VBSFusion is the official application programming interface (API) for VBS and is available for purchase by military, government and academic customers. Commercial customers can purchase Fusion through a VBSDN subscription.

It gives you direct access to the VBS engine, allowing you to develop new applications or plug-ins which leverage the power, graphics and simulation engine of VBS. VBSFusion enables you to create a customized training experience for the end user. VBSFusion (from SimCentric Technologies) is ideal for integrating VBS with external hardware and software systems, enhancing fidelity of the simulation, providing augmented displays within the virtual environment, and enhancing the user experience. VBSFusion is the fastest, most powerful, and best supported tool for building on the VBS platform.

The VBSFusion API is a collection of C++ data and utility classes which can be used to load and manipulate the state of objects within the VBS simulation environment. VBSFusion provides direct access to the VBS engine. It provides an API which can be used to programmatically access and modify the VBS simulation and the objects within it, marking VBS as a true simulation platform. Designed in C++, VBS Fusion removes the requirement for developers to learn the VBS scripting language.

VBSFusion offers significant advantages over the VBS Application Scripting Interface (ASI).

  • Direct access to the VBS core resulting in significant performance improvements over the ASI Complete Object-Oriented programming framework, making it easier to build and maintain bug-free code
  • Built-in logging tools to make testing and debugging of code easier and more efficient
  • Rich set of functionality including support for heads up display (HUD) and the ability to draw overlays over the VBS display
  • Ability to link to external C++ libraries
  • Write-once, run anywhere - once a Fusion plug-in is written and packaged it can be run on any other VBS machine


VBSFusion features extensive documentation of header files and includes examples of plug-ins. Each initial VBSFusion license purchase requires one year of VBSFusion Software Upgrades and Support Plan.

Additional years of VBSFusion Software Upgrades and Support as well as Professional Services support are available for separate purchase.
