|
|
List of features and fixes included in this Beta release since 11.3.p02:
|
|
|
|
o Configuration:
|
|
-------------
|
|
+ CMake:
|
|
o Set default configuration to use Qt6 when selecting Qt support.
|
|
User must set GEANT4_USE_QT_QT5 to force find/use of Qt5.
|
|
o Include external categories (G4zlib etc) in link resolution for unit
|
|
test executables.
|
|
o Export CMAKE_EXPORT_COMPILE_COMMANDS setting from toolkit to the build
|
|
of any test done by geant4_add_test to assist use of clang-tidy and
|
|
other tooling.
|
|
o Add ENVIRONMENT to any build step of geant4_add_test for consistency
|
|
and to allow easier propagation of additional build settings.
|
|
o Updated to datasets: G4EMLOW-8.7.
|
|
+ GNUmake:
|
|
o Updated system scripts for Qt settings: set Qt6 as default.
|
|
o Correction in generation of geant.[c]sh and geant4.bat on Windows.
|
|
|
|
o Analysis:
|
|
--------
|
|
+ New implementation of generic 'G4Analysis::GetHnType()' and 'IsProfile()'
|
|
functions, which do not rely on the histogram/profile name position in
|
|
the long type name provided via tools 's_class()'.
|
|
+ Modernized g4tools macro-based for loops with range-based for.
|
|
|
|
o Externals:
|
|
---------
|
|
+ g4tools:
|
|
o Updated to version 6.5.1.
|
|
o Implemented windows_size and render_area_size methods; fixed setting of
|
|
mouse position in the wheel_rotation_event. Handle the shift and control
|
|
modifiers in the mouse_[down,up,move]_event and wheel_rotation_event.
|
|
o In glarea, in mouseMoveEvent() for Qt5, corrected a bad cut/paste when
|
|
creating the mouse_move_event.
|
|
o In *ntuple, fix in the initialise() method, to switch from "warning" to
|
|
"error" and return false if the name of a booking column is not found
|
|
in the file. Addressing problem report #2657.
|
|
+ zlib:
|
|
o Updated zlib to version 1.3.1. Prior Geant4 patches are retained.
|
|
|
|
o Geometry:
|
|

|
|
o Updated implementation of QSS integration method to QSS version-2.
|
|
+ management:
|
|
o Enabled voxelisation parallelism by default in G4GeometryManager, when
|
|
MT/tasks are enabled. Enabled also for potential 2nd (and later) calls
|
|
in runs after geometry was changed.
|
|
o G4VSolid: set seed in EvaluateCubicVolume() and EvaluateSurfaceArea()
|
|
to ensure reproducibility of the resulting value.
|
|
o G4GeomTools: added functions HyperboloidSurfaceArea(), HypeStereo()
|
|
and TwistedTubeBoundingTrap().
|
|
o Applied clang-tidy fixes fixes (readability, modernization,
|
|
performance, ...) based on llvm version 19.1.17.
|
|
+ navigation:
|
|
o Extended UI command "/geometry/test/run" to support optional overlap
|
|
check mode: depending on the selected mode, it invokes either
|
|
'TestRecursiveOverlap' (default and original algorithm) or
|
|
'TestOverlapInTree', allowing to check for overlaps in the volume tree
|
|
without duplication in identical logical volumes.
|
|
o Reorganised and enriched comments in headers to follow Doxygen style.
|
|
o Removed declared but not implemented methods in G4VoxelNavigation,
|
|
G4ParameterisedNavigation, G4VoxelSafety and G4PathFinder.
|
|
+ solids/Boolean:
|
|
o G4MultiUnion: fix in GetSurfaceArea() and some optimisation to use
|
|
G4QuickRand(). In GetLocalPoint(), GetLocalVector(), GetGlobalPoint()
|
|
and GetGlobalVector(), make direct usage of the transformation matrix
|
|
elements.
|
|
+ solids/CSG:
|
|
o G4Box: code restructuring in DistanceToOut() methods.
|
|
o G4Orb: provide faster algorithm in GetPointOnSurface().
|
|
o G4Para: speedup calculation of surface area in GetSurfaceArea() and
|
|
GetPointOnSurface().
|
|
o G4Box, G4Para, G4Trd: code optimization in GetPointOnSurface().
