Hi Please note that you should ask a new question by starting a new email thread. This makes it easier for people to follow threads and maybe answer and even find answers them selves
When you would use a draw call back, or an update call back is totality dependent on what you're doing, are you updating or are you drawing etc. ( in a particular example it will be related to what that example is illustrating) I recommend that you have a read of Paul Martz quick Start guide if you have not done so already, it should tell you about the different traversals' that are in OSG and the basics of a scene graph, once you have a grapes of this then the example should make more sense and why different example use different parts of OSG etc See the www.osgbooks.com ____________________________________________________________________________ __ Gordon Tomlinson gor...@gordontomlinson.com IM: gordon3db...@3dscenegraph.com www.vis-sim.com www.gordontomlinson.com ____________________________________________________________________________ __ -----Original Message----- From: osg-users-boun...@lists.openscenegraph.org [mailto:osg-users-boun...@lists.openscenegraph.org] On Behalf Of Tim Allen Sent: Thursday, August 20, 2009 9:29 PM To: osg-users@lists.openscenegraph.org Subject: Re: [osg-users] apply() method??
