Principally it uses VisualSFM and Meshlab, both of which came to life as testbeds for algorithm research but are now useful in their own right. By all accounts 123D Catch does an excellent job, but is quite rigid in its workflow. Apparently it uses the engine from Acute3D's considerably more expensive Smart3DCapture. Sadly neither VisualSFM or 123D Catch are usable for commercial work because of license and copyright problems respectively.
