Principal vanishing point write respect to Z-axis
Principal vanishing point w.r.t z-axis:
By the 3rd row of matrix equation, we declare that the principal vanishing point with respect will as:
((-5/2), ((-5√3)/(2√2), 0 , (√3/(2√2))) in homogeneous system.
The vanishing point, in Cartesian system is written as:
