DtPageInVisitor Class Reference

OSG Visitor class which pages the highest level of detail of paged LOD nodes in. This is a base class, intended to be overridden. This base class will cause paging in of every paged LOD node. Subclasses may be more selective by overriding requiresPageIn().

virtual void DtPageInVisitor::apply ( osg::PagedLOD &  node )

Reimplemented in PagedNode2CollectTrianglesVisitor, and PagedNode2LoadDataVisitor.

inline

virtual bool DtPageInVisitor::requiresPageIn ( const osg::BoundingSphere &  )

protectedvirtual

Returns

True if this node should be paged in. This is overridden in subclasses, depending on how the paging is being implemented. Default implementation returns true, which pages in the entire database.

Reimplemented in DtGeometryPageInVisitor.

virtual osg::Node* DtPageInVisitor::getNode ( const std::string &  filepath, const osgDB::Options *  , bool &  valid  )

protectedvirtual

Produce a node from a filepath. Default calls osgDB::readNodeFile. If a node cannot be created then a dummy node (an empty group) will be returned and the valid parameter will be set to false (true if otherwise)

virtual bool DtPageInVisitor::shouldExit ( ) const

protectedvirtual

Should the traversal quit. Used to bail out when exiting.
