What will be the value of new co-ordinates if the old co-ordinates are (X0 = 2, Y0 = 0, Z0 = 4) and the scaling factor is (Sx = 2, Sy = 1, Sz = 3)? a) (X1 = 4, Y1 = 1, Z1 = 7) b) (X1 = 0, Y1 = -1, Z1 = 1) c) (X1 = 1, Y1 = 0, Z1 = 4/3) d) (X1 = 4, Y1 = 0, Z1 = 12)
Answer: d Explanation: The new co-ordinates would be – (X1 = 4, Y1 = 0, Z1 = 12) Applying the scaling equations, we have- X1 = X0 x Sx = 2 x 2 = 4 Y1 = Y0 x Sy = 0 x 1 = 0 Z1 = Z0 x Sz = 4 x 3 = 12
