Detailed Description

IntersectionVisitor is used to testing for intersections with the scene, traversing the scene using generic osgUtil::Intersector's to test against the scene. To implement different types of intersection techniques, one implements custom versions of the osgUtil::Intersector, and then pass the constructed intersector to the IntersectionVisitor.
