To implement different types of intersection techniques, one implements custom versions of the osgUtil::Intersector, and then pass the constructed intersector to the IntersectionVisitor.

| virtual void osgUtil::IntersectionVisitor::reset | ( | ) | [virtual] |
Method to call to reset visitor.
Useful if your visitor accumulates state during a traversal, and you plan to reuse the visitor. To flush that state for the next traversal: call reset() prior to each traversal.
Reimplemented from osg::NodeVisitor.

Set the intersector that will be used to intersect with the scene, and to store any hits that occur.
| Intersector* osgUtil::IntersectionVisitor::getIntersector | ( | ) | [inline] |
Get the intersector that will be used to intersect with the scene, and to store any hits that occur.
| const Intersector* osgUtil::IntersectionVisitor::getIntersector | ( | ) | const [inline] |
Get the const intersector that will be used to intersect with the scene, and to store any hits that occur.
| void osgUtil::IntersectionVisitor::setReadCallback | ( | ReadCallback * | rc | ) | [inline] |
Set the read callback.
| ReadCallback* osgUtil::IntersectionVisitor::getReadCallback | ( | ) | [inline] |
Get the read callback.
| const ReadCallback* osgUtil::IntersectionVisitor::getReadCallback | ( | ) | const [inline] |
Get the const read callback.