|
|
o G4Torus: implemented uniform sampling of random points on surface.
|
|
+ solids/specific:
|
|
o G4Ellipsoid, G4EllipticalTube: code optimization in GetPointOnSurface().
|
|
o G4TessellatedSolid, G4TriangularFacet, G4QuadrangularFacet: use
|
|
G4QuickRand() for generating points on surface.
|
|
o G4EllipticalCone: code optimization in GetPointOnSurface(); moved
|
|
setters implementations to source.
|
|
o G4Paraboloid: implemented uniform sampling of random points on surface.
|
|
o G4Hype: revised surface area calculation and random point sampling.
|
|
Code optimization in GetPointOnSurface().
|
|
o Use G4QuickRand() in G4PolyPhiFace, G4PolyconeSide, G4PolyhedraSide,
|
|
G4TwistedTubs, G4VCSGfaceted and G4VTwistedFaceted for sampling points
|
|
on surface.
|
|
o G4EllipticalCone, G4EllipticalTube, G4Voxelizer: removed unnecessary
|
|
headers.
|
|
+ volumes:
|
|
o Fix to only delete the logical skin/border surfaces if the geometry
|
|
is not closed.
|
|
o Reorganised and enriched comments in headers to follow Doxygen style.
|
|
o Applied clang-tidy fixes for readability, based on llvm version 19.1.7.
|
|
|
|
o Global:
|
|
------
|
|
+ Factored common ieee754 union and helper functions out of G4Log and
|
|
G4Exp to remove code duplication.
|
|
+ G4VSIntegration: added new utility class for integration of probability
|
|
density function and dynamically sampling of final state. This is useful
|
|
for the case when sampling tables cannot be prepared and stored, instead
|
|
computations are performed for each case again and again.
|
|
+ G4QuickRand: Added a possibility to set a seed.
|
|
+ Changed date for release 11.4-beta.
|
|
|
|
o Graphics Representations:
|
|
------------------------
|
|
+ Re-instated transparency slider in GUI.
|
|
+ G4VGraphicsScene: added 'fMaxGeometryDepth' data member and
|
|
corresponding access functions.
|
|
|
|
o Intercoms:
|
|
---------
|
|
+ In G4UImanager and G4UIcontrolMessenger, introducing "@@" keyword that
|
|
can be placed in any UI command taking a macro file name. It creates a
|
|
temporary macro file with defined commands until the "/control/endRecord"
|
|
command is specified. The "@@" mechanism works recursively.
|
|
If a file name is enclosed in a pair of "@", that macro file is created.
|
|
The mechanism works for both interactive mode and batch mode. When used
|
|
in interactive mode with Qt GUI, one can use up-arrow, tab-key and
|
|
clickable menu in left-side bar to complete a command.
|
|
|
|
o Interfaces:
|
|
----------
|
|
+ G4UIQt: re-instated transparency slider.
|
|
Introduced Time Window tab. This exploits generic time windowing
|
|
recently introduced in visualisation. Currently, it doesn't work with
|
|
OGL in Qt6. The TSG visualisation driver works fine with both Qt5 and
|
|
Qt6, except line width is not implemented.
|
|
Simplified and improved touchable dump, using QScrollArea instead of
|
|
QMessage. Improved pick info window size.
|
|
+ General code tidy.
|
|
|
|
o Persistency:
|
|
-----------
|
|
+ gdml:
|
|
o Fix to pre-pend '0x' string before the address when writing entities
|
|
on Windows platform. Addressing problem report #2322.
|
|
|
|
o Physics Lists:
|
|
-------------
|
|
+ Builders:
|
|
o In G4HadronPHPBuilder, G4ParticleHPCapture and G4ParticleHPCaptureData
|
|
are replaced by G4NeutronRadCaptureHP and G4NeutronHPCaptureData,
|
|
respectively.
|
|
The first allows the use of the full list of updated PhotonEvaporation
|
|
data set, while for the second it is only a change of the name, the
|
|
data are the same. Addressing problem report #2660.
|
|
+ Constructors:
|
|
o electromagnetic:
|
|
- G4GeneralGammaProcess: updated destructor according to modification
|
|
in electromagnetic/utils.
|
|
- G4EmDNABuilder: use G4DNABornIonisationModel1 for proton ionisation.
