Not really true.  I think that criteria for judging 3-D imagery have to
be developed.  I won't even try to inumerate the criteria.  Many companies
try to render the color mandrel.  By chance it had some characteristics:
color, fine resolution, etc.  I think we have to develop some test case
pieces.  You must view a lot of 3-D before judging the quality
(different systems) of good holograms.  If you don't, you will get spoofed.
Please, continue this discussion on comp.graphics.  We have to think about
the issue.

BTW there exist quite a series of Voyager holographic "movies" going
back to Jupiter.  I won't try to justify why the Lab doesn't put the
current set of images on the net except to say it gives something to
people like Ed Stone, Brad Smith, and the rest of the investigators who
pushed for this mission in 1972: tenure.  The cost of these is about $500
a copy contact the Lab.  We as US taxpayers may have
paid for the mission, but an agreement was made with these men who
proposed this mission at a time when space was not popular: we give you access
to this data for a year in advance of your colleagues for your time in
the management of this mission.  We as readers should respect this.
Some people see this as PR, these men see this as their data and their
livelihood.  Remember this when you FTP these images which will
eventually get out (and your can get the earlier planets right now).
If you want to argue this, follow up to sci.space, not comp.graphics.

Another gross generalization from
