A simple example would be someone viewing a large indoor environment. Let's say you wanted to show them the second floor, or a room on the other side of the building. They cannot physically walk there, so you would move the virtual viewpoint origin to the other room, and now they can walk relative to the center of that room.
Realistically, you will never need to use the cave.update() function. There might be a case where someone would have to manually manipulate the tracking data before passing it on to the cave object. In this case they could manually update the cave after they have manipulated the data.
