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.
