In addition to expanding the methodology to three dimensions , the algorithm is drastically improved through ( 1 ) adopting a new overhang mapping scheme which allows for exact specification of allowable overhang angle , and ( 2 ) implementing an adjoint approach to sensitivity calculations to speed up calculation drastically and to allow for scalability .
