Detailed Description

Subclass of DtPageInVisitor which pages in only nodes that fall along a particular geometry.

Constructor & Destructor Documentation

DtGeometryPageInVisitor::DtGeometryPageInVisitor ( const DtTerrainPagingGeometryPtr geometry )

virtual bool DtGeometryPageInVisitor::requiresPageIn ( osg::Node & node )

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 from DtPageInVisitor.

DtTerrainPagingGeometryPtr DtGeometryPageInVisitor::myGeometry
