Lesson 2 – The Restricted Sight

lesson_02

In the Restricted Sight, any point of the Perspective corresponds to a point of the Model.
E.g. point A’ is the perspective of point A, point B’ is the perspective of point B … and so on.
If you want to know how to fix the eye position with respect to the drawing, read the Lesson 03.

Now, imagine displacing your eye, for instance, lower. In this case any point of the Perspective corresponds to a point of another, and different, Model.

If you want to explore the Restricted Sight read: Perspective: Theories and Experiments on the “Veduta Vincolata” (Restricted Sight) by R. Migliari and J. Romor

If you want to explore what happens when you displace your eye (centre of projection), you can read, too: Vecchi, S., La teoria geometrica attuale delle restituzioni prospettive riveduta e  corretta. Memoria sulle impressioni diverse che producono le prospettive ed i bassorilievi quando venga a cambiare la posizione del punto da cui si guardano, Parma 1885.
