  The Persint program is designed for the three-dimensional representation of
objects and for the interfacing and access to a variety of independent
applications, in a fully interactive way. Facilities are provided for the
spatial navigation and the definition of the visualization properties, in order
to interactively set the viewing and viewed points, and to obtain the desired
perspective. In parallel, applications may be launched through the use of
dedicated interfaces, such as the interactive reconstruction and display of
physics events. Recent developments have focalized on the interfacing to the
XML ATLAS General Detector Description AGDD, making it a widely used tool for
XML developers. The graphics capabilities of this program were exploited in the
context of the ATLAS 2002 Muon Testbeam where it was used as an online event
display, integrated in the online software framework and participating in the
commissioning and debug of the detector system.
