The code you send seems to be correct, you just apply the visitor on
GROUP and NODE typed OSG objects. But as I know animation paths can
only be attached to
osg::PositionAttitudeTransform
and
osg::MatrixTransform
so you have to apply the visitor on these type of objects...
Finally make the following dynamic casts to see if there is an
animationpath attached on these nodes.
p_UCB = dynamic_cast<osg::NodeCallback*>(NodeFromVisitor->getUpdateCallback());
p_APCB = dynamic_cast<osg::AnimationPathCallback*>(p_UCB);
p_AP = dynamic_cast<osg::AnimationPath *>(p_APCB->getAnimationPath());
In each step test for NULL. at last step p_AP will hold the animation
path if exists...
