I think the problem might be the pHudRootNode->getParentalNodePaths()[0]
What this will do is traverse only the node getParentalNodePaths()[0] and is direct SceneGraph descendants As far as I know it will not traverse paths only the first node which may or may not be a node your after Perhaps you want pHudRootNode->getParent() or just pHudRootNode __________________________________________________________ Gordon Tomlinson [EMAIL PROTECTED] IM: [EMAIL PROTECTED] www.vis-sim.com www.gordontomlinson.com __________________________________________________________ -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Riccardo Corsi Sent: Wednesday, August 13, 2008 7:30 PM To: OpenSceneGraph Users Subject: Re: [osg-users] pick on specific subgraph / nodepath Hi Gordon, I know the nodemask is an often suggested solution, but what I don't like about it is that it forces me to touch also other nodes/subgraphs I'm not interested in, that I would ignore, while I must go and set a mask on them. Instead, when I know a priori the small subgraph I want to pick on (one representing a manipulator, for instance) I would consider more straightforward and less "polluting" to pick on a single nodepath, instead of excluding all of the others via nodemask. Does this make sense? Or there's a better use of nodemasks I'm not aware of??

Unfortunately it didn't work as aspected, and I don't know where I'm wrong. I modified the osgpick example (attached) to pick, for instance, only the rectangles in the HUD. What I do is: - store the root of the HUD in a pHudRootNode - pick with the funtion viewer->computeIntersections(ea.getX(), ea.getY(), pHudRootNode->getParentalNodePaths()[0], intersections) but I don't get any result. I've also tried to limit the nodepath to the view's SceneData, like this: pHudRootNode->getParentalNodePaths(viewer->getSceneData())[0] but it doesn't work either. Where am I wrong? Thank you!
