    Perspective Projection (PP)
    Perspective projection (PP) mimics the behavior of the human visual apparatus or a simple camera obscura. It models the visual field by projecting points onto a plane through a single, defined viewpoint, known as the Focal Node (\mathbf{F}$).
    The essential characteristic of PP is that the scale of an object is inversely proportional to its distance from the Focal Node (\mathbf{F}$). Mathematically, this involves…

    Ocular Anatomy and Photoreception
    The primary organ of vision is the eye, a complex structure that functions analogously to a biological camera obscura. Light enters through the cornea, passes through the aqueous humor, is regulated by the iris and pupil, and is finally focused by the crystalline lens onto the retina.
    The retina contains two primary types of [photoreceptor cells](/entries/pho…
