GeoModel --- A user-friendly C++ Toolkit for HEP Detector Description
GeoModel is a user-friendly C++ Toolkit and Suite for HEP Detector Description with minimal dependencies.
Dependencies
The philosophy of the whole GeoModel Suite is to keep the external dependencies at the minimum.
The core packages only depend on these third-party libraries:
- Eigen3, as the maths library (header-only)
- SQLite, as the underlying format to store detector description data
- fmt, as formatting library (header-only)
Structure
Build tree
By default, only the base classes are built:
- GeoModelCore
- GeoModelKernel
- GeoGenericFunctions
- GeoModelIO
- GeoModelDBManager
- GeoModelWrite
- GeoModelRead
- TFPersistification
On request, additional packages, libraries, and tools can be built:
- GeoModelTools
- ExpressionEvaluator
- GeoModelJSONParser
- GeoModelXMLParser
- GMCAT
- GeoModelVisualization (
gmex) - GeoModelExamples
- GeoModelG4
- GeoMaterial2G4
- GeoModel2G4
- FullSimLight
Note:
Some of the optional packages bring in additional dependencies, for example libraries to handle 3D graphics and Geant4 for standalone detector simulations.
In particular, these are the additional dependencies and the packages that bring them:
- GeoModelTools: Xerces-C, nlohmann_json
- GeoModelVisualization: Qt5, Coin3D, SoQt, nlohmann_json
- Examples about the classes handling the GeoModel->Geant4 translation: Geant4
- GeoModelG4: Geant4
- FullSimLight: Geant4
