hi all
I have a little probleme,
I have two node who represent two differents things,
and I would like to render one, and afer pushing a touch, changing on
other
something like that
//init
osg::Group* root = new osg::Group();
osg::Group* root2 = new osg::Group();
viewer.setSceneData( root );
// after a action
viewer.setSceneData( root2 );
// after a other action
viewer.setSceneData( root );
I trying that, but that doesn't work. (root 2 is accepted but core
dumped just after)
is it possible to do that??
Others have told you the "better way" to do this but in case you were
curious why it crashes the way you've done it, I'm pretty sure it's
because you aren't using ref_ptr's. Once you set root2 then root is
removed from the scene and the reference count goes to zero. This means
it is deleted.
Something like:
osg::ref_ptr<osg::Group> root = new osg::Group();
osg::ref_ptr<osg::Group> root2 = new osg::Group();
...would have made the rest work since you would then be holding your
own counted reference.

other thing
I dunno if it's normal but

there are no getSceneData or my viewer is a osg::Producer
thanks a+++