|
|
For Opt8 configuration, use the same configuration of models for e-
|
|
and protons as in Opt2.
|
|
- In all DNA constructors the upper limit for DNA models for ions is
|
|
set to 300 MeV instead of 400 MeV; for increase/decrease processes
|
|
it is set to 100 MeV; for ionisation of hydrogen it is set to 100 MeV.
|
|
- G4EmDNAPhysics_option6: disabled "fast" flag in order to have
|
|
comparisons with Opt4 in the same set of general DNA parameters.
|
|
- G4EmDNAPhysics_stationary_X constructors: added deprecation warning,
|
|
indicating that these constructors are now obsolete.
|
|
- G4EmDNABuilder, G4EmDNAPhysicsActivator: introduced usage of the
|
|
new ion ionisation model in DNA Opt8 physics configuration.
|
|
- G4EmDNAPhysics, G4EmDNAPhysics_option2, G4EmDNAPhysics_option4,
|
|
G4EmDNAPhysics_option6, G4EmDNAPhysics_option8: updated interface to
|
|
G4EmDNABuilder.
|
|
o gamma_lepto_nuclear:
|
|
- G4EmExtraPhysics: removed LEND photo-nuclear; it is now selected by
|
|
G4HadronPhysicsLEND.
|
|
o hadron_elastic:
|
|
- In G4ChargeExchangePhysics, fixed usage of the messenger.
|
|
o hadron_inelastic:
|
|
- In G4HadrocPhysicsQBBC, disabled General Neutron Process.
|
|
Addressing problem reports #2558 and #2559.
|
|
- Added G4HadronPhysicsLEND to define neutron and photon induced
|
|
processes from LEND.
|
|
- G4HadronPhysicsShielding: removed LEND neutron process, now selected
|
|
by G4HadronPhysicsLEND.
|
|
+ Lists:
|
|
o G4PhysListFactory: prevent fallback to default physics list when an
|
|
invalid name is provided. Now, if a user specifies an unknown physics
|
|
list, Geant4 will throw a fatal error instead of silently using
|
|
FTFP_BERT. This ensures that users are aware of incorrect configurations
|
|
and helps preventing unintended simulation results.
|
|
o In QBBC physics list, added G4ChargeExchangePhysics.
|
|
o In Shielding physics list, simplified logic tree for inelastic models
|
|
and moved all LEND hadronic inelastic processes to G4HadronPhysicsLEND.
|
|
|
|
o Electromagnetic Processes:
|
|
-------------------------
|
|
+ DNA:
|
|
o Added new G4DNARuddIonisationDynamicModel, which uses charge from
|
|
G4DynamicParticle. The model is applicable for all ions.
|
|
o G4DNABornIonisationModel: new implementation of the Born model using
|
|
G4DNASamplingTable class; use stationary and fast flags from EM
|
|
parameters.
|
|

|
|
G4DNABornIonisationModel2: fixed definition of the stationary code via
|
|
G4EmParameters.
|
|
o G4DNASamplingTable, new class allowing the sharing of sampling data
|
|
between threads.
|
|
o Updated IRT-syn model for high LET applications.
|
|
o Correction in the G4DNAScavengerProcess for IRT-syn model.
|
|
o Created G4ChemReboundTransportation to handle the rebound transportation
|
|
of the molecule.
|
|

|
|
for managing counters.
|
|
o Replaced shared_ptr with unique_ptr and raw for manager counters.
|
|
o Fixed FPE on G4ChemReboundTransportation::calculateNextCoordinate().
|
|
o In G4PhysChemIO, removed dependency on 'analysis' module.
|
|
+ Low Energy:
|
|
o G4LivermorePhotoElectricModel: reorganisation of initialisation and
|
|
data destruction.
|
|
o In G4AtomicTransitionManager, G4UAtomicDeexcitation, use std::size_t
|
|
and few other cosmetic changes.
|
|
o In G4hIonEffChargeSquare, fixed reported Coverity defect.
|
|
+ Muons:
|
|
o G4RiGeMuPairProductionModel, G4RiGeAngularGenerator: fixes to the
|
|
angular distribution of electrons and positrons.
|
|
o G4MuPairProduction: enable RiGe model via G4EmParameters.
