Description

The current major detector simulation programs, i.e. GEANT3, GEANT4 and FLUKA have largely incompatible environments. This forces the physicists willing to make comparisons between the different transport Monte Carlos to develop entirely different programs. Moreover, migration from one program to the other is usually very expensive, in manpower and time, for an experiment offline environment, as it implies substantial changes in the simulation code. To solve this problem, the ALICE Offline project has developed a virtual interface to these three programs allowing their seamless use without any change in the framework, the geometry description or the scoring code. Moreover a new geometrical modeller has been developed in collaboration with the ROOT team, and successfully interfaced to the three programs. This allows the use of one description of the geometry, which can be used also during reconstruction and visualisation. The talk will describe the present status and future plans for the Virtual Monte Carlo. It will also present the capabilities and performance of the geometrical modeller.
