[osg-users] Assign Vec3d to Node

[OpenSceneGraph Users]

Hi,

I'm creating objects that must fall by gravity. So I need to assign a 
Vec3d, representing speed, to each Node. Is there a proper way to do it? 
Maybe some variable inside the Node, Geode, ShapeDrawable, etc, or some 
function for this kind of variable assignment? Or must I create an array 
outside the OSG variables?

Thanks,
Rodrigo.
