Hi Gordon, Thanks for your reply, I'm going to give that a go.
First check - see if its in the bounding sphere of the PAT Second check - go for the bounding boxes of the drawables. I guess I'll need to inverse transform my point by the PAT's matrix first? Anyway good to know it's not too difficult, Thank you, Andrew ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=15633#15633 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
