[osg-users] Collided nodes in callback

[Julien Valentin]

So you fit my second assertion: you want to manage collision yourself...
One way to achieve that brute force is to use a NodeVisitor that collect all the node (applied in a update callback on the root of your scenegraph) and then do your collide test in your node callback.
But keep in mind the dirty way, broadphase collision detection is a feature inherent to the physics engine and not to the rendering engine...
