3D imaging isn't my normal beat, but the amount of development in this sector in the last few years is kinda impossible to ignore. I can't say exactly how this technology will be used in advertising, but I can say that it will-- it's too creatively ripe to stay in the land of video games and virtual apartment tours.
There's are some good thoughts on this here, and for an incredible example of where 3D imaging stands today, check out this tour of France's Grand Palais-- it'll make your eyebrows dance.
