Change options _WITH_ to _USE_
Print Warning that variables with _WITH_ are deprecated
Change Defintions to _USE_ as well
Add REQUIRED to find_package geant4 and xercesc if they are turned on
Updated documentation
Updated ILDExDet example
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.

| v00-07 | seventh beta release ...
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.

2013/12/17 Markus Frank
--------------------------
- 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:
-- libDD4hepG4.so pure link library without any plugins
-- libDD4hepG4Legacy.so 'Old' plugins. The old stuff at some point
will have to disappear.
-- libDD4hepG4Plugins.so New framework plugins
-- libDD4hepG4LCIO.so LCIO output plugin for new framework

committed
2013/11/03 Markus Frank
--------------------------
- 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
classes from Christian.
- Rearrangement of some code from Handle.h to Primitives.h
- Allow to attach extensions to LCDD
- DDG4: Fix Frank's simulation problem, which he caused himself
introducing his famous factories....
- DDG4: First attempt to fix simulation problem with mignetic field.
Ready for testing.
- DDG4: First commit of a independent simulation aimed for LHCb and LHeC
+ other newcomers. Documentation needs to be written.
Features:
- Modular setup of all Geant4 action routines as plugins, including the
Run-, event-, tracking-, stacking-, stepping- and generator-actions
as well as the physics lists with particle and physics constructors.
- Setup is possible in XML or with C++ either as an AClick in root or
standalone. Python based starter to come.
- Missing is a modular description of the G4 UI and VIS manager(s).
- Documentation is to come. Before documentation is not present
the usage is discouraged.
Note:
- This version of DDG4 uses boost::spirit. It will compile without
the BOOST include files and the old functionality is preserved,
but it will not work.
To use BOOST add to the cmake statement the following tags:
cmake <regular tags> \
-DDD4HEP_USE_BOOST=ON \
-DBOOST_INCLUDE_DIR=${BOOST_INCLUDE_DIR} ....
Where BOOST_INCLUDE_DIR should point to the boost header directory.
BOOST libraries are not used.
2013/10/18 Markus Frank
--------------------------
- Throw exception if the expression evaluator sees a problem.
The message printed before was often not seen.
- Improve printout on exceptions and plugin abortion
- Remove the typedef RotationZYX -> Rotation and
import the type RotationZYX from ROOT::Math.
Markus Frank
committed
- Add more explicit error messages in case a plugin is not found.
- Add file TGeoUnits.h, which allows to use the "usual SystemOfUnits"
from CLHEP using TGeo with the namespace tgeo::xxx
Example: tgeo::mm -> 0.1 (Geant3: cm, sec, GeV, degree)
::mm -> 1.0 (Geant4: mm, nsec, MeV, radian)
I hope I got all translations right.
Geant4 Geant3
----------------------------------------------------------------
millimeter mm=1,cm=10 centimeter mm=0.1,cm=1
nanosecond s=1e9 second ns=1e-9,s=1
Mega electron Volt GeV=1e3 GeV GeV=1
radian rad=1 degree rad=180/pi
Unclear to me was if in Geant3 steradian is also 2*2*pi or 2*2*180 degree.
No-date F. Gaede
-------------------
- changes to build system:
(see ReadMe.txt for details)
- moved examples to ./example directory
- they are not built as part of DD4hep anymore
- install thisdd4hep.sh in ./bin
(modified to have the correct pathes)
- added -DINSTALL_DOC=on/off option
to build doxygen documentation (in ./doc/html/index.html)
- create DD4hepConfig.cmake for easy building against DD4hep
( see examples CMakeLists.txt)
- fixed doxygen API documentation (C.Rosemann)
(greatly improved with many graphs)
--------
| v00-04 | fourth beta release ...
-------- - placement options are now compatible with geant4
- fixed Geant4SensitiveDetector::getVolumeID()
- modified ILDEx model to not use assemblies (for now !?)
- removed obsolete geant4 example ILDEx
- Fix population procedure of volume manager
- Fix uniqueness of volume identifiers.
- Remove call with lookups by placed volume to the volume manager
- improved ILDEx toy example:
- fixed creation of cellIDS for simhits
- creates SimTrackerHits for VXD, SIT and TPC
- creates SimCalorimeterHits for AHcal barrele and endcap
- works now wigth ILDExSimu _and_ SLIC if no assemblies are used
- assemblies work with the DD4hep Geant4Converter and VolumeManager
- added a prototype example for a ROOT independent
plugin mechanism for SensitiveDetectors
- added example implemetation for Calice test beam
calorimeters: CaliceTbeam (Shaojun Lu, DESY)
2013/21/06 Markus Frank
--------------------------
1) Since the placement model for combined translations and rotations
caused more confusion than good, it was agreed to move to a more
Geant4 like placement model using Vectors, Rotations and Transformations
from ROOT::Math. To place a physical volume only one of these
is allowed as an argument: either a rotation or a translation
for simple placements. Combinations may be constructed with Transform3D
objects allowing more complicated placements.
The same mechanism was applied for the operations to construct
boolean solids.
2) The CLICSid Examples were updated according to the changes necessary
from 1)
3) The Tesla drivers from the ILDExDet example were removed. They are
not compliant to 1).
4) The G4 package allows now to translate TGeo geometries to Geant4.
Visual inspection has shown an agreement between the two geometries.
5) The TGeo to LCDD/GDML conversion is still buggy. Hence, simulations
using slic as an engine do not yet work. This is being looked at.
IMPORTANT NOTICE:
The changes described in 1) may affect existing detector constructors.
Unless all problems are solved you should be careful to move to the svn
head. In any case save your checkout or use the tag v00-03.
--------
| v00-03 | third beta release ...
-------- - broken geometry (for some rotations/translations)
- 'backup release' before placement options
will be reduced

