How can I use ray tracing techniques to directly generate
binary holograms which reconstruct into the usual kinds of
ray traced images?  I think it would be amazing indeed to
view a reconstruction of the usual kinds of mirrored and
refractive spheres that behaved as if it were really there!

I've been reading a couple of articles:

	_Binary Fraunhofer Holograms, Generated by Computer_
		A. W. Lohmann and D. P. Paris
		Applied Optics Vol 6, No 10 p. 1739
and:
	_Minimization of Reconstruction Errors with 
        Computer Generated Binary Holograms_
		R. A. Gabel and B. Liu
		Applied Optics Vol 9, No 5 p. 1180

I'm inspired by the cover of Stewart Brand's new book, _The Media Lab_

Any information which might help me understand this technology is welcome.
