To test this model, change viewpoints and then try to navigate each time, noting the new navigation mode.'/>
  7            <meta name='info' content='NavigationInfo nodes have their own binding stack, similar to Viewpoint nodes, meaning that they can be activated (bound) in any order, but only one can be active at a given time. Cross-connecting a custom NavigationInfo to some Viewpoints can improve user experience in larger scenes.'/>
