Quick DD4hep howto

DD4hep stands for Detector Description for HEP, a software package developed in the context of AIDA WP2. DD4hep is based on the ROOT geometry framework TGeo and thus allows to use all its features. DD4hep provides representations of all TGeo shapes and means to place them in a hierarchy of detector elements with additional information, which is the core feature of DD4hep.

Glasgow DD4hep Installation

Getting the software to run and trying some of the simple examples looks fairly simple according to this readme. However, there are a few things to be aware of:

On a Mac (did not work) because of too many components not being available

On a Linux box with ILCSoft already installed. Without the ILCSoft components, one has to install many dependencies and soon it get very complicated. Beware of Root older than 5.34.05 that may be not compatible with the latest DD4hep.

SiD Example

After DD4hep is installed as described in the previous section, one can try the SiD example:

source /afs/phas.gla.ac.uk/data/ilc/software/ilcsoft/v01-17/init_ilcsoft.sh
cd DD4hep/examples/CLICSiD
source ../../bin/thisdd4hep.sh
mkdir build; cd build
cmake ..
make -j install

source ../bin/thisCLICSiD.sh
cd ../../..
./bin/geoDisplay examples/CLICSiD/compact/compact.xml

DDSim package

DDSim is a collection of detector geometries for the linear collider detector studies and can be downloaded separately from here.
