Introduction

Adding a new geometry

Generally, in a Geant4 application the detector geometry (i.e., all solid, logical and physical volumes that model your detector) is implemented in a class derived from G4VUserDetectorConstruction that is later passed to the G4RunManager in the main() function. This approach makes impossible the reuse (beyond the copy and paste) of such a geometry to build another one (say, for instance, that you want to use the geometry of a PMT you defined already in a new detector full of them).

To solve this problem, NEXUS adds an additional OO layer of abstraction by encapsulating the geometry descriptions in classes derived from BaseGeometry.
