The RT3 Extension is an off-the-shelf solution for displaying and analyzing live and simulated data feeds in STK and AGI Viewer. You can enhance the RT3 Extension by developing RT3 plugins using the RT3 object model.
The RT3 object model enables you to tailor the RT3 Extension to meet unique requirements, such as including custom data feed interfaces not available from AGI, proprietary data processing such as track correlation, and actions that are triggered by data events.
RT3 plugins may be written in any Microsoft Component Object Model (COM) compliant language, including C++, C#, and Visual Basic .NET. Once written, no additional licensing is required to use these plugins with the RT3 Extension.
