There is a machine in a certain wood window manufacturer's plant that I have toured, which uses lasers to measure odd pieces of wood and then table saws to cut them into necessary sized pieces, minimizing waste - even cuts for fingerjoints - it all happens on a moving belt, and it happens extremely fast and in real-time. I was impressed. Probably powered by something like this algorithm (or the MAXRECTS one)
