In this sample we load an existing 3D scene and setup a locomotion graph, for a constrained navigation.
We add several locomotion nodes into the 3D space using ATON.Nav.addLocomotionNode(x,y,z)
The navigation system automatically selects the next node in sight, and users can simply teleport by using a double tap/click on the screen (or main trigger on VR controllers). This is useful to constrain first-person navigation into specific hotspots.
