osg::PagedLOD::PagedLOD ( )
osg::PagedLOD::PagedLOD ( const PagedLOD ,

Member Function Documentation

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.

Reimplemented from osg::LOD.

virtual bool osg::PagedLOD::addChild ( Node child,
float  min,
float  max 
)
virtual

Reimplemented from osg::LOD.

virtual bool osg::PagedLOD::addChild ( Node child,
float  min,
float  max,
const std::string &  filename,
float  priorityOffset = 0.0f,
float  priorityScale = 1.0f 
)
virtual
void osg::PagedLOD::expandPerRangeDataTo ( unsigned int  pos)
protected
osg::Referenced* osg::PagedLOD::getDatabaseOptions ( )
inline

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

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

Get the optional database osgDB::Options object used when loaded 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.

inline
unsigned osg::PagedLOD::getFrameNumber ( unsigned int  childNo) const
inline
unsigned int osg::PagedLOD::getFrameNumberOfLastTraversal ( ) const
inline

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

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.

osg::PagedLOD::META_Node ( osg  ,
PagedLOD   
)
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 loaded 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::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.
