Okay, I have to admit my ignorance. I don't know how modifying
the direction vector affects the image.

Yes, but like I said, there is no viewing system that takes
convergence into account. What you end up with is images
with angular distortion because they are rendered from the
perspective of converging eyes, but they are viewed in
parallel.