|
|
+ Pii:
|
|
o Use "const G4String&" in G4hImpactIonisation::InitializeMe() to avoid
|
|
unnecessary copy, reported by Coverity.
|
|
+ Standard:
|
|
o Added G4LowPAIH2O model for dE/dx in water for p and e-.
|
|
o G4UrbanMscModel: cosmetic change for Opt3 case; minor code improvement
|
|
and updated comments to the code. Not affecting any result.
|
|
o Reverted changes introduced in release 11.3 for static data
|
|
initialization in G4eBremsstrahlungRelModel.
|
|
+ Utils:
|
|
o New base class G4VXRayModel for X-ray processes. Adapted classes
|
|
G4OpticalParameters, G4OpticalParametersMessenger and G4LossTableManager
|
|
to configure and use G4VXRayModel.
|
|
o G4EmParametersMessenger: added UI command to enable/disable 5D pair
|
|
production model by muons.
|
|
o G4EmUtility, G4EmDataHandler, G4EmDataRegistry: removed minor memory
|
|
leaks and improved destruction at exit.
|
|
o G4EmParameters, G4EmParametersMessenger, G4EmUtility, G4LossTableBuilder,
|
|
G4VEnergyLossProcess: implemented new option to enable/disable
|
|
fluctuation of energy loss per G4Region.
|
|
o G4VEmProcess: added call to StartTracking(..) for all used models,
|
|
which need access to G4Track pointer.
|
|
+ Xrays:
|
|
o In G4Scintillation, build the scintillation integral tables for
|
|
materials that have non-empty material property tables and added
|
|
method BuildInverseCdfTable().
|
|
o In G4Cerenkov, build the Cerenkov integral only for materials that
|
|
have non-empty material property tables.
|
|
|
|
o Hadronic Processes:
|
|
------------------
|
|
+ cross_sections
|
|
o G4NeutronInelasticXS, G4ParticleInelasticXS: added download data for
|
|
all elements in class constructor, avoiding lazy initialisation at
|
|
run-time. No locks are set any longer by these cross-section classes.
|
|
For simple applications, the initialisation CPU time increases by
|
|
roughly 10%; no effect on complex applications.
|
|
o G4ChargeExchangeXS: fixed selection of reaction for compound materials;
|
|
added extra public and private methods; added extra method for sampling
|
|
of scattering angle; updated parameterisation using new fit to data.
|
|
o Fixed minor memory leaks in classes G4CrossSectionFactory,
|
|
G4CrossSectionFactoryRegistry, G4CrossSectionFactory,
|
|
G4ElectroNuclearCrossSection and G4ChipsAntiBaryonElasticXS.
|
|
o G4EMDissociationCrossSection: fixed several technical inaccuracies
|
|
in the code, addressing reported Coverity defects and to correctly
|
|
use G4Pow.
|
|
o G4ParticleInelasticXS: fixed reported Coverity defect.
|
|
o In G4EMDissociationSpectrum, added protection against beta=0, to fix
|
|
reported Coverity defect; correctly use G4Pow.
|
|
+ management
|
|
o G4HadronicProcess: removed warning for the case when K0 and anti-K0
|
|
are transformed into K0S or K0L.
|
|
+ models/coherent_elastic
|
|
o G4ChargeExchange: fixed problem in kinematic computations, allowed
|
|
recoil nucleus to be in an excited state. Fixed issue in final state
|
|
generation for the case of unstable meson production omega(782) and
|
|
f2(1270).
|
|
o G4ChargeExchange, G4HadronElastic: cleanup final state generation; use
|
|
the numerical limit for argument of the exponent to avoid precision
|
|
loss; in case of numerical problems force scattering angle to zero (do
|
|
not consider scattering backwards); use similar parameterisation and
|
|
code for both models. Fixed reported Coverity defect.
|
|
+ models/de_excitation
|
|
o Added G4FermiBreakUpAN, new alternative FermiBreakUp model and support
|
|
classes, contributed by A. Novikov (Yandex and MIPT) through
|
|
[GitHub PR #84](https://github.com/Geant4/geant4/pull/84). The model is
|
|
based on: J.P. Bondorf et al., Physics Reports, 257(3):133-221.
|
|
o G4ExcitationHandler, G4DeexPrecoParameters: updated initialisation
|
|
to allow switching between different FermiBreakUp models.
