Version 3 (modified by martin, 6 years ago)    The new
osgUtil::IntersectionVisitor at related helper class provide a
new general purpose set of ways on computing intersections with
scenes, handling different types of intersectors, such as line
segments, planes and polytopes, as well as handling paged
databases automatically as well as using double precision maths
to enable handling of whole earth databases. The original
osgUtil::IntersectVisitor and osgUtil::PickVisitor could only
handle LineSegment intersection, and could not handle large
scale databases or paged databases.
