Hi all!

I would clarify problem about that Joshua Neil Rubin spoke:

        [something erased]

... and after that, i think that it's not pure problem for computer graphics
disciplines. I suspect that where are necessary not only *excelent*
graphic perfomance, but also AI tools. When you are getting such single
stereopar, we must decide, at minimum -

(a)     How much can we change point of view?
(b)     What distortions of made perspectives are suitable?
        and on the whole, how we can measure this "suitableness"?
        (i suspect also that it depend upon ****many factors.)
(c)     How can we will get another piece of data for composing
        perspectives if you want make it aside our pre-defined ranges?

If we want that system work reliably, we must provide there some
subsystems that will be solve such problems.

Can somebody say something about it? I hope.

(I must give hard apologys for my English to anybody who has read this.)
