What's your number? http://eporner.in.net/ eporner hd But is it an exact science? For instance, how "true" are the colours of the 3D furniture? I asked Ikea's augmented reality specialists in Sweden. At the moment, it's "as accurate as possible using the technology", but they admit there will be slight variation between the colour of the "generated" 3D sofa and how the real piece would look with your home lighting. The technology is advancing so fast, though, that limits will fall away in time. Currently, 90 products can be seen in 3D, but this could expand to whole roomsets. And inevitably, other brands will follow.
