Peter (on the Photosynth team) ran across the following wonderful piece of work: http://binarymillenium.blogspot.com/2... A number of you have asked about getting pointclouds out of Photosynth, and the clever binarymillenium has reverse-engineered how to parse it out! We should make the following caveats: a) binarymillenium isn't connected with Microsoft in any way (as far as we know :), and b) the format isn't yet documented or supported (we're working on it), so we can't yet guarantee that it'll be stable. But I'm sure there will be readers eager to try this out. (Binarymillenium, I hope you don't mind our reposting your screenshot!)
