Detailed Description

This class is responsible for the actual processing of CIGI data.

This holds the entity visualizer, the CIGI settings, the signal processor, etc. This class be be run in a separate thread from the CIGI driver. This is the actual 'simulation' thread.

virtual bool makVrv::DtCigiConnection::disconnect ( )

virtual

Disconnects from the host.

virtual void makVrv::DtCigiConnection::setConnectionInitializer ( const DtCigiConnectionInitializer &  init )

virtual

Set the initialization settings.

virtual

Sets the coordinate system. Called by the driver in a thread-safe manner.

Warning

This function will always return 0 when the simulation is in the process of destroying all instances, this allows some what save access to findInstance in object destructors.
