root->removeChild(pyramidGeode) ;-) The OSG uses ref counting of all scene graph objects, a consequence is that most destructors are private to stop you from deleting objects inappropriately. Using ref_ptr<>'s is the way to retain robust pointers to scene graph objects, and this smart pointer will manage the reference counting and automatic deletion for you.
