Member Function Documentation

virtual void makVrv::DtOsgEarthCacheTileHandler::setMinRangeFactor ( float  min_range_factor )

virtual

Sets the min_range_factor that determines how close you need to be to a terrain tile for it to display.The value is the ratio of a tile's extent to its visible range. For example, if a tile has a 10km radius, and the factor = 7(default), then the tile will become visible at a range of about 70km.

virtual void makVrv::DtOsgEarthCacheTileHandler::setObserverObject ( DtObserverObject *  observer )

virtual

Sets the observer object we used to fly the eyepoint, it's the observer of the channel's master scene camera by default.

virtual bool makVrv::DtOsgEarthCacheTileHandler::handleTile ( const osgEarth::TileKey &  key, const osgEarth::TileVisitor &  tv  )

virtual

osgEarth::TileHandler Override

virtual bool makVrv::DtOsgEarthCacheTileHandler::hasData ( const osgEarth::TileKey &  key ) const

virtual

osgEarth::TileHandler Override Always return true since we don't want to miss a potential tile that may have any kind of data.

virtual void makVrv::DtOsgEarthCacheTileHandler::setDatabasePager ( osgDB::DatabasePager *  databasePager )

virtual

Sets the databasePager of the current scene, we use it to determine if we have finished paging everything in this tile before before we move to next tile.

virtual void makVrv::DtOsgEarthCacheTileHandler::reset ( )

virtual

Resets flag.

virtual void makVrv::DtOsgEarthCacheTileHandler::moveCameraToTile ( const osgEarth::TileKey &  key )

protectedvirtual

Move the camera to a position that has the tile with given key visible in the frustum.

DtOsgEarthCacheTileHandler& makVrv::DtOsgEarthCacheTileHandler::operator= ( const DtOsgEarthCacheTileHandler &  )

private

Assignment Operator not implemented – Copy not allowed.
