Hi Robert, Thanks for the explanations. Can it be considerer as two callback at the same level ? or the nodecallback and the nested nodecallback are diferents ?

( http://lists.openscenegraph.org/htdig.cgi/osg-users-openscenegraph.org/2007-October/003905.html ) thanks, Regards, Vincent. 2008/7/22 Robert Osfield <[EMAIL PROTECTED]>: > HI Vinvent, > > A nested callback, is simply a NodeCallback which has another > NodeCallback nested in side it.
