Hi Robert, maybe I didn't explain correctly.
I have this graph :
/ Geodes
/AuxiliarData \
/ \ Geodes
Root/
\
\ / Geodes
RealSceneData/
\ Geodes
I want to get Interesections only for the geometry hanging from the
RealSceneData node.
I was doing this using osgProducer::computeIntersections, but now I
can't with osgViewer
any idea?

You use the NodePath methods, the node path is the path to the node of
interest. The OSG supports children with multiple parents, so passing
in just the node itself can produce multiple hits.
You can get the node paths from a node using node::getParentalNodePaths()

Hi all,
I've started using osgViewer, and to get intersections
I've found these functions:
bool View::computeIntersections(float x,float y,
osgUtil::LineSegmentIntersector::Intersections&
intersections,osg::Node::NodeMask traversalMask)
bool View::computeIntersections(float x,float y, osg::NodePath&
nodePath, osgUtil::LineSegmentIntersector::Intersections&
intersections,osg::Node::NodeMask traversalMask)
But i need to get intersections from a given node from the scene, not
the entire graph, as I used to do with osgProducer::Viewer :
bool osgProducer::computeIntersections (float x, float y, osg::Node
*node, osgUtil::IntersectVisitor::HitList &hits, osg::Node::NodeMask
traversalMask)
Is there is any way to use a similar function using
osgViewer::View ?
Thanks.
