• Use G4OpticalParameters in geant4.10.7 and newer

2021-09-06 Andre Sailer (PR#863)

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

2021-08-31 Markus Frank (PR#867)

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

2021-08-30 Markus Frank (PR#866)

• 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: https://github.com/AIDASoft/DD4hep/issues/813 , https://github.com/AIDASoft/DD4hep/issues/858

2021-08-25 Markus Frank (PR#865)

• 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 https://github.com/AIDASoft/DD4hep/issues/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:
```  det = str('EcalBarrel')
  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'
...

• Optionally import gdml physvol below top level, avoiding world

2021-08-03 Valentin Volkl (PR#855)

• [testing] separate import test for ddg4 and rest of dd4hep

2021-07-29 Markus FRANK (PR#853)

• Implement fix as proposed in issue https://github.com/AIDASoft/DD4hep/issues/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"/>

2021-07-22 Whitney Armstrong (PR#849)

• Fix G4Sphere construction to use delta theta/phi instead of TGeo's ending angles phi2/theta2.

• EDM4hepOutput: On collection creation for EDM4hep, save CellIDEncodingString

2021-06-24 Thomas Madlener (PR#843)

• Explicitly enable C as language to avoid problems in the build file generation step of cmake (see spack/spack#24232)
