Visual Simulation and communication using X3D

XMSF: Extensible Modeling and Simulation Framework

Extensible Modeling and Simulation Framework (XMSF) is designed to support interoperability across the spectrum of models and simulations including constructive, virtual, and live modes as well as integrating legacy simulation frameworks and the increasingly important distance learning technologies. It uses X3D and XML Web Serivces to enable a new generation of distributed simulations.

X3D supports encoding of scenes using the Extensible Markup Language (XML), which ensures that files are self-validating and capable of reliable processing. Advanced X3D capabilities include geospatial referencing, humanoid animation, shared-state distribution using the IEEE Distributed Interactive Simulation (DIS) protocol, building prototypes, server-produced custom terrain, image overlay of photographic, cartographic or pseudocolor images, integrated physics for entity motion and sensor projection, a variety of user-interaction techniques, and scalable loading/unloading of interrelated scenes.

XMSF Precepts

  • Web-based technologies applied within an extensible framework will enable a new generation of modeling & simulation (M&S) applications to emerge, develop and interoperate.
  • Support for operational tactical systems is a missing but essential requirement for such M&S applications frameworks.
  • An extensible framework of Extensible Markup Language (XML)-based languages can provide a bridge between forthcoming M&S requirements and open/commercial web standards, while continuing to support existing M&S technologies.
  • Compatible and complementary technical approaches are now possible for model definition, simulation execution, network-based education, network scalability, and 2D/3D graphics views.
  • Web approaches for technology, software tools, content production and broad use provides best business cases from an enterprise-wide (i.e. world wide) perspective.
