Overview

With the VR-Link networking toolkit, you can quickly and easily network simulators and virtual reality applications using either the U.S. DoD’s High Level Architecture (HLA) or the Distributed Interactive Simulation (DIS) protocol. VR-Link’s easy-to-use programmer’s interface and powerful code generation tools reduce the risk, cost, and time necessary to maintain existing simulations or develop new ones. VR-Link simulations can be fully HLA compliant while maintaining the DIS compatibility vital to legacy projects. An add-on module for TENA support is available.

VR-Link saves development dollers by providing a singe documented API that abstracts away the details of DIS or HLA networking.VR-Link's top-level protocol-independed API is used to set the current state of localy simulated entities and objects. 

Application Fields

▪  Distributed in-the-loop simulation system

▪  Virtual Reality Simulation Environment
 

Features

▪  Rich set of vector and matrix manipulation functions
▪  Platform-independent interface to system clock
▪  Support for discrete simulation time
▪  Coordinate Conversions:Geocentric, Geodetic(Lat/Long/Alt), UTM, Topographic
▪  User-defined DIS PUDs or HLA objects and interactions are easily added
▪  Default functionality overridden through subclassing

The VR-Link Code Generator reads any HLA FOM, and automatically generates VR-Link extensions for that FOM. The tool produces fully-formed C++ source and header files, along with the Microsoft Visual C++ solution files and the UNIX® Makefiles required to compile them into a VR-Link extension library. The generated classes are ready to use for publishing and tracking new classes of HLA objects, and for sending and receiving custom interactions. The VR-Link Code Generator works with both HLA-1.3-style OMT files and IEEE-1516-style XML-based FOMs.
