Hi all,
I'm trying to add more than one nodeCallback on a single node. It would be
very useful for my application.
First way :
In the archive, I founded this :
http://lists.openscenegraph.org/htdig.cgi/osg-users-openscenegraph.org/2007-October/003905.html
I didn't saw it in OSG sources, so I suppose it hasn't been implemented ?
Other way to do it :
In the explanation, I found the following code :
if (node->getUpdateCallback())
> node->getUpdateCallback()->addNestedCallback(callback);
> else
> node->setUpdateCallback(callback);
>
What is the difference between a "nested" callback and a normal nodeCallback
?
How many nested callback is it possible to add ?
Thanks a lot,
Regards,
Vincent.
