void osgUtil::IntersectVisitor::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.
