Interactive Mode provides a highly configurable interface for querying simulations. Users supply arbitrary rays to be traced and then extract the result. The output can be set to human-friendly plaintext, parser-friendly XML, or high-performance binary.
During the interactive simulation, the specific information to be pulled is specified through a Collector Configuration File. This is a simple XML file for which a a Document Type Definition (DTD) is available. Details about this file are in the Interactive Mode How-To.
