Hi Tomas, This is a software design question, not really an OpenSceneGraph one. I'd recommend reading articles/books on game/object oriented design. The design of your classes will depend on your application requirements, taking into account money/time/etc. constraints.
I'd recommend that your design abstract out rendering such that your OSG code is in separate rendering components. We do this in our visualization applications to allow us to switch renderers. We do this using a component based object management design (see http://cowboyprogramming.com/2007/01/05/evolve-your-heirachy/) and it has worked out really well. Good luck, - Donny On Wed, Apr 1, 2009 at 5:32 AM, Tomas Lundberg <tomas...@gmail.com> wrote: > Hi, > > I have done some small test projects for fun in OSG, without really > learning it correctly.