|
|
o G4DeexPrecoUtility: new class, providing common computation, to avoid
|
|
code duplication. Use it in classes G4EvaporationProbability,
|
|
G4ProtonEvaporationProbability, G4DeuteronEvaporationProbability,
|
|
G4TritonEvaporationProbability, G4He3EvaporationProbability and
|
|
G4AlphaEvaporationProbability, simplifying code.
|
|
o G4DeexPrecoParameters: added extra enumerator to choose variants of
|
|
the pre-compound model.
|
|
o G4NucLevel, G4PhotonEvaporation: use explicit type conversion from
|
|
double to float; use const arguments where possible.
|
|
o G4VEmissionProbability, G4EvaporationProbability, G4GEMProbabilityVI:
|
|
updated algorithms of integration of probabilities and sampling of
|
|
kinetic energy for emitted fragment. Expected more accurate spectra.
|
|
o G4GEMChannelVI, G4EvaporationGEMFactoryVI, G4DeexPrecoParameters: new
|
|
GEM de-excitation model with 83 decay channels.
|
|
o G4VEmissionProbability: use the new utility class G4VSIntegration,
|
|
to simplify code; not affecting results.
|
|
Updated parameters of integration of the probability density function.
|
|
o In G4PhotonEvaporation, G4VEmissionProbability, check life time of
|
|
final excitation level; special treatment for the ground state and the
|
|
next level. Addressing problem report #2660.
|
|
o In G4EvaporationProbability, fixed computation of inverse cross-section.
|
|
o G4StatMFMicroPartition: code cleanup, removed non-informative printout,
|
|
which can be repeated many times; instead stop MF model and return to
|
|
de-excitation handler.
|
|
o G4LevelReader: fix for reported Coverity defect.
|
|
o G4VFermiFragmentAN, G4FermiBreakUpAN: fixed reported Coverity defects.
|
|
o G4CoulombBarrier: some code cleanup.

|
+ models/em_dissociation
|
|
o G4EMDissociation: fixed reported Coverity defects.
|
|
+ models/inclxx
|
|
o Fixed one more reported Coverity defect for use of std::move()
|
|
in G4INCLCascade.
|
|
o Fixed URL to Root in comments.
|
|
Fixes [GitHub PR#87](https://github.com/Geant4/geant4/pull/87).
|
|
+ models/lend
|
|
o Major update of GIDIplus interface with refactored C++ code, including
|
|
use of official GNDS formatted data.
|
|
o Added feature for high-fidelity gamma cascades following reactions such
|
|
as neutron capture and inelastic scattering.
|
|
o Collect all inelastic models (neutron and gamma induced) into
|
|
G4HadronPhysicsLEND. Updated and simplified Shielding and
|
|
G4EmExtraPhysics accordingly.
|
|
o Fix in G4EmExtraPhysics for failing in loading photonuclear from LEND
|
|
if G4GammaGeneralProcess existed.
|
|
o Fix in G4LENDCombinedModel photofission; check energy function was not
|
|
connected to the base class, resulting in a crash.
|
|
+ models/nudex
|
|
o Address maybe-unitialized warnings when building/linking with LTO,
|
|
identified by ATLAS.
|
|
+ models/particle_hp
|
|
o G4ParticleHPThermalScatteringData: attempt to fix reported Coverity
|
|
defect on wrong handling of map iterator. Substituted several calls to
|
|
G4HadronicExceptions by one G4Exception inside BuildPhysicsTable(..)
|
|
method, which provides a fatal exception if a particle is not a neutron.
|
|
Simplified IsApplicable(..) methods called at each step; the directory
|
|
path is taken from G4ParticleHPManager to reduce number of calls to
|
|
getenv() function; initialisation is performed only once in one
|
|
instance of the class; initilised data structures are saved to
|
|
G4ParticleHPManager and are accessed from all threads and instances;
|
|
end of job destruction is also performed only once; removed commented
|
|
lines and extended comments to code.
|
|
o In G4ParticleHPInelastic, fixed AllHP physics for initialisation of
|
|
neutrons and light ions. Addressing problem report #2591.
|
|
o G4ParticleHPThermalScattering, G4ParticleHPThermalScatteringData,
|
|
G4ParticleHPJENDLHEData: fixed reported Coverity defects for
|
|
unprotected access to maps.
