I'm using a head-tracker and power wall setup. I use

vizcave.setTracker(tracker)

to allow the frustum to be automatically adjusted according to head-tracker coordinates. Alternatively, I could manually do this with

vizcave.update()

and an appropriate timer, though I'm not clear why this would be useful (the documentation does not explain this well).

But how should I deal with the viewpoint? From reading the documentation on sensors and linking it seemed to me that the appropriate way was to use

viz.link(tracker,viz.MainView)

but vizcave provides the

caveview = vizcave.CaveView(tracker)

view matrix, which I alternatively linked to the main view

viz.link(caveview,viz.MainView)

with no apparent difference. What is the appropriate way of updating the viewpoint? And are these two methods completely equivalent?
