Looking through other people’s photos can be a bit boring at times, but imagine if you could walk through them. That’s what a new computer programme may enable people to be able to do, and it could be ready in 2006. Microsoft has come up with a way of matching up different images of a particular subject and then collecting them together in one virtual 3D model. A computer user could then walk or fly through the scene to look at any of the pics from any angle. The technology is expected to be available online, so people could upload their photos to a website, and then combined with other images, could produce a 3D model. The technology, called Photosynth, could also be used in tourism, with visitors able to take a virtual tour of some kind to see if they like the look of a place before they go.
