**converge**because AB and CD are not parallel to the image plane . As AB and CD are produced vertically downward to infinity , the image traces of these lines**converge**at V- that is , when D1 and B1 are at infinity , LD1 and LB'coincide ...Page 9

**converge**with the image plane . It may be further deduced from Figure 7 that vertical lines do not**converge**on a vertical image plane whereas horizontal lines**converge**sharply . The latter is also evident in Figure 9. Lines A , B ,, A ...Page 10

**converge**at the nadir or on the horizon line . Consider two parallel lines , one passing each side of the observer and not parallel to either the observer's horizontal or vertical reference and making any angle with the observer's ...### Contents
