This compatibility study examines potential interoperability between OpenSimulator, a free, server-based 3D virtual world simulator, and a set of DND/CF simulation tools. Interoperability is assessed in four areas: simulation operation, terrain models, 3D models, and human factors tools. Simulation technologies assessed for compatibility are the DIS and HLA simulation protocols, the Unity game engine, the VBS2 serious game, SmartMarine 3D and SmartPlant 3D CAD applications, the HumanCAD anthropomorphic articulation simulator, and the IPME task modelling and crew simulator. OpenSimulator does not use DIS or HLA, so it is not currently able to directly interface with any simulator that uses these industry standards. Terrain data compatibility is limited by the RAW format used by OpenSimulator. Unity is able to provide the required height-map portion of the terrain while VBS2 cannot produce a compatible terrain component directly. The set of DND/CF tools that use model-based assets can, in most cases, be converted to the COLLADA format which OpenSimulator is compatible with. HumanCAD also has the ability to export model formats that can be converted to COLLADA. IPME can communicate over TCP/IP connections and so an interface to OpenSimulator could be developed. Overall, OpenSimulator is compatible with the set of DND/CF tools examined in terms of its ability to re-use 3D model content originally developed for these tools. Some compatibility exists with respect to re-use of terra
