Acquire the perspective transformation onto z = - 2 Plane, where (0, 0, 18) is the center of projection.
Solution: Now centre of projection, C (a, b, c) = (0, 0, 18)
∴ (n1, n2, n3) = (0, 0, 1)
And Reference point is R0 (x0, y0, z0) = (0, 0, - 2)
∴ d0 = (n1x0 + n2.y0 + n3z0) = - 2
d1 = (n1.a + n2.b + n3. c) = 18
We know here the general perspective transformation while cop is not at the origin is specified by:
