I recall many years back a website, I think a Microsoft project, that linked together photos in a 3D space of tourist destinations. It created something of a point cloud, but nothing this advanced. You could click through the points/photos to jump into each photos perspective of the space.

Anyone remember what that project was called, or if it is even still around?

Edit: Found it. http://phototour.cs.washington.edu/ Later the discontinued. https://en.wikipedia.org/wiki/Photosynth
