TVirtualMC Class Referenceabstract

Abstract Monte Carlo interface.

Virtual MC provides a virtual interface to Monte Carlo. It enables the user to build a virtual Monte Carlo application independent of any actual underlying Monte Carlo implementation itself.

A user will have to implement a class derived from the abstract Monte Carlo application class, and provide functions like ConstructGeometry(), BeginEvent(), FinishEvent(), ... . The concrete Monte Carlo (Geant3, Geant4) is selected at run time - when processing a ROOT macro where the concrete Monte Carlo is instantiated.
