In a correctly constructed computer graphic image, usually one may still recognize the shape of the objects despite their (from a mathematical viewpoint correct) perspective distortion. Our perception accepts distortions and interprets, for example, an object as a proper circle, although it looks like a distorted ellipse. However, based on the scientific common sense, one should question the "infinity" of such perception tolerance. Where do its limits lie? Which perspective distortion would still be acceptable, before our perception "fails" to recognize an object because of its strong distortion?
