- Improve conditions handling. Started to implement using simple telescope
detector from C.Burr.
- Add variable DD4HEP_LIBRARY_PATH to be used on MacOSX El Capitane
to overcome DYLD_LIBRARY_PATH protection issues.
- Fix to copy with negative(rebased) IDDDescriptor fields
(affects IDDDescriptor and VolumeManager).
2 New tests:
- ClientTests/Bitfield_SidesTest.xml to test readout string:
system:8,barrel:-2
- ClientTests/Bitfield_SidesTest2.xml to test readout string:
system:16,barrel:16:-5

Due to pressure of the FCC folks, I tried to implement a more DD4hep like implementation of the
the segmentation objects. For testing only CartesianGridXY. If this mechanism works,
it could be a starting recipe for the rest of the segmentations. The draw-back of this approach is,
that assignments are not reversible:
DD4hep::CartesianGridXY xy = readout.segmentation(); // Works
Markus Frank
committed
Reason: the managed objects are different....at some point in time I will have to find a
clean solution for this, but the required changes for such a solution shall be manageable.

Small fixes and extensions of DDEve. Show "Views" menu even if specifying xml on the command line.
Add possibility to specify event data in EveDisplay method, rather than having to select it in the gui dialogue.
Selects FCC EventHandler if specified in the config xml (as an "eventHandler"-attribute to the "display" node),
but keeps default behavior if not.
2016-08-24 M.Frank
Adding first somehow useful implementation to use conditions and the consequent loading thereof.
Used by the DDDB implementation/example. DDDB is an alternative way to populate the DD4hep
detector description using LHCb's detector description database.
The reason is, that only a running experiment has a reasonable base to conditions data
to excercise the DD4hep conditions.
If interested, please have a look in the DDDB examples.
Still TODO:
- A formal way to bootstrap the conditions loading still has to be found.
- Conditions loading from XML files and a small comprehensive example.
Added new MegatileLayerGridXY segmentation for Scintillator strip Ecal, which is implemented by K.Kotera,
- many ( minor fixes ) by F. Gaede, M. Petric, A Sailer, ...

Implement multiple segmentations.
Though one readout objects (associated to one DetElement) may only have on segmentation,
The MultiSegmentation type allows to have several sub-segmentations, which can be chosen
from.
Please see examples/ClientTests/*/MultiSegmentations
At the same time allow the readout object to defined multiple collections through
the IDDescriptor.
Please see examples/ClientTests/*/MultiCollections
The combined example can be found in
Please see examples/ClientTests/*/NestedSegmentations

++++++++++++++++++++ NOTE: +++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- Mega commit. Do not use until green signal arrives with seperate release notice.
+++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
- Package DDDB: Prove of concept, that we can populate the geometry also from other
sources than xml files obeying the lccdd notation.
- DDCore/XML: Implement the possibility to use external entity resolution for Xerces.
There is not equivalent in TinyXML (AFAIK).
- Remove some of the Spirit parsers, since the libraries are getting way too big.
This implicitly assumes, that object properties of 'exotic' types such as
deque<long double> etc. are not really used. If you need properties stay to the obvious:
string, int float, double and vectors, maps and sets thereof!
- DDG4 needed to public the DDG4Python include directory (Now in DDG4/Python).
Reason: try to create ROOT 6 dictionaries, which can be relocated for release purposes.
- ROOT 6 dictionary generation: Create dictionaries with the additional flag:
"-inlineInputHeader" which physically includes the header files used to generate the
dictionaries --> relocatability.
2016-03-21 M.Frank
- Add additional vertex argument to EventReader::readParticles, which supposedly should
2016-03-03 M.Frank
- Improve/complete job options type palette.
- Allow modify the Geant4IsotropGenerator to shoot particle distributions according
to several distributions:
flat in : uniform, cos(theta), eta/pseudorapidity, ffbar (1+cos^2 theta)
Option: generator.Distribution = 'cos(theta)'
Default is uniform.
2016-02-15 A.Sailer
- LCIOStdHepReader.cpp

