OK I tried both of your solution and finally choose one. I chose the CullCallback because you can use it directly on a Node object while the DrawCallback is implented into the Drawable objects and in my case I have many Drawable into one Geode, moreover I created my own node type for this project that contains two distinct Geodes but one cannot be manipulated. Thank you so much for your help. OSG is a very powerful tool but hard to learn with its hundreds of classes and more subclasses ;) See Ya Adrien ------------------ Read this topic online here: http://forum.openscenegraph.org/viewtopic.php?p=9274#9274 _______________________________________________ osg-users mailing list osg-users@lists.openscenegraph.org http://lists.openscenegraph.org/listinfo.cgi/osg-users-openscenegraph.org
