Display caption

This lecture diagram shows that a perspective representation is equivalent to a tracing on a pane of glass between the artist and the object.
The artist is at a fixed point. He looks with one eye at the object (labelled BFDA). The object's perspective representation (labelled bfda) is formed where straight lines (representing rays of light) from the object to the artist's eye (E) pass through the picture (labelled OPRQ).
