Here is the call graph for this function:

Here is the caller graph for this function:

void Terrain::QuadTreeWorld::cacheCell ( View *  view, int  x, int  y  )

virtual

Load a terrain cell at maximum LOD and store it in the View for later use.

Note

Thread safe.

Reimplemented from Terrain::World.

Here is the call graph for this function:

View * Terrain::QuadTreeWorld::createView ( )

virtual

Create a View to use with preload feature. The caller is responsible for deleting the view.

Note

Thread safe.

Reimplemented from Terrain::World.

void Terrain::QuadTreeWorld::enable ( bool  enabled )

virtual

Reimplemented from Terrain::World.

Here is the call graph for this function:

void Terrain::QuadTreeWorld::ensureQuadTreeBuilt ( )

private

Here is the call graph for this function:

Here is the caller graph for this function:

void Terrain::QuadTreeWorld::preload ( View *  view, const osg::Vec3f &  eyePoint  )

virtual

Note

Thread safe, as long as you do not attempt to load into the same view from multiple threads.

Reimplemented from Terrain::World.

Here is the call graph for this function:

void Terrain::QuadTreeWorld::reportStats ( unsigned int  frameNumber, osg::Stats *  stats  )

virtual

Reimplemented from Terrain::World.

void Terrain::QuadTreeWorld::setDefaultViewer ( osg::Object *  obj )

virtual

Set the default viewer (usually a Camera), used as viewpoint for any viewers that don't use their own viewpoint.

Reimplemented from Terrain::World.
