Well that will of course be diffrent depending on if I use Viewer or
CompositeViewer.
Never the less, I still think it is strange that I would be forced to tear down
the Viewer.run() functionallity into pieces just to add and remove objects to
the scenegraph during runtime. Which (at least to me) would be a pretty trivial
feature. But apparently not?

You can just call frame() in the while loop (if I'm right).
See what the viewer.run() do, you'll have a good overview of what to
use or not.

The viewer.sync() and viewer.update() seems to be deprecated.
And it seems a bit odd (at least for me) to just throw away the functionallity
contained in viewer.run().
I have searched the mail archive but I still can't find any
information how to properly add and remove content to the scenegraph during
runtime, whilst still using the viewer.run() method.

Hi,
I think the most secured way is to do it like that :
while( !viewer.done() )
{
viewer.sync();
viewer.update();
modify_scene_graph();
viewer.frame();
}
If I'm good, the callback allow safe graph
modifications, but only on node children... so depending on what you need, that
can be a solution too.
The subject have been discussed lots of time on the
mailing list, so check the archive and you will find some good informations.
Regards,
Vincent.

Hi!
I have my GameObject class that contains the
position of each dynamic game object in world coordinates. I also have my
GameObjectManager class that contains a vector of all game objects. This vector
is empty when the program starts, but populates with objects during runtime
(some objects is also removed during runtime).
I've searched the mail achieve but I can't find
any good example how to add or remove objects to the scenegraph during runtime.
I guess it has to be done in some form of callback. But which one? According to
http://www.mail-archive.com/[email protected]/msg00725.html it is a
bad idea to do it in a updateCallback.
Hopefully someone could give me an example or
at least point me at the right direction. Maybe there is an osg example I
should study in depth?
