Boolean operation graph

As shown in the figure below, A and B are two areas before the calculation, and the black point in B is the center of B. After the calculation, it is equivalent to use the center of B to go around the boundary of A, and the area scanned by the boundary of B is added. The area of A itself is the result of A expanding B.