|
|
o Fixed reported Coverity defects, mainly in handling of maps and finding
|
|
of isotopes.
|
|
+ models/pre_equilibrium
|
|
o New classes G4PreCompoundInterface, G4PreCompoundTransitionInt and
|
|
G4PreCompoundEmissionInt with alternative precompound model.
|
|
o G4PreCompoundModel, G4PreCompoundTransition, G4PreCompoundEmission:
|
|
added an option to use alternative precompound models, which may be
|
|
done via configuration without change of interface to consumer code;
|
|
introduced verbose flag and extended printout needed to debug; removed
|
|
old commented printout lines.
|
|
o G4PreCompoundFragment, G4PreCompoundNucleon, G4PreCompoundIon: updated
|
|
computation of inverse cross-section; added factor to cross-section.
|
|
o G4VPreCompoundFragment, G4PreCompoundFragment, G4HETCFragment: use the
|
|
new utility class G4VSIntegration, to simplify code; not affecting
|
|
results.
|
|
o G4PreCompoundFragment, G4PreCompoundProton, G4PreCompoundDeuteron,
|
|
G4PreCompoundTriton, G4PreCompoundHe3, G4PreCompoundAlpha: use new
|
|
utility class G4DeexPrecoUtility.
|
|
+ util
|
|
o G4HadronicParameters: implemented pretty-print to ostream to allow
|
|
users to check values at runtime, a-la G4EmParameters (request from
|
|
ATLAS).
|
|
|
|
o Run:
|
|
---
|
|
+ Fix in G4RunManager::ReinitializeGeometry(); the logical skin/border
|
|
surfaces (used for optical physics) contain pointers to logical/physical
|
|
volumes that are deleted when the geometry is reset. Resetting the
|
|
geometry will also clear these surface tables.
|
|
|
|
o Track & Tracking:
|
|
----------------
|
|
+ G4VTrajectory and G4VTrajectoryPoint: added caching of G4AttValues.
|
|
GetAttValues() returns a shared_ptr that points to the object created by
|
|
CreateAttValues() if not already created. Thus acts as a cache.
|
|
Protected copy and move constructors and copy and move assignment
|
|
operators.
|
|
+ G4RichTrajectoryPoint: added accessors for Pre/PostStepPointGlobalTime.
|
|
This allows fast access for time windowing feature of trajectory modeling.
|
|
|
|
o Visualization:
|
|
-------------
|
|
+ management:
|
|
o Make the TSG driver the "flagship" visualization driver.
|
|
In G4VisExecutive, make nickname/alias OGL synonymous with TSG and make
|
|
TSG the default for selection by build flags.
|
|
o Re-instated the transparency slider; re-implemented it in a generic way,
|
|
i.e., for all drivers; uses a new UI command:
|
|
"/vis/viewer/set/transparencyByDepth <d> [option]".
|
|
G4UIQt issues this command on signals from the slider. The user may,
|
|
of course, use this command directly.
|
|
o Split scene processing into its "permanent" (run-duration models) and
|
|
"transient" (end-of-event and end-of-run models) parts.
|
|
This allows to update just the transient part, e.g., trajectories,
|
|
which we might want to display in a different way, leaving the
|
|
permanent part (e.g., detector) unchanged, avoiding unnecessary
|
|
re-processing. This is exactly the situation for time windowing - the
|
|
detector does not change, the trajectories also actually do not change,
|
|
just the way they are drawn changes.
|
|
o G4VSceneHandler: introduced ProcessTransients() virtual function.
|
|
Moved pertinent code from ProcessScene() to ProcessTransients().
|
|
Copied time parameters into modeling parameters.
|
|
Calculate and maintain 'fMaxGeometryDepth', new base class data member.
|
|
Improved some diagnostic printing.
|
|
o G4VViewer: introduced ProcessTransients() method. Follow changes in
|
|
G4PhysicalVolumeModel.
|
|
Initialise fTransientsNeedRedrawing to "false". Previously, this was
|
|
initialised "true", but it is up to the viewer to decide if transients
|
|
(trajectories) need redrawing. Code tidy.
|
|
o Added RayTracerQt in G4VisExecutive.
|
|
o G4VVisCommand: in InterpolateViews(), implemented desired time per time
|
|
step. Computation time per step may cause this to increase.
