Member Function Documentation

virtual void DtPreloadCommandManager::tick ( )

virtual

While myGeometryQueue is not empty, call pageInData on the active page tracker.

virtual void DtPreloadCommandManager::addPreloadGeometry ( const DtTerrainPagingGeometryList &  geometryList, unsigned int  intersectId  )

virtual

Add goemetry to be paged in.

Parameters

geometryList	The geometry to add
intersectId	The intersectId to use for the paged in geometry.

virtual void DtPreloadCommandManager::startPreloadCommandThread ( )

virtual

Starts the execution of a separate thread that will handle terrain paging.

void DtPreloadCommandManager::stopPreloadCommandThread

(

)

Stop the external thread.

Blocks until the thread has been shut down. Non-virtual becuase it is called by the destructor.

bool DtPreloadCommandManager::threadShouldExit

(

)

const

Called by the thread.

Returns true if the thread should exit, as indicated myThreadShutdown

static void DtPreloadCommandManager::threadMain ( DtPreloadCommandManager *  commandManager )
