Constructor & Destructor Documentation

osg::PagedLOD::PagedLOD

(

)

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

Copy constructor using CopyOp to manage deep vs shallow copy.

Member Function Documentation

virtual bool osg::PagedLOD::addChild	(	Node *	child,
		float	min,
		float	max,
		const std::string &	filename,
		float	priorityOffset = 0.0f,
		float	priorityScale = 1.0f
	)			[virtual]

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

Reimplemented from osg::LOD.

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.

void osg::PagedLOD::expandPerRangeDataTo

(

unsigned int

pos

)

[protected]

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

(

)

const [inline]

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

const std::string& osg::PagedLOD::getFileName

(

unsigned int

childNo

)

const [inline]

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.

unsigned int osg::PagedLOD::getNumFileNames

(

)

const [inline]

unsigned int osg::PagedLOD::getNumPriorityOffsets

(

)

const [inline]

unsigned int osg::PagedLOD::getNumPriorityScales

(

)

const [inline]

unsigned int osg::PagedLOD::getNumTimeStamps

const [inline]

float osg::PagedLOD::getPriorityOffset

(

)

const [inline]

float osg::PagedLOD::getPriorityScale

const [inline]

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,
		NodeList &	removedChildren
	)			[virtual]

Remove the children from the PagedLOD which haven't been visited since specified expiry time. 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::setDatabasePath

(

const std::string &

path

)

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

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

void osg::PagedLOD::setFrameNumberOfLastTraversal

(

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 &

nv

)

[virtual]

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

Reimplemented from osg::LOD.