|
|
o G4VisCommandsViewer: improved guidance of "/vis/viewer/interpolate"
|
|
command. In "/vis/viewer/set/timeWindow/displayHeadTime", implemented
|
|
"current as default". There might be some minor change of behaviour.
|
|
In "/vis/viewer/select", removed subsequent refresh, even for
|
|
auto-refresh drivers. Refresh is not required after a select, window
|
|
systems keep the image.
|
|
o In G4VisCommandsTouchable, disabled "/vis/touchable/centre..." and
|
|
"/twinkle" in the case of large process times.
|
|
o Added UI command "/vis/scene/add/endOfRunMacro".
|
|
The macro is executed at end of run and when rebuild required.
|
|
WARNING: some vis commands in the macro cause recursion. Stick to
|
|
simple commmands, e.g., which invoke vis manager Draw() methods.
|
|
o G4ViewParameters: added 'TransparencyByDepth' and
|
|
'TransparencyByDepthOption'. Simplified code; use single TimeParameters
|
|
from G4ModelingParameters, to replace 18 time window parameters.
|
|
Fixed typo to make "/vis/viewer/set/lightsMove cam" behaving correctly
|
|
for "/vis/viewer/set/lightsVector 0 0 1".
|
|
Addressing problem report #2460.
|
|
o G4VisCommandsViewerSet: updated to "/vis/viewer/set/timeWindow"
|
|
commands according to changes in G4ViewParameters.
|
|
Added UI command "/vis/viewer/set/transparencyByDepth".
|
|
o Minor improvement to listing of histograms (if any).
|
|
o In G4VisManager::EndOfRun(), print list of histograms even with vis
|
|
disabled.
|
|
o Modernised macro-based loops with range-based for.
|
|
o Replaced raw for loops with range-for where possible.
|
|
+ modeling:
|
|
o G4TrajectoryDrawerUtils: first version of generic time windowing of
|
|
trajectory slices; draws only slices within the viewer time window.
|
|
Note: unless the viewer can handled time-sliced trajectories (only
|
|
OGLS can do this at present), the viewer must request a kernel visit
|
|
on change of viewer time window.
|
|
Trap trajectories with very long global times, e.g, products of
|
|
long-lived radioactive isotopes. Draw as non-time-sliced trajectories.
|
|
Added fading of trajectory slices if time windowing is active; makes
|
|
trajectory slices look like little meteors streaking across the screen.
|
|
Applied clang-format.
|
|
o G4ModelingParameters: implemented TimeParameters::operator!=().
|
|
Adjusted default values in TimeParameters: set fade factor to 1
|
|
(maximum fading); set head time display 2D x-coordinate to zero
|
|
(centre), while 2D y-coordinate remains at -0.9 (bottom).
|
|
Added struct 'TimeParameters', a prerequisite for "Generic Time-Slicing"
|
|
for the display of the time evolution of events. With that feature, the
|
|
display of tracks moving through time will be available to all vis
|
|
drivers (drivers will still be allowed to implement their own time
|
|
evolution).
|
|
o G4TrajectoriesModel: in DescribeYourselfTo(), draw display head time
|
|
if requested and if time windowing is active; removed Begin/EndDraw
|
|
around the trajectories loop.
|
|
o In G4TrajectoryDrawByEncounteredVolume and
|
|
G4TrajectoryEncounteredVolumeFilter, use G4VTrajectory::GetAttValues()
|
|
instead of CreateAttValues(), to speedup repeated visits.
|
|
o G4VModel: introduced static data member for current modeling parameters
|
|
and its static accessor, GetCurrentModelingParameters().
|
|
o In G4PhysicalVolumeModel, fixed typo in ModelType.
|
|
o G4TrajectoriesModel: call SetCurrentModelingParameters().
|
|
o G4ModelingParameters: added 'TransparencyByDepth' and
|
|
'TransparencyByDepthOption'.
|
|
o G4PhysicalVolumeModel: renamed some data members and access functions
|
|
for clarity; added 'fMaxFullDepth' (includes base path, i.e., from
|
|
world volume); added code for processing transparency by depth.
|
|
+ OpenGL:
|
|
o G4OpenGLQtViewer: fixed the original pick feature to show pick info
|
|
window.
