viewer::CompareForKernelVisit we decide if a
|
||||
"kernel visit" (which involves a reconstruction of the graphical database
|
||||
from the Geant4 kernel) is required on a change of view parameters. Simple
|
||||
rotating and zooming does not require a kernel visit, but more sophisticated
|
||||
parameters may. In G4OpenGLSceneHandler we implement cutaways using
|
||||
OpenGL cut planes, so now we have disabled backface culling, we do NOT need
|
||||
to visit the kernel. This is the change that makes a huge speed up when
|
||||
a user requests cutaways.

05 July 2021 John Allison (opengl-V10-07-12)
|
||||
- G4OpenGLQtViewer:
|
||||
o Use modelShortName instead of modelDescription for TreeWidgetItem
|
||||
for nonPVmodel.
|
||||
|
||||
30 June 2021 John Allison (opengl-V10-07-11)
|
||||
- Requires greps-V10-07-09, modeling-V10-07-11 and visman-V10-07-11.
|
||||
- Revise vis models. See visualization/modeling/History for more details.
|
||||
- Consequent changes:
|
||||
o AddPrimitive(const G4Scale&) has been removed from all scene handlers.
|
||||
|
||||
29 June 2021 Gabriele Cosmo (opengl-V10-07-10)
|
||||
- Fixed compilation error in G4OpenGLXmConvenienceRoutines when c++20 is enabled.
|
||||
|
||||
07 June 2021 John Allison (opengl-V10-07-09)
|
||||
- Requires greps-V10-07-07 (new method AddCompound (const G4Mesh&)).
|
||||
- Requires modeling-V10-07-09 (new class G4Mesh).
