TGeoMedium Class Reference

Media are used to store properties related to tracking and which are useful only when using geometry with a particle transport MC package (via VMC).

This is a wrapper class to G4OpticalSurface.

One may define several tracking media for a given material. The media ID are user defined values that are not used by the geometry package. In case geometry is used via VMC (in GEANT) these numbers are overwritten, so one can only rely on these values after gMC->FinishGeometry() is called. The media parameters are inspired from GEANT3 and the values defined make sense in context of GEANT (3 but also 4) or FLUKA interfaces.
