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.

virtual osg::PagedLOD::~PagedLOD (   )  [inline, protected, virtual]

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.

virtual void osg::PagedLOD::childInserted (  unsigned int  pos  )  [protected, virtual]

Reimplemented from osg::LOD.

virtual void osg::PagedLOD::childRemoved (  unsigned int  pos, unsigned int  numChildrenToRemove )  [protected, virtual]

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 (  unsigned int  childNo  )  const [inline]

float osg::PagedLOD::getPriorityScale (  unsigned int  childNo  )  const [inline]

double osg::PagedLOD::getTimeStamp (  unsigned int  childNo  )  const [inline]

osg::PagedLOD::META_Node (  osg  , PagedLOD  )

virtual void osg::PagedLOD::rangeInserted (  unsigned int  pos  )  [protected, virtual]

Reimplemented from osg::LOD.

virtual void osg::PagedLOD::rangeRemoved (  unsigned int  pos, unsigned int  numChildrenToRemove )  [protected, virtual]

Reimplemented from osg::LOD.

virtual bool osg::PagedLOD::removeChild (  Node *  child  )  [virtual]

Remove Node from Group. If Node is contained in Group then remove it from the child list, decrement its reference count, and dirty the bounding sphere to force it to recompute on next getBound() and return true for success. If Node is not found then return false and do not change the reference count of the Node. 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.
