Beginners Guide (FAQ)

Posted on November 5, 2020

Overview The dd4hep environment has tools envisioned for detector simulation for the next generation of experiments. These are very powerful and flexible tools, and so, if you are just beginning coding or if your coding skills are a bit rusty, you may need some help to navigate their complex environment. This document may help you get started. This tutorial assumes you have some familiarity with GEANT4, a very powerful program for describing detector geometries and simulating particle interactions with matter. [Read More]

Features

The Compact Description The compact detector description is based on concepts of the linear collider detector simulation. The compact description is provided in XML format, has a minimalistic form and was designed with the aim for conceptual design studies. Since the parsers of DD4hep do not validate the schema of the XML it facilitates simple addition of new elements and attributes into the detector description. The information in the XML is per-se not enough for a comprehensive detector description. [Read More]

About

Posted on November 20, 2017

About DD4hep For a long time, high energy physics experiments have been striving to develop software tools for the complete description of detector models based a single source of information. For the success of an experiment it is important to provide a consistent detector description to simulation, reconstruction and analysis applications from a single source. When referring to the detector description this includes, in addition to the geometry and the materials used in the device, also parameters describing e. [Read More]

v01-31 2025-01-27 Andrii Verbytskyi (PR#1378) Use standard locations if the LD_LIBRARY_PATH or ROOTSYS are empty, i.e. /usr/lib,usr/lib64, etc. 2025-01-25 Markus Frank (PR#1390) Optimize the Geant4VolumeManager. Instead of mapping the Geant4 pathes as vectors of pointers, hash64 the pointers of the path and lookup pathes from the touchable history using this key. Relevant changes are in the files DDG4/Geant4GeometryInfo.h and src/Geant4VolumeManager.cpp. Everything else is only cosmetics. [Read More]
