WebLVC

Simple applications and interfaces to control complex simulations

WebLVC Suite is both a server and a set of web-based applications, that simplify and expand the reach of live, virtual, and constructive simulations.

Users can observe, control, and participate in their simulation from any computer or mobile device with a compatible web browser and access to their simulation network. Engineers can setup and monitor simulations from their desks. Program managers can bring the simulation into staff meetings. Trainees can gain situational awareness while carrying out missions in the field. Instructors and observers can gain insight into live exercises on the range. Analysts can replay and study the results without going to the simulation lab. Business development teams can present operational capabilities and concepts at the customer’s site.

Even if users work in a secure lab on a secure network, they can take advantage of web-based applications by hosting servers inside their firewall.

A range of web apps are included in WebLVC Suite;

The higher-level applications provide a broad capability that can be configured for use in scenarios.

  • The Commander app displays simulation entities as 2D icons on a map. Users can touch the entities to inspect the state of the entities or to give them new simulation tasks.
  • The Instructor app is a simple interface that allows the instructor to inject faults into the scenario and to change the simulated environmental conditions and time of day.
  • The VR-Vantage Viewer lets users see in 3D what’s going on inside the simulation scenario.
  • The VR-Vantage Controller lets users move around the eyepoint used by the VR-Vantage Viewer.
  • With the Presenter app, save views of events that happen during a scenario and use them to make a time synchronized presentation of the activity.

Lower-level applications help users master the fundamentals of web app development, via an infrastructure designed to save time and effort.

  • The Diagnostic Message Inspector listens to the WebLVC messages coming from the WebLVC Server and displays their content as text on the browser.
  • The Simple Listener listens to the WebLVC connection and displays each entity as a symbol on an OpenLayers map.
  • VR-Forces Control presents a simple control to Play/Pause/Rewind the scenario running in VR-Forces.
  • Detonate Now shows users how to add a detonation interaction to a simulation network using WebLVC.
  • Simple Publisher shows users how to use WebLVC to publish an entity that is simulated in the browser.
  • Close Air Support (CAS) allows users to call for close air support using a standard 9-line interface. The simulation is performed by VR-Forces.
  • WebLVC Suite also comes with several examples of third party javascript based graphics and terrain data API’s.

WebLVC Server:

  • The WebLVC Server is the linchpin that connects web-based simulation federates to DIS/HLA federations using the WebLVC protocol. The Server, implements the server side of the WebLVC protocol so users web-based simulation federates can participate in a distributed simulation.
