;;; PURPOSE
;;; Controls a PolyView "flight" through the demo.hdf sample world.
;;; Camera tracks across field of tetrahedrons and through an aisle
;;; of them, stops at a wall and pans 270 degrees to its left, then travels
;;; through a tunnel of cubes and zooms up to view the world from on high.
;;; After a few orbits, it then flies back to its original position.

;;; Initialize Position to edge of array.
