DtOsgEarthCache manages the caching of osgEarth tiles. It supports caching using the osgEarth API or flying a camera to the interseted area to invoke the data pager to generate cache.

Member Function Documentation

virtual void makVrv::DtOsgEarthCache::setMapNode ( osgEarth::MapNode * mapNode )

virtual

Setw the MapNode that forms the root of an osgEarth map.

virtual void makVrv::DtOsgEarthCache::setLowestLod ( int lowestLod )

virtual

Sets the lowest lod to cache, only the tiles with a higher lod will be cached.

The lowest lod to generate cache.

virtual int makVrv::DtOsgEarthCache::lowestLod ( ) const

virtual

Gets the lowest lod to cache, only the tiles with a higher lod will be cached.

The lowest lod to generate cache.

virtual void makVrv::DtOsgEarthCache::setHighestLod ( int highestLod )

virtual

Sets the highest lod to cache, only the tiles with a higher lod will be cached.

The highest lod to generate cache.

virtual int makVrv::DtOsgEarthCache::highestLod ( ) const

virtual

Gets the highest lod to cache, only the tiles with a higher lod will be cached.

The highest lod to generate cache.

virtual void makVrv::DtOsgEarthCache::setCacheMethod ( Method method )

virtual

Sets the cache method to generate the cache.

virtual Method makVrv::DtOsgEarthCache::cacheMethod ( ) const

virtual

Gets the cache method to generate the cache.

virtual void makVrv::DtOsgEarthCache::setBound ( const osgEarth::Bounds & bound )

virtual

Sets the Bound of the cache area.

virtual osgEarth::Bounds makVrv::DtOsgEarthCache::bound ( ) const

virtual

Gets the Bound of the cache area.

virtual void makVrv::DtOsgEarthCache::setCacheImageLayers ( bool val )

virtual

Sets whether skip the caching of the image layers.

Parameters

skip	if true, it will skip caching image layers.

virtual void makVrv::DtOsgEarthCache::setCacheElevationLayers ( bool val )

virtual

Sets whether cache elevation layers.

virtual void makVrv::DtOsgEarthCache::initializeChannel ( DtChannel * channel )

virtual

Sets the observer object we used to fly the eyepoint, it's the observer of the channel's master scene camera by default. Sets the databasePager that handles the paging of the tiles. It's used to determine if we have finish paged everything in this tile before we move to next tile. This is only used in FLY_VIEWPOINT_CACHE method.

virtual void makVrv::DtOsgEarthCache::reset ( )

virtual

Resets the data from the previous operation.

virtual void makVrv::DtOsgEarthCache::startCache ( )

virtual

Starts the cache.

virtual void makVrv::DtOsgEarthCache::apiCache ( )

virtual

Cache the terrain using the osgEarth api.

virtual void makVrv::DtOsgEarthCache::viewPointCache ( )

virtual

Cache the terrain by moving the view point.

virtual void makVrv::DtOsgEarthCache::cancelCache ( )

virtual

Forces the cache to cancel.

virtual bool makVrv::DtOsgEarthCache::isCanceled ( )

virtual

Gets whether the cache is canceled.

Returns: return true if cache is canceled,otherwise return false

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

private
