TUGAS PENG. GRAFIK KOMP. & OLAH CITRA

SOAL :

P1 = (13,9)
P2 = (20,17)

JAWAB :

∆χ = (χ₂ – χ₁)
= 20 – 13
= 7
∆У = (У₂ – У₁)
= 17 – 9
= 8
2∆У = 2 . 8
= 16
2∆У - 2∆χ = 16 – 14
= 2
P_o = 2∆У - 2∆χ
= 16 – 7
= 9

Jika Pk kurang dari 0 (nol) , maka :

Plot (χ _k+1 , У _k+1) & Pk+1 = Pk + 2∆У - 2∆χ

diulang 4 ∆χ kali, sampai (χ-χ & У-У)

K	Po	(χ k+1 , Уk+1)
0	9	(14,10)
1	11	(15,11)
2	13	(16,12)
3	15	(17,13)
4	17	(18,14)
5	19	(19,15)
6	21	(20,16)
