This might be more of a general C++ question but I'm having the
following problem:
I have a MatrixTransform derived class called Entity
Ie. sgm::Entity : public MatrixTransform.
I use it to define a couple extra data values that I would like to store
and overload some of the inherited functions. I added a node with
geometry to the Entity via Entity::AddChild(node);
It works fine and behaves like I would expect when I add it to the scene
graph but when I use picking to pull the node out of the scene graph and
follow the path to its parental Entity I am unable to call dynamic_cast
on it and get a non-NULL result.
If I use the same procedure and instead try a dynamic cast to an
osg::MatrixTransform it works just fine.
What happens if you use a static_cast to Entity? Assuming you pick the
right geometry of course (the one hanging from you Entity instance).
