I’d say this technology is at least worth checking out. About 2/3 of the way into the video, the guy shows off a composite model of the Notre Dame cathedral. The model was designed using pictures from Flickr. That’s awesome enough to border on the absurd. There’s some other cool things in the presentation but, as one of the many people who is computer literate but has no in-depth knowledge of computers, I have no concept of what kind of power these processes entail. Having gigabytes of pictures all up at once so that you can navigate and zoom smoothly doesn’t seem like the kind of thing my Dell laptop can do.
