Detailed Description

Provide a basic sim engine to use in an example showing how to embed a sim engine into a driver that runs in a single thread.

Provide an example sim engine to use in an example showing how to embed a sim engine into a driver that runs in a separate thread.

The vast majority of this code is identical to the DtExampleSimEngine code in the exampleThreadedDriver example. Comparing the two is worthwhile. It creates an aircraft, with a HAT line and entity indicator, and updates it to fly in a circle and display the entity info widget when the mouse is over the entity indicator. The only significant difference between this code and the code in exampleThreadedDriver is that instead of using a connection, its using the display engine (DtDe) interface provided by the driver; and getting sim time from the DtDe instead of from the connection.

The vast majority of this code was extracted directly from DtExampleDriver. It creates an aircraft, with a HAT line and entity indicator, and updates it to fly in a circle and display the entity info widget when the mouse is over the entity indicator. The only significant difference between this code and the code extracted from exampleDriver is that instead of using the agent manager provided to the driver, its using the agent manager interface (sceneInterface()) provided by the connection; and getting sim time from the connection instead of from the DtDe. Note that we could have just grabbed clock time, but this demonstrates a way of moving this piece of data (sim time) from the driver to the connection.

Member Function Documentation

bool DtExampleSimEngine::init ( )

Initialize the simulation engine.

In this case, the entity facade, indicators, and hat line are created.

Returns: true if the initialization succeeds; false otherwise

bool DtExampleSimEngine::uninit ( )

Destroy what was created in init()

Returns: true if the initialization succeeds; false otherwise

bool DtExampleSimEngine::tick ( double simTime )

Perform updates param[in] simTime is he current simulation time.

Returns: true on success; false otherwise

void DtExampleSimEngine::slot_toggleLabelPinnedState ( const makVrv::DtSelectionManager::IdSet & selList )
