 For example, a user might start in a corporation's virtual lecture hall and walk through a portal to a university's submarine simulation.The lecture hall might have modules installed for virtual microphones, slide show presentations, and business intelligence analysis, while the submarine simulation may include a fluid dynamics module, a working submarine console, and integration with telemetry data from a real submarine.While much of the code to run the Open Wonderland worlds is shared, the specialized 2D and 3D programs that run in these worlds are not shared.