|
|
o G4OpenGLWin32Viewer: added SwitchToMasterThread() method to draw
|
|
trajectories at the end of run in MT mode.
|
|
o G4OpenGLStoredViewer, G4OpenGLStoredQtViewer: initiate kernel visit if
|
|
'TransparencyByDepth' or its options change.
|
|
o In G4OpenGLQtViewer, commented calls to TouchableSetVisibility/Colour;
|
|
no longer needed since the introduction of the new scene tree.
|
|
Commented out some debug printing to std::cout.
|
|
o In G4OpenGLStoredViewer, follow changes introduced in G4ViewParameters.
|
|
+ OpenInventor:
|
|
o G4OpenInventorViewer: initiate kernel visit if 'TransparencyByDepth' or
|
|
its options change. In CompareForKernelVisit(), cause kernel visit if
|
|
viewer start/end time changes; this is to take advantage of the new
|
|
generic time window. Implemented CompareForTransientsRedraw().
|
|
Take advantage of ProcessTransients(), which reconstructs that part of
|
|
the graphical database for transient objects, e.g., trajectories,
|
|
without reconstructing the "permanent" (run-duration) objects, e.g.,
|
|
the detector. In other words, something short of a complete "kernel
|
|
visit". For example, if the time window changes. Maximises the
|
|
efficiency of the recently implemented "generic" time windowing.
|
|
+ Qt3D
|
|
o G4Qt3DViewer: initiate kernel visit if 'TransparencyByDepth' or its
|
|
options change. In CompareForKernelVisit(), cause kernel visit if
|
|
viewer start/end time changes; this is to take advantage of the new
|
|
generic time window. Implemented CompareForTransientsRedraw().
|
|
+ RayTracer:
|
|
o Introducing RayTracerQt. Uses multithreading tracer, G4TheMTRayTracer.
|
|
With multithreading, image construction is quite fast.
|
|
o Introduced nicknames (long names still work): RT (for RayTracer),
|
|
RTX (for RayTracerX), RTQt (for RayTracerQt).
|
|
o In G4RayTracerViewer, use G4Timer to estimate
|
|
KernelVisitElapsedTimeSeconds.
|
|
o In G4VRTScanner (and inherited classes), removed misleading and un-used
|
|
methods GetGSName() and GetGSNickName().
|
|
+ ToolsGS:
|
|
o Allow accumulation of transients (trajectories) during multithreading.
|
|
o Trajectories are stored in the database during the run, and displayed
|
|
at end of run. All events are displayed at end of run.
|
|
o In G4ToolsSGViewer, initiate kernel visit if 'TransparencyByDepth' or
|
|
its options change. In CompareForKernelVisit(), cause kernel visit if
|
|
viewer start/end time changes; this is to take advantage of the new
|
|
generic time window. Implemented CompareForTransientsRedraw().
|
|
Removed 'SwitchToVisSubThread' and 'SwitchToMasterThread' as no action
|
|
is needed on thread switching.
|
|
In mouse_move(), use the event.shift_modifier() method, to pass in pan
|
|
mode. Have GetWindowSize() and GetRenderAreaSize() methods to retrieve
|
|
the actual sizes of the "seen/visible window" and of the "render area"
|
|
size; these may return different sizes, for example with Qt/OpenGL on
|
|
Mac and Windows. In SetView(), use the new GetWindowSize(),
|
|
GetRenderAreaSize() methods to set the "marker scale" on
|
|
G4ToolsSGSceneHandler.
|
|
o G4ToolsSGQtGLESViewer, G4ToolsSGQtZBViewer, G4ToolsSGOffscreenViewer:
|
|
suppressed SetView() method, as no more needed.
|
|
o In G4ToolsSGSceneHandler, respect line width in vis attributes and view
|
|
parameters. In GetOrCreateNode(), removed restriction on multithreading.
|
|
Handle the 'fMarkerScale' field.
|
|
o Modernised macro-based loops with range-based for statements.
|
|
|
|
o Datasets:
|
|

together for ease of use and demonstration. Code/behaviour otherwise
|
|
is unchanged. Including two examples, DICOM1 (renamed from the original

DICOM) and DICOM2, with two libraries that implement capabilities
|
|
common to both applications: G4DicomCore, providing the core Geant4
