osg::PagedLOD::PagedLOD | ( | ) |
Copy constructor using CopyOp to manage deep vs shallow copy.
virtual osg::PagedLOD::~PagedLOD | ( | ) | [protected, virtual] |
virtual bool osg::PagedLOD::addChild | ( | Node * | child | ) | [virtual] |
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.

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.

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.

) | [virtual] |
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.

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.
