Wouldn't these problems dissolve once cameras where objects,
that could move around. Together with composites I would model
a rollercoster or ferrywheel with composites for the 'waggons',
which move around. And to take a ride on the rollercoster,
the camera (my eye) would be placed in one of waggons.
Doing all the move the composite does.
