[osg-users] OSG documentation for osgAnimation

Hi all, at the moment I try to implement animations with OSG. I can`t find much documentation, e.g. how to use osgAnimation::Vec3CubicBezierSampler to define an animation path. There are examples and recipes in the 3 books. OSG is a great project and I really enjoy using it but I come often to
