Acquire the perspective transformation, Computer Graphics

Assignment Help:

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:
