  • DDSim: add possibility for users to inject configurations for their own output plugins. See example in OutputConfig section of the steering file

  • Mainly update reference files for CAD shape tests, since the order of the vertices changed when adding facets
    with vertex indices rather than coordinates.

  • The export of beoolean shapes (union, subtraction, intersection) to was not properly working
    and actually casued segment vialotions. This PR fixes the problem and handles these shapes
    properly using the RootCsg operations for boolean shapes.
  • Examples geometries were provided by Gerri from FCC: examples/ClientTests/compact/FCCmachine and files thereein.
  • Test example is in DDCAD: DDCAD_export_FCC_machine and DDCAD_import_FCC_machine
  • This PR addresses the issues: #813 , #858

  • In cmake tests use the macro ${Python_EXECUTABLE} to invoke the python interpreter rather than
    only python.
  • if FIND_PACKAGE(Python ${REQUIRE_PYTHON_VERSION} EXACT QUIET COMPONENTS Interpreter)
    does not resolve the python executable fall back to python${Python_VERSION_MAJOR}.

• 2021-08-24 Markus FRANK (PR#864)

  • Support for multiple readouts or (G4VUserParallelWorld equivalent)
    Issue #861
    Example:
    examples/CLICSiD/compact/SiD_ECAL_Parallel_Readout.xml +
    examples/CLICSiD/scripts/SiD_ECAL_Parallel_Readout.py

    For a given subdetector the sequence of sensitive actions can be enhanced
    having multiple sensitive actions where each one can have its own Readout
    definition. Hence each action can produce its own set of hits depending on the
    readout geometry (segmentation).
    in XML these readout structures must first be defined:

    <readouts>
      <readout name="EcalBarrelHits">
        <segmentation type="CartesianGridXY" grid_size_x="3.5" grid_size_y="3.5" />
        <id>system:8,barrel:3,module:4,layer:6,slice:5,x:32:-16,y:-16</id>
      </readout>        
  
      <readout name="EcalBarrelHits_0">
        <segmentation type="CartesianGridXY" grid_size_x="1" grid_size_y="1" />
        <id>system:8,barrel:3,module:4,layer:6,slice:5,x:32:-16,y:-16</id>
      </readout>        
   ....
    </readouts>
  
  

  and can then be assigned to the sensitive actions in the python setup:

    typ = sid.geant4.sensitive_types['calorimeter']
    seq = DDG4.SensitiveSequence(sid.kernel, str('Geant4SensDetActionSequence/') + det)
    seq.enableUI()
    act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler'), det)
    act.enableUI()
    seq.add(act)
    # Add extra parallel readout action with readout EcalBarrelHits_0
    act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler_0'), det)
    act.ReadoutName = 'EcalBarrelHits_0'
    act.enableUI()
    seq.add(act)
    # Add extra parallel readout action with readout EcalBarrelHits_1
    act = DDG4.SensitiveAction(sid.kernel, str(typ + '/EcalBarrelHandler_1'), det)
    act.ReadoutName = 'EcalBarrelHits_1'
  ...

  • Implement fix as proposed in issue #850.

• 2021-07-27 Whitney Armstrong (PR#851)

  • Using ref="OtherVisName" attribute with the vis tag, the visualization attribute is an extension of
    "OtherVisName" which is used to initialize the new vis attribute.
  • The new VisAttr inherits all the properties of the ref and additional arguments override these values.

  Example where the only difference is the alpha value.

    <vis name="SiVertexBarrelModuleVis"
         alpha="1.0" r="1.0" g="0.75" b="0.76"
         drawingStyle="wireframe"
         showDaughters="false"
         visible="true"/>
  
    <vis name="SiVertexEndcapModuleVis"
         ref="SiVertexBarrelModuleVis"
         alpha="0.5"/>
