It's a pretty common thing in CG to use various image-based rendering (IBR) techniques to enhance backdrops with actual photography. The car-chase scene in Toy Story was like that too. I don't know how much was IBR and how much was modelled, but there's a HUGE middle ground between modelled and IBR. <a href="http://panoramas.dk">QTVR panoramas</a> are at one extreme end of the spectrum, and at the other end, there's video games which use scanned photographs for their textures and so on.Hoblit wrote:AND, I think that some of the city scenes were enhanced with rendered photography. Right now I'm guessing, but I'll look it up later. If it wasn't, then I'm betting that there were pictures taken and some of the 'set' was modeled after the photography. (which is probably the case actually)
David Fincher has made a lot of use of IBR in his movies, too... it was pretty obvious in Fight Club with the various impossible camera angles and compositing effects (like the walk-in Fürni catalog), but what most people don't realize is that pretty much all of the panned/tracked shots in Panic Room were IBR too (and I'm fairly certain that things like the propane torch scene were heavily enhanced with CG as well).
If you have the 2-disc collector's set version of Fight Club, I highly recommend watching the various special features which show how they did a lot of it. Even the penguin was done with some IBR-derived techniques (using lightfield acquisition to get the sheen of the feathers right, etc.).
My point being that it's pretty hard to define what's CG and what isn't these days. It's more of another tool for the effects artist and animator to use, rather than a means to an end. Which is how it should be. CG for the sake of CG is boring and makes things like the Mind's Eye videos and Final Fantasy: The Spirits Within — exciting to people who care about the tech, not so exciting once the tech isn't new anymore.
I mean, it's only been 3 years since FF:TSW but that movie already looks like crap... yet 9 years later the original Toy Story is still a great movie.
Also, is it just me or does Polar Express look only slightly better than a late-90s video game cutscene? When I watch the trailer I keep on expecting to see Atrus ask me to give him the pages or something.
