I am looking for a reasonable way to capture 3D models of people. Even capturing only a head and neck would be sufficient to print a "piano bust". I'm thinking a short video clip of the subject, moving around to get many angles, should be sufficient and convenient input. It could be captured quickly, with the subject reasonably motionless. AutoCad 123D Catch seemed promising, though it requires "about 40" discrete photos. It is not clear what resolution is needed. They say 3MB should be enough. However, I have not been able to get decent results even with inanimate objects. It seems that hours of effort, and attempts to follow their guidelines, only produce unusable results for me. Does anybody know of software or methodology that might work well?
