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

virtual

Add Node to Group.

If node is not NULL and is not contained in Group 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.

void osg::PagedLOD::expandPerRangeDataTo ( unsigned int pos )

protected

osg::Referenced* osg::PagedLOD::getDatabaseOptions ( )

inline

Get the optional database osgDB::Options object used when reading children.

const osg::Referenced* osg::PagedLOD::getDatabaseOptions ( ) const

inline

Get the optional database osgDB::Options object used when reading children.

const std::string& osg::PagedLOD::getDatabasePath ( ) const

inline

Get the database path used to prepend to children's filenames.

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.

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

inline

Return the const DatabaseRequest object.

unsigned int osg::PagedLOD::getFrameNumberOfLastTraversal ( ) const

inline

Get the frame number of the last time that this PageLOD node was traversed.

inline

double osg::PagedLOD::getMinimumExpiryTime ( unsigned int childNo ) const

inline

unsigned int osg::PagedLOD::getNumChildrenThatCannotBeExpired ( ) const

inline

Get the number of children that the PagedLOD must keep around, even if they are older than their expiry time.

virtual bool osg::PagedLOD::removeChildren	(	unsigned int	pos,
		unsigned int	numChildrenToRemove = `1`
	)

virtual

Remove children from Group.

Note, must be override by subclasses of Group which add per child attributes.

Reimplemented from osg::LOD.

virtual bool osg::PagedLOD::removeExpiredChildren	(	double	expiryTime,
		unsigned int	expiryFrame,
		NodeList &	removedChildren
	)

virtual

Remove the children from the PagedLOD which haven't been visited since specified expiry time and expiry frame number.

The removed children are added to the removeChildren list passed into the method, this allows the children to be deleted later at the caller's discretion. Return true if children are removed, false otherwise.

void osg::PagedLOD::setDatabaseOptions ( osg::Referenced * options )

inline

Set the optional database osgDB::Options object to use when reading children.

void osg::PagedLOD::setDatabasePath ( const std::string & path )

Set the database path to prepend to children's filenames.

void osg::PagedLOD::setDisableExternalChildrenPaging ( bool flag )

inline

Set wether you want to disable the paging in of external nodes.

void osg::PagedLOD::setFileName	(	unsigned int	childNo,
		const std::string &	filename
	)

inline

void osg::PagedLOD::setFrameNumber	(	unsigned int	childNo,
		unsigned int	frameNumber
	)

inline

void osg::PagedLOD::setFrameNumberOfLastTraversal ( unsigned int frameNumber )

inline

Set the frame number of the last time that this PageLOD node was traversed.

Note, this frame number is automatically set by the traverse() method for all traversals (update, cull etc.).

void osg::PagedLOD::setMinimumExpiryFrames	(	unsigned int	childNo,
		unsigned int	minFrames
	)

inline

Sets the minimum number of frames that must be rendered without a child being traversed before it can be expired.

void osg::PagedLOD::setMinimumExpiryTime	(	unsigned int	childNo,
		double	minTime
	)

inline

Sets the minimum amount of time, in seconds, that must pass without a child being traversed before it can be expired.

void osg::PagedLOD::setNumChildrenThatCannotBeExpired ( unsigned int num )

inline

Set the number of children that the PagedLOD must keep around, even if they are older than their expiry time.

void osg::PagedLOD::setPriorityOffset	(	unsigned int	childNo,
		float	priorityOffset
	)

inline

void osg::PagedLOD::setPriorityScale	(	unsigned int	childNo,
		float	priorityScale
	)

inline

void osg::PagedLOD::setTimeStamp	(	unsigned int	childNo,
		double	timeStamp
	)

inline

virtual void osg::PagedLOD::traverse ( NodeVisitor & )

virtual

Traverse downwards : calls children's accept method with NodeVisitor.

Reimplemented from osg::LOD.
