A year or two back I had an opportunity to noodle and scratch my head on
this general topic. Attempting to do it with "conventional tools" was
essentially massive and required a dedication of people unrelated to the
actual value of the project: there was no easy way.
Then we ran on to an outfit that had been working many years to create the
development environment necessary to enable investment in the data,
processes, and delivery. There are several outfits that are doing this sort
of 3D-ization with fly through. Sounds simple but to get the "fly-through"
effects over accurate terrain that has necessary texture as well as snap
required SUN server and state of the are WINTEL. And it didn't quite work
well enough to get the $ need to continue on.
Well, times change and GHz WINTELS are normal as are 250GB disks and video
systems that could not even be purchased three years ago. SO... take a look
at the listed site below. Its taken its main contributor a "career" of
time, four VCs, and assorted minions. The opinion on the results I'll leave
for off-line.

Subject: GISList: visualisation
Dear all,
I would like some advice please.
I want to visualise some 3D terrain models. This is likely to include some
rotation, zooming in, development of fly-throughs and later, addition of
textures to make the scenes more 'life-like'. I have built the DEM from UK
Ordnance Survey (the UK's national mapping organisation) data and I have
draped raster files over the top (several big TIF files).
Currently I am using ArcScene to enable my visualisation, but there seem to
be limits to the program. Part of the problem is that my graphics card is
unable to cope with the data volumes, but the process of developing
fly-throughs seems to be quite long-winded (export of individual scenes to
another software package etc.) and adding textures is, as far as know,
impossible.
I am limited to using ArcGIS for our GIS processing, but we have some money
available to buy visualisation software. Does anybody have any thoughts,
experiences, comments on visulisation software of GIS data.
Many thanks in advance
John
