Index of GEOM/GEOM

This directory contains all the geometry  classes.

Several documents describing these classes are listed below:

• The main geometry class is documented in class TGeoManager.
• The Chapter about the TGeo classes in the Users Guide
• Presentation at ROOT 2002
• Presentation/article at CHEP'03
• Presentation at ROOT 2004
• Presentation at ROOT 2005
• Presentation at ROOT 2007

See also the use of the geometry classes in AliROOT package of ALICE.