- select detectors with
DD4hep::Geometry::DetectorSelector(lcdd).detectors( ( DD4hep::DetType::TRACKER | DD4hep::DetType::ENDCAP )) ;
- used in UtilityApps/dumpdetector.cc
- added detector_types.xml with int constants defined in DetType.h, include with :
<include ref="${DD4hepINSTALL}/DDDetectors/compact/detector_types.xml"/>
- add elements to xml, e.g.
<type_flags type="DetType_TRACKER + DetType_ENDCAP + DetType_PIXEL + DetType_STRIP "/>
2016-02-10 M.Frank
DDCond
First implementation of conditions access. Required some movements of files
from DDG4 (Properties) and some changes in the core conditions implementation.
The basic infrastructure is now present. Don't know yet however how buggy it is...

functionality.
- Support for python configuration (see manual for details)
- Support for global Geant4Actions executing in thread reentrant shared mode.
(see manual for details)

DDSurfaces::ISurface/Surface
- added implemation of conical surfaces
- ICone, VolConeImpl, VolCone, ConeSurface
2015-10-13 M.Frank

tests of hits.
2015-10-09 M.Frank
DDG4
- Extend the functionality of the DDG4 plugins
Geant4InteractionVertexBoost and Geant4InteractionVertexSmear.
If the Mask property is set to -1, all interactions present
at call time are smeared/boosted according to the parameters.
Note, that the position of the plugins within the generation
sequence is important.
- Add a new generator Geant4GeneratorWrapper to allow the use
of native G4 generator classes such as the G4ParticleGun or
the G4GeneralParticleSource. Still to be tested.
- Extend the Geant4Random functionality: May now be instantiated
like any other Geant4Action. Users may set the seed or the
luxury level.
All calls to HepRandom (CLHEP) or gRandom (ROOT) will re-use
this instance. See DDG4/examples/CLICRandom.py for illustration.
- Updated DDG4 manual.
2015-09-30 F.Gaede
- updated createGearForILD.cpp to use new parameters in LayeredCalorimeterData
( innerThickness, innerRadLength, etc)
2015-09-15 F.Gaede

a polymorphic pointer of type VolSurfaceBase
- this should facilitate the creation
of dedicated surface classes for special cases
such as inside the beampipe or the face of the calorimeter

provides positions of sensitive slices within a layer with respect to the
center of the layer
2015-07-25 M.Frank
------------------
- DDSegmentation: Remove several 'shadow' warnings.
- New build system for the DD4hep core, which greatly simplyfies the cmake files
for the various sub-packages.

*** Important ***
Before updating, backup your existing and working checkout. Though I was running
the basic tests, there may be unchecked corners of the software.
Notes:
- Backwards compatibility mode for the usage of ROOT 5 and ROOT 6 alternatively.
- For ROOT 6 the Gaudi PluginService is used and added to the distribution.
- DD4hep is distributed with a licence. See $DD4hepINSTALL/LICENSE for details.
- In the doc area the $DD4hepINSTALL/doc/CREDITS file everybode should add her/his
name, if contributed significantly.
- Unfortunately this meant to add/change the headers of all files and give a
pointer to the licence file. If I accidentally changed the author name, please
chagne it back.
- The plugin factory declaration statements were changed to accomodate both
ROOT 5 and ROOT 6 and to keep the number of 'ifdef' statements at a minimum.
- TODO: Properly change the cmake scripts to accomodate for ROOT 6 and the
automatic switch when building DD4hep.
For reference reasons: this commits is revision 1812 + 1813 (DDDetectors)

additional parameters required by Pandora:
inner_phi0 (e.g. alignment for inner symmetry)
outer_phi0 (e.g aligment for outer symmetry)
NOTE: phi0 still remains but is deprecated
gap0 (e.g stave gap along r-phi)
gap1 (e.g middle stave gap along z)
gap2 (reserved for future use)
2015-06-29 A.Sailer
---------------------
- always store lcio collections, even if they are empty in Geant4Output2LCIO (DDG4/ddsim)
2015-06-29 F.Gaede

For backward compatable, by default, do not apply BirksLaw, and apply BirksLaw with call 'doApplyBirksLaw()'.
added optional Geant4ScintillatorCalorimeterAction
- Added one 'Geant4ScintillatorCalorimeterAction' into DDG4 plugins Geant4SDActions for scintillator to take
Geant4 BirksLaw effect as sensitive detector active layer.
F.Gaede
-------
- added SurfaceManager class that holds maps of surfaces for
"world","tracker","calorimeter","passive" and all individual subdetectors
- to be used in reconstruction code where a lookup from cellID
to corresponding surface is needed
- needs plugin "InstallSurfaceManager" to be in the compact file
- access via:
SurfaceManager surfMan = *lcdd.extension< SurfaceManager >() ;
const SurfaceMap& surfMap = *surfMan.map( "world" ) ;
- renamed old SurfaceManager to SurfaceHelper

