The input word … WebThe classical approach works ray-wise and uses pre-calculated ray-attacks for each of the eight ray-directions and each of the 64 squares. It has to distinguish between positive and negative directions, because it has to bitscan the ray-attack intersection with the occupancy in different orders.
