How to construct the vanishing point of a line? (analytically and on paper)
A point and a direction
define the line
The standard projection of a point
results, after de-homogenization, in the point
on the image plane.
Thus,
Let us only examine the x-coordinate of this and rearrange some terms:
Now, if
