= external Link =

The extLink module is the visual systems connection to the rest of the simulator, especially to the simulation host. It receives the values from the simulation host which control certain visual system modules or represent the visualized objects in the the visual system. Additionally it sends all return values back from the visual objects to the external simulation system

== Implementation ==

extLink is a abstract base class which defines the interface to osgVisual each ectLink implementation must provide. See [wiki:visual_extLinkDummy extLink Dummy] and [wiki:visual_extLinkVCL extLink VCL] for certain implementations.