-----------------------
- Fixed bug in DDG4/lcio/LCIOConversions.cpp, which stored only the PDG of the primary particle
in multiple particle contributions in SimCalorimeterHits instead of both the primary and secondary PDGs.
2015/05/13 Markus Frank

- Fix bug in DDG4, which forced DDG4 to exit if a property from the Geant4 prompt could
not be set. No an error message is printed and the prompt is returned to the user.
(Bug submitted by A. Sailer)
2015/05/11 Andre Sailer
-----------------------
- CMake updates:
- Split libraries into components: use find_package(DD4hep COMPONENTS <component> [...] )
to find the components you need.
- At the moment there are these components are sensible to link against: DDRec, DDG4, DDEve, DDSegmentation
- To link against the librarie use either DD4hep_COMPONENT_LIBRARIES or DD4hep_<COMPONENT>_LIBRARY,
where <COMPONENT> needs to be replaced by the UPPER case name of the component
2015/05/09 Markus Frank
-----------------------
- Allow to access detectors by type from lcdd.
- The sensitive type of a detector is set in the 'detector constructor'.

Christian.Grefe, 2014-07-15
---------------------------
made DDSegmentation optionally a stand-alone package
create DDSgementationConfig.cmake when build as part of DD4hep
Markus Frank, 2014-07-02
------------------------
- add LCIO conversions from DDSim - sensitive detectors
can now simply instantiate LCIO Sim hits
2014/06/30 Markus Frank
-----------------------
- DDG4: Support user (context-) extensions for Geant4.
User contexts are availible for events and runs. The contexts
are accessible from the Geant4Context meber of each Geant4Action,
the base class for all processing entities.
-- Adding a context:
context()->event().addExtension(pointer_to_object, typeid(TYPE), 0);
or
context()->event().addExtension<TYPE>(pointer_to_object);
In the first case the object is NOT DELETED at the end of the event.
In the second case the object is deleted.
-- Accessing the context:
TYPE* ctx = context()->event().extension<TYPE>(false);
The boolean argument indicates if an exception should be thrown
if the extension is not present ie. here no exception.
- DDCore: adjust a few print statements.
2014/06/27 Markus Frank
-----------------------
- Separate XML loading from LCDD implementation.
- New package: DDEve: a bit more sophisticated TEve specialization
To start use examples/CLICSiD/compact/DDEve.xml
DDEve can interface currently to ROOT files created by DDG4.
An example data file is provided as well in:
examples/CLICSiD/compact/CLICSiD_events.root
Documentation is lacking a bit....
start the display with:
$> root.exe ${DD4hepINSTALL}/examples/DDEve/DDEve.C
2014/06/19 Frank Gaede
----------------------
- replaced TGeoUnits.h by DD4hepUnits.h
- renamed namespace tgeo to dd4hep
-> users need to replace tgeo::mm by dd4hep::mm
2014/06/12 Frank Gaede
----------------------
- changed default unit for angles to be radians (tgeo::rad = 1.)
- enforce usage of units from TGeoUnits.h in xml expression evaluators
- convert to degrees for angles in TGeoShapes constructors
- NB: there is one inconsistency left here: angles returned
from TGeoShapes are already in degrees, this is the one
case where a quantity returned from DD4hep/TGeo does not have the default
units - thus one should not write
double phi = coneSeg.Phi1() / tgeo::rad ;
but rather
double phi = coneSeg.Phi1() * tgeo::deg ;
2014/06/03 Markus Frank
-----------------------
- Provision for ROOT persistency for DD4hep detector descriptions:
Create Cint dictionary for DD4hepCore by default when building the library.
For the time being the area of DDSegmentation is left out, since these
objects require changes due to the handling of references and template
specializations. Besides these, DD4hep detector descriptions can be
saved and read-back directly to/from ROOT files - which may improve
a lot the startup time of processes.
- The DDG4 dictionary is created by default when building the library.
When importing DDG4 from python only the DD4hepCore DD4hepG4 libraries
must be present. It should no longer be necessary to compile the
necessary AClick on the fly.
- Investigations on wirframe drawing:
Wireframes are a property of the scene graph. You can toggle to wireframe
using the 'w' key on the keyboard. Other representations are
'r': Solid view
't': Solid + wireframe view.
This information is accessible from the help menu of the ROOT OGL widget.
2014/05/28 Markus Frank
-----------------------
- Several fixes and improvements in DDG4
- Cache output levels in Geant4Kernel object
- Add shell handler to measure energy escape e.g. in calorimeters
- Fix bug in Polycone shapes concerning angles.
IMPORTANT: If you forked the repository examples/CLICSiD
your PolyconeSupport does not work anymore, because the angles
were given in degrees. They should be given in radians!
2014/05/21 Markus Frank
-----------------------
- Fix material creation from XML
JIRA bug: DD4hep - DDFORHEP-4
https://sft.its.cern.ch/jira/browse/DDFORHEP-4
using <composite> in material xml files results in wrong material properties
- Fix JIRA bug: DD4hep - DDFORHEP-3
https://sft.its.cern.ch/jira/browse/DDFORHEP-3
Recursive assemblies result in error in TGeo geometry
Bug results in errors when closing the geometry like:
"Error in <TGeoVoxelFinder::SortAll>: Wrong bounding box for volume SIT_assembly"
- Provision to store survey constants to the DetElement as an extension
for Alignment calculations (priv. comm. C.Parkes)
- Fix bug in expression evaluation of angles.
All detector constructors receive angles in "rad". No correction
from degree to rad should be necessary.

