Many years ago there was a 3D view of a recreation of the interior of
Dresden Cathedral using then-state-of-the-art Catia software, described

"After the completion of this animation we discovered that
we had created a new problem, which is "How can a com-
puter reconstruction, which is a new archaeological docu-
ment in its own right be itself conserved for future
generations?". Computer hardware and software evolve and
change at such a rate that it will most probably be impossi-
ble to render these images on computer systems even in the
near future.
A possible solution would be to preserve the computer
system which was used for each animation that is produced,
but that would ultimately become too expensive to main-
tain in working order. The only practical solution at present
would be to render these images at the maximum resolu-
tion possible and record them onto a medium such as 35mm
cine-film or CD-ROM which has a reasonably long shelf
life. We hope that this will be possible with this project."