2013/02/06 Markus Frank
--------------------------
1) Simplyfy inheritance for common objects from TNamed.
Use direct inheritance of Object from TNamed rather than hidden
using the Value<a,b> construct.
2) Added physical volume manager to simplyfy the detector element
and sensitive detector lookup from a given physical volume.
This implies: If the volume manager is instantiated, the readout specifiers
MUST be correct. This is in most xml files NOT the case.
The "system" field holding the sibdetector-id is MANDATORY!
Otherwise you will receive messages like this:
Exception:SITCollection: This ID descriptor has no field with the name:CellID0
while programming VolumeManager. Are your volIDs correct?
3) To check the volume identification, add argument -volmgr to geoConverter,
geoDisplay, etc.
4) To trace possible memory leaks:
export DD4HEP_TRACE=Yes
then run you converter etc. At the end a table is displayed with a "leakage"
column, showing how many objects were not deleted.
+----------------------------------------------------------------+
| I n s t a n c e c o u n t e r s b y T Y P E I N F O |
+----------+---------+-------------------------------------------+
| Total | Leaking | Type identifier |
+----------+---------+-------------------------------------------+
| 13| 0|DD4hep::Geometry::DetElement::Object
| 3| 0|DD4hep::Geometry::SensitiveDetector::Object
| 3| 0|DD4hep::Geometry::Readout::Object
| 1| 0|DD4hep::Geometry::OverlayedField::Object
| 1| 0|DD4hep::Geometry::CartesianField::Object
....
Ideally the second column only has "0"s. Instances of 1 may be OK (singletons).
Prenotice:
As soon as ROOT v 6.00 is out, we will have to use it!
Andrei kindly agreed to implement a few changes to TGeo, which will make
life much easier and the implementation cleaner and less cumbersome.
--------
| v00-01 |
--------
- first beta release...
2013/20/03 Markus Frank
--------------------------
1) Finished the compact->lcdd converter
Extract lcdd information
$ > geoConverter -compact2lcdd -input file:<compact-input-xml-file> -output <detector>.lcdd
$ > <SimDist>/scripts/slic.sh -o output.slcio -g SiD.lcdd -m <geant4-macro>.mac -r 100
2) Finished the compact->gdml converter
Full GDML cycle can be tested (deplace <detector> with some meaningful identifier):
a) Extract gdml information
$ > geoConverter -compact2gdml -input file:<compact-input-xml-file> -output <detector>.gdml
b) Extract visualisation hints to csv file
$ > geoConverter -compact2vis -input file:<compact-input-xml-file> -output <detector>.vis.csv -ascii
c) Load GDML into ROOT:
$ > root.exe ../doc/gdml_root.C+\(\"<detector>\"\)
The macro expects *at least* the <detector>.gdml file. If no visualisation
information is found, the resulting graphics however is not very nice!
2013/22/02 Markus Frank
--------------------------
1) Today a decision was taken to remove all _X() and _A() macros
accessing static unicode strings. A common macro will be used to
address both XML elements and XML attributes using the macro _U(...).
The original usage only created confusion.
All _X and _A macros were replaced by _U.
2) Improve the executables running the plugin mechanism in UtitlityApps.
They now complain if the plugin was not found.
2013/21/02 Markus Frank
--------------------------
Require strict checks for the existence of xml attributes.
e.g. default=false for Element::attr<bool>() is no longer an option.
if the attribute is not present in the element, an exception
is thrown.
Slightly change the factory method for creating detector elements.
Use a more generic pattern do support also more generic XML
processing.
Install rootmap mechanism for the usage of plugins.
It is no longer necessary to have separate programs
for the various detector models (ILD/SiD).
One generic display program servest them all.
==> Creation of package DDExamples/UtilityApps
example: $> bin/displayGeo -compact <compact-xml-file>
This move has another consequence:
All libraries are build into a common install area:
the <build directory>/lib.
All executable binaries are build into a common install area:
the <build directory>/bin.
The LD_LIBRARY_PATH and PATH variables as defined in
'thisdd4hep.(c)sh' do include these directories
DD4hep release notes. Better start them late than never.
If you perform significant changes to the DD4hep core,
plase leave a small notice here.
