GEANT is a simulation program designed to describe the passage of elementary particles through matter. Originally developed for high energy physics experiments, today it has uses in many other fields.

History

The first version of GEANT dates back to 1974. The latest generation is GEANT4, which was developed by the RD44 collaboration in 1994-1998 and is being maintained and improved now by the GEANT4 collaboration (release 7 is the current most recent version of GEANT 4). It has an object-oriented design based on C++. The previous incarnation, GEANT3, is also still in use. Geant4 (for GEometry ANd Tracking) is a platform for the simulation of the passage of particles through matter. ... In computer science, object-oriented programming, OOP for short, is a computer programming paradigm. ... C++ (generally pronounced see plus plus) is a general-purpose programming language. ...
