Constructor & Destructor Documentation

◆ PagedLOD() [1/2]

osg::PagedLOD::PagedLOD ( )

Default constructor The default constructor sets

  • the center mode to USER_DEFINED_CENTER and
  • enables the paging of external children.
    Warning
    The center mode setting of the default constructor differs from the setting of LOD's default constructor! Therefore, the PagedLOD and LOD nodes may show different behaviour with their default settings when using them with the same subgraph. This is a result of the differences in determining the node's center.
    Note
    Though the bounding spheres of both nodes with their default settings will not differ if they have same subgraph.
    See also
    LOD::setCenter, LOD::setRadius

◆ PagedLOD() [2/2]

osg::PagedLOD::PagedLOD ( const PagedLOD ,
const CopyOp copyop = CopyOp::SHALLOW_COPY 
)

Copy constructor using CopyOp to manage deep vs shallow copy.

inline

◆ addChild() [3/5]

virtual bool osg::PagedLOD::addChild ( Node child)
virtual

Add Node to Group. If node is not NULL then increment its reference count, add it to the child list and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. Otherwise return false. Scene nodes can't be added as child nodes.

Reimplemented from osg::LOD.

◆ addChild() [4/5]

osg::ref_ptr< osg::Referenced > & osg::PagedLOD::getDatabaseRequest ( unsigned int  childNo)
inline

Return the DatabaseRequest object used by the DatabasePager to keep track of file load requests being carried on behalf of the DatabasePager. Note, in normal OSG usage you should not set this value yourself, as this will be managed by the osgDB::DatabasePager.

◆ getDatabaseRequest() [2/2]

const osg::ref_ptr< osg::Referenced > & osg::PagedLOD::getDatabaseRequest ( unsigned int  childNo) const
