  • To fix issue #466 we had to go back to the original implementation which was actually correct (see 36d4b01#diff-7219d47bc4ab7516e0ca6c4f35f2602f).

  • Added an example to show how to perform scans of the volume hierarchy with user defined callback functors. See for details examples/ClientTests/src/PlacedVolumeScannerTest.cpp.

  • Added conversion between TGeoArb8 and G4GenericTrap, fixes #465

• 2018-12-05 Markus Frank (PR#467)

  • Harmonize argument names in Shapes.h with their actual functionality. For many shapes in DD4hep/Shapes.h the argument names were misleading: very often deltaPhi was mentioned, whereas the code actually used instead of (phi, deltaphi) the input arguments to the ROOT constructors (startPhi,endPhi) or (phi1, phi2). Wherever ROOT uses (startPhi,endPhi) the argument names were changed accordingly. Please note a bug was found in the legacy constructor:

      /// Legacy: Constructor to create a new identifiable tube object with attribute initialization
      Tube(const std::string& nam, double rmin, double rmax, double dz, double startPhi, double endPhi)

    Here opposite to all other constructors delta_phi was used as such - in contradiction to other constructors of the same class. This was rectified.

  • Introduce compile flag to minimize conditions footprint

• 2018-11-27 Markus Frank (PR#461)

  • Add shape constructor for regular trapezoids (TGeoTrd1) ( see #460). Trd2 cannot be divided the same way as Trd1 shapes. Hence the addition became necessary. Due to the imprecise name of Trapezoid the names Trd1 and Trd2 (aka old Trapezoid) are favored. The usage of Trapezoid is supported for backwards compatibility using a typedef.

• 2018-11-13 Markus Frank (PR#457)

  Provide support for Volume divisions.

  Since DD4hep requires Volumes (aka TGeoVolume) and PlacedVolumes (aka TGeoNode) to be enhanced with the user extension mechanism, therefore shape divisions must be done using the division mechanism of the DD4hep shape or the volume wrapper. Otherwise the enhancements are not added and you will get an exception when DD4hep is closing the geometry or whenever you do something with the volume, which is served by the user extension. The same argument holds when a division is made from a Volume. Unfortunately there is no reasonable way to intercept this call to the TGeo objects - except to the sub-class each of them, which is not really acceptable either.

  Hence: If you use DD4hep: Never call the raw TGeo routines.

  For any further documentation please see the following ROOT documentation on TGeo

  For an example see examples/ClientTests/src/VolumeDivisionTest.cpp
  and examples/ClientTests/compact/VolumeDivisionTest.xml

  Implementation of non-cylindrical tracking region (resolves #371)

  • It is possible to define volumes in a parallel world such as e.g. a tracking region. In principle any volume hierarchy may be attached to the parallel world. None of these volumes participate in the tracking as long as the "connected" attribute is set to false. The hierarchy of parallel world volumes can be accessed from the main detector object using

    dd4hep::Volume parallel = dd4hep::Description::parallelWorldVolume()

  This parallel world volume is created when the geometry is opened together (and with the same dimensions) as the world volume itself.

  • IF the NAME of the volumes is "tracking_volume" within the compact notation it is declared as the Detector's trackingVolume entity and is accessible as well:

    dd4hep::Volume trackers = dd4hep::Description::trackingVolume()

  • Although the concept is available in the DD4hep core, it's configuration from XML is only implemented for the compact notation. For details see the example examples/ClientTests/compact/TrackingRegion.xml.
  • If the volume should be connected to the world: connected="true". This is useful for debugging because the volume can be visualized else if the volume is part of the parallelworld: connected="false". The volume is always connected to the top level. The anchor detector element defines the base transformation to place the volume within the (parallel) world.

       <parallelworld_volume name="tracking_volume" anchor="/world" material="Air" connected="true" vis="VisibleBlue">

  Enhancement of assemblies, regions and production cuts (resolves #373)

  On request from FCC particle specific production cuts may be specified in the compact notation. These production cuts (Geant4 currently supports these for e+, e-, gammas and protons) are specified as "cut" entities in the limitset. (See the example examples/ClientTests/compact/Assemblies.xml).

  • The hierarchy of cuts being applied is:
    • If present particle specific production cuts for a region are applied.
    • else the "cut" attribute of the compact region specification is used
    • else the global Geant4 cut is automaticallly applied by Geant4.

  SensitiveDetector types not changed by Geant4SensDetActionSequence (resolves #378)

  The sensitive detector type defined in the detector constructors is no longer changed intransparently in the back of the users. This may have side-effects for creative detector constructor writers, who invent ...

    • A long standing bug was fixed for the test t_AlignDet_Telescope_align_new.

    • Moved to path dependent ordering. Test now OK.
    • Closes #282

    • Please see #288 for details.
    • The main interface was not changed. Rather a view to the Detector class supports this functionality.
    • The existing view dd4hep::DetectorLoad was enhanced to allow the required functionality:

     Detector detector = ....;
     /// So here is the actual test: We parse the raw XML string
     DetectorLoad loader(detector);
     loader.processXMLString(buffer,0);

    • An example was added (ClientTests/src/XML_InMemory.cpp, which illustrates the usage).

  DDG4 enhancements

  • Enable framework support in DDG4. The Geant4Context is the main thread specific accessor to the dd4hep, DDG4 and the user framework.

    • The access to the dd4hep objects is via the Geant4Context::detectorDescription() call,
    • the access to DDG4 as a whole is supported via Geant4Context::kernel() and
    • the access to the user gframework using a specialized implementation of:
      template <typename T> T& userFramework() const;

    A user defined implementations must be specialized somewhere in a compilation unit of the user framework, not in a header file. The framework object could host e.g. references for histogramming, logging, data access etc.

    This way any experiment/user related data processing framework can exhibit it's essential tools to DDG4 actions.

    A possible specialized implementations would look like the following:

      struct Gaudi  {
        IMessageSvc*   msg;
        IHistogramSvc* histos;
        ....
      };
      template<> Gaudi& Geant4Context::userFramework<Gaudi>()  const  {
        UserFramework& fw = m_kernel->userFramework();
        if ( fw.first && &typeid(T) == fw.second ) return *(T*)fw.first;
        throw std::runtime_error("No user specified framework context present!");
      }

    To access the user framework then use the following call:

    Gaudi* fw = context->userFramework<Gaudi>();

    of course after having initialized it:

      Gaudi * fw = ...;
      GaudiKernel& kernel = ...;
      kernel.setUserFramework(fw);

  • G4RunManager is now a plugin. To enable user defined run managers in DDG4, the run manager is encapsulated in a Geant4Action. See DDG4/plugins/Geant4RunManagers.cpp how to implement such plugins. Currently there are to factories implemented:

    • G4RunManager -> factory invokes the single threaded G4RunManager
    • G4MTRunManager -> factory invokes the multi threaded G4MTRunManager

    The factory names here are identical to the names of the native G4 classes.
