Atlantis is an event display for the ATLAS experiment at CERN's Large Hadron Collider.

The primary goals of the program are the visual investigation and the understanding of the physics of complete events. Secondary goals are to help develop reconstruction and analysis algorithms, to facilitate debugging during commisioning and to provided a tool for creating pictures and animations for publications, presentations and exhibitions.

Atlantis is based on the ALEPH event display DALI.

Atlantis is written entirely in Java. JiveXML (event converter) is a C++ interface between Atlantis and the Athena ATLAS offline SW framework.

Atlantis event visualisation is a fast, interactive and intuitive application allowing study of complete ATLAS events.
