“…If so, it computes the intersections and inserts them into corresponding edges. It does in this way, until all Black: (1,1)(4,1)(4,3)(a)(2,4)(2,3)(a)(1,2) Read: (2,2)(5,2)(a)(6,1)(6,3)(4,5)(a)(2,4.5) (1,4) P1: (10,10), (40,10), (40,30), (20,40), (15,30), (15,15) P2: (20,20), (45,20),(55,30),(50,50), (30,45) edges of P 1 are processed. The rest of steps are to assign the entry-exit properties and to traverse, which are the same as the ones of our proposed method.…”
