[osg-users] Draw Instanced intersections

[tianzjyh]

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?
