EXTON, Pa., Oct. 21, 2004 -- Analytical Graphics, Inc. (AGI) announces today the introduction of AGI Viewer - a free, easy-to-use software tool that enables people of any technical level to view, interact with, or embed the comprehensive aerospace and national security analyses generated by AGI's STK software suite.

AGI Viewer users can utilize 4-D scenes encrypted within Viewer Data Format (VDF) files. These files are created with STK/Author, a new software module released in STK Version 6.1. STK/Author allows STK v6.1 users to save scenarios from any of their licensed STK products as VDF files, and share them with anyone - both STK users and non-users alike - who has AGI Viewer. In addition to controlled playback of these STK scenes, AGI Viewer users also can zoom and pan; create high-resolution screen snaps and movies; or embed this dynamic output in PowerPoint(R), Microsoft(R) Word, or HTML.

"AGI Viewer will certainly extend the value of STK to a much broader audience," says Francesco Linsalata, AGI's chief operating officer. "People from any technical background can now add a whole new dimension of communication to their proposals, presentations, or deliverables by incorporating AGI Viewer's dynamic 4-D scenes."

AGI Viewer is available as a free download or CD request at http://www.agi.com/viewer. More information on how STK users can create VDF files for AGI Viewer users can be found at http://www.agi.com/author.
