Hi Bruno,
There is simply no geometry in the scenegraph to intersect (or strictly
speaking there is only one drawable)
Instancing takes away the load from the CPU to the GPU,which on the
OSG-side means to put the instanced geometries into one drawable
containing the instancing information.
Hi, Oliveira,
there maybe many reasons that why no intersection. I cannot give you advise
without more information. u can check about examples within OSG source code,
e.g. "osgintersection".

Hi TianZJ, Thanks for the quick answer.
I checked the intersector, but intersector->getIntersections() returns no
intersections at all.

Hi, Oliveira,
You can check the intersections of your intersector(e.g.
LineSegmentIntersector::Intersection), and you will find they contain an
"osg::NodePath", which means the whole path of the node(e.g. matrix transform
nodes upon the drawable instance).
