GeoModel - Its History and its Team

The GeoModel libraries have been initially designed and developed as part of the software for the ATLAS Experiment at CERN.

The GeoModel Toolkit is now fully open-source and available to everyone, and all contributions are more then welcome.

Development History

(All contributors on this page are listed in alphabetical order)

The original, ATLAS-only version of the GeoModelKernel library was developed by Joseph Boudreau and Vakhtang Tsulaia, and presented at CHEP 2004 1.

The GeoModelKernel library has been extracted from the ATLAS software and completed with an I/O library by Riccardo Maria Bianchi and Joseph Boudreau, and presented at CHEP 2016 1.

The new, open-source, and extended GeoModel Toolkit has been designed and developed by Marilena Bandieramonte, Riccardo Maria Bianchi, Joseph Boudreau, Andrea Dell’Acqua, and Vakhtang Tsulaia; it has been presented at CHEP 2019 1.

The list of all contributors can be found in the Contributors page.
