HI Mikhail,
So the problem is the the Rotate3DCommnd is being upcast to the base
class MotionCommand and then never the Constraint and DraggerCallbacks
only have their constrain(MotionCommand&)/recive(MotionCommand&)
methods called rather than the original subclass method i,e,
constain(Rotate3DCommand&) and recive(Rotate3DCommand&)?
Yes, it is.
If so then the problem looks to be one that would need tackling via a
double dispatch vistor pattern solution like used in
osg::Node::accept(NodeVisitor&)/osg::NodeVisitor::apply(Node&). I am
on the right track?
Yes, you are right.
Mikhail.