2014/05/21 Frank Gaede
-----------------------
- add MaterialManager class providing
- access to materials at any point or on straight
line between two points
- creation of material with averaged properties (A,Z,rho,x0,Lambda)
- added utility print_materials to print material properties along
a straight line between two points including integrated radiation and
interaction lengths (useful for debugging geometries and materials)
- use avaeraged material for Surfaces where the thickness extends
beyond the volume boundaries
- introduced new simple data class MaterialData for this
*** known issues
** materials don't work for detectors with assemblies in assemblies
as the TGeo navigation dose not seem to work:
Error in <TGeoVoxelFinder::SortAll>: Wrong bounding box for volume SIT_assembly
-> ROOT bug or feature ?
** using <composite/> in compound materials results in incorrect material properties
see ILDExDet/compact/materials Polysterene as example
2014/05/06 Frank Gaede
-----------------------
- DDSurfaces/DDRec:
- added ICylinder and CylinderSurface to provide
access to cylinder radius for the tracking
- teveDisplay:
- draw sensitive surfaces in red and helper surfaces in gray
- protect against missing lcio input file
- reduced printout from VolumeManager (changed INFO to DEBUG)
2014/04/05-2014/04/29 Frank Gaede
---------------------------------
- Implementation of Surface classes for track reconstruction
- abstract interfaces in DDSurface: ISurface and IMaterial
- implementation in DDRec: Surface, SurfaceManager, DetectorSurfaces
- basic functionality exists:
- meassurement surface vectors u,v, normal and origin
- check if point is inside the bounds of the corresponding volume
- currently the material is taken to be the one from the volume
-> to do: average material if surface thicknesses extend beyond the
volume for comound materials
- added drawing of surfaces and (Sim)TrackerHits and (Sim)CalorimeterHits to teveDisplay
( link lcio file to teve_infile.slcio )
- added some surfaces to ILDExDet: VXD, SIT, TPC
- added test_surfaces to ILDExSimu
(fails currently for some hits that are not created on the surface ...)
- added some assemblies to ILDExDet to better structure the geometry hierarchy
2014/04/28 Markus Frank
------------------------
- First attempt to understand fully the handling of recursive assemblies
from the 2014/04/25 was apparently with limited success. Now they should
work!
2014/04/25 Markus Frank
------------------------
- Moved boost::spirit parsers to DDCore, since these parsers are also used
in other packages such as DDCond and DDAlign - whenever strings have to be
converted to objects.
Consequently, the boost spirit code fragments were removed from DDG4.
- Improved and more correct type checking when assigning handles
- Explicit implementation of the object extension mechanism to be used
through inheritance or aggregation rather than having seperate and nearly
identical implementations for various objects.
- Improved defintition of basic objects describing Conditions and Alignment.
- Improved implementation of DDAlign, the alignment support.
Not to be used currently - experimental package.
- Initial implementation of DDCond the package supporting the handling of
conditions.
Not to be used currently - experimental package.
- Geant4Converter: I convinced myself, that the bug in handling assemblies
of assemblies is resolved. To be tested though.
2014/02/07 Frank Gaede
-----------------------
- added DDGear, support for interfacing to gear for backward compatibility
- lives currently in ILDExDet ( should become (optional) part of core DD4hep)
- users need to GearParameter objects as extensions to the DetElement
-> see ILDExTPC_geo.cpp, ILDExVXD_geo.cpp, ILDExTPCSIT_geo.cpp as examples
- program convertToGear creates gear xml file from compact file
( only if GearParameter objects are avialble as extensions)
- added test_convert_ild_gear
- fixed geometry in ILDExVXD_geo.cpp, ILDExTPCSIT_geo.cpp
wrt. to position of support ans sensitive ladders
--------
| v00-06 | sixth beta release ...
--------
2014/02/04 Frank Gaede
-----------------------
- fixed environment scripts thisdd4hep.sh and this${PackageName}.sh
to also export library pathes for external libraries (CLHEP, LCIO, gear)
- added some simple tests to ILDExDet, ILDExSimu and noviceN04
- provide cmake script run_test_package.sh ( configured as run_test_${PackageName} )
to call test binaries after initializing the environment
(needed for automated/nightly tests)
- updated Readme.txt wrt build procedure and running the tests
2014/01/17 Markus Frank
--------------------------
- Prepare implementation of Alignment using Release and Grap features of TGeoVolume
and TGeoNode. In principle this was done in a backwards compatible way, but
I cannot really check 100% the #ifdef's.
- Fix handling of XML collections using XercesC.
(Bug reported by P.Kostka).
- Fix several compiler warnings issued by Coverity.

