As a bit of a joint community project, I'd be interested to compare some photogrammetry software. I was thinking someone could provide a nice set of photographs and then we can all run our own software on it to generate a 3D model. If you want, you could post the 'raw' result and one after cleaning up (to show off your mad 3D skillz).
Maybe tell us a bit about what you ran into, how you solved it etc?
We could even do it a couple of times, using different sets of photographs to see which software works better for certain types of objects etc.
Who's up for the challenge?
