REMARKS
The
human eye adjusts itself to focus close or distant images. The closest
point that we can precisely and sharply focus is 17cm away from our
eyes.
It is important
to stress that only the parallel (1 vanishing point) and the oblique
(2 vanishing points) perspectives will be worked in this closest point
of vision.
The aerial
parallel (2 vanishing points), the aerial oblique (3 vanishing points)
and the integrated (5 vanishing points) perspectives will be worked
in the space existing between the closest point of our vision up to
infinity. This space is called accommodation range. The aerial perspectives
image are focused very far away, dozens of meters away from our eyes.
The explanatory
graphs of these types of perspectives will enable a better understanding
of the process.
