I don't know of any tool to do this, it's very application specific functionality so not the type of thing you'll find in general purpose libraries. > Could someone give me a hint whats the best way to solve this? You'll need to implement a custom osgUtil::Intersector that is able to efficient pick points. The osgUtil::LineSegmentIntersector would be a good place to start when learning how to go about this - it just works on meshes though. For point intersection you'll probably be best to use a cylinder or cone representation for doing the point intersection testing. Also have a look at the osgpick example. Once you have the picked points then it's simple a case of simple vector maths i.e. (v1-v2).length().
