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).

Hello,
I'm implementing a draw instanced optimized scene. This is for drawing a set of
polygons.
Previously I was creating a drawable for each polygon, but now I am using draw
instancing. With one drawable per polygon I can easily use osg intersectors for
computing scene intersections. But how can I perform scene intersections with
draw instanced objects and get, for instance, intersected instance IDs?
