Requests the current value of the visibility flag for the node motion object. The visibility flag determines whether the node visibility should be taken into account by the animation algorithm (when it equals true) or not (when it equals false). The method fills a passed bool value with the current value of the visibility flag, then returns it to a calling subroutine.

The true value if the node visibility should be taken into account during the animation; otherwise, the method returns false.

The default implementation returns false. You should re-implement this method within a derived class and return true in it if you want the node animation algorithm to take the node visibility into account.
