3D some sources

I have been sent a couple of links by Fabian King. He has guested on the Wild Show and has explained a lot about 3D scanning, an important topic for 3D printing. I had thought that scanning buildings in 3D would be very expensive. But he points out that there is software to make a model from photos.  123Catch has several examples such as the Flat Iron building. I have not yet worked out how to do this but have taken a photo of their model so could mix this into 2D images.

Also Google Maps now has a 3D aspect that you can choose as an extension of street view. This again is helpful for images that could be put together. I don't think there is much on Exeter yet but it could turn up later.