--------------------------
- Whole load of fixes to keep coverity quiet....
- Fix bug in DDG4 field interface component
- Allow the usage of units, positions and lorentzvectors and in DDG4 properties.
Example using a position property (ROOT::Math::XYZVector):
Idle> /ddg4/Gun/position (1*mm,1*cm,0.01*m)
Geant4UIMessenger: +++ Gun> Setting property value position = (1*mm,1*cm,0.01*m)
native:( 1 , 10 , 10 ).
- Support for std::vector<T>/std::list<T>/std::set<T> properties.
- Support for include directives of the format
<include ref="file-name"/>
for the top level <lccdd> tags
Parent tag Included root tag Data content
-- <lccdd> <define> See below.
<detectors>
<detector>
<display>
<lccdd> Nested includes (with DTD validation for Xerces-C)
-- <define> <define> Set of constants
-- <detectors> <detector> Single XML subdetector description
-- <detectors> <detectors> Multiple XML subdetector descriptions
-- <display> <display> Set ov visualization attributes
DTD validation is only performed using Xerces-C for root tags <lccdd>.
Note:
<lccdd> include directives are executed BEFORE any other directive!
Other include directives are executed BEFORE the corresponding named directive!
2013/11/14 Markus Frank
--------------------------
- Reformat files in DDCode and DDG4 to remove the <TAB>s from the source files.
Hopefully the content is now more readable.
- DDCore: Remove empty and named constructors for shapes. Empty constructors
were simply a dangerous hook to memory leaks, named constructors are
deprecated since along time.
- DDG4: add support for messengers to access and modify properties from
the Geant4 prompt. For the test hit classes and the simple sensitive
detector a ROOT I/O plugin was provided.
- DDG4: Split into several libraries:
-- libDDG4.so pure link library without any plugins
-- libDDG4Legacy.so 'Old' plugins. The old stuff at some point
-- libDDG4Plugins.so New framework plugins
-- libDDG4LCIO.so LCIO output plugin for new framework

--------------------------
- doc: Add CHEP2013 paper about DD4hep as a start of the documentation
section. More to come hopefully.
- DDCore: several small improvements:
- Segmentations are no longer Ref_t's.
- Base internal implementing object directly on the segmentations
